TL;DR: It was concluded that physical exercise may be related to QOL in BMT patients, but that experimental research is needed before any definitive conclusions can be drawn.
Abstract: Preliminary evidence indicates that physical exercise may be an effective strategy for the rehabilitation of cancer patients following high dose chemotherapy (HDC) and bone marrow transplantation (BMT), but the focus of this research has been on physical fitness and medical outcomes. In the present study, we employed a prospective design to examine the relationship between physical exercise and various quality of life (QOL) indices in 25 BMT patients. Participants completed weekly self-administered questionnaires upon being admitted to hospital, and monitored the frequency and duration of their exercise during hospitalization. Statistical analyses indicated that exercise during hospitalization was significantly correlated with almost all QOL indices, including physical well-being, psychological well-being, depression, anxiety and days hospitalized. Moreover, only some of the correlations were attenuated after controlling for relevant demographic and medical variables. It was concluded that physical exercise may be related to QOL in BMT patients, but that experimental research is needed before any definitive conclusions can be drawn.

TL;DR: A comprehensive review of the recent literature reveals that exercise has a positive effect on a broad range of quality of life parameters after patients are diagnosed as having cancer.
Abstract: A comprehensive review of the recent literature reveals that exercise has a positive effect on a broad range of quality-of-life parameters after patients are diagnosed as having cancer. The general exercise prescription is moderate-intensity exercise, 3 to 5 days per week, 20 to 30 minutes per session. Conditions that warrant prescription modification include fatigue periods during treatment, acute or chronic physical impairments that may have resulted from surgery or adjuvant therapy, and the presence of bone cancer. Research suggests that physicians who prescribe exercise improve motivation and adherence in their patients who have cancer.

TL;DR: In this paper, the authors examined a model of exercise behavior change that integrated the theory of planned behavior (TPB) with the processes and stages of change from the transtheoretical model and concluded that the proposed integrated model produced important theoretical insights into how and why people successfully change their exercise behavior.

TL;DR: It is concluded that the theory of planned behavior provided an excellent understanding of exercise intentions in this population and context and that its ability to predict exercise behavior could be improved substantially by taking into account significant medical complications.
Abstract: Preliminary evidence indicates that physical exercise may be an effective strategy for the rehabilitation of cancer patients following bone marrow transplantation (BMT), but the determinants of such exercise are not known. In this study, we used a prospective design to evaluate the theory of planned behavior (Ajzen, 1991) as a social cognitive framework for understanding exercise motivation and behavior in 37 BMT patients. On admittance to the hospital, participants completed a baseline questionnaire that assessed the theory of planned behavior and then monitored the frequency and duration of self-initiated cycle ergometer exercise during their hospitalization. Hierarchical regression analyses demonstrated that intention and perceived behavioral control explained 36% of the variance in exercise behavior when the analyses were restricted to nonthrombocytopenic patients (n = 28). Moreover, attitude and perceived behavioral control explained 68% of the variance in exercise intentions. We concluded that the theory of planned behavior provided an excellent understanding of exercise intentions in this population and context and that its ability to predict exercise behavior could be improved substantially by taking into account significant medical complications.

TL;DR: It is concluded that personality, particularly neuroticism, is strongly related to subjective well-being in patients with colorectal cancer and that clinicians should be aware of its implications for patients' functioning.
Abstract: The present study examined the relationship between a general personality framework (the five-factor model) and subjective well-being in patients with colorectal cancer. Participants were 56 post-surgical patients with colorectal cancer who completed a mailed, self-administered questionnaire that assessed demographic characteristics, personality, and subjective well-being (life satisfaction, positive affect, negative affect, and affect balance). Pearson correlations indicated that neuroticism had the highest correlation with life satisfaction (r= -.61), affect balance (r= -.61), and negative affect (r= .48), whereas extroversion had the highest correlation with positive affect (r= .57). Moreover, hierarchical multiple regression analyses indicated that personality explained an additional 20% to 29% of the variance in subjective well-being after important demographic and medical variables were controlled for. The authors concluded that personality, particularly neuroticism, is strongly related to ...
