Background: The consequences of cancer on working life until retirement age remain unclear. This study aimed to analyse working life considering all possible labour market states in a sample of workers after an SA due to cancer, and to compare their working life paths to those of a sample of workers without SA and with an SA due to other diseases.
Methods: Registry-based cohort study of social security affiliates in Catalonia from 2012-2018. Cases consisted of workers with an SA due to cancer between 2012-2015 (N=516) and were individually age- and sex-matched with an affiliate with an SA due to other diagnoses and a worker without an SA. All workers (N=1,548, 56% women) were followed-up from the end of the SA due to cancer until the end of 2018 to characterise eight possible weekly labour states. Sequence analysis, optimal matching, and multinomial logistic regression were used to identify and assess the probability of future labour market participation patterns (LMPP). All analyses were stratified by sex.
Results: Compared with workers with an SA due to cancer, male workers with no SA and SA due to other causes showed a lower probability of being in the LMPP of death (aRRR 0.02, 95% CI: 0.00‒0.16; aRRR 0.17, 95% CI: 0.06‒0.46, respectively), and in women lower probability of increasing permanent disability and death (aRRR 0.24, 95% CI: 0.10‒0.57; aRRR 0.39, 95% CI: 0.19‒0.83, respectively). Compared to workers with SA due to cancer, risk of future retirement was lower in workers with no SA (women aRRR 0.60, 95%CI: 0.22‒1.65; men aRRR 0.64, 95%CI: 0.27‒1.52).
Conclusions Workplaces should be modified to the needs of cancer survivors, many of which are common to all diagnoses, in order to prevent more frequent retirement and permanent disability when possible. Further studies should assess the impact of cancer on premature exit from the labour market among survivors, depending on cancer localisation and type of treatment.
