New blood Test detects HPV-associated head, neck cancer 10 years early and with highest accuracy 4 years early

Good news! Cancer is history (soon)!

"Human papillomavirus (HPV) causes an estimated 70 percent of head and neck cancers in the U.S., making it the most common cancer caused by the virus. Yet unlike cervical cancers caused by HPV, there is no screening test for HPV-associated head and neck cancers.

In a new ... study, ... researchers show that a novel liquid biopsy tool they developed, called HPV-DeepSeek, can identify HPV-associated head and neck cancer up to 10 years before symptoms appear.  ..."

From the abstract:

"Purpose

Early detection of HPV-associated oropharyngeal cancer (HPV+OPSCC), the most common HPV cancer in the United States, could reduce disease-related morbidity and mortality, yet currently, there are no early detection tests. Circulating tumor HPV DNA (ctHPVDNA) is a sensitive and specific biomarker for HPV+OPSCC at diagnosis. It is unknown if ctHPVDNA is detectable prior to diagnosis, and thus it’s potential as an early detection test.

Methods

Plasma samples from the MassGeneralBrigham biobank collected 1.3-10.8 years prior to diagnosis from HPV+OPSCC patients (n = 28) and age- and sex-matched controls (n = 28) were blinded and run on a newly developed and validated multi-feature HPV whole genome sequencing liquid biopsy assay and a validated HPV antibody assay.

Results

ctHPVDNA results were positive in 22/28 pre-diagnostic samples from HPV+OPSCC cases (sensitivity 79%) with a maximum lead time of 7.8 years. ctHPVDNA results were negative in all controls (0/28 controls, 100% specificity). Diagnostic accuracy was highest within four years of cancer diagnosis and was higher than HPV Ab detection within the same time frame (p-value 0.004). Application of a machine learning model trained and tested on an independent cohort of 306 cases and controls increased the sensitivity of detection to 27/28 cases (overall sensitivity 96%) and the maximum lead time to 10.3 years.

Conclusions

Circulating tumor HPV DNA can be detected in the blood years prior to diagnosis with HPV+OPSCC, with high specificity, in a case-control cohort of 56 participants. ctHPVDNA detection alone, or in combination with previously identified serological biomarkers may be a feasible approach to early detection of HPV+OPSCC."
