"Fatigue in Breast Cancer – A Behavioral Sleep Intervention" compares immediate and consequent fatigue between the two groups. The study examines stage I, II or IIIA breast cancer patients, age 19 and older, postoperative, during four or eight cycles of adjuvant chemotherapy. The women were randomly assigned to the interventional (sleeping) or attentional (eating) group.
Cancer-related fatigue (CRF) has a rippling effect on a patient's life — with significant physical, emotional, social and economic consequences that may persist for months or years after completing treatment, Dr. Berger said. Unsatisfactory sleep is a companion to fatigue and further debilitates waking hours.
"When you add fatigue into the model, you also get more pain, anxiety, depression, lower activity rates, poor appetite and sleep interruption," Dr. Berger said. Little is known about the relationship between fatigue and insomnia in breast cancer patients, and the study hopes to shine light on the association.
Women in the attentional control group are instructed in healthy eating habits. The interventional group meets with a nurse educator to learn the four components of behavioral sleep intervention. First is sleep restriction. Group members are told to limit nighttime sleep to the amount they normally get. They can add one additional hour if they feel ill. If they need a 30 to 40-minute nap during the day, the nap is to be completed at least four hours before bedtime. There should be no long naps.
