RET and non-small cell lung carcinoma: The NSCLC RET fusion-positive cohort was significantly younger (median age = 64 vs 68; P < 0.001), had a higher female:male ratio (1.27 vs 1.02; P = 0.012) and had a higher frequency of specimens obtained from metastatic sites vs nonmetastatic sites (52% vs 43%; P = 0.002) when compared to the NSCLC RET fusion-negative cohort (Table 2).
