Int J Urol:上尿路上皮癌根治术后对侧上尿路复发预测因素调查

2021-11-09 AlexYang MedSci原创

探讨了上尿路癌根治性肾切除术后对侧上尿路复发的关键预测因素。

尿道癌是一种源于尿道上皮的恶性肿瘤疾病,可能涉及下尿路(膀胱、前列腺和尿道)和上尿路(肾盏、肾盂和输尿管)。UTUC约占所有尿路上皮癌的5%。RNU与膀胱袖口状切除术是局部UTUC的标准治疗方法。据已发表的文献,这两种手术的术后复发率很高,主要包括膀胱复发、局部复发和CUTR。由于膀胱复发很常见,因此已有广泛研究。

近期,《Int J Urol》杂志上发表了一篇文章,探讨了上尿路癌根治性肾切除术后对侧上尿路复发的关键预测因素

在2001年1月至2015年12月期间,研究人员将548名在单一机构接受根治性肾切除术的上尿路上皮癌患者纳入了研究。他们调查了一些临床病理特征和结果。关键的终点是根治性肾切除术后的对侧上尿路复发的诊断情况。

在这548名患者中,中位年龄为68岁(范围24-93岁),RNU后的中位随访时间为41个月(范围8-191个月),男性患者有237名(43.2%)。其中,328名患者(59.9%)的年龄大于65岁,389名患者(71%)从不吸烟。128名患者(23.4%)的术前肾功能不佳(eGFR<30 mL/ min/1.73 m2)。共有71名患者(13%)有尿毒症病史,其中7名患者(9.9%)曾接受过肾脏移植手术。212名患者(38.7%)存在肿瘤多灶性。CUTR 在28名患者(5.1%)中发生。

RNU和CUTR之间的中位时间间隔为15.4个月(范围3.4- 52.4个月)。总生存率和UTUC特异性生存率不受CUTR的影响。总共有13个临床病理参数确定为CUTR的重要预测因素。在单变量分析中,eGFR<30(HR 3.23,P=0.002)和肿瘤多灶性(HR 2.30,P=0.029)显示出统计学显著性。Cox回归模型多变量分析表明,eGFR<30(HR 3.08,P=0.003) 和肿瘤多灶性(HR 2.16,P=0.043)仍是CUTR的重要预测因素。

预测CUTR临床病理参数的单变量和多变量分析

综上所述,术前估计肾小球滤过率<30和肿瘤多灶性是上尿路癌根治性肾切除术后对侧上尿路复发的重要预测因素
