目的:探讨高级别尿路上皮癌伴特殊亚型/特殊分化的形态特征及预后情况。方法:收集近年来诊断的25例特殊形态的高级别尿路上皮癌,总结其临床病理特征。结果:10例伴有鳞状分化(40%,最多);其次7例呈腺样分化(28%);5例局部伴有神经内分泌分...目的:探讨高级别尿路上皮癌伴特殊亚型/特殊分化的形态特征及预后情况。方法:收集近年来诊断的25例特殊形态的高级别尿路上皮癌,总结其临床病理特征。结果:10例伴有鳞状分化(40%,最多);其次7例呈腺样分化(28%);5例局部伴有神经内分泌分化(20%),其中2例呈小细胞癌的形态;4例部分区呈肉瘤样癌(16%,3例位于肾脏,1例膀胱);4例微乳头亚型(16%,均位于膀胱),均见脉管内癌栓;2例透明细胞型;共5例混合亚型(20%,4例均见腺样分化)。与普通的尿路上皮癌比较,伴有特殊亚型/特殊分化组的肿瘤最大径更大,癌栓多见,侵犯更深,总生存期缩短(38.9±7.6 vs 75.0±2.7个月)(均P<0.05)。2年总生存率(43.0±11.0)%,5年总生存率为(31.0±11.0)%。伴有腺样分化的患者随访期内无死亡患者,肉瘤亚型及微乳头亚型总生存期最短;女性、有远处转移、位于肾盂/肾盏均显示总生存时间缩短(均P<0.05)。有远处转移及肿瘤>4 cm是影响预后的独立因子。结论:特殊亚型预后差,更有侵袭性。微乳头亚型在膀胱多见,肉瘤样癌亚型在肾盂/肾盏更多见。展开更多
