My previous treatment of oxaliplatin, bevacizumab and flourocil for stage 4 CRC has stopped working and now I am being given panitumumab alone. My previous oncologist said I should not be taking antioxidents with bevacizumab, but this one (a few of them alternate at my hospital), didn't seem to know anything about whether antioxidents or cannabinoids would interfere with panitumumab. Does anyone know anything about this?
