摘要 目的探讨淋巴血管浸润(lymphovascular invasion,LVI)在伴有鳞状分化的pT1期膀胱尿路上皮癌中的预后意义。方法回顾性分析105例伴有鳞状分化的pT1期尿路上皮癌患者的临床及病理资料,按照是否存在LVI分为2组,比较LVI阳性与LVI阴性患者病理特征,并通过单变量和多变量Cox回归分析影响膀胱尿路上皮癌肿瘤特异性生存率(cancer specific survival,CSS)的因素。结果105例患者中,29例(27.6%)出现LVI。5年肿瘤特异性生存率(cancer specific survival,CSS)在LVI阴性患者中为86.8%,LVI阳性患者中为51.7%(P<0.001)。Cox单变量分析结果显示肿瘤大小、复发率和LVI是影响CSS预后的因素,在多变量分析中,肿瘤大小和LVI对CSS影响显著。在复发的LVI阳性患者中,TURBT的5年CSS低于RC(P<0.05)。结论对pT1膀胱尿路上皮癌伴鳞状分化患者,LVI与预后密切相关,LVI阳性患者死亡风险升高。pT1期膀胱癌伴鳞状分化尤其是合并LVI的患者应尽早行行根治性膀胱切除术,以提高患者生存率。
