my husband is getting his 6 month PET scan today at Mayo after a second bout with OC. He had immunotherapy with chemo and then proton therapy at Mayo. He was told his was inoperable but Mayo said they had success with the above treatment mode.

A second opinion might be worth your while. His first opinion was to go home and die, the 2nd opinion had a solution. You never know.
