Hi there.
Thank you for your question.
I will be helping you out with your queries.
In the first few weeks of chemotherapy CEA can rise and this actually indicates that you are responding to chemotherapy.

Ok thx .so after round 1 it jumped to 80 and was 65 before chemo .if after round 2 it goes to 55, would you count the drop from the original 65 or the 80?

Yes I would count that as a drop and that you are responding to chemotherapy.

So what can responding actually mean ? What will happen to the metastses ? He has liver mets and 4 peritoneal mets which are 2mm

The mets may shrink.
Liver and peritoneal mets also may shrink as well.
Please rate me before we proceed.
