Pancreatic cancer has a terrible prognosis as it is, and Stage IV (metastasis) makes that worse. If the cancer makes it into the bloodstream, and isn't wiped out completely by the chemo (cancer cells have an evolutionary dynamic like antibiotic resistance; this is why chemo drugs can stop working before they kill all the cancer) it's very likely that it's a chronic illness and terminal within 5 years: often much less.
