An observational study in Chromophobe Renal Cell Carcinoma, Clear Cell Papillary Renal Tumor and Clear Cell Renal Cell Carcinoma, sponsored by Mayo Clinic. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-07-01.
Sponsored by Mayo Clinic · Observational
This study is being done to collect blood, tissue and urine samples to identify a novel high quality methylated DNA marker in patients with renal tumors.
PRIMARY OBJECTIVES:
I. In tissue, to discover and validate DNA methylation markers (MDMs) for detection of malignant renal and urothelial tumors.
II. In blood, to assess the accuracy of candidate MDMs from above for detection of malignant renal and urothelial tumors.
OUTLINE: This is an observational study.
Participants may undergo blood, urine, and tissue sample collection on study. Participants' medical records are also reviewed.
1,965 studies on the registry are indexed under Carcinoma, Renal Cell; 378 are open to participants now.
This study's enrollment of 589 is above the median of 146 across 360 observational studies indexed under Carcinoma, Renal Cell.

Identify novel methylated DNA markers in tissue for malignant renal and urothelial tumors
Assessed by the number of markers identified using unbiased whole methylome sequencing (RRBS). Top candidates will be validated in independent tissue. Potential markers will have relatively low background and a false discovery rate 20%.
