A Comparative Study of Neoadjuvant Chemotherapy Versus Upfront Radical Surgery for Upper Tract Urothelial Carcinoma
Evaluating the Application Value of Neoadjuvant Chemotherapy Compared to Upfront Surgery in Patients With Upper Tract Urothelial Carcinoma
Source: ClinicalTrials.gov · Last updated 4 Sept 2025
Brief summary (registry, in English)
This is a single-center, open-label, non-randomized controlled trial comparing the efficacy and safety of neoadjuvant chemotherapy (NAC) followed by radical surgery versus upfront radical surgery alone in patients with high-risk, non-metastatic upper tract urothelial carcinoma (UTUC). The study aims to answer the following key questions: Does NAC improve pathologic response rates (defined as downstaging to \<ypT2N0) compared to immediate surgery? What is the rate of pathologic complete response (pCR; ypT0N0) in the NAC group? How do the two treatment strategies compare in terms of overall survival, cancer-specific survival, and recurrence-free survival? What is the safety and tolerability profile of NAC using gemcitabine and cisplatin in this patient population? Eligible participants will be assigned to either the NAC-plus-surgery group or the surgery-only group based on clinical evaluation and patient preference. The study will also explore potential biomarkers (e.g., chromosomal instability in liquid biopsies) for predicting treatment response. Key Eligibility Criteria: Adults with histologically confirmed high-risk UTUC Clinical stage ≤N1 M0 Adequate renal function (GFR ≥45 mL/min) and ECOG performance status 0-1 Primary Outcome: Pathologic response rate (proportion of patients with \<ypT2N0)

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Concurrent participation in another interventional clinical trial at the time of enrollment.
Other illness
- Radiographic evidence of ≥cN2 lymph node disease or distant metastases (M1).
- History of invasive, lymph node-positive, or metastatic urothelial carcinoma within 2 years prior to enrollment, or history of invasive contralateral UTUC.
- History of a non-urothelial malignant tumor unless the patient has been disease-free for at least 1 year (exceptions include adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the cervix).
- Any other medical condition, comorbidity, or psychiatric illness that, in the investigator's judgment, would make the patient an unsuitable candidate for the study.
Other
- Presence of only a solitary kidney or cisplatin ineligibility.
- Pregnancy or lactation. Women and men of reproductive potential must agree to use effective contraception.
Who the study is looking for
- Histologically confirmed upper tract urothelial carcinoma (UTUC). For mixed histology, urothelial carcinoma must be the predominant component (≥50%).
- Clinically non-metastatic disease (cN≤1, M0) as determined by cross-sectional imaging (CT or MRI of chest/abdomen/pelvis).
- Planned treatment with radical nephroureterectomy (RNU).
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Adequate renal function, defined as glomerular filtration rate (GFR) ≥ 45 mL/min, making the patient a potential candidate for cisplatin-based neoadjuvant chemotherapy.
- Adequate organ and bone marrow function as determined by standard screening tests.
- Recovery from all reversible toxicities of any prior surgery.
- Age ≥ 18 years at the time of enrollment.
- Ability to understand the study and provide signed informed consent.
