The EGFR + group showed a nonsignificant trend of longer mOS than the EGFR − group (7.92 vs 11.52 months, P =0.927) ( Table 2 and Figure 1A ).

The study showed a trend of better OS in a patient with strong ALK expression, but due to the shortage of tissue sample, fluorescent in situ hybridization (FISH) for ALK could not be performed.
