Abstract

Introduction: Oncogene-addicted non-small cell lung cancer (NSCLC) patients present a high incidence of CNS metastases either at diagnosis or during the course of the disease. In this case, patients present with worse prognosis and are often excluded from clinical trials unless brain metastases are pre-treated or clinically stable.

Areas covered: As a result of the discovery of several oncogenic drivers in ALK/ROS1/NTRK-positive NSCLC, targeted agents have been tested in several trials. We evaluate and compare the intracranial efficacy of available targeted agents in ALK/ROS1/NTRK-positive NSCLC based on subgroup analysis from pivotal trials.

Expert opinion: Last-generation ALK inhibitors have shown slightly superior intracranial activity but pivotal trials do not consider the same endpoints for intracranial efficacy, therefore data are not comparable. Local treatments for BM including surgical resection, stereotactic radiosurgery (SRS) and WBRT, should be integrated with systemic therapies basing on specific criteria like presence of oligoprogression or symptomatic progression.

Keywords: ALK; NSCLC; NTRK; ROS1; oncogene-addicted; treatment.
