Tetsuya Mitsudomi, MD, Professor at Kindai University in Japan and President of the International Association for the Study of Lung Cancer, commented on the negative results of the phase III randomized ITACA trial of adjuvant therapy customization.

“This trial confirmed that there is no biomarker strong enough to predict the efficacy of cytotoxic chemotherapy; however, the concept of customizing adjuvant therapy according to the genomic status of patients’ tumors is valid, leading to the recent demonstration in the ADAURA study¹ of the superiority of osimertinib in delaying the postoperative recurrence of disease in patients with EGFR-mutated non–small cell lung cancer,” Dr. Mitsudomi said.

“The ITACA study is the largest adjuvant study tailored to ERCC1 and thymidylate synthase status, and the results have been long awaited. This trial should be praised for the mandated genomic analysis that was accomplished within a reasonably short time frame before random assignment,” he commented.
