Concerns About Lung Cancer Among Prisoners
Lung(2018)
Abstract
Background Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients. Method We performed a multi-center observational case–control study. Cases were prisoners diagnosed with lung cancer from 2005 to 2013. Controls were non-prisoner lung cancer patients selected from hospital databases and randomly matched to cases (targeted case–control ratio: 1:3). Incidence rates in both groups were calculated using national statistics. Results Seventy-two cases and 170 controls met inclusion criteria. Cases were mainly men (99%). Mean age at diagnosis was 52.9 (± 11.0) in cases and 64.3 (± 10.1) in controls ( p < 0.0001). More case patients were current smokers compared to control patients (83% vs 53%; p < 0.0001). We found no significant differences between the two groups as concerns histologic types, TNM stages at diagnosis, initially-employed treatments, times to management or survival. Incidence rates (2008–2012) in male prisoners were higher than those in the general population in all concerned age groups. Conclusion There is a shift of lung cancer toward young people in prisons. However, the presentation, management, and prognosis of lung cancer are similar between prisoners and non-prisoners. These finding could justify a specific screening policy for the incarcerated populations.
