·临床研究与应用·高级别且淋巴结阴性上尿路尿路上皮癌患者的不同转移部位的预后因素分析高佳宁刘静雅王欢马克如丁德鑫摘要目的:探讨根治性肾输尿管切除术(radicalnephroureterectomy,RNU)后高级别且淋巴结阴性上尿路尿路上皮癌(uppertracturothelialcarcinoma,UTUC)患者的不同转移部位对预后的影响。方法:回顾性分析2010年2月至2020年12月355例哈尔滨医科大学附属肿瘤医院行RNU后病理证实为高级别且淋巴结阴性UTUC患者的临床资料,行预后相关因素的单因素及Cox比例风险回归模型多因素分析。结果:355例患者中77例(21.7%)出现转移,93例(26.1%)死亡,中位随访时间为45个月,中位年龄为67岁。肝脏、骨骼和多部位转移的中位生存时间(overallsurvival,OS)分别为6、6和5个月。Cox比例风险回归模型多因素分析显示,膀胱内复发(intravesicalrecurrence,IVR)、肿瘤大小≥2cm、肿瘤病理分期>T2期是患者转移的独立预测因素。结论:UTUC患者出现肝脏转移、骨转移和多部位转移相对较快,预后较差,而出现肺转移和淋巴结转移的预后相对较好。发生转移的晚期UTUC患者行同步放化疗、化疗联合免疫治疗的疗效优于未治疗、单独放疗和单独化疗者。关键词肿瘤上尿路尿路上皮癌膀胱转移预后doi:10.12354/j.issn.1000-8179.2023.20220937Prognosticfactorsatdifferentmetastaticsitesinhigh-gradenode-negativeuppertracturothelialcarcinomaJianingGao,JingyaLiu,HuanWang,KeruMa,DexinDingCorrespondenceto:DexinDing;E-mail:dingdexin19810328@163.comDepartmentofUrology,HarbinMedicalUniversityCancerHospital,Harbin150081,ChinaAbstractObjective:Toinvestigatetheeffectofdifferentmetastaticsitesontheprognosisofpatientswithhigh-gradenode-negativeup-pertracturothelialcarcinoma(UTUC)afterradicalnephroureterectomy(RNU).Methods:Theclinicaldataof355patientswithhigh-gradenode-negativeUTUCconfirmedbypathologyafterRNUinHarbinMedicalUniversityCancerHospitalfromFebruary2010toDecember2020wereretrospectivelyanalyzed.UnivariateandmultivariateanalysesofprognosticfactorswereperformedusingCoxproportionalhazardsre-gressionmodel.Results:Ofthe355patients,77(21.7%)hadmetastasisand93(26.1%)died.Themedianfollow-uptimewas45months,andthemedianagewas67years.Themedianoverallsurvival(OS)ofpatientswithliver,bo...
