Aim:
Non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancers. Although curative treatment is surgery in the early stages, disease relapse is common. In this study, we retrospectively evaluated the prognostic factors and outcomes of operated NSCLC cases.
Materials and Methods:
Retrospective analysis of data from 166 patients with early stage NSCLC who presented after surgery and treated and followed in our clinic between 2006-2018 was performed. Histopathologic features and clinical findings were investigated as prognostic factors.The findings were analyzed using SPSS.
Results:
At the time of diagnosis, median age was 61 (39-82) and 84% of the patients were male. Most common pathologic subtype was adenocarcinoma. Median disease free survival (DFS) and overall survival (OS) were 76 months (%95CI:32.1-110.0) and 87 months (95%CI:59.8-114.1). ). In multivariate analysis, presence of vascular invasion was found to be independent prognostic factors for both DFS and OS (HR:2.5 and 2.3, respectively). Adenocarcinoma solid pattern was only associated with worse disease-free survival (HR: 1.7).
Conclusion:
In our study, we showed that the presence of vascular invasion and solid-type adenocarcinoma is associated with poor survival.
