CEA Setback?

Just got my latest blood results. I was hoping for some good news, but alas that was not to be. My CEA is again on the rise reaching 2499.0, which is another fifty point increase over last week. This is the second rise since starting on second line FOLFIRI chemo. I saw the same pattern during my first 5 rounds of FOLFOX chemotherapy with steady CEA increase, almost tripling in value over the 2.5 months. Later I found out that FOLFOX had no impact as far reducing my tumour size. If FOLFIRI behaves in the same way as the CEA markers indicate, I may be out of standard treatment options.

High CEA can also mean tumour death, so there is still some hope that Irinotecan is doing its job. The definitive answer will come on the 12th of April when I am due for the next CT scan. I am hoping to see at least some tumour shrinkage. The only positive sign, is that my liver function tests show a mild improvement and I have noticed a slight decrease in Nausea over the last 4 days.
