Hello, my grandfather was diagnosed with stage IV-b pancreatic cancer with 9 confirmed cancer spots on his liver about 3 weeks ago. He started a combination of chemotheropies today (not sure which ones exactly) and is apart of a clinical trial using BBI608. He has also been to be upgraded to morphine for the pain as other drugs were not helping. My main concern is I feel his current doctor is misleading them into believing this can be sent into remission and beat. From all the research I have done it seems he is in a worst case possible scenario. I know the best thing any of us can do for him right now is stay possitive and I understand that, but I also think a patient should be fully informed of their situation. My question is basically how long would you give a person to live given this information? Most of my family thinks he can still make it another 5-15 years but I know thats highly unlikely and I don t want my family to be blindsided by him passing in the next 3-6 months. Any information would be greatly appreciated, I just want to know if I m misunderstanding something or if this doctors possitive attitude has unintentionally given my family a sense of false hope. Thank you for your time. Randall

Thanks for your question on Chat Doctor. I can understand your situation and problem. Stage 4B pancreatic cancer is very notorious in spread as well as prognosis. Life expectancy is less than 2 years. With hepatic metastases it will further decline to less than 1 year. And treating doctor is giving him palliative care, which is right thing. But you have to ask prognosis in detail. And by no means life expectancy is 10-15 years.
