The role of operability has not been previously considered as a confounder. Methods We queried the National Cancer Database for T4M0 LC diagnosed 2004–2015. Patients were categorized as undergoing LGX, chemoradiotherapy but operable (LP-operable), and chemoradiotherapy inoperable (LP-inoperable). Overall survival (OS) was estimated by Kaplan–Meier. Cox multivariate analysis (MVA) identified variables associated with OS. Results We identified 1405 LGX, 164 LP-operable and 1969 LP-inoperable patients. Compared with LGX, MVA demonstrated worse OS among LP-inoperable (HR 1.28 95%CI 1.17–1.40, p < 0.01) but not LP-operable patients (HR 1.12 95%CI 0.91–1.39, p = 0.28). Conclusions LP-operable patients did not have significantly worse OS than those undergoing LGX. View on Web
