由于经胸膜活检有导致肿瘤播散的潜在危险 ,日本Ｓａｗａｂａｔａ等评估了经胸膜活检（针吸活检或切取肿瘤活检）诊断外周肺癌是否会影响肿瘤复发及预后。Ｓａｗａｂａｔａ等回顾分析了１９９０年～１９９８年接受手术的２３９例病人。所选病例均为非小细胞肺癌 ,肿块最大直径 Due to the potential risk of transmissibility of pleural biopsy, Japan Sawabata et al assessed whether the diagnosis of peripheral lung cancer by peritoneal biopsy (needle aspiration biopsy or excisional tumor biopsy) would affect tumor recurrence and prognosis. Sawabata et al retrospectively analyzed 239 patients who underwent surgery between 1990 and 1998. Selected cases are non-small cell lung cancer, the largest diameter of the tumor
