the clinic pathologic characteristics and survival of patients with lung cancer in the west of iran; a cross-sectional study

Background: lung cancer (lc) is the most commonly occurring cancer worldwide. objectives: we aimed to evaluate the clinicopathological characteristics of lc and the survival rates for each type. methods: in a retrospective study, medical records from 313 lc patients referred to a clinical center in kermanshah, iran (2010 - 2019) were extracted and reviewed. statistical analysis was conducted using spss 22 and stata 15 software. results: of the 313 patients, 91 (29.1%) were female and 222 (70.9%) were male, with a mean age of 61.17 ± 14.37 years. non-small cell carcinoma (nsclc) was the most common morphology (76.6%), which was associated with smoke exposure. the five-year survival rate, according to the kaplan-meier method, was 12%. there were statistically significant differences between gender, age groups, and smoke exposure with tumor classification (p < 0.05). the age group > 50 years was associated with a higher mortality rate in univariate analysis (hr: 2.034; 95% ci: 1.046 - 3.955, p = 0.036). conclusions: the five-year survival rate of lc was consistent with previous reports worldwide (less than 15%). the age group > 50 years was identified as a risk factor for lc and higher mortality rates.
