对168例外科治疗肺腺癌病人分析，认为肺腺癌分化程度低，转移早，放疗、化疗效果差，手术治疗效果良好。常规肺叶切除加淋巴结清扫是常用术式；全肺切除并发症多，生活质量差，长期生存者少；气管、支气管袖状切除加淋巴结清扫术应多考虑，术中N2清除能明显提高5年生存率。对于术前已知为T3病人或术中发现已达T3者，手术切除应慎重，因这些病人无论手术否，均无长期生存者。 The analysis of 168 cases of surgical treatment of lung adenocarcinoma showed that the lung adenocarcinoma had low differentiation, early metastasis, poor radiotherapy and chemotherapy, and good surgical treatment. Conventional lobectomy plus lymphadenectomy is a commonly used procedure; Pneumonectomy has many complications, poor quality of life, and less long-term survival; tracheal and bronchial sleeve resection plus lymphadenectomy should be considered, and intraoperative N2 clearance can be significantly improved by 5 years. Survival rate. For patients known to have T3 preoperatively or who have reached T3 during surgery, surgical resection should be performed with caution, as these patients have no long-term survival regardless of surgery.
