Concerns About Lung Cancer Among Prisoners

Area of Science:

• Oncology
• Epidemiology
• Public Health

Background:

• Prisoners may have an increased risk of lung cancer, with prior research indicating earlier onset.
• The CARCAN study addresses the limited research on lung cancer within the incarcerated population.

Purpose of the Study:

• To assess epidemiological characteristics of lung cancer in prisoners.
• To compare lung cancer management and prognosis between prisoners and non-prisoners.
• To determine lung cancer incidence rates in incarcerated individuals.

Main Methods:

• A multi-center, observational case-control study was conducted.
• Prisoner lung cancer cases (2005-2013) were compared to matched non-prisoner controls (1:3 ratio).
• Incidence rates were calculated using national statistics for both groups.

Main Results:

• Lung cancer was diagnosed at a younger age in prisoners (mean 52.9 years) compared to controls (mean 64.3 years).
• Prisoners had higher rates of current smoking (83% vs 53%) and higher incidence rates.
• No significant differences were observed in histologic types, TNM stages, treatment, or survival between groups.

Conclusions:

• Lung cancer presents earlier in the incarcerated population.
• Despite earlier onset, lung cancer presentation, management, and prognosis are comparable between prisoners and non-prisoners.
• Findings support the development of specific lung cancer screening policies for prisoners.
