摘要 目的:探讨膀胱原发单纯性小细胞癌(small cell carcinoma,SmCC)的临床病理学特征和预后。方法:收集2005年1月至2019年4月青岛大学附属医院、海军第九七一医院及青岛市市立医院诊断膀胱原发单纯性SmCC 15例,采用HE、免疫组织化学染色进行组织形态学、免疫表型观察,并与同期诊断的28例浸润性高级别尿路上皮癌进行预后比较。结果:15例SmCC中,男性12例,女性3例,年龄54~86岁。13例表现为肉眼血尿,1例腰部疼痛,1例体检发现。8例行膀胱根治性切除(5例)或膀胱部分切除术(3例),5例经尿道膀胱肿瘤电切术,2例行活检术。瘤组织镜下呈片状或弥漫排列,细胞小至中等大,核深染,染色质细腻,核仁不明显,核分裂象易见。6例间质脉管内可见癌栓,3例手术时有盆腔淋巴结转移。瘤细胞对CD56、突触素、嗜铬粒素A(CgA)、广谱细胞角蛋白(CKpan)、细胞角蛋白(CK)7、甲状腺转录因子(TTF)1、p16的阳性表达比例分别为13/13、15/15、10/14、11/11、6/11、9/12和9/9。15例SmCC中13例获得随访,中位生存期为23个月,28例浸润性高级别尿路上皮癌中位生存期为39个月。结论:膀胱原发性SmCC通常分期高,易转移,预后差。p16阳性表达对膀胱SmCC的诊断可能具有潜在应用价值。
