The impact of supervised exercise intervention on short-term postprogram leisure time physical activity level in cancer patients undergoing chemotherapy: 1- and 3-month follow-up on the body & cancer project.

BACKGROUND: Exercise is becoming an important component of cancer rehabilitation programs. A consistent finding across studies is that patients experience improved physical fitness and reduced fatigue. However, sustained physical activity is essential if the benefits are to be preserved over the course of cancer survivorship. OBJECTIVE: This study examined self-reported short-term exercise adherence following a 6-week, supervised exercise program (muscle strength, cardiovascular fitness, relaxation, body awareness, and massage) in a heterogeneous group of 61 cancer patients (mean age 42.9 years, 82% oncological and 18% haematological) from the Body & Cancer Project. METHODS: Semistructured interviews were used to quantitatively assess leisure time physical activity level 1 and 3 months after completion of the program. The study furthermore included 3-month follow-up assessment of psychological distress (Hospital Anxiety and Depression Scale-HADS). Patient statements were selected that best illustrated trends found in the statistical material. RESULTS: There was a significant postprogram reduction in physical activity from 6 to 10 weeks and from 6 to 18 weeks. However, the patients (half of whom were still undergoing treatment at the time of follow-up) reported a higher physical activity level postprogram compared to their baseline levels. The analyses showed a positive association between the 3-month postprogram physical activity level and pre-illness physical activity level, treatment, and postprogram changes in depression. SIGNIFICANCE OF RESEARCH: Given the significant decrease in postprogram PA level, especially in subjects still undergoing cancer treatment, the study suggests that continuous supervised programs may be required in order to encourage and support exercise adherence in this population. However, randomized clinical controlled trials and more follow-up studies are needed to establish the optimal program length and content for sustained exercise adherence in cancer patients.

The effect of a multidimensional exercise intervention on physical capacity, well-being and quality of life in cancer patients undergoing chemotherapy.

The aim of the present study was to investigate the impact of a multidimensional exercise intervention focusing on physical capacity; one-repetition maximum (1RM) and maximum oxygen uptake (VO2Max), activity level, general well-being and quality of life in cancer patients undergoing chemotherapy. The intervention comprised resistance and fitness training, massage, relaxation and body-awareness training. Eighty-two cancer patients, with or without evidence of residual disease, were included: 66 patients with 13 different types of solid tumours and 16 patients with 6 types of haematological malignancies. The patients trained in mixed groups for 9 h weekly for 6 weeks. Physical capacity, physical activity level and psychosocial well-being as measured by the Medical Outcomes Study 36-item Short-Form Health Survey and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 were assessed pre- and post-intervention. Highly significant increases were achieved in muscular strength (p<0.001), physical fitness (p<0.001) and physical activity levels (p<0.001). The patients reported significant reduction in treatment-related symptoms, i.e., fatigue (p=0.006) and pain (p=0.03). Highly significant improvements were observed in physical functioning (p<0.001) and role functioning (p<0.001). Even patients with advanced disease were able to improve their results after 6 weeks. It is concluded that a multidimensional exercise intervention, including resistance training, may be beneficial for cancer patients undergoing chemotherapy. This study indicates significant clinical meaningful improvements. The exact role of the intervention has to be defined in a randomized controlled design. A clinically controlled trial including 250 patients is currently being carried out.

The impact of a multidimensional exercise program on self-reported anxiety and depression in cancer patients undergoing chemotherapy: a phase II study.

Little is known about the role of exercise in improving cancer patients' mood while undergoing chemotherapy. In this phase II study changes in self-reported anxiety and depression and fitness (VO2max) are reported in relation to a 6-week, 9 h weekly, multidimensional exercise program. A total of 91 patients receiving chemotherapy, between 18 and 65 years old, completed a Hospital Anxiety and Depression Scale Questionnaire (HADS; response rate 91%, adherence rate 78%). Anxiety (p < 0.001) and depression (p = 0.042) was significantly reduced. The mean +/- SD of the change was -1.14 +/- 2.91 for anxiety and -0.44 +/- 2.77 for depression. Improvements in fitness were correlated with improvements in depression, chi2(1) = 3.966, p = 0.046, but not with improvements in anxiety, chi2(1) = 0.540, p = 0.462. The research suggests that exercise intervention may have a beneficial impact on psychological distress for cancer patients receiving chemotherapy with low to moderate levels of baseline psychomorbidity. The study furthermore indicates that changes in distress may be associated with disease status and levels of physical activity undertaken during disease. The study is followed up by an ongoing randomized clinical controlled trial to evaluate potential causal effects of exercise intervention on psychological distress and fitness in cancer patients undergoing chemotherapy.
