August 2009-Dr. Fu receives award to support his lymphoma research

Story contributed by the Lymphoma Research Foundation

 
 New ways to attack an aggressive and incurable type of lymphoma will be studied at UNMC with the help of a $300,000 grant from the Lymphoma Research Foundation (LRF).
Kai Fu, M.D., Ph.D., associate professor of pathology and microbiology, has received the grant — called the 2009 Millennium Pharmaceuticals, Inc./Lymphoma Research Foundation Clinical Investigator Career Development Award — to support his mantle cell lymphoma research.   This substantial investment by the Lymphoma Research Foundation is indicative of the group’s high esteem for Dr. Fu’s work, said Tom Rosenquist, Ph.D., vice chancellor for research at UNMC.  
 

More about the award

The three-year Clinical Investigator Career Development Award is designed to fund training of clinicians who will participate in developing new therapeutics and diagnostic tools for lymphoma.

The focus of the training is to prepare clinicians to design and administer clinical studies in lymphoma and to take on the primary responsibilities for clinical trial design, protocol writing, Institutional Review Board (IRB) submission, and publication.

Dr. Fu will pursue a career development plan with the guidance of his mentor, Wing (John) Chan, M.D., Amelia and Austin Vickery Professor of Pathology and co-director of the UNMC Center for Lymphoma and Leukemia Research.

“Dr. Fu has been highly productive in lymphoma research and I am glad that his potential as a physician-scientist is recognized by the LRF with a career development award,” Dr. Chan said. “We are grateful for this award that will provide essential supports during his transition to be an independent investigator.”

“I know that, with his innovative research approach and high level of energy, the investment will pay dividends in new, improved therapy for patients with mantle cell lymphoma,” he said.  

Lymphoma — the most common type of blood cancer — is broadly categorized into Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). According to the World Health Organization, there are six types of HL and more than 61 types of NHL.  

Mantle cell lymphoma is a rare B-cell NHL that is very aggressive. It accounts for 6 percent of all new diagnoses of NHL — or about 3,000 new cases per year in the United States. 

The disease:

  • Typically affects men older than 60;
  • Frequently is diagnosed in Stage IV;
  • Often is present in lymph nodes above and below the diaphragm; and
  • In most cases involves the gastrointestinal tract and bone marrow.

It is characterized by over expression of the gene called cyclin D1 due to a chromosomal translocation. 

A subset of mantle cell lymphoma also shows higher levels of a group of small RNA molecules, called miR-17~92. 

Dr. Fu and his colleagues have found that this higher expression correlates directly with poorer patient survival. These findings indicate that higher miR-17~92 expression induces abnormal activation of a pathway in tumor cells that leads to increased resistance to standard chemotherapy.  

About the foundation

The Lymphoma Research Foundation (LRF) is the nation’s largest voluntary health organization devoted exclusively to funding lymphoma research and providing patients and health care professionals with critical information on the disease. LRF’s mission is to eradicate lymphoma and serve those touched by this disease.

As of June 30, 2008, LRF had funded more than $37 million in lymphoma-specific research. The foundation is the world’s largest private funder of mantle cell lymphoma research.

 

This recent award will help Dr. Fu conduct a pre-clinical study to determine whether suppression of miR-17~92 will improve the effect of chemotherapy. His study may lead to a novel approach to treat MCL patients.

“Dr. Fu’s elegant proposal explores a new avenue for understanding MCL and identifying potential therapeutic targets,” said Michael Williams, M.D., director of the University of Virginia’s Hematologic Malignancy Program and chairman of the LRF’s Mantle Cell Consortium, of which Dr. Fu also is a member. “We are delighted that Dr. Fu has chosen MCL as the focus of his Clinical Career Development Project.”

May 2009-Dr. Fayad named AHA Physician of the Year

Story contributed by The American Heart Association

Pierre Fayad, M.D., Reynolds Centennial Professor and chairman in the UNMC Department of Neurological Sciences, has been named the American Heart Association Physician of the Year.

 

Dr. Fayad — who also is director of the stroke center at UNMC’s hospital partner, The Nebraska Medical Center — received the award during a ceremony in Washington on Monday.

 

The award is conferred annually upon the practicing physician who has rendered “outstanding contributions” toward accomplishing the American Heart Association mission. Dr. Fayad was honored for being a pioneer and leader in numerous initiatives to improve the health of his community, especially in the area of stroke.

 

“This is a wonderful honor for one of our truly outstanding physicians,” said John Gollan, M.D., Ph.D., dean of the College of Medicine. “Dr. Fayad’s work in the field of stroke certainly merits this national recognition.

 

“This is excellent news for Dr. Fayad, the College of Medicine and UNMC as a whole.”

 

As stroke center director, Dr. Fayad established and now leads a stand-alone outpatient neurological clinic that received more than 7,000 patient visits in 2008. He also oversees a multidisciplinary “Stroke Code Team” that is responsible for the care of patients with acute stroke.

 

Countless patients have benefited from Dr. Fayad’s neurological expertise, including Lenice Hogan of Omaha.

 

“I have a complicated medical history and every time I was in the hospital I was told something different and would leave with no idea what the problem was or where to turn,” she said. “From the moment I met Dr. Fayad, I felt absolutely at ease. He took my records and spent a month researching other patients in the world with my condition — he found three. I’m not scared of what lies ahead because I know he’s on top of everything.”

 

Brenda Barry of Woodbine, Iowa, credited Dr. Fayad with saving her husband Lynn’s life.

 

“My husband had been having a series of mini strokes for a few weeks,” Barry said. “They would hit him for a few minutes and then he would go about his day like nothing had happened. We knew it wasn’t normal, but it was easy to let it go.”

 

Until they met with Dr. Fayad.

 

“In our initial appointment with Dr. Fayad, he was very thorough and quickly diagnosed the seriousness of the situation,” Barry said. “As far as we’re concerned, he saved my husband from having a massive stroke that could have paralyzed or killed him. Lynn is healthier than he has been in a decade or longer.”

 

Under Dr. Fayad’s leadership, the medical center’s stroke center became the first in Nebraska to be certified as a Primary Stroke Center by the Joint Commission.

 

In 2008, The Nebraska Medical Center was recognized with the Gold Achievement Award of the American Heart Association’s Get With The Guidelines-Stroke program, which recognizes 24 consecutive months of providing care that meets or exceeds stroke treatment guidelines set by the association.

 

Stewart Becker of Omaha suffered a stroke while on a skiing vacation in Colorado. After a week in a Denver hospital, he came home to Omaha and met with Dr. Fayad.

 

“The perception was that in the middle of the country I wouldn’t have the resources I needed (as a stroke survivor),” Becker said. “In Dr. Fayad, I’ve got an individual with a great reputation with a great institution, and I can get as good of care right in my home city as I could get anywhere.”

 

Dr. Fayad currently chairs the Advisory Committee of the American Stroke Association, a division of the American Heart Association. He is also a member of the association’s International Stroke Conference Program Committee and National Science Advisory & Coordinating Committee.

January 2009-Medical center ranks as top hospital for nursing

by Andrea McMaster, The Nebraska Medical Center 

UNMC’s hospital partner, The Nebraska Medical Center, has been named one of the 2009 ‘Top 100 Hospitals’ for nurses to work for by Nursing Professionals magazine. The Spring 2009 Top 100 Hospitals issue is now available.

 

The Nebraska Medical Center placed 43 in the ranking and joins a select group of hospitals such as Abbott Northwestern Hospital in Minneapolis, Barnes-Jewish Hospital/Washington University in St. Louis, Brigham and Women’s Hospital in Boston and the Cleveland Clinic in Cleveland.

 

 

“The Nebraska Medical Center appreciates and promotes a strong nursing care delivery model,” said Rosanna Morris, senior vice president and chief nursing officer at The Nebraska Medical Center. “The hospital ensures that nursing has a seat at every table where decisions are made not only organizationally, but particularly those that impact nursing practice and patient care.

 

“Support, recognition and promotion of the value of the nursing profession at The Nebraska Medical Center is what sets us apart from other organizations.”

 

 

Hospitals are selected based on a survey that is sent out to 25,000 randomly selected hospital nurses throughout the country that measures their job satisfaction. The survey featured questions such as, “How well does your hospital manage personal training and development?” and “Is your hospital a family-friendly employer?”

 
News of The Nebraska Medical Center’s award did not come as a surprise to many nursing staff.

 
“The thing that impresses me the most about working at the medical center is how much management involves nurses in decisions that affect us,” said Missy Schreiber, a staff nurse in the cancer care area at The Nebraska Medical Center for the past 21 years. “The hospital realizes nurses are the front line to patients and they want us to our job well and to do that, we have to have the right tools and resources.”

 
Mike Diggins, an emergency department nurse at The Nebraska Medical Center for 23 years, agreed.

 
“Nurses have a large voice in the hospital and that is supported by management’s open door policy,” Diggins said. “I can talk to my manager or director anytime. They welcome my input and they often will act upon it if they feel it’s valid.”

 
Diggins, who works three 12-hour weekly shifts, said the opportunity to have a flexible work schedule that fits his needs and allows him to have a balanced family and work life, is another attractive aspect of working at The Nebraska Medical Center.

 
“The hospital staff support me 100 percent when I’m here, but when my shift is over, I can leave my phone behind and focus on my family,” he said. “We truly have a state-of-the-art facility, so when I’m here, I know I have the equipment, tools and personnel to do my job well and provide exceptional nursing care.”

The support of education and of professional growth has been attractive factors for Schreiber.

 

“Support, recognition and promotion of the value of the nursing profession at The Nebraska Medical Center is what sets us apart from other organizations.” Rosanna Morris

 
“I’ve always been encouraged to participate in conferences, certifications and other educational opportunities,” Schreiber said. “The medical center wants nurses to be knowledgeable and current because that directly relates to how we care for our patients and allows us to provide the most current and up-to-date care.”

 

 

The working relationship between nurses and doctors is also important, Diggins said.

 
“The physicians respect our skills and judgment and rely on our input,” he said. “It is very much a team environment.”

 
A recent testament to nursing satisfaction at The Nebraska Medical Center was the hospitals “60 Nurses in 60 Days” recruitment campaign this past summer, which ended with 90 nurses joining the organization.

 
“A great majority of these nurses were from the local area and came with previous experience,” Morris said. “One of the greatest outcomes of this campaign, in addition to surpassing the initial goal, was that every one of the new nurses had been internally referred by a medical center employee.

 
“We are very pleased that our staff has such confidence in this organization to refer individuals that they knew to become a part of our team.”

December 2008-Bone marrow transplant program celebrates 25 years

Twenty-five years — 4,000 transplants.

 

UNMC and its hospital partner, The Nebraska Medical Center, are celebrating a significant milestone this year.

 

The bone marrow and stem cell transplant program at the medical center, known for its innovation and success in stem cell transplantation, is celebrating its 25-year anniversary.

 

The program was founded in 1983 by James Armitage, M.D., Shapiro Professor of Medicine at UNMC and hematologist/oncologist at The Nebraska Medical Center, who is world renowned for his clinical research in lymphoma and bone marrow and stem cell transplantation.

 

“Jim and his team always wanted the transplant program to be the best in the world and it has become the best,” UNMC Chancellor Harold M. Maurer, M.D., said Wednesday at a ceremony commemorating the program’s 25th anniversary. “(The program is made up of a) marvelous team of people that cannot be duplicated very easily anywhere else.”

 

Drawing patients from around the world, the program is ranked as one of the busiest adult lymphoma and pediatric programs in the country. The program averages 150 transplants a year and has performed more than 4,000 transplants since its founding.

 

There are many reasons why people come from around the world to receive care from the medical center’s transplant program.

 

Since its founding 25 years ago, physicians and researchers in the program have been pioneers in the field and have been recognized internationally for a number of ground-breaking advancements.

 

These advancements have helped improve success rates and have made bone marrow and stem cell transplants a more viable and promising option for a growing number of patients. This includes those with malignancies that include primarily lymphomas, leukemias, multiple myeloma as well as some blood disorders.

 

The first of these revolutionary achievements was the study and introduction of autogolous transplantation by Dr. Armitage and his colleagues, which served as the starting point and foundation for the program’s success.

 

“At the time, bone marrow transplants were still a very new thing,” Dr. Armitage said. “Allogeneic transplants, in which stem cells are harvested from a donor, were increasingly being done, but they were quite dangerous and risky. We wanted to find a way to help people who had otherwise incurable lymphoma. So we developed a hypothesis and began testing autogolous transplants as another option for these people.”

 

Autogolous transplants involve using the patient’s own stem cells, which reduces the complexity of the procedure and eliminates rejection issues such as graft versus host disease. This condition, which Dr. Armitage said occurs in more than half of all allogeneic transplants, happens when the new immune cells recognize that they are not in the right body and attack the other cells of the body.

 

Today, autogolous transplants are the preferred form of transplantation for more than 75 percent of lymphoma patients, he said.

 

Another milestone in the field of bone marrow and stem cell transplantation was the development of stem cell transplantation, which was introduced in 1984 by Anne Kessinger, M.D., professor of oncology/hematology at UNMC and a hematologist/oncologist at The Nebraska Medical Center.

 

The use of peripheral blood-derived stem cells, as opposed to bone marrow-derived stem cells, has become the standard of care for transplantation. This has helped improve outcomes for autogolous transplant patients, contributed to much quicker recovery times and decreased infection rates.

 

Peripheral blood-derived stem cell transplant is similar to bone marrow transplant except the cells are collected from those circulating in the blood rather than bone marrow. Bone marrow is the spongy tissue found inside the bones. It produces the body’s blood cells and cells of the immune system. The blood cells of the bone marrow, white blood cells, red blood cells, platelets and others, all come from one type of cell called the stem cell.

 

The process for removing stem cells is much easier, quicker and more comfortable for the patient, said Julie Vose, M.D., chief of hematology/oncology at UNMC. For instance, bone marrow removal required general anesthesia and was performed by using numerous needles to inject the patient until enough marrow had been withdrawn.

 

In comparison, stem cells are removed during a two- to three-hour procedure in which a catheter is placed into the chest and inserted into a large blood vessel. The blood is circulated through a special machine that separates out the stem cells from the rest of the blood. The stem cells are then frozen and stored until they are ready to be re-infused back into the patient.

“Research is critical. As leaders in research, we are able to offer our patients new and promising therapies before anyone else. You can either watch others do it or you can be the ones doing it, and we are definitely leaders in this area.”
– James Armitage, M.D.

 

Physicians and researchers at UNMC and The Nebraska Medical Center also have been extensively involved in the study and use of colony stimulating factors, also called growth factors. Growth factors are drugs that are used to stimulate the growth of cells before the collection of stem cells and are used during and after transplant.

“By being able to stimulate and increase the growth of stem cells after transplant, today we are seeing decreased infections, lower death rates, fewer transfusions and reduced recovery time in the hospital,” Dr. Vose said.

 

Other important treatment advancements that have had a significant impact in improving the outcomes for patients, Dr. Vose said, include improvements in supportive care techniques, anti-rejection medications and the ability to prevent and treat complications, especially infections.

 

“Twenty years ago, 30 to 40 percent of adult patients died from complications of an autogolous transplant,” she said. “Today, that number is down to 1 to 2 percent.”

 

In addition, adult transplant candidates used to be limited to those younger than 60 years of age. Today, transplants are performed on individuals as old as 75 years old. Survival rates average 50 to 60 percent, depending on the type of malignancy, compared to approximately 20 to 40 percent 10 years ago.

 

“Research is critical,” Dr. Armitage said. “As leaders in research, we are able to offer our patients new and promising therapies before anyone else. You can either watch others do it or you can be the ones doing it, and we are definitely leaders in this area.”

 

Pediatric transplants are another component of the bone marrow and stem cell transplant program. Started in 1987 by Peter Coccia, M.D., vice chairman of the department of pediatrics at UNMC and chief of pediatric hematology/oncology at The Nebraska Medical Center, the program has performed more than 335 transplants. Transplants in the pediatric population are normally reserved for patients with more aggressive disease and are far less common than adult transplants.

 

The majority of pediatric transplants are performed on patients with acute lymphoblastic leukemia. More than 80 percent of these patients will be cured with conventional chemotherapy, said Al Grovas, M.D., hematologist/oncologist at UNMC and The Nebraska Medical Center and clinical director for the pediatric bone marrow and stem cell transplant program, leaving about 20 percent of patients who will need a stem cell transplant.

 

“The knowledge curve has risen steadily since the first pediatric transplant in 1987,” Dr. Grovas said. “And with that, improved success rates have followed suit.

 

“The Nebraska Medical Center program is unique in that it shares the same transplant unit as the adult program. This provides us the advantage of sharing all of the same resources and the expertise of our experienced nursing staff and other health care professionals.”

 

-Dr. Armitage with Nancy Wurtele of Nebraska City, who was the second person to receive a transplant through the bone marrow and stem cell transplant program.

 

The program also is part of the National Institutes of Health/National Cancer Institute Bone Marrow Transplant Clinical Trials Network. This is a consortium of 16 transplant centers across the country that collaborate on clinical trials in order to derive data from a larger population of patients and to allow for greater sharing of information between centers.

 

Through this network, doctors can study and refine their techniques to diagnose, treat and follow patients to provide them with optimal care.

 

The medical center’s program is the only one of its kind in the region, said Theresa Franco, executive director of the cancer program.

 

“We have experienced physicians focused around specific diseases, an investigational mentality and pioneering treatments,” she said. “We have built this program on total commitment, total expertise and total engagement of our patients and families.”

 

Dr. Armitage said his ultimate hope is that the bone marrow and stem cell transplant program will some day go out of business.

 

“Because that would mean that we had learned enough about treating these cancers that patients would no longer need transplants,” he said.

 

And you can be sure that Dr. Armitage and researchers at UNMC and The Nebraska Medical Center will have played a major role in that scenario should it some day come to fruition.

July 2008-Story contributed by The Nebraska Medical Center

Story contributed by The Nebraska Medical Center
 
Complex and rare cancers comprise approximately 15 percent of new cancer cases each year, making it difficult for patients to locate or research facilities with oncologists or surgical teams that are experienced in treating these specific malignancies.
Blue Cross and Blue Shield of Nebraska has named UNMC’s hospital partner, The Nebraska Medical Center, as a Blue Distinction Center for Complex and Rare Cancers.

 

Only 88 other medical centers in the United States have earned the same distinction.

 

Blue Distinction Centers for Complex and Rare Cancers were developed in strategic collaboration with the National Comprehensive Cancer Network (NCCN) with input from a panel of leading clinicians and professional organizations.
The NCCN is an elite group of 21 cancer centers across the United States, of which The Nebraska Medical Center is the only one in the region.

 

Peter Coccia, M.D., a pediatric oncologist at UNMC and The Nebraska Medical Center and member of the board of directors of NCCN, said, “We are very pleased to receive the Blue Distinction designation. As a founding member of the NCCN and as a National Cancer Institute Designated Cancer Center, it re-enforces our reputation as a nationally recognized referral site for rare and complex cancers. This designation and our recent award of being named one of the top 50 cancer care hospitals in the U.S. truly set this medical center apart.”

 

“Blue Distinction reflects the commitment of the entire organization to provide extraordinary care,” said Glenn Fosdick, president and CEO of The Nebraska Medical Center. “We care for some of the most seriously ill patients in the region. Our clinicians have worked diligently to make this one of the elite centers in the United States for these rare and complex cancers.”

 

“We want to recognize and reward those network providers who are setting new standards of excellence in the quality of health care,” said Dr. Bill Minier, chief medical officer at Blue Cross and Blue Shield of Nebraska. “Cancer touches the lives of so many Nebraskans. We are thrilled at the level of outstanding specialty care available to our members right here in our state.”

 

Blue Distinction Centers for Complex and Rare Cancers are facilities within participating Blue Cross and Blue Shield network service areas that offer comprehensive inpatient cancer care programs for adults, delivered by multidisciplinary teams with subspecialty training and distinguished clinical expertise in treating the following complex and rare subtypes of cancer:

 

Bone cancer;
Brain cancer;
Esophageal cancer;
Gastric cancer;
Head and neck cancers;
Liver cancer;
Pancreatic cancer;
Rectal cancer;
Soft tissue sarcomas;
Thyroid cancer; and
Acute leukemia.
The Blue Distinction Centers for Complex and Rare Cancers designation is focused primarily on multidisciplinary treatment planning and complex, major surgical treatments.

 

Among other selection criteria, The Nebraska Medical Center met the following thresholds necessary to be named as a Blue Distinction Center for Complex and Rare Cancers:

Has multidisciplinary team input, including sub-specialty trained teams for complex and rare cancers and demonstrated depth of expertise across cancer disciplines in medicine, surgery, radiation oncology, pathology and radiology;
Demonstrates ongoing quality management and improvement programs for cancer care;

Demonstrates an ongoing commitment to using clinical data registries and providing access to appropriate clinical research for complex and rare cancers.
Demonstrates sufficient volume of experience in treating rare and complex cancers.
Blue Distinction is a designation awarded by Blue Cross and Blue Shield of Nebraska to medical facilities that have demonstrated expertise in delivering quality health care. The designation is based on rigorous, evidence-based selection criteria established in collaboration with leading clinicians, medical societies and professional organizations.

The Nebraska Medical Center recognizes that the majority of patients’ multidisciplinary treatment may be best accomplished by integrating the expertise available in a Blue Distinction Center with locally available treatment resources, especially for outpatient chemotherapy and radiotherapy, based on individual circumstances and patient preference. Optimal support of a patient’s comprehensive cancer care needs may be achieved by coordination of care between the patient and their family, local physicians, The Nebraska Medical Center and Blue Cross and Blue Shield of Nebraska.

February 2008 Special Report-UNMC researchers: Estrogen derivative may initiate certain cancers

by Vicky Cerino, UNMC public affairs
 
UNMC researchers are part of a team that studied simple urine samples and found that certain estrogen derivatives can react with DNA to cause damage that may initiate breast, prostate and other cancers.

 

These findings — which are published in the Dec. 20 issue of the International Journal of Cancer — could result in better assessment of cancer risk and prevention, the researchers said. The team published similar findings in the journal The Prostate in 2006.

 

“We have a novel approach to cancer. We know the initiating step,” said Ercole Cavalieri, D.Sc., a professor at the UNMC Eppley Cancer Center. “We think prevention of cancer can be solved by eliminating this initiating step.”

 

The team’s findings were confirmed in a second, larger study and presented at a recent gathering of international scientists and physicians in San Antonio.

 

The study involves researchers at UNMC, Mayo Clinic and the Italian National Cancer Institute. The majority of the study was funded by a U.S. Army Breast Cancer Research Program Center of Excellence Award.

 

Estrogens can initiate cancer when natural mechanisms of protection do not work properly in the body, allowing estrogen metabolites to react with DNA.

 

“If these protections are insufficient, due to genetic, lifestyle or environmental influences, we think cancer can result,” Dr. Cavalieri said. “Now that we have the basic knowledge about this unifying mechanism of cancer initiation, we have a greater sense of urgency to assess people at risk and, at the same time, begin studies of prevention by using specific natural compounds.”

 

The screening test developed by the researchers analyzes estrogen metabolite profiles in humans and can simultaneously associate the profile with one’s risk of getting breast cancer. It involves testing a one-ounce sample of urine using a sophisticated method called tandem mass spectrometry, which analyzes about 40 estrogen-related compounds, including estrogen-DNA adducts formed by a chemical reaction of estrogen metabolites and DNA.

 

“We know the initiating step. We think prevention of cancer can be solved by eliminating this initiating step.”
Ercole Cavalieri, D.Sc.

 
Researchers analyzed estrogen-DNA adducts from 46 women with normal risk for breast cancer, 12 women at high risk of developing breast cancer, and 17 women diagnosed with breast cancer.

 

They found women at high risk of breast cancer and the women with breast cancer had significantly higher levels of the estrogen-DNA adducts in their urine samples, while the women with normal risk for breast cancer had low levels of the DNA adducts in their urine.

 

Nilesh Gaikwad, Ph.D., a UNMC researcher who developed the methodology for the screening tool, said the simple, non-invasive test could easily be applied in the clinical setting.

 

“We have found the first step that starts a cell down the road to becoming a cancer cell,” said UNMC research collaborator Eleanor Rogan, Ph.D. “By preventing this first step from happening, we think we can stop the development of breast or prostate cancer. The combination of an early detection test for cancer risk with administration of preventing agents should enable us to significantly reduce the number of women and men that develop breast or prostate cancer.”

 

The results are exciting because they show women at high risk of breast cancer can be identified by the level of adducts in a urine sample, researchers said.

 

“Similarly, initial studies in men have shown that healthy men have relatively low levels of estrogen-DNA adducts in their urine samples, but men with prostate cancer have much higher levels of the estrogen-DNA adducts in their samples,” Dr. Cavalieri said.

 

Researchers can use these estrogen-DNA adducts as a measure of cancer risk, he said.

 

“In addition,” Dr. Cavalieri said, “we have begun to establish how effective natural compounds may be at preventing cancer by determining their ability to reduce the levels of these adducts in urine.”

 

Dr. Cavalieri also said accumulating evidence suggests that specific metabolites of estrogens, if abundantly formed, can become cancer-initiating agents by reacting with DNA and generating mutations leading to cancer.

 

DNA is composed of four bases called adenine, guanine, cytosine and thymine.

 

He said estrogen metabolites react predominantly with the first two DNA bases, adenine and guanine, to form estrogen-DNA adducts.

 

The resulting damage generated by the reaction can give rise to mutations that eventually initiate cancer. The important estrogen-DNA adducts spontaneously fall out of the DNA, leaving behind gaps that generate the cancer-initiating mutations.
The estrogen-DNA adducts eventually make their way out of cells and are excreted in urine.

 

“This finding identifies a new biomarker in the urine, which appears to correlate with a women’s risk of developing breast cancer,” said Kenneth Cowan, M.D., Ph.D., director of the UNMC Eppley Cancer Center. “While these studies need to be confirmed in a prospective study in a larger group of patients, this could become an important screening assay for women and could lead to new therapies to prevent breast cancer.”

 

Dr. Cavalieri said one of the major obstacles in cancer research is related to the concept that cancer is a problem of 200 diseases — a viewpoint that has impeded researchers from looking at the origin of cancers because the search would be prohibitively complex.

 

While the expression of various cancers coincides with the concept of 200 diseases, some scientists consider there to be a common origin for many prevalent types of cancer. There is widespread agreement in the scientific community that cancer is triggered by genetic mutations in critical genes, he said.

 

“The article is the best example of translational research. They have generated a unified concept of carcinogenesis and obtained a practical marker detectable in the urine of breast cancer patients,” said Jose Russo, M.D., senior member, at the Fox Chase Cancer Center in Philadelphia. “This article provides the adequate setting to explore this concept further by laying the basis to prepare a set of prospective clinical trials testing the preventive effects of the agents or mixtures of agents that can intercept the initiation event in breast or other cancers.”

 

The work represents a paradigm shift in detection of cancer risk in humans and provides the earliest possible rational marker for prevention strategies and regimens, said David Longfellow, Ph.D., president and chief executive officer of the Toxicology Forum — an international, nonprofit organization devoted to conducting open dialogues about problems in toxicology.

 

“This work conveys a very exciting message — that breast and prostate cancer risk can be identified years before the development of a tumor and suggests that natural preventive agents may be effectively used to prevent the initiation step in cancer,” Dr. Longfellow said. “Although this is a single manuscript, it is based on an extensive body of work in animal models and humans that consistently supports these findings and is complemented by collaboration with many international cancer scientists.”

February 2008-UNMC physicians on Best Doctors list

by Elizabeth Kumru and Ann Lawlor, UNMC Public Affairs

A total of 280 UNMC physicians, including 150 full and part-time faculty, have been recognized on this year’s list of the Best Doctors in America.

 

The Best Doctors in America 2007-2008 database contains the names and professional profiles of approximately 35,000 physicians in the United States in more than 40 specialties, or the top 3 percent to 5 percent of specialists in the country.

 

“Our UNMC faculty are truly outstanding clinicians. The Best Doctors recognition once again reaffirms that our patient care and teaching facility is world-class,” said UNMC Chancellor Harold M. Maurer, M.D.

 

UNMC College of Medicine Dean John Gollan, M.D., Ph.D., agreed.

 

“Quality patient care is a top priority,” he said. “As an academic health sciences center, our faculty stay abreast of the latest medical advances and are involved in discovering new therapies. Our patients receive exceptional care and our students train with, and learn from, the best.”

 

“Our UNMC faculty are truly outstanding clinicians. The Best Doctors recognition once again reaffirms that our patient care and teaching facility is world-class.”

The UNMC physicians practice at UNMC’s hospital partner, The Nebraska Medical Center.

 

Physicians are selected on the basis of the question: “If you or a loved one needed a doctor in your specialty, to whom would you refer them?” A peer-review survey by thousands of doctors determines the doctors included in the database. Only those doctors who earn the consensus support of their peers are included and only physicians in the Best Doctors database are allowed to receive the survey, nominate others and vote.

 

Two renowned physicians affiliated with Harvard Medical School founded Best Doctors in 1989. Today, it is among the leading resources for more than 10 million people in 30 countries who are seeking expert medical resources and guidance to treat illnesses and injuries of all kinds.

October 2007-National journal spotlights Dr. Fox's embryonic stem cell work

by Tom O’Connor, UNMC public affairs

 

Thanks in large part to the work of a UNMC scientist, an international group of researchers has demonstrated that embryonic stem cells can be converted into liver cells and used to restore liver function in mice with liver failure. The findings are reported in the Nov. 5 issue of Nature Biotechnology, the leading international science journal in the field.
 

Ira Fox, M.D., McLaughlin Professor of Surgery and senior associate dean for research in the UNMC College of Medicine, served as the senior author on the article and headed the study along with Naoya Kobayashi, M.D., Ph.D., of Okayama University Graduate School of Medicine and Dentistry in Japan.

 

In the study, the researchers generated liver stem cells from mouse embryos to help power a liver assist device in mice with acute liver failure. Typically, mice with acute liver failure die within a matter of days. However, using the liver assist device containing mouse liver cells derived from embryonic stem cells, 90 percent of the mice in the study experienced long-term survival.

 

After implanting the liver assist device seeded with the embryo-derived cells, the new cells developed characteristics nearly identical to those of primary hepatocytes (liver cells). The new cells filtered the blood much as the liver does, and kept the mice alive, while mice not fitted with the liver device died within two days.

 

The study was one of two articles in Nature Biotechnology this week that describe making liver cells from mouse embryonic stem cells. A research team at Mount Sinai School of Medicine in New York City headed the second study.

 

A third article in Nature Biotechnology, written by a San Diego research team, described an efficient method for converting human embryonic stem cells into cells that produce hormones made by the pancreas, a technique that could lead to a cure for diabetes.

 

“Both (liver) articles lay out a road map for how to regenerate a failed liver using embryonic stem cells,” Dr. Fox said. “The next step is to apply this approach to producing human liver cells.

 

“Our study is an important first step, but there’s still plenty of work to be done. Our work, and the other studies published this week, show we’re getting closer and closer (to making this applicable to humans).”

 

Embryonic stem cells are the body’s master cells and have the ability to transform into any kind of cell or tissue in the body.

 

Drs. Fox and Kobayashi have worked together for years on liver cell regeneration. Dr. Kobayashi worked at UNMC for two years completing his post-doctoral training under Dr. Fox during the late 1990s. In 2005, two UNMC research teams – one headed by Dr. Fox, the other by Stephen Rennard, M.D., Larson Professor of Pulmonary Medicine – received training on how to use human embryonic stem cells in research. Both groups brought human embryonic stem cell lines back to Nebraska for their research. The embryonic stem cell lines are among the stem cell lines approved by President Bush.

 

A liver transplant surgeon, Dr. Fox is trying to determine if embryonic stem cells can be safely turned into liver cells that would ultimately be infused into failing livers. This form of therapy, cell transplantation, could be used as an alternative to organ transplantation for some patients with liver failure.

 

Due to the shortage of organ donors to meet the increased demand for organ transplants, Dr. Fox has, over the past decade, examined a variety of alternative ways – other than organ transplantation – to regenerate damaged livers. During this period, Dr. Fox has also studied the properties of adult stem cells and pig liver cells for this purpose.

 

Infusing human liver cells into a diseased liver in 1997, Dr. Fox was the first to get transplanted individual liver cells to partially correct a rare metabolic liver disease in a 10-year old child. In doing so, the patient was able to avoid undergoing a liver transplant for many years. The research was reported in the New England Journal of Medicine in May 1998.

 

Currently, more than 17,000 Americans are on the waiting list for a new liver. Liver failure can be caused by viruses such as hepatitis, by drug or alcohol damage and by a range of other diseases. Often the only cure is a transplant, and more than 5,000 liver transplants are done in the United States each year.

Bone Marrow Transplantation; A Success Story
 

Editorial in Middle East Health Magazine, Dec. 2006 by James O. Armitage, MD/University of Nebraska Medical Center, Omaha, NE, USA

 

It is very popular today to speak of stem cell research and the use of stem cells to treat disease.  However, many involved in the debate regarding research and clinical applications of stem cells might not appreciate that hematopoietic stem cells have been used therapeutically for half a decade.  Attempts to use hematopoietic stem cells to replace marrow aplastic anemia or to support intensive therapy of cancer began even more than 50 years ago.  However, it was not until more was understood about bone marrow functions and the nature of the hematopoietic stem cell before the procedure that we know today as hematopoietic stem cell transplantation became practical.  In the 1960’s successful allogeneic (i.e. from one individual to another) hematopoietic stem cell transplantation was reported for the treatment of leukemia and for the treatment of inherited immune defects.  Working at the University of Washington in Seattle Dr. Don Thomas (i.e. who won the Nobel Prize) and his colleagues worked out the techniques of hematopoietic stem cell transplantation to treat leukemia and aplastic anemia.  By the mid 1970s they reported 100 patients with acute leukemia treated with this approach with some patients surviving free of disease and apparently cured.

 

The presumed benefit of allogeneic hematopoietic stem cell transplantation was originally thought to be a consequence of the very intensive therapy administered before the infusion of hematopoietic stem cells.  It was known that unless a severely immunosuppressive treatment was applied, the patients own immune system would destroy the new hematopoietic stem cells.  Thus, high dose therapy was administered before the transplant in an attempt to allow engraftment and to eradicate the malignancy—i.e. usually leukemia.  Proof that immunosuppression was also required came from attempts to do hematopoietic stem cell transplantation in aplastic anemia.  It was originally felt that simply infusing hematopoietic stem cells should cure this disease since the marrow was “empty”.  However, it became apparent that in the absence of destruction of the patient’s residual immune cells, the new hematopoietic stem cells would be destroyed.  Thus, in patients with cancer, the very intensive therapy administered before infusion of the new hematopoietic stem cells was felt to be both curative of the cancer and engraftment.

 

In the late 1970’s and early 1980’s, it became apparent that the new hematopoietic stem cells and the new immune system that they produced in the patient might also have an anticancer effect.  The main complication of allogeneic hematopoietic stem cell transplantation is the development of a condition known as graft versus host disease.  In this illness, the new immune system produced by the infused, allogeneic hematopoietic stem cells can recognize the patient as “foreign” and carry out an immune attack on the patient’s organs.  Injury in this condition is especially frequently seen in the skin, liver, and gastrointestinal tract, and can some times be fatal.  In the late 1970s and early 1980s remission of relapsed leukemia was noted in patients who developed severe graft versus host disease.  It was speculated that there might be a graft versus leukemia effect and that it could be therapeutically important.  Careful studies of large numbers of patients demonstrated that patients who developed graft versus host, were less likely to have recurrent leukemia.  In fact, it appeared that much of the curative effect of allogeneic hematopoietic stem cell transplantation might be from the anticancer effect of the new immune system.

 

This observation led to attempts at reducing the intensity of the pretransplant therapy to reduce some of the risks of the procedure.  It is possible to use predominantly drugs that impair lymphocyte function with relatively minor toxic effects in the patient and avoid very high doses of other chemotherapeutic agents or total body radiotherapy.  It became apparent that sufficient impairment of the patient’s lymphocytes could allow the new hematopoietic stem cell graft to grow and eventually destroy the residual host lymphocytes giving a complete graft.  In some cancers that seem to be particularly sensitive to immunological attack, e.g. chronic myeloid leukemia and chronic lymphoid leukemia, the graft versus leukemia effect seems to be potentially curative and the reduced intensity treatment before the transplant appears to reduce transplant related mortality.  In those patients in whom the cancer does recur, reinfusing more of the donor’s lymphocytes often will reestablish remission.  This approach is sometimes termed reduced intensity allogeneic hematopoietic stem cell transplantation, or mini transplant is now undergoing intensive study in transplant centers throughout the world.

 

The idea that very high doses of anticancer therapy might be curative for some patients with cancer, and that the use of reinfusion of the patients own hematopoietic stem cells could avoid the dangers of graft versus host disease, led to clinical trials in what is called autologous hematopoietic stem cell transplantation.  In this treatment, hematopoietic stem cells have to be removed from the patient and stored until after the intensive cancer therapy is administered.  Since the patient’s own hematopoietic stem cells would be used to reestablish bone marrow function after the treatment, there would be no risk of graft versus host disease.  However, early problems with this treatment approach included occasional difficulties in collecting hematopoietic stem cells that were free of contamination by cancer cells and finding a way to store the hematopoietic stem cells for extended periods of time and keep them alive.  In allogeneic transplantation, the hematopoietic stem cells are taken from one individual and reinfused quickly into another.  However, since it takes time to administer the very intensive therapy, hematopoietic stem cells in autologous transplantation have to be cryopreserved for days to weeks before they are used.  Initial attempts at autologous hematopoietic stem cell transplantation involved repetitive bone marrow aspirations from the pelvis and sternum to collect sufficient cells.  It was not unusual for 200 aspirates to be required.  However, in the mid to late 1980s it became apparent that circulating hematopoietic stem cells could be collected using the process called aphersis where the blood is taken from the body, separated by centrifugation, and the desired cells collected with the rest of the blood reinfused into the patient.

 

Autologous hematopoietic stem cell transplantation tested the hypothesis that very intensive anticancer therapy could cure some patients when standard therapy failed.  Early studies in lymphoma showed that this can, in fact, be the case.  In patients whose recurrent or resistant lymphoma still can partially respond to standard doses or chemotherapy and achieve a minimal disease state, hematopoietic stem cell transplantation can often be curative.  As is the situation with allogeneic hematopoietic stem cell transplantation, treatment doesn’t benefit patients with all cancers, but is especially effective in patients with lymphoma, certain leukemias, multiple myeloma, and occasional other cancers.

 

Today both allogeneic and autologous hematopoietic stem cell transplantation are widely utilized to treat patients with cancer.  Many patients who would otherwise have died of their malignancy are now cured because of these procedures.  Allogeneic hematopoietic stem cell transplantation is also utilized for patients with aplastic anemia, inherited immune deficiency states, and certain other inherited disorders of blood production.  Both allogeneic and autologous hematopoietic stem cell transplantation are being studied in the treatment of patients with other life threatening immune diseases.  It is likely that both treatments will continue to be an important part of our therapeutic armentarium for years to come.

November 2006-Dr. McCashland to lead international transplant group

The International Liver Transplantation Society has elected UNMC associate professor Timothy McCashland, M.D., as its president.

 

Dr. McCashland was sworn in recently at the 2006 International Congress in Milan, Italy.

 

Throughout his one-year term, he will be responsible for representing the society, monitoring the strategic direction of the organization, serving as a voice for the membership and acting on the members’ behalf. As president, one of his key responsibilities will be to help shape the future agenda and direction of the society.

 

“Volunteer leadership is a critical component to the success of any association, and ILTS is fortunate to have such a dedicated individual leading the society,” said Diann Stern, ILTS executive director. “We are confident Tim’s leadership and expertise will be an asset to ILTS and help ensure continued growth and success for the association moving forward.”

 

Dr. McCashland said it is an honor and privilege to serve the society.

 

“Its unique ability to bring to together leaders in the field of transplantation … is exciting,” Dr. McCashland said. “We look to expand our role in providing educational opportunities for physicians in training and to be an informational resource for patients and families concerning liver transplantation.”

 

Dr. McCashland earned his medical degree from UNMC in 1987 and completed his internal medicine residency at UNMC in 1990. He served a fellowship in gastroenterology at UNMC before completing a fellowship in therapeutic endoscopy at Western General Hospital in Edinburgh, Scotland, in 1993. Dr. McCashland is board-certified in internal medicine and gastroenterology.

 

ILTS is an international organization dedicated to the advancement of the science and practice of liver transplantation. Since its inception in 1990, the goal of the society has been to raise the standard of care for patients requiring liver transplantation and to promote education and research by disseminating and exchanging information related to liver transplantation within the medical community, as well the public.
