Medical Forum / Diseases and Disorders / Cancer / December 2007CEA cancer test question
Hi there all. On September 2006 I was diagnosed colon-cancer positive after a colonoscopy. Also on that month, I had a CEA test reading of 0.4. In December of 2006 another CEA test reading was 0.7. And last November (2007) another CEA test reading, at a different lab, was 0.7. Also in December (2007) I underwent an MRI test, which indicated that the cancer tumor was, externally, about the same size it was in September of 2006, or about 4 centimeters. But the MRI test also indicated that the tumor has "disrupted" (penetrated) the intestine wall. My question: does the CEA test reflect colon tumor growth towards the inside, such as the "wall disruption" indicated by the MRI test? If the answer is yes, given the fact that the CEA reading has shown almost no change since September 2006 to last month, could this be interpreted to mean that the penetration revealed by the MRI test was already present in September of 2006, when the initial CEA was taken? Thank you all..! I don't understand. Wouldn't you have had the tumor surgically removed? Mel > Hi there all. On September 2006 I was diagnosed colon-cancer > positive after a colonoscopy.

The test should alreays be done at the same lab. http://www.medicinenet.com/carcinoembryonic_antigen/article.htm Steph may have a comment, so watch for it. Keep in touch and let us know what an oncologist says. He or she will want to see the operative report and pathology report. J > Hi there all.

I missed the fact that he had not had the surgery. He was here Dec/06 but never mentioned he had cancer. J > No, CEA is a very blunt test.

Let me restate it: If in December of 2006 CEA reading was 0.7 and in November of 2007 it was still 0.7, could that be interpreted as to mean that the "disruption" or penetration of the intestine wall identified in an MRI test a couple of weeks back (December of 2007) did NOT occur this year, but was already present last December 2006? Because, if CEA, as you say, shows growth trends, then it seems to me that it "should" have showed the penetration, if it had occurred after December of 2006. In fact, "one" of the doctors I have consulted (a gastroenterologist) agrees, but another one (radiologist) does not. Hence my present confusion.

Maybe you missed some important words in what Steph wrote? "CEA is a very blunt test. It shows general growth trends in some tumours, that's all.

Let's talk, before you rush off to an oncologist. What's the size of the tumor, the location in the colon and what surgery was recommended, please? J |
