Abstract
BACKGROUND: Adenosquamous carcinoma (ASC) is a rare subtype of lung cancer, it is mixed glandular and squamous cell carcinoma with a more aggressive behavior and poor prognosis than the other histologic subtypes. The aim of the study was to explore the clinicopathological characteristics and prognostic factors of ASC. METHODS: A total of 72 patients were enrolled. We investigated clinicalpathological features and prognostic factors retrospectively. RESULTS: The overall 72 ASC patients' median age was 34.7 months, 5-year survival rate was 14.9%. The influence of tumor size, M stage, and N stage, gene mutation and surgery on the prognosis of patients show statistical significance. CONCLUSIONS: ASC is characterized by both histologic aggressiveness and adverse prognosis. We suggest the comprehensive therapy based on surgery, and given small molecule tyrosine kinase inhibitors (TKIs) treatment may prolong patients' overall survival.
