PURPOSE: To evaluate the feasibility and outcomes of a tailored, goal-directed, and exercise-based physical therapy program for patients with metastatic breast cancer (MBC).METHODS: This was an observational, uncontrolled feasibility study. The physical therapy intervention was highly tailored to the individual patient's goals, abilities, and preferences and could include functional, strength, aerobic, and relaxation exercises. Feasibility outcomes were participation rate (expected: 25%), safety, and adherence (percentage of attended sessions relative to scheduled sessions). Additional outcomes were goal attainment, self-reported physical functioning, fatigue, health-related quality of life, and patient and physical therapist satisfaction with the program.RESULTS: Fifty-five patients (estimated participation rate: 34%) were enrolled. Three patients did not start the intervention due to early disease progression. An additional 22 patients discontinued the program prematurely, mainly due to disease progression. Median intervention adherence was 90% and no major intervention-related adverse events occurred. A goal attainment score was available for 42 patients (of whom 29 had completed the program and 13 had prematurely dropped out). Twenty-two (52%) of these patients achieved their main goal fully or largely and an additional 15 patients (36%) partially. Eighty-five percent would "definitely recommend" the program to other patients with MBC. We observed a modest improvement in patient satisfaction with physical activities (Cohen's dz 0.33).CONCLUSION: The tailored intervention program was feasible in terms of uptake, safety, and outcomes and was highly valued by patients and physical therapists. However, disease progression interfered with the program, leading to substantial dropout.TRIAL REGISTRATION: NTR register: NTR6475.

ObjectivesThe existing studies among workers with a past cancer diagnosis have rarely focused on workers confronted with cancer recurrence or metastases specifically, so knowledge is lacking. The aim of this study, therefore, was to investigate the work functioning (work ability, burnout complaints, and work engagement) of workers with recurrent or metastasized cancer. Furthermore, the association of psychological capital (hope, optimism, resilience, and self-efficacy) with work functioning was studied.MethodsData from a survey study among workers 2–10 years past cancer diagnosis were used (N = 750); 73% reported a diagnosis of breast cancer and 27% a diagnosis of cancer other than breast cancer. Analysis of variance was used to compare participants with and without cancer recurrence or metastases regarding work functioning (work ability, burnout complaints, and work engagement) and psychological capital (hope, optimism, resilience, and self-efficacy). Multivariate regression analyses were used to analyze the association of type of cancer and psychological capital with work functioning among workers with cancer recurrence or metastatic cancer (n = 54), controlling for age.ResultsWork ability is significantly lower among workers with cancer recurrence or metastases (controlling for age); however, burnout complaints and work engagement are at comparable levels. Among workers with cancer recurrence or metastases, a higher level of hope is positively associated with work ability and work engagement, and a higher level of hope or resilience is negatively associated with burnout complaints.Significance of resultsAmong workers with cancer recurrence or metastases, work ability needs attention. Furthermore, especially the element hope of psychological capital is important to focus on because of the association with more favorable work functioning in general. The clinical psycho-oncological practice may benefit from these insights in guiding this vulnerable group of workers who are living with active cancer and many uncertainties.

INTRODUCTION: An optimal relative dose intensity (RDI) of adjuvant chemotherapy is associated with better survival in patients with breast cancer. Little is known about the role of physical fitness in attaining an adequate RDI in patients with early stage breast cancer. We investigated the association between pre-treatment physical fitness and RDI in this population.METHODS: We pooled individual patient data from two randomized exercise trials that studied exercise programs in early breast cancer: the PACES (n = 230) and the PACT (N = 204) study. Logistic regression models were used to evaluate the association between pre-treatment fitness and achieving an optimal RDI (≥85%). In addition, we added an interaction term to the model to explore the potential moderating effect of participating in an exercise program.RESULTS: Data were available for 419 patients (mean age at diagnosis 50.0 ± 8.6 years). In the total sample, lower pre-treatment physical fitness was associated with significantly lower odds of achieving ≥85% RDI: age-adjusted OR 0.66 [95%CI 0.46-0.94]. In patients allocated to the supervised exercise intervention during chemotherapy (n = 173), the association between pretreatment physical fitness and RDI was almost completely mitigated (OR 0.95 (95%CI 0.54-1.56)), while it was more pronounced in patients who received care as usual (n = 172, OR 0.31 (95%CI 0.13-0.63) pinteraction: 0.022).CONCLUSION: Early stage breast cancer patients with relatively lower levels of pretreatment physical fitness have lower odds of achieving an optimal dose of chemotherapy. Given that physical fitness is modifiable and our results suggest that following a moderate-to-high intensity exercise training during chemotherapy could improve treatment completion, clinicians should not refrain from referring patients to supportive exercise programs because of low fitness.
