NavDx is a blood test that aids in the detection and monitoring of HPV-driven head and neck cancers. It specifically detects circulating tumor-tissue modified HPV (TTMV®) DNA fragments in the bloodstream. This test is used to assess treatment response, detect recurrences. It is used for head and neck cancer, specifically HPV-driven oropharyngeal squamous cell carcinoma (OPSCC), has demonstrated high accuracy. It boasts a specificity of ≥97% and a sensitivity of ≥89%. Furthermore, it shows a positive predictive value (PPV) of ≥95% for cancer recurrence when a patient has one positive test result. NavDx also demonstrates a high negative predictive value (NPV) of ≥98% when TTMV-HPV DNA remains undetectable, indicating no recurrence. In cases of clinically indeterminate findings, NavDx has shown a 98% accuracy rate in resolving
I copied and pasted the above, but as you can see a very accurate test of HPV cancer activity. My first blood test was positive and The last 4 were negative after my TORS surgery (which showed negative margins). Also, I received my blood test results within a few days. The NavDx test is another tool in the toolbox to help them diagnosis cancer activity. They also use PET /CT scans to look for activity. With the trend towards De-escalation I would think yes this would be overkill. However, It is a call only you can make. Most of the folks who comment here have been through it and It is not pleasant but we are still here. I would demand the NavDx to help guide you in your decision. Lean on your Faith! God Speed
