Berchuck JE, Meyer CS, Zhang N, et al. - Preexisting mental health disorders (MHDs) have been linked with greater mortality in people diagnosed with cancer, so researchers examined if cancer outcomes for people with preexisting mental health disorders improve in correlation with receiving mental health treatment. From the Veterans Affairs Central Cancer Registry, they took data from 55,315 veterans with newly diagnosed non–small cell lung cancer (NSCLC) between September 30, 2000 to December 31, 2011 for this retrospective, population-based cohort study. Among these, there were 18,229 individuals with a preexisting mental health disorder. Participation in mental health treatment programs and housing and employment support programs was noted to be associated with a decreased likelihood of being diagnosed with advanced cancer, a greater likelihood of receiving stage-appropriate treatment, and decreased all-cause and lung cancer–specific mortality in veterans with preexisting MHDs diagnosed with NSCLC. This may be the first study to show significant improvement in cancer mortality for patients with MHDs who participate in mental health treatment programs, housing support programs, or employment support programs. .
