Clinicopathological characteristics and fatality rate of lung cancer patients in a grade-A tertiary hospital,2014-2018

Objective To investigate the clinicopathological characteristics and fatality rate of lung cancer patients in our hospital. Methods Clinical data about 6 006 patients with lung cancer admitted to our hospital from January 2014 to November 2018 were retrospectively analyzed,their clinicopathological characteristics and prognosis were analyzed. Results Of the 6 006 cases,male patients accounted for 64.87%,and patients over 60 years old accounted for 66.43%.The proportion of adenocarcinoma was 56.43%,higher than squamous cell carcinoma （16.86%） and small cell lung cancer （13.39%）.From 2014 to 2018,the number of patients with lung cancer admitted to the hospital showed an increasing trend,while the in-hospital fatality rate showed a decreasing trend(P_{linear by linear association}<0.001).The in-hospital fatality of adenocarcinoma patients （1.36%） was higher than that of squamous cell carcinoma （0.59%） and small-cell lung cancer （0.50%）,showing no significant difference;but all of them were significantly lower than the fatality rate of the other types （3.13%）. Conclusion Male and the elderly accounts for the majority of the hospitalized patients with lung cancer are male,and the in-hospital fatality decreases gradually over time.
