Sponsor

Tianjin Medical University Second Hospital

Enrollment

150 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Lymph Node Dissection Upper Tract Urothelial Carcinoma

Summary

The goal of this clinical trial is to learn if adding a template lymph node dissection (TLND) to the standard surgery for upper tract urothelial cancer (UTUC) can improve patient survival and prevent the cancer from recurrence. The main questions it aims to answer are: Do patients who receive standard surgery with LND live longer without their cancer returning? Is adding LND safe, and how does it affect surgery-related complications? Researchers will compare the group receiving standard surgery plus LND to the group receiving standard surgery alone to see if adding LND is more effective. Participants will: Be randomly assigned to one of the two surgical groups. Undergo their assigned surgery and recover in the hospital. Attend regular follow-up visits for checkups and scans for 5 years to monitor for cancer recurrence, with the possibility of long-term follow-up extending to 10 years.

Eligibility

Min Age: 18 Years

Inclusion Criteria13

Signed written informed consent form (ICF). Age > 18 years at the time of ICF signing. Clinical diagnosis of unilateral Upper Tract Urothelial Carcinoma (UTUC) by imaging (enhanced CT or MRI) and/or ureteroscopic biopsy/urinary cytology, and scheduled to undergo Radical Nephroureterectomy (RNU).
Clinical assessment indicating that the tumor and regional lymph nodes are completely resectable, with at least one of the following high-risk features:
Locally advanced: Preoperative imaging assessed as cT2 stage or higher (i.e., tumor invades muscularis propria or deeper).
High-grade: Preoperative ureteroscopic biopsy pathology confirmed as high-grade urothelial carcinoma (or with squamous differentiation/sarcomatoid differentiation).
Moderate or severe hydronephrosis: Ipsilateral moderate or severe hydronephrosis due to tumor obstruction.
Large tumor size: Imaging measures maximum tumor diameter > 2 cm.
cN1: Imaging suggests regional lymph node short-axis diameter > 1 cm, and the investigator judges it to be resectable.
Presence of at least one measurable lesion according to RECIST v1.1 criteria. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Adequate organ function meeting the following requirements (without use of any blood components or colony-stimulating factors within 14 days):
Bone marrow function: Neutrophils ≥ 1,500/mm³, Platelets ≥ 100,000/mm³, Hemoglobin ≥ 9 g/dL (5.6 mmol/L).
Renal function: Serum creatinine ≤ 1.5 mg/dL and/or Creatinine clearance ≥ 60 mL/min.
Liver function: Total bilirubin ≤ 1.5 × ULN, AST \& ALT ≤ 1.5 × ULN. For women of childbearing potential (WOCBP): Must agree to use a highly effective medically approved contraceptive method during the treatment period and for 3 months after treatment ends. A negative serum or urine pregnancy test within 7 days before enrollment is required; must be non-lactating. For non-sterilized male patients: Must agree to use effective contraception with their partner during the treatment period and for 3 months after treatment ends.
Subject voluntarily joins the study, has good compliance, and agrees to undergo safety and survival follow-up.

Exclusion Criteria12

Previous receipt of any anti-tumor therapy for UTUC, including chemotherapy, radiotherapy, immunotherapy, or targeted therapy.
History or concurrent presence of muscle-invasive bladder urothelial carcinoma. Preoperative imaging assesses regional lymph nodes as unresectable: lymph nodes fused into a massive conglomerate, or fully encasing the abdominal aorta/inferior vena cava/pelvic vessels preventing safe separation.
Known bilateral UTUC or hereditary diseases that definitively increase the risk of contralateral upper tract tumors, such as Lynch Syndrome.
Diagnosis of other active malignancies within the past 5 years (except for adequately treated basal cell carcinoma, squamous cell carcinoma of the skin, or carcinoma in situ of the cervix which have been cured and show no recurrence within 5 years).
Presence of any active autoimmune disease or history of autoimmune disease. Current use of immunosuppressants for immunosuppressive purposes, continued within 2 weeks prior to enrollment.
Poorly controlled cardiac clinical symptoms or diseases. Coagulation abnormalities or bleeding tendency. Presence of specific active gastrointestinal conditions or uncontrolled tumor bleeding.
History of significant bleeding, hemoptysis, or thromboembolic events within specified timeframes.
Active infection or unexplained fever > 38.5°C during screening or before the first dose.
Occurrence of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 4 weeks prior to surgery.
History or current objective evidence of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, severely impaired pulmonary function, etc.
Congenital or acquired immunodeficiency. Participation in another clinical study within 1 month prior to enrollment, or potential receipt of other systemic anti-tumor therapy during the study period.
Known history of psychotropic drug abuse, alcohol abuse, or drug use. Inability or unwillingness to bear the out-of-pocket costs of examinations and treatments. Any other condition deemed by the investigator to make the subject unsuitable for participation.

Interventions

PROCEDURETemplate Lymph Node Dissection

A systematic and anatomic-based lymph node dissection performed during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). The dissection boundaries are strictly defined by a pre-specified template according to the primary tumor location: renal hilum+para-aortic (left hilar and paraaortic) or renal hilum+para-caval (right hilar, paracaval, and interaortocaval) for renal pelvis/upper ureter; extended to common/external iliac for mid-ureter; and pelvic (common, external, internal iliac, and obturator) for lower ureter. The goal is potential therapeutic benefit by removing nodal metastatic disease.

PROCEDURESelective Lymph Node Resection

A diagnostic procedure performed during radical nephroureterectomy (RNU). It does not involve a systematic template dissection. The surgeon will only remove intraoperatively identified suspicious and radiographic lymphadenopathy (\>1 cm in the short-axis diameter). The primary goal is pathological staging rather than therapeutic clearance of a nodal basin.
