An issue has been festering, for awhile. This entails men who have low PSA's and wind up one day with Bone Pain, and scans showing that the Pca reached the Bone, even though the PSA, was not considered dangerous and AS was the mode of treatment.
Also there are people like myself, who have a rare form of Ductal Pca, and all Ductal's kind of understate PSA, as it is estimated that 30% of what is left after initial treatment were non-PSA refractive Pca cells. And then when you look at men who have had what appears to be a durable remission, all of a sudden 6-10 years later they have a Biochemical relapse.
Add to this Micro-Metastasis, CTC---circulating Pca cells that have not landed. Many here have low or undetectable PSA's, with circulating Dormant Pca cells until they wake up.
Well wouldn't it be nice to know what is floating in our blood, instead of just relying on a PSA test. I am very interested, for I am told all my Pca, that is whatever is left, is in my blood, with no landings, yet. Well I want to know what is left. I could have 2 types left, Dormant, and Refractive Pca cells, that cannot yet land.
So in speaking with my Geneticist We have 2 methods of measuring cells left in the blood, and giving it a number per 7.5 ml of blood---and a table that predicts overall survival based on active cancer cells, and this table may not be accurate for Dormant cells. But anyway, How many do I have, or anyone here have.
The 2 methods are Nano Chip technology, where they put a micro sized chip in a vessel, that can capture cancer cells and measure them per 7.5 ml's--which is the standard for those doing testing. In this method, the cancer cell is bigger than the blood cell and gets captured and the rate of capture is measured. I know you are looking for less than 5 Cancer cells per 7.5 ml of blood for the result to be considered good for those with active Cancer cells.
The other method, that has a Medicare coding, can be obtained thru, CellSearch. You can go to CellSearchctc,com, and do some reading. Quest Labs is one laboratory that does the test. Blood is collected and sent overnight refrigerated, Through staining methods they can give you a count of Pca cells circulating per 7.5 ml's.
I contacted them and ask if they can measure Dormant Pca cells, they said they could not communicate on technical subjects, with patients, according to FDA rules[F--- the FDA],. So I p[an to have one of my Docs. contact, and if they can measure dormant cells, I will go forth with the test. I may be loaded with these, or it is possible we killed a bunch of my Pca. This CTC measuring, can very well offer patients certain lines of preferred treatment, instead of just relying on PSA, and scans when your PSA hits a specific number.
Anyway those interested in CTC's can go to the sight and discuss with their Docs. I am going to move on this for myself--for many reasons, some scientific to prove my ADT and Supplement Programs affect.
