[/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. Stage 4 pancreatic cancer has the worst prognosis. Life expectancy is less than 4-5 months. In the case you are referring, this would be even lower. Liver and lung metastases with blood clots in leg veins (deep venous thrombosis) (DVT) In pancreatic cancer carry the worst prognosis. In such cases life expectancy is less than 3 months. So better to discuss end of life issues with him. </s>
