Trends in survival based on treatment modality in non-small cell lung cancer patients: a population-based study

Objectives — We examined the trends in survival based on treatment modality among non-small cell lung cancer (NSCLC) patients in the province of Ontario, Canada, from 2007 to 2015.

Methods — We investigated the trends in survival based on treatment modality.

Results — Among 56,417 identified patients, the mean age at diagnosis was 70.1 years (SD = 10.7). Treatment modalities varied significantly over time (p<.001). Overall, 23.0% of patients received surgical treatments. We observed more than 20% increase in five-year survival rates for all surgical groups over time.

Conclusions — Patients undergoing sublobar/lobar resections had higher survival rate.
