Concurrent TP53 mutations with other targetable mutations were rare events: in study by Aisner et al. [25], in addition to 35 EGFR-mutant lung adenocarcinomas, TP53 mutations were also identified in 22 KRAS mutant and 11 ALK or ROS1 or RET rearranged tumors, however, prognosis information for these patients were not available. Here, ROS1 is linked to lung adenocarcinoma.
