Place don't give up! He does not know what will happen. He can only give you an educated guess. Definitely get a second opinion, what you have at this point is sounds like it is NOT terminal - don't let it become that way. Chemo may hold it at bay but isn't considered a cure!

I have a friend who has a rare cancer - peritoneal - it was stage four - this cancer there is no cure for it, she went through treatment at a local hospital and went into remission it came back ithin 2 mos. second time out she had a reaction to the chemo, they switched her to an old one, the tumor grew and spread. Her dr. Said go home, you have maybe 6 mos. use your pain pills you'll need them. I told her to switch from our local hospital to the top center in Canada (an extra 20 minutes away) they put her on another chemo, and a trial drug, as of a month ago, there was a 27% shrinkage in her tumor.

They do not know ! Hugs.
