CEA: HYPOTHYROIDISM MAY CAUSE MILD ELVATIONS

lovetodance1

I WANT TO HEAR ABOUT CASES WHERE CEA FLUCTUATED WITHIN NORMAL RANGE. MY PREOP CEA WAS ONLY .7 (YES WITH TUMOR INSIDE) AND STAYED LIKE THAT UNTIL AFTER 6 WKS POST CHEMO. IT BOUNCED 2.7, 3.7, 3.6, 5.4, 4.7, 6, 5.4, 4.7, 3.9 ALL IN 2011.MY LAB UPPER NORMAL IS 5.

LAST YEAR STAYED BETWEEN 2.6 AND 2.9.  CA 15.3 HAS ALWAYS BEEN LOW AT 8 OR SO. THE TRICK WAS THAT APPARENTLY CHEMO AFFECTED MY THYORID AND MY SECOND PET IN 2011 WAS GOOD BUT SHOWED THYROIDITIS. THIS WAS WHEN THE CEA WENT UP BUT MY THYROID WAS NOT CHECKED UNTIL OCTOBER AND MY TSH WAS 10(HIGH). BEGAN SYNTHYROID AND CEA DROPPED TO LESS THAN 3 IN JAN. 2012 AND STAYED LKE THAT FOR WHOLE YEAR. MY ONC WAS NOT WORRIED AND BLAIMED ON TAMOXIFEN. MY LAST PET WAS 9 MONTHS AGO AN YEAR POST INCREASE AND CLEAR. I DO NOT GET WH IS NOT YET 1 OR SO WITH 4 NEGATIVE PET SCANS IN TOTAL. TUMOR MARKERS ARE A PAIN. I WONDER IF CEA IS NOT A MARKER FOR ME. SOME ONCS SAY IT SHOULD NOT BE USE FOR BC. I'LL LIKE TO HEAR COMMENTS. THANKS.
