Key clinical poin t: Segmentectomy is noninferior to lobectomy for overall survival (OS) in patients with small-sized peripheral nonsmall cell lung cancer (NSCLC).
Major finding : Segmentectomy was noninferior to lobectomy for 5-year OS (94.3% vs 91.1%; hazard ratio 0.663; 95% CI 0.474-0.927; 1-sided P < .0001 for noninferiority). There were no differences between the groups in 5-year relapse-free survival.
Study details : The data come from a Japanese randomized controlled, noninferiority phase 3 trial (n = 1106) of segmentectomy vs lobectomy for stage IA NSCLC.
Disclosures: The trial was funded by the National Cancer Center Research and the Ministry of Health, Labor, and Welfare of Japan. R Nakajima, T Aoki, J Okami, H Ito, N Okumura, M Yamaguchi, K Nakamura, and S Nakamura reported no competing interests. The other authors reported ties with one or more pharmaceutical companies outside this work.
