A kidney cancer prediction model to guide treatment decisions, including for patients with tumor thrombus

Emulated-target Trial for Guiding Stratified Treatment for Renal Cell Carcinoma With Venous Tumor Thrombus

Observational Peking University Third Hospital · NCT07117227

This project will test whether a new prediction model can guide treatment choices to improve survival for adults with renal cell carcinoma, including those with venous tumor thrombus.

What this trial studies

This is a single-center observational analysis using real-world data from about 4,700 RCC patients treated at Peking University Third Hospital from 2012–2026. Researchers will develop and validate a prognostic model for RCC (including a venous tumor thrombus subgroup), compare its discrimination and calibration against existing published models, and examine model stability. An emulated target trial framework will be used to compare outcomes of risk-stratified adjuvant treatment (high/medium/low risk) versus non-stratified treatment, with survival and health-economic endpoints. The cohort includes adults 18–80 years who underwent radical or partial nephrectomy and excludes patients with distant metastasis at baseline or severely incomplete records.

Who should consider this trial

Good fit: Adults aged 18–80 with primary renal cell carcinoma who underwent radical or nephron-sparing nephrectomy and have complete clinical data are ideal candidates.

Not a fit: Patients with distant metastasis at baseline, a history of other malignancies, severely missing clinical records, or who discontinue adjuvant treatment early are excluded and unlikely to benefit.

Why it matters

Potential benefit: If successful, the model could help doctors personalize adjuvant treatment so higher-risk patients get more aggressive therapy while lower-risk patients avoid unnecessary treatment.

How similar studies have performed: Several published RCC prognostic models exist and have shown variable predictive performance, but applying an emulated target trial to test model-guided treatment in RCC is relatively novel.
