Objective To explore physically inactive breast and colon cancer patients’ prediagnosis exercise history and attitudes to physical activity (PA) and experiences in initiating PA while undergoing adjuvant chemotherapy. Design An explorative qualitative study guided the interpretive analysis of semistructured, open-ended interviews conducted at initiation of chemotherapy and after 12 weeks. The study was embedded in a pilot randomised controlled trial. Setting Participants were recruited from the Oncological Department at a hospital in Copenhagen, Denmark. Participants 33 patients with cancer, median age 49 years: 25 patients with breast cancer and 8 with colon cancer, 72% with a low cardiac respiratory fitness level and the majority with a high level of education. Patients received adjuvant chemotherapy, oncologist’s PA recommendation and exercise, cancer nurse specialist’s counselling prior to allocation to PA interventions or waitlist control group. Results Prediagnosis exercise had been excluded from patients’ daily lives due to perceptions of exercise as boring, lack of discipline and stressful work conditions for both genders. Recommendations from oncologists and nurses inspired the patients to reconsider their attitudes and behaviour by accepting recruitment and participation in PA interventions during chemotherapy. Despite extensive side effects, most patients adhered to their PA commitment due to their perception of the bodily, emotional and social benefits and support of healthcare professionals, peers and family. Conclusion The patients’ attitude towards exercise transformed from having no priority in patients’ daily lives prediagnosis to being highly prioritised. This study identified four important phases in the exercise transformation process during the patients’ treatment trajectory of relevance to clinicians in identifying, motivating and supporting physically inactive patients with cancer at long-term risk. Clinicians should address young, highly educated patients with cancer at onset of adjuvant chemotherapy due to their specific risk of a sedentary lifestyle resulting from being in stressful, ambitious careers.

In an effort to reduce the risk of breast cancer-related arm lymphedema, patients are commonly advised to avoid heavy lifting, impacting activities of daily living and resistance exercise prescription. This advice lacks evidence, with no prospective studies investigating arm volume changes after resistance exercise with heavy loads in this population. The purpose of this study is to determine acute changes in arm volume after a session of low- and heavy-load resistance exercise among women undergoing adjuvant chemotherapy for breast cancer at risk for arm lymphedema. This is a randomized cross-over trial. Participants: Women receiving adjuvant chemotherapy for breast cancer who have undergone axillary lymph node dissection will be recruited from rehabilitation centers in the Copenhagen area. Intervention: Participants will be randomly assigned to engage in a low- (two sets of 15–20 repetition maximum) and heavy-load (three sets of 5–8 repetition maximum) upper-extremity resistance exercise session with a one week wash-out period between sessions. Outcome: Changes in extracellular fluid (L-Dex score) and arm volume (ml) will be assessed using bioimpedance spectroscopy and dual-energy x-ray absorptiometry, respectively. Symptom severity related to arm lymphedema will be determined using a visual analogue scale (heaviness, swelling, pain, tightness). Measurements will be taken immediately pre- and post-exercise, and 24- and 72-hours post-exercise. Sample size: A sample size of 20 participants was calculated based on changes in L-Dex scores between baseline and 72-hours post exercise sessions. Findings from this study are relevant for exercise prescription guidelines, as well as recommendations regarding participating in activities of daily living for women following surgery for breast cancer and who may be at risk of developing arm lymphedema.

The purpose was to explore operable lung cancer patient experiences with an exercise intervention from a longitudinal perspective according to patient motivation and patient perceived benefits and barriers of exercise. Nineteen patients enrolled in an exercise intervention 2 weeks post-surgery participated in qualitative interviews at three time points. A criteria sampling strategy was applied. Ricoeur’s phenomenological hermeneutical philosophy inspired the analysis. Patients initiated exercising median 15 days postoperative. Eight patients included in the interview study dropped out of the intervention due to side effects of chemotherapy (n = 3) and external circumstances (n = 5). The mean attendance rate for the eleven participants who completed the intervention was 82 %. No patients experienced severe adverse events. Motivation for participation included patients’ expectations of physical benefits and the security of having professionals present. Patients experienced physical and emotional benefits and affirmed their social identity. Barriers were primarily related to side effects of chemotherapy. The exercise intervention was undertaken safely by operable lung cancer patients initiated 2 weeks after surgery. The intervention put the patients on track to a healthier lifestyle regarding physical activity and smoking. The study indicates that exercise initiated early in the treatment trajectory is beneficial for operable lung cancer patients and especially for those who were physically active and motivated pre-illness and who did not experience side effect of treatment.

Background: During cancer treatment children have reduced contact with their social network of friends, and have limited participation in education, sports, and leisure activities. During and following cancer treatment, children describe school related problems, reduced physical fitness, and problems related to interaction with peers.Methods/design: The RESPECT study is a nationwide population-based prospective, controlled, mixed-methods intervention study looking at children aged 6-18 years newly diagnosed with cancer in eastern Denmark (n = 120) and a matched control group in western Denmark (n = 120). RESPECT includes Danish-speaking children diagnosed with cancer and treated at pediatric oncology units in Denmark. Primary endpoints are the level of educational achievement one year after the cessation of first-line cancer therapy, and the value of VO_2maxone year after the cessation of first-line cancer therapy. Secondary endpoints are quality of life measured by validated questionnaires and interviews, and physical performance. RESPECT includes a multimodal intervention program, including ambassador-facilitated educational, physical, and social interventions. The educational intervention includes an educational program aimed at the child with cancer, the child’s schoolteachers and classmates, and the child’s parents. Children with cancer will each have two ambassadors assigned from their class. The ambassadors visit the child with cancer at the hospital at alternating 2-week intervals and participate in the intervention program. The physical and social intervention examines the effect of early, structured, individualized, and continuous physical activity from diagnosis throughout the treatment period. The patients are tested at diagnosis, at 3 and 6 months after diagnosis, and one year after the cessation of treatment. The study is powered to quantify the impact of the combined educational, physical, and social intervention programs.Discussion: RESPECT is the first population-based study to examine the effect of early rehabilitation for children with cancer, and to use healthy classmates as ambassadors to facilitate the normalization of social life in the hospital. For children with cancer, RESPECT contributes to expanding knowledge on rehabilitation that can also facilitate rehabilitation of other children undergoing hospitalization for long-term illness.Trial registration: Clinical Trials.gov: file.NCT01772849andNCT01772862

Introduction: Challenges exist in identifying, recruiting and motivating sedentary patients with cancer to initiate physical activity towards recommended levels. We hypothesise that the onset period of adjuvant chemotherapy can be ‘the open window of opportunity’ to identify and motivate sedentary patients with breast and colon cancers, at risk for developing coronary heart disease, to initiate and sustain lifestyle changes. Aims: To investigate the feasibility of oncologists/nurses screening for physical inactivity, in order to identify and recruit an at-risk population of sedentary patients with breast or colon cancer at the onset of adjuvant chemotherapy. Furthermore, the study will examine the adherence to one of two multimodal exercise interventions lasting 12 weeks; (1) hospital-based, high intensity, group exercise intervention (2) home-based, low intensity, individual, pedometer intervention. Both arms will be compared with a control group. Methods and analyses: All newly referred patients will be screened for sedentary behaviour, using national recommendations. Testing at baseline, 6, 12 and 39 weeks will include; (1) physiological testing (VO ₂ -peak, one repetition maximum muscle strength and lung function (2) fasting full body dual-energy X-ray absorptiometry scan (3) fasting blood glucose, insulin, lipids and cholesterols, (4) psychometric questionnaires (general well-being, quality of life, anxiety and depression, motivational readiness). The randomised controlled trial feasibility design is selected in order to examine barriers for recruitment, programme adherence, safety aspects and potential efficacy to the interventions during adjuvant chemotherapy. Ethics and dissemination: The Scientific Committee of the Capital Region (case No. H-1-2011-131) and the Danish Data Protection Agency (j. No. 2011-41-6349) approved the study. Data will be entered and locked into a database hosted by the Copenhagen Trial Unit, Rigshosptialet. Data will be available for analyses to project members and the trial statistician after the 45 included patients have completed the 12-week test. Results will be published in peer-reviewed scientific journals. Trial registration: Current Controlled Trials ISRCTN24901641 .

Lung cancer is the leading cause of cancer death in North America and Western Europe. Patients with lung cancer in general have reduced physical capacity, functional capacity, poor quality of life and increased levels of anxiety and depression. Intervention studies indicate that physical training can address these issues. However, there is a lack of decisive evidence regarding the effect of physical exercise in patients with advanced lung cancer. The aim of this study is to evaluate the effects of a twelve weeks, twice weekly program consisting of: supervised, structured training in a group of advanced lung cancer patients (cardiovascular and strength training, relaxation).

Patients with acute leukemia experience a substantial symptom burden and are at risk of developing infections throughout the course of repeated cycles of intensive chemotherapy. Physical activity in recent years has been a strategy for rehabilitation in cancer patients to remedy disease and treatment related symptoms and side effects. To date, there are no clinical practice exercise guidelines for patients with acute leukemia undergoing induction and consolidation chemotherapy. A randomized controlled trial is needed to determine if patients with acute leukemia can benefit by a structured and supervised counseling and exercise program.

Standard treatment for patients with disseminated germ cell tumors is combination chemotherapy with bleomycin, etoposide and cisplatin (BEP). This treatment is highly effective, but the majority of patients experience severe adverse effects during treatment and are at risk of developing considerable long-term morbidity, including second malignant neoplasms, cardiovascular disease, and pulmonary toxicity. One neglected side effect is the significant muscular fatigue mentioned by many patients with testicular cancer both during and after treatment. Very limited information exists concerning the patho-physiological effects of antineoplastic agents on skeletal muscle. The primary aim of this study is to investigate the effects of BEP-treatment on the skeletal musculature in testicular cancer patients, and to examine whether the expected treatment-induced muscular deterioration can be attenuated or even reversed by high intensity progressive resistance training (HIPRT).

Lung cancer patients experience loss of physical capacity, dyspnea, pain, reduced energy and psychological distress. The aim of this study was to explore feasibility, health benefits and barriers of exercise in former sedentary patients with advanced stage lung cancer, non‐small cell lung cancer (NSCLC) (III–IV) and small cell lung cancer (SCLC) (ED), undergoing chemotherapy. The intervention consisted of a hospital‐based, supervised, group exercise and relaxation program comprising resistance‐, cardiovascular‐ and relaxation training 4 h weekly, 6 weeks, and a concurrent unsupervised home‐based exercise program. An explorative study using individual semi‐structured interviews (n=15) and one focus group interview (n=8) was conducted among the participants. Throughout the intervention the patients experienced increased muscle strength, improvement in wellbeing, breathlessness and energy. The group exercise and relaxation intervention showed an adherence rate of 76%, whereas the patients failed to comply with the home‐based exercise. The hospital‐based intervention initiated at time of diagnosis encouraged former sedentary lung cancer patients to participation and was undertaken safely by cancer patients with advanced stages of disease, during treatment. The patients experienced physical, functional and emotional benefits. This study confirmed that supervised training in peer‐groups was beneficial, even in a cancer population with full‐blown symptom burden and poor prognosis.

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.Trial registration Current Controlled trials ISRCTN05322922.
