EP03.01-005 Clinicopathological Features of ROS1-rearranged Adenocarcinomas: A Single Institutional Experience Spanning Four Years From India

Abstract

ROS1-rearranged (ROS1-R) adenocarcinomas represent a relatively uncommon but therapeutically targetable molecular subgroup of non-small cell lung carcinomas. Western literature estimates their prevalence at <1% of all non-squamous adenocarcinomas while the prevalence in Asian countries is slightly higher. Here, we present the clinicopathological features of ROS1-R adenocarcinomas diagnosed over the last 4 years from a tertiary care institution in India.
