Abstract
With advances in medical technology, theproportion of early-stage lung cancerhas been growing. Conforming to the trend of individualized treatment, sublobar resection for early stage lung cancer has been considered more valuable than ever before. Currently, there were still confilictions about the oncological validity of sublobar resection comparing with lobectomy for lung cancer. We reviewed the study status of the following contentious issues: the evidence based medicine, the indications of wedge resection or segmentectomy, the weight of tumor diameter and margin distance, and the choices for the elderly.
