Re: What is considered the usual frequency of CEA test

[Guest guest]

For colorectal cancer, it is recommended that carcinoembryonic antigen (CEA)

levels be measured preoperatively if it would change surgical management. It

is recommended that CEA levels be monitored every 2 to 3 months for 32

years, if resection of liver metastasis would be clinically indicated. The data

are insufficient to recommend the routine use of lipid-associated sialic acid

(LASA), CA 19-9, DNA index, DNA flow cytometric proliferation analysis, p53

tumor suppressor gene, and ras oncogene. For breast cancer, estrogen receptor

and progesterone receptor are recommended to be measured on every primary

specimen, but on subsequent specimens only if it would lead to a change in

management. The data are insufficient to recommend the routine use of DNA

index,

DNA flow cytometric proliferation analysis, CA 15-3, CEA, c-erbB-2, p53 or

cathepsin-D. In the absence of readily measurable disease, CA 15-3 and CEA

levels

can be used to document treatment failure. New markers and new evidence will

be evaluated by annual update of these guidelines.

My CEA had been running around 6 something when I was having it tested every

three months. Since there was not much changes they were not concerned till my

pet/ct showed a cancer mass and my CEA jumped to 12.1. I had surgery 1 month ago

and the good news is the mass was scar tissue and not cancer again. I forgot to

ask the surgeon why it would have jumped to 12.1 and wonder if they took it

after surgery or will now. That one mass of scar tissue showed up in 3 Pet

scans! I know my smoking makes mine higher but still don't know why it would

double. Still working on stopping smoking but it is not easy. I will be asking

my regular Dr for the Zyban he has been trying to give me a prescription for.

What is considered the usual frequency of CEA

test

Ive searched for but cannot find anything which gives the usual testing

frequency of CEA

levels which is the colon cancer tumor marker found in the blood.

I think I have hit the angry stage because I cant help wondering that if this

test had been

performed before every chemo session the rise in Mikes CEA levels would have

been noticed

earlier. Its as if he suffered the last 6 and all those side effects for

nothing.

Mikes CEA was 190 before session 1, 50 after session 6 and 243 after session

12 so you can

understand why I am angry and uncertain.

Mike is starting Oxaliplatin and Erbitux on Monday and I want to find some

reference to take

to Mikes Onc which might indicate more frequent testing. On the other hand

maybe its the

norm but need to know.
