ASCO2022:除癌症分级与分期外,这些因素也会影响上尿路上皮癌患者的预后

2022-06-02 MedSci原创 MedSci原创

在这项大规模的、长期的UTUC患者随访中研究人员进一步确定了除分级和分期外影响预后的几个预后因素。

上尿路上皮癌(UTUC)是一种罕见的异质性疾病,约占上皮癌的5-10%。虽然肿瘤分级和分期是已知的预后因素,但有关影响UTUC手术患者预后的其他因素的数据很少。为此,来自美国克利夫兰诊所的学者研究了各种临床因素和治疗对UTUC预后的影响,结果发表在ASCO2022大会上。

这是一项单一机构的回顾性研究,研究对象为2000年1月至2020年12月期间607名接受手术(肾输尿管切除术(NU)或输尿管切除术(U))的UTUC患者。研究了人口统计学特征、临床病理特征、肿瘤位置、术前中性粒细胞-淋巴细胞比率(NLR)和白蛋白-球蛋白比率(AGR)以及使用新辅助或辅助化疗对总生存期(OS)和无复发生存期(RFS)的影响。

结果共纳入607例患者,其中401例(66.06%)为男性,355例(58.48%)>70岁。其中,肾盂UTC232例(38.22%),输尿管UTC 242例(39.87%),两者均有133例(21.91%)。542例(89.29%)进行了根治性NU, 65例(10.71%)进行了局灶性性U术;328例(54.04%)诊断为肌肉浸润性UC (MIUC) (> / = pT2), 276例(45.47%)诊断为非MIUC (< / = pT2)。51例(8.4%)淋巴结阳性(N+)。163例(26.85%)发现淋巴血管浸润(LVI), 163例(26.85%)发现原位癌(CIS)。手术切缘阳性92例(15.16%)。

NLR中位截止值为3.25,AGR中位截止值为1.25。44例(7.2%)接受新辅助化疗,49例(8%)接受辅助化疗。216例(35.58%)患者发生了肿瘤复发,其中65%发生在尿路上皮,35%发生在非尿路上皮。中位随访35.2 mos,中位OS 82.69 mos, 5年OS率为60%;中位RFS为29.47 mos, 5年RFS率为40%。高级别、年龄≥ 70岁、高NLR、低AGR、存在LVI、切缘阳性、CIS、MIUC、N+疾病与较差的预后相关。只有肾盂受累的患者OS较好。

在这项大规模的、长期的UTUC患者随访中研究人员进一步确定了除分级和分期外影响预后的几个预后因素。
