Background
A return to work (RTW) is a challenge for survivors of oral cancer. Further light could be shed on the RTW of patients with oral cancer, which remains largely uninvestigated. The objective of this study was to investigate the trajectories of RTW and their impact on survival in workers with oral cancer.
Methods
In total, 12,222 workers who were newly diagnosed with oral cancer were identified during the period from 2004 to 2015 and were included in this cohort study. The associations between independent variables and RTW were analyzed using Cox proportional hazard models.
Results
Overall, 8793 workers returned to work in the first years after a diagnosis of oral cancer. Chemotherapy (hazard ratio [HR], 0.88; 95% CI, 0.78â0.99) and radiation therapy (HR, 0.83; 95% CI, 0.75â0.92) were inversely associated with RTW. Patients who had received surgical treatment (HR, 1.24; 95% CI, 1.01â1.53) were more likely to RTW. Employees with stage I (HR, 1.66; 95% CI, 1.47â1.87), stage II (HR, 1.52; 95% CI, 1.35â1.72), and stage III (HR, 1.32; 95% CI, 1.16â1.51) disease were associated with an increased likelihood of RTW in the fifth year after diagnosis. KaplanâMeier survival analysis demonstrated better survival for the RTW group versus the nonâRTW group in patients with stage III and IV oral cancer (PÂ <Â .001). The fully adjusted HR indicated that the RTW group had significantly better outcomes than the nonâRTW group in allâcause mortality (PÂ <Â .001; HR, 0.36; 95% CI, 0.33â0.39).
Conclusions
Sociodemographic and medical factors affect the RTW of cancer survivors. RTW may have a beneficial effect on survival of patients with oral cancer.
