亚肺叶切除术治疗早期非小细胞肺癌时肺切缘的研究进展

Progress of Lung Margin During Sublobar Resection for Early-staged Non-small Cell Lung Cancer

近年来随着低剂量计算机断层扫描(low-dose computed tomography,LDCT)、高分辨率CT(highresolution CT,HRCT)的普及,早期非小细胞肺癌的发现比率不断上升,越来越多的胸外科医生探索手术方式的改良,推动手术切除范围向更加合理的方向进展。临床研究发现肺切缘阴性较阳性有更低的局部肿瘤复发率,因此亚肺叶切除术治疗早期肺癌术中保证肺切缘阴性具有重要的临床意义,本文将就这一领域研究现状和进展作一综述。

In recent years, with the popularization of low-dose computed tomography（LDCT） and high-resolution CT（HRCT）, the discovery rate of early-staged non-small cell lung cancer has been on the rise, and more thoracic surgeons have explored more reasonable resection scope. Clinical studies have demonstrated that there is a lower rate of local tumor recurrence in patients with negative lung margins compared with positive ones. Therefore, it is of great clinical significance to ensure the negative margin during sublobar resection for early-staged lung cancer. This paper will focus on this area.
