Hi there Hopefulandstrong,
My husband didn't have Folfox but Xelox as adjuvant chemo last Fall (following radiation for a lumbar met); it didn't work and a PET scan found a new tumor in his adrenal gland in January. He started Folfiri (with Avastin) mid-March and so far his CEA levels have been steadily dropping - 58, then 17, then 10. He'll probably get an MRI farily soon to see how much the tumor has shrunk (it was 5.3cm in March). But it's a good sign! Hopefully the same for you! Also, the side effects of Folfiri are a lot less intense than those of Xelox - a little tiredness, some heart burn (easily controlled with medication); hair loss, but that's temporary...
Good luck XXX
