In particular, a better OS rate occurred in patients with good ECOG performance status (14 vs. 4 months, p = 0.000), and the OS was marginally better among patients who had never smoked (14 vs. 9 months; p = 0.088) or those with a mutated EGFR tumor (10 vs. 17 months, p = 0.098; Figure 1B, 1C). This evidence concerns the gene EGFR and neoplasm.
