FP12.07 Clinico-demographic Factors, EGFR status and their association with Stage at Diagnosis in Lung Adenocarcinoma Patients

Abstract

Compared to advanced or metastatic lung adenocarcinomas, are there differences in the distribution of clinico-demographic factors such as age, sex, race, smoking status, and EGFR status in patients with earlier stage of disease at diagnosis? One large Korean study found a significant association between EGFR-mutated non-small cell lung cancers and diagnosis at an early stage; however, this and prior published studies exploring this relationship typically involved populations that were race-specific (e.g.
