I've had a long run of treatment from Esophagas Cancer. Right now, the Oncologist has me taking ramcirumab. Good drug, but not friendly to take.

My question is whether or not ramcirumab works on your cancer until it no longer is there, or whether you take ramcirumab until you can't take it any more, and then it's downhill from there ? In other words can ramcirumab cause cancer to go into total recession?
