Comparing to low UGT2B7 expression, patients with high UGT2B7 expression had significant poor overall survival among never‐smoking female Asian lung adenocarcinoma patients with EGFR mutation (HR = 4.80, 95% CI = 1.18–14.21, p = 0.027) (Figure 4B). This evidence concerns the gene UGT2B7 and lung adenocarcinoma.
