Background: Cognitive problems are common in non-central nervous system cancer survivors. These problems are perceived as an important contributor to decline in work performance and work ability. Various interventions for cognitive problems have been proposed, but effectiveness regarding work-related outcomes has not yet been established. Effective treatment options to alleviate the adverse influence of cognitive problems on work performance are needed for working cancer survivors. In this paper, we will describe the design of a randomized, controlled, multicenter trial that evaluates the (cost-)effectiveness of an Internet-based cognitive rehabilitation program for occupationally active cancer survivors confronted with cognitive problems., Methods/ Design: A three-armed randomized controlled trial will be conducted, including two intervention groups (i.e., basic and extensive cognitive rehabilitation program) and one waitlist control group. In total, 261 cancer survivors (18-65 years) who have returned to work and who experience cognitive problems will be recruited. Patients with and without cognitive impairment as established in a neuropsychological assessment will be eligible; stratification will take place based on the presence of this cognitive impairment. The extensive intervention arm will contain a comprehensive training program (including psycho-education, fatigue management, and cognitive strategy training) with individual guidance (blended intervention). The basic intervention arm will contain a brief cognitive training program (including psycho-education and fatigue management) without individual guidance. The primary outcome will be accomplishment of an individually defined work-related treatment goal. Secondary outcomes include, among others, subjective cognitive functioning, work functioning, and quality of life. Primary and secondary outcomes will be measured at baseline (T0) and at 12 weeks (T1) and 26 weeks (T2) post-randomization., Discussion: About 40-50% of the cancer patients worldwide are of working age at time of diagnosis. Many of the occupationally active cancer survivors experience cognitive problems. Both from an individual and a societal perspective, it is important to sustain cancer survivors' employability. An effective treatment to alleviate the impact of cognitive decline and to improve work ability might help cancer survivors to sustain employability., Trial Registration: ClinicalTrials.gov NCT03900806 .

Purpose: Cognitive symptoms are reported to affect cancer survivors' functioning at work. However, little is known about the type of cancer treatment and cognitive symptoms in working cancer survivors. We examined the longitudinal association between type of cancer treatment and cognitive symptoms in cancer survivors post return to work, and whether the course of cognitive symptoms over 18 months differed per type of cancer treatment., Methods: Data from the Dutch longitudinal "Work-Life after Cancer" study were used. The study population consisted of 330 working cancer survivors who completed questionnaires at baseline, and 6, 12, and 18 months follow-up. Cognitive symptoms were assessed with the cognitive symptom checklist-work and linked with cancer treatment data from the Netherlands Cancer Registry. Data were analyzed using generalized estimating equations., Results: Cancer survivors who received chemotherapy reported comparable memory symptom levels (b: - 2.3; 95% CI = - 7.1, 2.5) to those receiving locoregional treatment. Executive function symptom levels (b: - 4.1; 95% CI = - 7.8, - 0.4) were significantly lower for cancer survivors who received chemotherapy, compared with those receiving locoregional treatment. In cancer survivors who received other systemic therapy, memory (b: 0.4; 95% CI = 0.1, 0.7) and executive function symptom levels (b: 0.4; 95% CI = 0.0, 0.7) increased over time. In cancer survivors who received chemotherapy and locoregional treatment, memory and executive function symptom scores were persistent during the first 18 months after return to work., Conclusions: The contradictory finding that cancer patients receiving chemotherapy report fewer cognitive symptoms warrants further research., Implications for Cancer Survivors: Working cancer survivors may have cognitive symptom management needs irrespective of the type of cancer treatment they received.

Our purpose was to investigate the possible mediating role of active coping and passive coping between self-reported health complaints and functional limitations, as assessed by an insurance physician (IP), self-assessed work ability and work status in cancer survivors on long-term sick leave. Validated questionnaires were used for self-reported health complaints, work ability and work status. The functional limitations of the respondents were transformed into scales for mental and physical limitations and limitations in working hours. Using LISREL, we constructed a model with coping in a mediating role. Active coping mediated between fewer self-reported physical limitations, more depressive symptoms, better cognitive functioning and more fatigue on the one hand, and more physical limitations and limitations in working hours on the other hand. Passive coping played no mediating role and was associated with more self-reported depressive symptoms only. More functional limitations were associated with lower self-assessed work ability of cancer survivors, and with not being at work, whereas higher self-assessed work ability was associated with being at work. Regarding the role of active and passive coping strategies in cancer survivors on long-term sick leave, more longitudinal research is needed to confirm causality., (© 2018 John Wiley & Sons Ltd.)
