After reading the article, seems that they are just beginning to refine how this test can be used. The senior study author states that they have more work to do: "we are planning further studies to precisely define the role of monitoring CTCs in women with metastatic disease.�
The basic guideline they are using of 5 or more CTCs (circulating tumor cells) per 7.5ml has more to do with getting that number down to improve survival in patients. Seems they can use this as a guide to step up treatment in patients with that higher number to improve their chances, as well as a tool to see what is working.
I am JAZZED to think that I can go in and get a test other than the usual tumor markers to determine if more testing/scans are needed to see if this darned disease is again on the march!
