【摘要】 本文报告原发性胃腺鳞癌4例,占本所同期胃癌的0.44％。作者讨论了本病的组织学起源,其中以腺癌鳞化发生腺鳞癌的可能性较大。它的起源方式可能与胃纯鳞癌有所不同。肿瘤中的腺癌和鳞癌两种成分可同时或分别转移,故提示它们的生物学行为存有差异。本病预后较差。治疗采用包括根治性手术、化疗等在内的综合治疗,但以根治性手术治疗为主。更多还原

【Abstract】 Four cases of primary adeno-squamous carcinoma of the stomach are reported. This accounts for 0.44% of all gastric cancer treated in our institute from 1970 through 1984. A possible mechanism for the ocurrence of the disease is squamous meta-plasia in a pre-existing glandular carcinoma. Its mode of origin may be somewhat dif-ferent from that of pure squamous cell carcinoma of the stomach. The two cytologic components may metastasize simultaneously or separately. The disease has a poor pog-nosis. Combined therapy including radical operation, chemotherapy, etc. is recom-mended, with an emphasis on radical resection.更多还原
