Risk factors for locoregional relapse after segmentectomy: Supplementary analysis of the JCOG0802/WJOG4607L trial
The JCOG0802/WJOG4607L trial revealed superior overall survival in segmentectomy to lobectomy for small-peripheral non-small-cell lung cancer. However, locoregional relapse (LR) is a major issue for segmentectomy. An ad hoc supplementary analysis aimed to determine the risk factors for LR and the degree of advantages of segmentectomy based on primary tumor sites.
