应用大切片研究30例肺腺鳞癌并与102例单纯肺腺癌和鳞癌比较。肺腺鳞癌既有腺癌又有鳞癌的某些生物学特征,因而较腺癌或鳞癌更具侵袭性。3例腺鳞癌在电镜下同一癌细胞中常有腺癌及鳞癌细胞的两种超微结构成分。本文肺腺鳞癌的1,3,5年生存率低于单纯的腺癌和鳞癌。腺鳞癌生存率可能与所含腺癌成分的分化程度有关。
Large sections were used to study 30 cases of lung adenosquamous carcinoma and compared with 102 cases of simple lung adenocarcinoma and squamous cell carcinoma. Adenosquamous carcinoma of the lung has certain biological features of both adenocarcinoma and squamous cell carcinoma, and is therefore more aggressive than adenocarcinoma or squamous cell carcinoma. In 3 cases of adenosquamous carcinoma, there were often two ultrastructural components of adenocarcinoma and squamous cell carcinoma in the same cancer cell under electron microscope. The 1-, 3-, 5-year survival rate of lung adenosquamous carcinoma is lower than that of adenocarcinoma and squamous cell carcinoma. The survival rate of adenosquamous carcinoma may be related to the degree of differentiation of the adenocarcinoma components contained.
