I often read the posts but don't post too often myself. I will start a new treatment of erbitux and CPT-11 next monday and would like anyone who has taken this combination to give me any info about side effects that you can. I have been on Folfox-6 and most recently Avastin and Folfiri (CPT-11, Leuco., and the 5-FU pump). However my Cea is rising again and my oncologist thinks that it is time to change. Thank you for any info you can provide.
