My dad has pancreatic cancer that spread to his liver. Chemo did not help. The cancer has spread more. How long can he live without further treatment?

Few months at best. Most pateints with metastatic pancreatic cnacer die within 6 months to 12 months. So given that he has liver metastases and already failed chemo, he may not live more than 1, 2 or 3 months. But it is not possible to predict it exactly.

Multiple factors. Multiple factors determine survival from here onwards including his baseline status (eg karnofsky performance scale), clinical status including breathing status, apetite, weight which would suggest median survival less than 60 days and supportive care and pain management. Usually oncologist will give you a best case scenario, in his case it could be 30 to 90 days. My prayers for your dad. Read more...
