My husband has just started his fourth cycle of CAPOX (oxaliplatin and capecitabine), having been diagnosed with Stage 3 bowel cancer in March. He had very low tumor markers when he started the chemotherapy in early May -- i.e. CEA and CEA 19-9 that are checked. After the first cycle / before the second cycle, his tumor markers increased slightly. They have continued to rise slightly between second and third; and, now the third and fourth cycle. His readings are now 3 for CEA and 15 for CA 9-9. I'm concerned, and while we are due to speak with the oncologist in a couple of weeks when my husband completes cycle 4, I am wondering if anyone in the Macmillan Cancer Support network has any experience with this sort of thing and can give insight. I will welcome anything, please. Thank you in advance!
