摘要 目的:观察 CD24在肾透明细胞癌多中心病灶及单结节病灶中的表达情况,探讨其在多中心病灶发生机制中的意义。方法收集完整的肾透明细胞癌根治术后标本,多中心病灶16例,单结节14例。检测CD24在肾透明细胞癌多中心病灶及单结节病灶中的表达情况。结果在肾透明细胞癌多中心病灶组CD24阳性表达率为100%;肾透明细胞癌单结节病灶组阳性表达率78.6%,CD24在两组的表达有显著性差异,P<0.01;16例多中心病灶中有15例原发肿瘤直径大于4 cm,占该组病例的93.8%;14例单结节组中有6例原发肿瘤直径大于4 cm,占该组病例的42.9%,两组差异有统计学意义,P<0.01;两组病例的病理分级对比发现多中心病灶组高分级(病理分级2~3级)为100%,单结节灶组高分级为85.7%,这两组在病理分级上差异无统计学意义,P>0.05。结论 CD24在肾透明细胞癌多中心病灶组表达明显高于单结节病灶组的表达,提示CD24高表达与肾透明细胞癌多中心病灶发生成正相关,多中心病灶发生可能是由肾内转移而来。
