TECHNICAL ADVANCES IN SUBLOBAR RESECTION FOR EARLY-STAGE LUNG CANCERS: REVIEW OF PREOPERATIVE PLANNING, TUMOR LOCALIZATION, IDENTIFICATION OF RESECTION LINES, AND CURATIVE RESECTION WITH SUFFICIENT SURGICAL MARGINS

Recent clinical studies have reported good outcomes of sublobar resection for early-stage lung cancers, increasing the necessity for limited resection. However, sublobar resection can be challenging in some cases due to difficulty in localizing impalpable small tumors, complex segmental anatomy, and difficulty in confirming the appropriate resection lines. These problems may lead to resection with insufficient surgical margins, increasing the possibility of locoregional recurrences and having negative effects on patients’ survival. There are several techniques to achieve appropriate sublobar resection and prevent recurrences: preoperative planning; tumor localization; identification of resection lines; and curative resection with sufficient surgical margins. We review the published evidence and discuss recent advances in these techniques.
