Unlikely. Pancreatic cancer is amongst the nastiest cancers that have very poor survival rate stats to start with. Then when it spreads and becomes inoperable the writing is pretty much on the wall. . . then add on his advanced age and I suspect that he will already have seen his last Christmas.
I know someone that died of cancer a couple of years back (only age 50), it had spread to the lungs. The video they made from the hospital bed was quite harrowing - after being told they had 3 months to live.
They died just one week later. R.I.P.
