The standard treatment is radical nephroureterectomy, which removes the kidney and ureter. Although this surgery can control the cancer, it permanently reduces kidney function.\n\nEndoscopic treatment can serve as a kidney-sparing approach for low-risk UTUC; however, in high-risk patients, the high rate of upper tract local recurrence after endoscopic treatment remains the primary failure pattern. This study aims to evaluate the efficacy and safety of radiotherapy-involved kidney-sparing treatment for UTUC.\n\nThe main questions this study aims to answer are: Can this multimodal kidney-sparing strategy reduce local recurrence of UTUC compared with endoscopic treatment alone? Participants in the kidney-sparing group will: Undergo endoscopic surgery to remove the tumor; Receive systemic therapy with disitamab vedotin and toripalimab; Receive targeted radiotherapy after surgery.\n\nParticipants will undergo regular follow-up visits, including imaging examinations and endoscopic evaluations, to monitor for recurrence or disease progression.\n\nThe results of this study may help determine whether a multimodal kidney-sparing treatment strategy could become a safe and effective option for selected patients with high-risk UTUC.",[24,25],"Upper Tract Urothelial Carcinoma Receiving Kidney-sparing Therapy","Upper Tract Urothelial Carcinoma",[27,28,29,30,31,32,33,34],"UTUC","Kidney-Sparing Surgery","Endoscopic Treatment","Disitamab Vedotin","Toripalimab","HER2-Targeted Therapy","Radiotherapy","Multimodal Therapy","NOT_YET_RECRUITING","2026-04-21",{"date":38,"type":39},"2026-04-24","ACTUAL",{"date":41,"type":20},"2026-04-01",{"date":43,"type":20},"2030-04-01",{"name":45,"class":46},"Peking University First Hospital","OTHER",1,{"id":49,"slug":50,"hasResults":11,"nctId":51,"briefTitle":52,"officialTitle":53,"acronym":4,"eligibilityCriteria":54,"healthyVolunteers":55,"sex":16,"minAge":17,"maxAge":56,"enrollmentInfo":57,"targetDuration":4,"studyType":21,"phases":4,"briefSummary":59,"conditions":60,"keywords":61,"overallStatus":64,"whyStopped":4,"lastUpdateSubmitDate":65,"lastUpdatePostDateStruct":66,"startDateStruct":68,"completionDateStruct":70,"leadSponsor":72,"locationsCount":47},"100531792","prognosis-of-patients-with-upper-tract-urothelial-carcinoma-receiving-kidney-sparing-therapy-100531792","NCT06204406","Prognosis of Patients With Upper Tract Urothelial Carcinoma Receiving Kidney-sparing Therapy","A Multicenter, Prospective, Observational Clinical Study to Evaluate the Prognosis of Patients With Upper Tract Urothelial Carcinoma Receiving Kidney-sparing Therapy","Minimum Age: 18 Years Maximum Age: 90 Years Sex: All Gender Based: No Accepts Healthy Volunteers: No\n\nCriteria:\n\nInclusion Criteria:\n\n1.

About two thirds of patients have muscle invasive disease at diagnosis. Those patients usually have poor prognosis. The 5 year cancer specific survival is \\\u003C50% for pT2\u002FT3 and \\\u003C10% for pT4. Radical nephroureterectomy is the standardized treatment for non-metastatic high risk UTUC. However, about half patients may suffer from impaired renal function after nephroureterectomy. On the other hand, kidney sparing surgery can avoid renal function impairment, but the therapy is only recommended for few patients with low-risk disease. The treatment for urothelial carcinoma has changed rapidly in the past few years. Immune checkpoint inhibitors and novel agents such as ADCs have shown promising therapeutic effect and were approved for patients with metastatic UTUC. Meanwhile, a recent study shows that patients with high-risk disease can also receive kidney sparing surgery without compromising cancer specific survival and overall survival. This prospective, observational study aims to evaluate the prognosis of contemporary kidney sparing surgery in patients with UTUC with or without perioperative therapy in the real world.",[24],[62,63],"kidney-sparing therapy","upper tract urothelial carcinoma","RECRUITING","2024-01-10",{"date":67,"type":39},"2024-01-12",{"date":69,"type":39},"2023-11-23",{"date":71,"type":20},"2028-12-31",{"name":73,"class":46},"RenJi Hospital"]
