Effects of supervised exercise on progression-free survival in lymphoma patients: an exploratory follow-up of the HELP Trial.

Purpose: Few randomized controlled trials in exercise oncology have examined survival outcomes. Here, we report an exploratory follow-up of progression-free survival (PFS) from the Healthy Exercise for Lymphoma Patients (HELP) Trial.

Methods: The HELP Trial randomized 122 lymphoma patients between 2005 and 2008 to either control (n = 62) or 12 weeks of supervised aerobic exercise (n = 60).

Associations between exercise and posttraumatic growth in gynecologic cancer survivors.

Purpose: Exercise improves numerous psychosocial outcomes in cancer survivors; however, few studies have examined posttraumatic growth. The primary objective of this study was to examine the association between exercise and posttraumatic growth in gynecologic cancer survivors (GCS).

Methods: Using the Alberta Cancer Registry, a random sample of endometrial, ovarian, and cervical cancer survivors were mailed a self-report survey that assessed demographic and medical variables, aerobic and strength exercise, and posttraumatic growth using the posttraumatic growth inventory, impact of cancer scale, and benefit finding scale.

Effects of exercise dose and type on sleep quality in breast cancer patients receiving chemotherapy: a multicenter randomized trial.

To examine the effects of different doses and types of exercise on sleep quality in breast cancer patients receiving chemotherapy. A multicenter trial in Canada randomized 301 breast cancer patients between 2008 and 2011 to thrice weekly, supervised exercise during chemotherapy consisting of either a standard dose of 25-30 min of aerobic exercise (STAN; n = 96), a higher dose of 50-60 min of aerobic exercise (HIGH; n = 101), or a combined dose of 50-60 min of aerobic and resistance exercise (COMB; n = 104). The secondary sleep outcomes in the trial were assessed by the Pittsburgh Sleep Quality Index (PSQI) at baseline, twice during chemotherapy, and postchemotherapy.

A comparison of physical activity correlates across breast, prostate and colorectal cancer survivors in Nova Scotia, Canada.

Purpose: The purpose of this study was to compare the medical, demographic and social cognitive correlates of physical activity (PA) in breast (BCS), prostate (PCS) and colorectal (CRCS) cancer survivors.

Methods: A stratified random sample of 2062 BC, PC and CRC survivors diagnosed between 2003 and 2011 was identified by the Nova Scotia Cancer Registry (NSCR) and mailed a questionnaire assessing PA, social-cognitive constructs from the theory of planned behaviour (TPB), and demographic and medical variables. Structural equation modelling was used to conduct path analyses of the TPB within each cancer survivor group and an invariance analysis was used to compare the TPB across groups.

Sport participation in colorectal cancer survivors: an unexplored approach to promoting physical activity.

Purpose: Physical activity improves health outcomes in colorectal cancer (CRC) survivors, but participation rates are low. One understudied strategy for increasing physical activity in CRC survivors may be sport participation. Here, we report the sport participation rate, sport preferences, and correlates of sport participation among CRC survivors.

Feasibility and preliminary efficacy of progressive resistance exercise training in lung cancer survivors.

Lung cancer survivors exhibit poor functional capacity, physical functioning, and quality of life (QoL). Here, we report the feasibility and preliminary efficacy of a progressive resistance exercise training (PRET) intervention in post-treatment lung cancer survivors. Seventeen post-treatment lung cancer survivors (10 female), with a mean age of 67 (range 50-85), mean BMI of 25, and diagnosed with non-small cell lung cancer (94%) were recruited in Edmonton, Canada between August 2009 and August 2010 to undergo PRET.

Physical activity and cancer: an introduction.

Physical activity (PA) is an important health behavior for many diseases, but its role in cancer control has been understudied and underappreciated. In this chapter, we introduce this volume on PA and cancer and provide an overview of its content and organization. We also review some of the methodological challenges in this field, summarize the key conclusions of each chapter, and offer some general directions for future research.

Physical activity and health-related quality of life in young adult cancer survivors: a Canadian provincial survey.

Objectives: Physical activity (PA) improves health-related quality of life (HRQL) in several cancer survivor groups but no studies have focused on young adult cancer survivors (YACS). This study determined the prevalence of PA in YACS and examined dose-response associations with HRQL.

Methods: A random sample of 2,000 YACS between the ages of 20-44 were identified through a Canadian provincial cancer registry and mailed a survey that included the Leisure-Time Exercise Questionnaire, the Medical Outcomes Study 36-Item Short Form (SF36) survey, and several validated psychosocial scales.

Association between neighborhood socioeconomic status and screen time among pre-school children: a cross-sectional study.

Background: Sedentary behavior is considered a separate construct from physical activity and engaging in sedentary behaviors results in health effects independent of physical activity levels. A major source of sedentary behavior in children is time spent viewing TV or movies, playing video games, and using computers. To date no study has examined the impact of neighborhood socioeconomic status (SES) on pre-school children's screen time behavior.

Moderator effects in a randomized controlled trial of exercise training in lymphoma patients.

Background: The Healthy Exercise for Lymphoma Patients trial showed that aerobic exercise training improved important health outcomes in lymphoma patients. Here, we examine potential moderators of the exercise training response.

Methods: Lymphoma patients were stratified by major disease type and current treatment status and randomly assigned to usual care (n = 62) or aerobic exercise training (n = 60) for 12 weeks.

Randomized controlled trial of the effects of aerobic exercise on physical functioning and quality of life in lymphoma patients.

Purpose: Lymphoma patients commonly experience declines in physical functioning and quality of life (QoL) that may be reversed with exercise training.

Patients And Methods: We conducted a randomized controlled trial in Edmonton, Alberta, Canada, between 2005 and 2008 that stratified 122 lymphoma patients by major disease type and current treatment status and randomly assigned them to usual care (UC; n = 62) or 12 weeks of supervised aerobic exercise training (AET; n = 60). Our primary end point was patient-rated physical functioning assessed by the Trial Outcome Index-Anemia.

Associations between exercise, quality of life, and fatigue in colorectal cancer survivors.

Purpose: This study was designed to examine quality of life and fatigue in colorectal cancer survivors meeting and not meeting public health exercise guidelines.

Methods: A Canadian provincial cancer registry identified colorectal cancer survivors who were mailed a questionnaire that assessed self-reported exercise, quality of life (Functional Assessment of Cancer Therapy - Colorectal), fatigue, medical, and demographic variables.

Results: Completed questionnaires were received from 413 (61.

Predictors of follow-up exercise behavior 6 months after a randomized trial of exercise training during breast cancer chemotherapy.

Purpose: Exercise during breast cancer chemotherapy is beneficial but it needs to be maintained into survivorship to optimize long-term benefits. Here, we report the predictors of follow-up exercise behavior 6 months after a randomized exercise trial in breast cancer patients.

Methods: Breast cancer patients (N = 242) initiating adjuvant chemotherapy were randomly assigned to usual care (n = 82), supervised resistance exercise (n = 82), or supervised aerobic exercise (n = 78) for the duration of their chemotherapy.

Barriers to supervised exercise training in a randomized controlled trial of breast cancer patients receiving chemotherapy.

Background: Exercise adherence is a challenge for breast cancer patients receiving chemotherapy but few studies have identified the key barriers.

Purpose: In this paper, we report the barriers to supervised exercise in breast cancer patients participating in a randomized controlled trial.

Methods: Breast cancer patients initiating adjuvant chemotherapy (N = 242) were randomly assigned to usual care (n = 82) or supervised resistance (n = 82) or aerobic (n = 78) exercise.

Exercise, aging, and cancer.

Cancer is a common disease that affects over 150 000 Canadians every year. About 78% of all cancers are diagnosed in adults aged 60 years and older. Improved survival rates for cancer survivors have brought lifestyle and quality of life issues to the forefront.

Physical activity and cancer control.

Objectives: To provide an overview and update of physical activity (PA) research across the entire cancer control continuum.

Data Sources: Previous cancer control frameworks and selected PA and cancer research that has been published over the past 5 years.

Conclusion: There have been major scientific advances in PA research across many, but not all, of the cancer control categories over the past 5 years.

Medical, demographic, and psychosocial correlates of exercise in colorectal cancer survivors: an application of self-determination theory.

Objectives: The purpose of the present study was to evaluate medical, demographic, and psychosocial correlates of exercise in colorectal cancer survivors (CRC-S) using self-determination theory (SDT).

Methods: Participants were 414 CRC-S who completed a mailed survey that assessed self-reported exercise, medical and demographic variables, and SDT constructs consisting of behavioral regulation for exercise, psychological needs satisfaction in exercise (PNSE), and perceived autonomy support (PAS).

Results: CRC-S with less education were significantly less likely to meet exercise guidelines (21 vs 31%; p < 0.

Associations between exercise and quality of life in bladder cancer survivors: a population-based study.

Background: Exercise has been shown to improve quality of life (QoL) in some cancer survivor groups, but it is unknown if the unique QoL issues faced by bladder cancer survivors are also amenable to an exercise intervention. This study provides the first data examining the association between exercise and QoL in bladder cancer survivors.

Methods: Bladder cancer survivors identified through a provincial cancer registry were mailed a survey that included the Godin Leisure Time Exercise Questionnaire, the Functional Assessment of Cancer Therapy-Bladder (FACT-Bl) scale, and the Fatigue Symptom Inventory.
