Effect of a multimodal high intensity exercise intervention in cancer patients undergoing chemotherapy: randomised controlled trial

Objective To assess the effect of a multimodal group exercise intervention, as an adjunct to conventional care, on fatigue, physical capacity, general wellbeing, physical activity, and quality of life in patients with cancer who were undergoing adjuvant chemotherapy or treatment for advanced disease. Design Randomised controlled trial. Setting Two university hospitals in Copenhagen, Denmark. Participants 269 patients with cancer; 73 men, 196 women, mean age 47 years (range 20-65) representing 21 diagnoses. Main exclusion criteria were brain or bone metastases. 235 patients completed follow-up. Intervention Supervised exercise comprising high intensity cardiovascular and resistance training, relaxation and body awareness training, massage, nine hours weekly for six weeks in addition to conventional care, compared with conventional care. Main outcome measures European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), Medical Outcomes Study Short Form (MOS SF-36), Leisure Time Physical Activity Questionnaire, muscular strength (one repetition maximum), maximum oxygen consumption (Vo2max). Statistical methods The general linear model was used for continuous outcome while analysis of associates between categorical outcomes was performed as analysis of marginal homogeneity in contingency tables. Results Adjusted for baseline score, disease, and demographic covariates, the intervention group showed an estimated improvement at six weeks for the primary outcome, fatigue, of −6.6 points (95% confidence interval −12.3 to −0.9, P=0.02; effect size=0.33, 0.04 to 0.61). Significant effects were seen on vitality (effect size 0.55, 95% CI 0.27 to 0.82), physical functioning (0.37, 0.09 to 0.65), role physical (0.37, 0.10 to 0.64), role emotional (0.32, 0.05 to 0.59), and mental health (0.28, 0.02 to 0.56) scores. Improvement was noted in physical capacity: estimated mean difference between groups for maximum oxygen consumption was 0.16 l/min (95% CI 0.1 to 0.2, P<0.0001) and for muscular strength (leg press) was 29.7 kg (23.4 to 34.9, P<0.0001). No significant effect was seen on global health status/quality of life. Conclusion A supervised multimodal exercise intervention including high and low intensity components was feasible and could safely be used in patients with various cancers who were receiving adjuvant chemotherapy or treatment for advanced disease. The intervention reduced fatigue and improved vitality, aerobic capacity, muscular strength, and physical and functional activity, and emotional wellbeing, but not quality of life.

High‐intensity resistance and cardiovascular training improve physical capacity in cancer patients undergoing chemotherapy

The purpose of the study was to examine the effects of a supervised high‐ and low‐intensity structured training program in cancer patients concurrently undergoing chemotherapy. Seventy patients, in different stages of the disease and with different diagnoses (48 females, 22 males), between 18 and 65 years of age (mean age 42.8) participated in a 9‐h weekly training program over 6 weeks. The intervention involved physical exercise, relaxation, massage, and body‐awareness training. Physical capacity (one‐repetition maximum tests (1RM), VO2max) and body composition (weight, skin‐fold) were compared before and after the exercise intervention.

Efficacy of multimodal exercise-based rehabilitation on physical activity, cardiorespiratory fitness, and patient-reported outcomes in cancer survivors: a randomized, controlled trial

BACKGROUND Sedentary behavior and impaired cardiovascular reserve capacity are common late effects of cancer therapy emphasizing the need for effective strategies to increase physical activity (PA) in cancer survivors. We examined the efficacy of a 12-month exercise-based rehabilitation program on self-reported PA, cardiorespiratory fitness (VO2peak), strength, and patient-reported outcomes. PATIENTS AND METHODS Two hundred fourteen post-treatment cancer survivors were randomly assigned to a 12-month rehabilitation program consisting of individual (x3) and group-based (x6) counseling in combination with once weekly high-intensity group-based exercise training (the Copenhagen Physical Activity after Cancer Treatment, PACT; n = 108) or to a health evaluation program (HE, n = 106). Study outcomes were assessed at baseline, 6 months, and 12 months. RESULTS After 12 months, the percentage of patients reporting meeting PA goal behavior (≥3 h/week) was significantly increased in the PACT group versus the HE group (70.4% versus 43.4%, P = 0.001). Repeated measures analyses indicated a statistically significant improvement in VO2peak (l min(-1)) in favour of PACT (treatment effect ratio = 1.04; 95% confidence interval 1.00-1.07; P = 0.032). Significant between group differences were also observed for strength (P < 0.001), depression (P = 0.020) and mental health (P = 0.040). CONCLUSION A 12-month exercise-based rehabilitation program is an effective strategy to promote PA and improve VO2peak in cancer survivors.

Football training improves lean body mass in men with prostate cancer undergoing androgen deprivation therapy

Androgen deprivation therapy (ADT) remains a cornerstone in the management of patients with prostate cancer (PCa) despite adverse effects on body composition and functional parameters. We compared the effects of football training with standard care in PCa patients managed with ADT (> 6 months). Fifty‐seven men aged 67 (range: 43–74) were randomly assigned to a football group (FG, n = 29) or a usual care control group (CON, n = 28). The primary outcome was change in lean body mass (LBM) assessed by dual‐energy X‐ray absorptiometry scanning. Secondary outcomes included changes in knee‐extensor muscle strength (one repetition maximum), fat percentage, and maximal oxygen uptake (VO2max). Mean heart rate during training was 137.7 (standard deviation 13.7) bpm or 84.6 (3.9)% HRmax. In FG, LBM increased by 0.5 kg [95% confidence interval (CI) 0.1–0.9; P = 0.02] with no change in CON (mean group difference 0.7 kg; 95% CI 0.1–1.2; P = 0.02). Also, muscle strength increased in FG (8.9 kg; 95% CI 6.0–11.8; P < 0.001) with no change in CON (mean group difference 6.7 kg; 95% CI 2.8–10.7; P < 0.001). In FG, VO2max increased (1.0 mL/kg/min; 95% CI 0.2–1.9; P = 0.02) and fat percentage tended to decrease (0.7%; 95%CI 1.3–0.0; P = 0.06), but these changes were not significantly different from CON. In conclusion, football training over 12 weeks improved LBM and muscle strength compared with usual care in men with prostate cancer receiving ADT.

Self-reported physical activity behaviour; exercise motivation and information among Danish adult cancer patients undergoing chemotherapy

BACKGROUND Physical activity is considered an important and determining factor for the cancer patients physical well-being and quality of life. However, cancer treatment may disrupt the practice of physical activity, and the prevention of sedentary lifestyles in cancer survivors is imperative. PURPOSE The current study aimed at investigating self-reported physical activity behaviour, exercise motivation and information in cancer patients undergoing chemotherapy. METHODS AND SAMPLE Using a cross-sectional design, 451 patients (18-65 years) completed a questionnaire assessing pre-illness and present physical activity; motivation and information received. RESULTS Patients reported a significant decline in physical activity from pre-illness to the time in active treatment (p<0.001). Amongst the respondents, 68% answered that they believed exercise to be beneficial; and 78% claimed not exercising as much as desired. Exercise barriers included fatigue (74%) and physical discomfort (45%). Present physical activity behaviour was associated with pre-illness physical activity behaviour (p<0.001), exercise belief (p<0.001), and diagnosis (p<0.001). More patients <40 years than patients >40 years (OR 0.36, p<0.001); more men than women (OR 2.12, p<0.001); and more oncological than haematological patients (OR 0.41, p<0.001) stated being informed about physical activity. Moreover patients who claimed to have been informed about exercise were more in agreement with being able to exercise while undergoing chemotherapy (OR 1.69, p=0.023). CONCLUSIONS This study suggests that Danish adult cancer patients in chemotherapy experience a significant decline in physical activity behaviour. Results indicate a general positive interest in physical activity amongst the patients, which however may be only suboptimally exploited.

Revisiting Symbolic Interactionism as a Theoretical Framework Beyond the Grounded Theory Tradition

The tight bond between grounded theory (GT) and symbolic interactionism (SI) is well known within the qualitative health research field. We aimed to disentangle this connection through critical reflection on the conditions under which it might add value as an underpinning to studies outside the GT tradition. Drawing on an examination of the central tenets of SI, we illustrate with a field study using interpretive description as methodology how SI can be applied as a theoretical lens through which layers of socially constructed meaning can help surface the subjective world of patients. We demonstrate how SI can function as a powerful framework for human health behavior research through its capacity to orient questions, inform design options, and refine analytic directions. We conclude that using SI as a lens can serve as a translation mechanism in our quest to interpret the subjective world underlying patients’ health and illness behavior.

Struggling with cancer and treatment: young athletes recapture body control and identity through exercise: qualitative findings from a supervised group exercise program in cancer patients of mixed gender undergoing chemotherapy

Cancer and treatment can negatively affect the bodys performance and appearance. Exercise has been tested in a few studies for altered body image among middle‐aged women with breast cancer. The aim of the study was to explore how young pre‐cancer athletes of both genders experience disease‐ and treatment‐related physical fitness and appearance changes while undergoing chemotherapy and participating in a 6‐week group exercise intervention. A prospective, explorative study using semi‐structured interviews was conducted before and at termination of the intervention. The study included 22 cancer patients (median age 28 years). The young athletes experienced a change from a high level of physical activity, body satisfaction and a positive self‐identity to a low level of physical activity, body denial and a negative self‐identity. In the program, the patients experienced increased physical strength and recapture of certain aspects of their former positive body perception. Deterioation of muscle functions caused by chemotherapy was particularly painful to these patients, independent of gender and age. Young physically active patients are heavily dependent on their physical capacity, body satisfaction and self‐identity. This should be taken into account when designing programs to rehabilitate and encourage these patients through the often‐strenuous antineoplastic treatments.

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.

Physical activity maintenance in patients with rheumatoid arthritis: a qualitative study

Objective: To describe the experience of physical activity maintenance in patients with rheumatoid arthritis. Design: A qualitative salutogenic-oriented interview study. Setting: A rheumatology outpatient clinic. Subjects: A purposive sample of 16 physically active patients (mean age 50, range 37–67) diagnosed with rheumatoid arthritis on average 21 years previously (range 4–46 years). Methods: In-depth interviews were conducted using a semi-structured interview guide to illuminate how the phenomenon ‘physical activity maintenance’ was experienced by patients with rheumatoid arthritis. The interviews were analysed using systematic text condensation, inspired by Giorgi’s descriptive phenomenological methodology. Results: The analysis revealed three categories: (1) knowing and enjoying the body; (2) responsibility and challenges; (3) autonomy and social belonging. On the basis of these categories, the essential meaning of the phenomenon of physical activity maintenance for patients with rheumatoid arthritis was summarized into ‘striving for a transparent body and participation’, pointing to experiences of sensations of wellbeing, liberation from restrictions and social participation on equal terms with non-arthritis populations. Conclusion: This study demonstrates that physical activity in patients with rheumatoid arthritis may be understood as a resource to resist disability and to feel and stay healthy while creating and sustaining meaningfulness in life.

Exercise may reduce depression but not anxiety in self-referred cancer patients undergoing chemotherapy. Post-hoc analysis of data from the ‘Body & Cancer’ trial

Abstract Background. The diagnosis and treatment of cancer may cause clinically significant and persistent psychological morbidity. The objective of this study was to determine the short-term effect of a six week exercise intervention on anxiety and depression in cancer patients undergoing chemotherapy (The ‘Body & Cancer’ trial). Methods. Two hundred and nine self-referred patients (52 males, 157 females, mean age 47 years) were randomised into an intervention group and a waiting-list control group. Anxiety and depression was measured by the Hospital Anxiety and Depression Scale. Results. At baseline, 23.5% and 11.5% of the population scored >8 on the HADS and were classified as suspicious or definite cases of anxiety and depression, respectively. Adjusted for baseline score, disease and demographic covariates the estimated intervention effect showed improvement at six weeks for depression of −0.7 points (95% confidence interval [CI] −1.27 to −0.14, p = 0.0153). No significant effect was seen on anxiety. Further subanalysis, including only suspicious or definite cases of depression, resulted in an estimated intervention effect of −2.53 points (95% CI, −0.64 to −0.42, p = 0.021). Conclusion. Anti-depressant effects could be caused by exercise in self-referred cancer patients undergoing chemotherapy. Dedicated trials and follow-up studies are needed to clarify the optimal duration and content of exercise interventions to meet the needs of clinically depressive or anxious patients.
