Chromophobe Renal Cell Carcinoma, Clear-cell Renal Cell Carcinoma, Kidney Cancer, Papillary Renal Cell Carcinoma, Renal Cell Carcinoma
Conditions
Brief summary
This is a correlative (lab-based) study aiming to identify protein markers in urine extracellular vesicles (EVs) that can be used to develop non-invasive molecular tests for patients with renal cell carcinoma (RCC). Aim 1 will use urine collected previously in biorepository. Aim 2 will prospectively collect blood specimens pre and post nephrectomy.
Interventions
EV isolation and mass spectrometry.
Blood samples collected pre- and post-nephrectomy

Eligibility
Inclusion criteria
* Urine sample in existing biorepository * High-risk renal cell carcinoma (RCC) per American Urological Association (AUA) guidelines * Scheduled to undergo nephrectomy
Exclusion criteria
* Does not meet inclusion criteria
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Differentiate tumor-derived extracellular vesicle (tdEV) surface proteins expressed in benign vs malignant renal tumors | Baseline | Differential protein expression analysis will be performed on stored urine samples from a biorepository to identify tdEV proteins in each renal cell carcinoma (RCC) subtype (clear-cell, papillary, and chromophobe) versus benign. |
| Prediction of metastasis after surgery | Perioperative (pre- and post-nephrectomy), | Blood samples will be collected pre-and post-nephrectomy to asses for tdEV levels which will be correlated with clinicopathological features to test whether tdEV levels can be used to better predict likelihood of metastasis in patients undergoing curative-intent radical nephrectomy. |
