Among EGFR tested patients, 1,173 (30%) were positive, 2,618 (67%) negative and 125 (3%) had unknown status. Median survival time was 858 days and 390 days for TKI (Y/N). Adjusted HR for TKI (Y/N) was 0.61; 95%CI = 0.58-0.64; p < 0.001)...These findings reveal remarkably increased survival for EGFR positive patients treated with TKI.
