We reviewed post-operative complication and mortality rates from 1995 through 2014 and evaluated the changes in those rates across that 20-year period. Two thousand and three hundred sixteen patients with lung cancer underwent resection at our institution between 1995 and 2014. This timespan was divided into four 5-year periods. Each patientʼs age, Charlson comorbidity index score, and extent of surgery in each 5-year period were summarized, and the changes in these factors over the 20-year span were evaluated. The complication and mortality rates were calculated for each 5-year period, and the changes in those rates over the 20-years were evaluated. The number of patients with higher Charlson comorbidity index scores increased during the 20-year period. Of the 455 patients who developed complications, 97 developed life-threating complications. There were 16 post-operative deaths and 23 in-hospital deaths. There were no significant changes in the complication rate or mortality rate during the 20-year period. Both rates were significantly correlated with the extent of resection. Although the number of patients with comorbidities increased in the 20-year period, the post-operative complication and mortality rates, as well as in-hospital mortality, did not change significantly.
