据报告多发的原发性肺癌少见,平均发病率1.6%,且主要是鳞癌。本文对病理诊断的62例肺腺癌进行了手术切除,将其标本每隔1～1.5cm 横断切面作仔细的病理检查。多中心性肺腺癌的诊断标准:①肿瘤之间在解剖上是分离的;②肿瘤之间组织学不同;③不包括淋巴结转移、肺外的转移瘤和切除部位周边的肿瘤复发。结果Ⅰ组:单纯腺泡型33例,平均年龄62.7岁,
It is reported that multiple primary lung cancers are rare, with an average incidence of 1.6%, and it is mainly squamous cell carcinoma. In this article, 62 cases of pathological diagnosis of lung adenocarcinoma were surgically resected, and their specimens were carefully examined every 1 to 1.5 cm of cross-section. The diagnostic criteria for multicenter lung adenocarcinoma are: 1) The tumors are anatomically separated; 2) The histology of the tumors is different; 3) Metastasis of lymph nodes, extrapulmonary metastases, and tumor recurrence around the resection site are not included. Results Group I: 33 cases of simple alveolar type, average age 62.7 years,
