# Urine based circulating tumor DNA analysis

> **NIH NIH R37** · INDIANA UNIVERSITY INDIANAPOLIS · 2022 · $73,534

## Abstract

Urine is an underappreciated source for systemic circulating tumor DNA in patients with non-genitourinary
cancers. Based on recent data suggesting that blood-based HPV DNA testing is useful for disease monitoring
in HPV positive oropharynx cancer patients, we identified non-metastatic HPV positive oropharyngeal cancer
patients as an excellent model system to examine the potential of urine-based transrenal DNA analysis. Our
preliminary data suggests that our newly developed urine-based HPV test could have biomarker performances
comparing favorably to blood-based HPV testing. The specific objectives of this application are to establish that
urine is a suitable source for HPV DNA in non- metastatic HPV positive oropharynx cancer patients, and that
at-home urine based molecular testing is feasible for these patients. Specifically, we will compare sensitivity
and specificity of pre-therapy urine-based HPV testing to tissue gold standard testing in a cohort of newly
diagnosed non-metastatic oropharyngeal cancer patients. Recurrence detection lead time of urine-based HPV
testing will be compared to clinical routine care in the same cohort after curative intent treatment. Controls will
include blood-based HPV testing, pharyngeal swab-based HPV testing and blood based personalized ctDNA
sequencing panel testing. Additional control cohorts will include cervical and anal cancer patients as well as
cancer-free patients with recently diagnosed oncogenic HPV infections. Using in vivo fluorescence imaging
techniques, we will generate fundamental knowledge on renal handling of cell free DNA and determine the
impact of chronic kidney disease and other patient, disease and iatrogenic factors on cell free DNA excretion.
