Little is known about the physical activity (PA) of young adults (YAs) during cancer therapy. In this feasibility study, 14 YAs (20-34 years old) completed a six-minute walk test, recorded their steps per day for one week, and answered weekly self-reports about physical activity, fatigue, sleep-wake disturbances, and depression during one cycle of chemotherapy. Findings suggest YAs are willing to complete a PA study during chemotherapy and have variable sleep and activity schedules. Their symptoms varied in severity, with highest scores for fatigue. Studies to improve PA in YAs during chemotherapy are warranted to manage short-and long-term treatment effects.Keywords: cancer care continuum, chemotherapy, exercise, physical activity, supportive care P hysical activity (PA) during treatment for cancer is an evidence-based intervention recommended to relieve disease-and treatment-related symptoms such as fatigue and sleep disturbances.1-3 Maintaining PA during cancer treatment may also mitigate the long-term negative effects of inactivity, such as deconditioning and weight gain, that often occur during and after the cancer treatment period.4,5 Staying physically active may also promote better disease outcomes for patients at high risk for developing second cancers.6 Many young adults (YAs) with cancer, however, become sedentary during their months of chemotherapy due to common physical and psychosocial symptoms, such as fatigue and depressed mood. Frequent clinic and hospital visits disrupt daily activity and sleep routines, making it difficult to maintain previously established habits and schedules.PA research to date has focused mainly on outcomes in adults with common cancers, especially following the completion of therapy, and little is known about PA in YAs with cancer. Emerging evidence suggests that adolescent cancer survivors experience significant declines in PA during treatment that may last past completion of treatment. [7][8][9] Studies are needed to describe PA in YAs during active treatment and to test PA interventions for YAs receiving chemotherapy.The aims of this study were to: (1) test the feasibility of procedures to measure four symptoms (fatigue, sleep disturbance, wake disturbance, and emotional disturbancedepression) and PA in YAs; and (2) gather feasibility data related to functional status, symptom severity, and PA over the course of one cycle of chemotherapy. These data will inform the design of a trial to test an age-specific intervention to improve symptom management, PA, and quality of life outcomes for YAs who may become long-term cancer survivors.
MethodsData collection began on the first day of a chemotherapy cycle and lasted 2 weeks. This feasibility study was conducted at the University of Virginia Medical Center between November 2010 and May 2012.
ParticipantsInclusion criteria included patients who: (1) were diagnosed with any cancer between the ages of 18 and 39; (2) were receiving chemotherapy on a cycle every 3-4 weeks; (3) were in their first through sixth month of chemothera...
