摘要 目的:探讨p16蛋白表达与食管癌发生发展的关系.方法:应用免疫组织化学方法检测了79例食管癌(原位癌30例,浸润性鳞状细胞癌19例,腺癌30例)及其116例增生性病变(单纯增生30例,不典型增生轻31例、中31例、重24例)和28例正常食管黏膜上皮组织中p16蛋白表达情况.结果:p16蛋白表达的阳性率分别为侵袭性鳞状细胞癌21.1%(4/19)、原位癌50%(15/30)、重度不典型增生83.3%(20/24)、中度不典型增生64.5%(20/31)、轻度不典型增生67.7%(20/31)、单纯增生80%(24/30)、正常组织60.7%(17/28).结论:p16蛋白表达的缺失可能与食管癌的发生发展有关.
