CTNNB1 and non-small cell lung carcinoma: To confirm this relationship, an analysis of 12,261 patients with NSCLC from the cBioPortal database showed mutual exclusivity of CTNNB1 and TP53 (Log2 odds ratio, –0.663; P < .001; q < 0.001),8 suggesting that this association is not limited to EGFR-mutated patients.
