Though I didn't make it to the American Association for Cancer Research (AACR) meeting in mid-April, I did catch discussion that followed presentation of some preliminary data from the Biomarker-integrated Approaches of Targeted Therapy for Lung Cancer Elimination (BATTLE) trial, conducted at MD Anderson Cancer Center over the last several years. My friend and colleague, Dr. Ed Kim, presented the provocative early results. The study enrolled 255 patients with previously treated advanced NSCLC who had previously received a median of two prior lines of therapy.
