Abstract

背景与目的同时性多原发肺癌(synchronous multiple primary lung cancer, sMPLC),既往属少见疾病,但近年来由于诊疗手段的进步检出率逐渐升高。但关于MPLC的发病机制、诊断、鉴别诊断和临床处理策略仍存在诸多争议。本研究对31例sMPLC的临床资料进行总结分析,进一步探讨sMPLC的诊断、治疗和预后。方法归纳总结31例sMPLC的临床资料,回顾性分析其诊断方法、手术方式、病理资料。结果所有患者均行胸腔镜手术,无死亡病例。术前均行薄层高分辨计算机断层扫描(computed tomography, CT)发现肺部多发结节。病灶位于同侧者均同期行手术治疗,手术方式以胸腔镜下肺叶+亚肺叶切除为主;病灶位于双侧者,均分期手术,时间间隔为3个月-4个月。结论薄层高分辨CT是术前诊断sMPLC的最佳方法。sMPLC同侧肺发病率高于双侧肺(23:8),周围型多见,占94%,组织学类型以腺癌最多见,占80.6%(25/31)。胸腔镜下主病灶的肺叶切除+次要病灶的亚肺叶切除是最常用的术式。
