作者在1968年1月至1972年12月间用肺切除治疗的434例支气管癌中,有64例(14.7%)在切除标本的支气管切缘有显微镜下残留癌,随访至1978年6月,其五年生存率为23.4%(15例),和一般报告的支气管癌切除后五年存活率22～41%相差不大。
Of the 434 cases of bronchial carcinoma treated by pneumonectomy between January 1968 and December 1972, 64 (14.7%) had microscopic residual cancer at the bronchial margin of the resected specimen. Follow-up was made until June 1978. The five-year survival rate was 23.4% (15 cases), and the general reported 5-year survival rate of bronchial carcinoma after resection was 22 to 41%.
