Here, COX2, TOPK, and MET expression were examined in EGFR-activating mutated NSCLC...of 153 patients with EGFR-activating mutations, we identified that the PFS of gefitinib-resistant patients who were COX2, MET, and TOPK triple-positive was shorter than that of patients who were triple-negative…These results indicated that triple-positive patients with COX2, MET, and TOPK had a worse prognosis.
