NavDX positive test

UPDATE: on mets from my Head and Neck HPV SCC P16. After 7 months of the NavDX blood test going up and not showing up on a PET scan. It showed up with a 1.1cm tumor on my left lung. They removed the Tumor on Oct 14th in Virginia Mason hospital in Seattle. I got another NavDX blood test back this week still showing a positive level of 18. This is from a high before surgery of 210. My Tumor pathology report came back with PERTINENT POSITIVE FINDINGS: PD-L1 expression for Keytruda (CPS=60)….. I start my Keytruda next week and every 6 weeks for two years.I will be doing the NavDX every 3 months along with a PET scan. I wish you all a happy Thanksgiving and a wonderful holiday season……..Bill…….P.S. my Ct guided biopsy of the tumor originally showed negative for PD-L1. It just shows you how much more info you get from the tumor…..

Newby here…….Thanks to everyone for sharing their experiences as there is a wealth of info in this thread. Having gone thru most of the thread here I noticed the number/scoring of the NavDx test is considerably lower compared to the results I have received. My oncologist has been ordering the NavDx tests for me since 10/2023 and my numbers have ranged from a low of 257 to a high of 46000. I am currently in METS stage (liver and bone). Originally diagnosed BOT HPV P16+ in 2016, and Prostate cancer 2020. BOT treatment was chemoradiation, and prostate was surgically removed. PSA tests consistently less than 0.01.

That gives me hope OhNoltsMe. I’m going through my second type of chemo treatment (first one carboplatin, 5 flourosil, keytruda was unsuccessful) since METS and my recent NavDx score is 753. Scans show lesions in liver shrank from 3cm down to .6 cm. I’m in year 8 of this marathon.
