My CEA has been all over the place. My oncologist has said that I am actually one of a small # of his patients that have a reliable CEA count. In other words, it goes up with disease & down with treatment. I really don't remember exactly what my #s were at the time of my DX, but it was something like 130, & it dropeed after my resection surgery & again after chemo, ending up in the nomal range. (4.6, I think.) ANYWHO, it started to slowly creep up several months after treatment & nothing showed up on a scan until November of '06, when TA DA! 22 lung mets!! I started back on chemo in December of '06 & in September of '07 my CEA was a whopping 470!!!
Well, my oncologist FREAKED OUT & we made some changes to my treatment. I am OH-SO-HAPPY to report that at last check (about a month ago) my CEA had plumetted back down to a lovely 56!!
Still high, but I'll take it!
