筛查发现的小体积非小细胞肺癌治疗相关的问题探讨——术中定位、切除范围、淋巴结清扫

Issues Relevant to Surgical Intervention in 'Tiny' Non-small Cell Lung Cancer Detected by 'Lung Screening'--Orientation, Lung Resection and Lymph Node Resection

随着胸部计算机断层扫描(computed tomography,CT)的广泛应用,以及肺癌高危人群筛查的逐渐开展,越来越多的"小肺癌"被发现及诊断。"小肺癌"具有的术中定位困难、侵袭性弱、近期和远期预后较好的特点为肺癌的外科治疗提出了新的挑战,本文着重从肺癌的筛查、小结节定位、肺叶切除与亚肺叶切除以及淋巴结清扫范围等方面对"小肺癌"带来的挑战进行探讨。

With the widely application of chest computed tomography（CT） and gradual generalization of lung cancer screening project for high risk populations, more and more ＂tiny lung cancers＂ were identified. Due to the difficulty in intraoperative orientation, their less aggressiveness, and excellent short/long term prognosis, the ‘tiny lung cancers＇ posed new challenges for the surgery in the treatment of lung cancer. In this review, theirfore, we focused on these challenges and presented the progress in lung cancer screening, orientation of lung nodules, lobectomy and sublobectomy, and lymph node dissection.
