The ADJUVANT study in patients with EGFR-mutant stage II or IIIA NSCLC who received either adjuvant therapy with gefitinib or chemotherapy with vinorelbine and cisplatin after surgery for 2 years of treatment, showed an improvement in median DFS of 28.7 months with gefitinib versus 18 months with chemotherapy [21]. Here, EGFR is linked to non-small cell lung carcinoma.
