肺癌转移相关因素分析

METASTASIS FACTOR OF LUNG CANCER

分析1990年6月～1992年6月收治的134例肺癌放疗前的X线片,CT扫描片的改变。肺癌纵隔各区淋巴结的转移以主支气管旁和肺门区为最多,纵隔与锁骨上淋巴结转移以同侧多见:锁骨上淋巴结转移与上纵隔淋巴结转移关系密切;远处播散与病理类型、锁骨上转移及大血管受侵情况有关:25例出现声哑,为左声带麻痹所致,11例出现上腔静脉综合症,以右肺为多。

Factors related to metastasis in 134 lung cancer patients were analysed on basis of chest films, CT scans and clinical findings. There were 65 squamous cell carcinoma, 24 adenocarcinoma, 23 small cell undifferentiated carcinoma. 17 undifferentiated carcinoma, 1 large cell undifferenti-ated carcinoma, 1 combined squamous and adenocarcinoma and 3 unclassifiable carcinoma. Most of the lymph node metastasis were in the 5th, 6th, 7th and 8th regions of the mediastinam. Metastasis to the mediastinal and supraclavicular lymph nodes occurred on the same side, 84. 9% 30. 3% for lesions in the right lung and 83. 4%, 14. 7% for lesions in the left lung. The supra-claviculor metastasis developed following the involvement of the mediastinum. 19. 4% (26) patients developed hematogenous spread to the bone, brain, liver, adrenal, pancreas and the con-tralateral lung. Small cell type and patients with positive sapraclavicular metastasis were proved to develop hematogenous spread.
