A behavioural approach in the development of work-related interventions for cancer survivors: an exploratory review.

The application of behavioural change models and theories has not been studied, and behavioural determinants have not been considered, in the context of cancer and work. The aim of this study is to assess the relevance of a behavioural approach in the development of work-related interventions for cancer survivors. Two search strategies were conducted to identify studies on (1) lifestyle interventions (exercise, smoking, alcohol intake and diet), based on behavioural models and theories, in cancer survivors; (2) behavioural determinants regarding work. Medline, Embase, PsycInfo, CINAHL and the Cochrane Controlled Trial Register were searched (2000-2015). Studies were assessed on their eligibility, and findings were listed and categorised. Thirty-four studies exploring lifestyle interventions in cancer survivors were retrieved. The behavioural change models and theories most regularly used were the Transtheoretical Model and Social Cognitive Theory. Furthermore, 26 studies on the role of behavioural determinants regarding work were found. The most frequently considered determinants were self-efficacy, social norms, workers' expectations towards work or recovery, attitude, motivation and meaning of work. The results indicate the significance of behavioural change models and theories and of behavioural determinants in related research areas, which encourages a behavioural approach in the development of work-related interventions for cancer survivors.

Employment and social benefits up to 10 years after breast cancer diagnosis: a population-based study.

BACKGROUND: Little is known about employment outcomes after breast cancer (BC) beyond the first years after treatment. METHODS: Employment outcomes were compared with a general population comparison group (N=91 593) up to 10 years after BC for 26 120 patients, diagnosed before age 55 between 2000-2005, with income and social benefits data from Statistics Netherlands. Treatment effects were studied in 14 916 patients, with information on BC recurrences and new cancer events. RESULTS: BC survivors experienced higher risk of losing paid employment (Hazard Ratio (HR): 1.6, 95% Confidence Interval (95% CI) 1.4-1.8) or any work-related event up to 5-7 years (HR 1.5, 95% CI 1.3-1.6) and of receiving disability benefits up to 10 years after diagnosis (HR 2.0, 95% CI 1.6-2.5), with higher risks for younger patients. Axillary lymph node dissection increased risk of disability benefits (HR 1.5, 95% CI 1.4-1.7) or losing paid employment (HR 1.3, 95% CI 1.2-1.5) during the first 5 years of follow-up. Risk of disability benefits was increased among patients receiving mastectomy and radiotherapy (HR 1.2; 95% CI 1.1-1.3) and after chemotherapy (HR 1.7; 95% CI 1.5-1.9) during the first 5 years after diagnosis. CONCLUSIONS: BC treatment at least partly explains the increased risk of adverse employment outcomes up to 10 years after BC.
