Abstract
Lung cancer remains a leading cause of cancer-related mortality worldwide,and non-small cell lung cancer(NSCLC)accounts for approximately 85％of all lung cancer cases.For early-stage(stage I)NSCLC,surgical resection is the mainstay of treatment,with anatomical lobectomy having long been regarded as the standard procedure.In recent years,advances in imaging technologies and the wider implementation of early screening have renewed interest in segmentectomy,an anatomical sublobar resection that preserves more functional lung parenchyma.This review summarizes the evolution of segmentectomy,expansion of its indications,oncologic outcomes and recurrence risk,advantages in postoperative pulmonary function preservation,technical challenges,the impact of spread through air spaces(STAS)on procedure selection,current controversies,and future research priorities,with the aim of informing clinical decision-making.关键词
