New information is always becoming available and impacts physician thinking. On the other hand old habits die slowly and some doctors don't stay up to date. I find it useful to ask the oncologist 3 simple questions which they should be able to answer. 1. What is the goal of treatment? Is it to cure the cancer, prolong survival, reduce symptoms?
2. How does the proposed treatment compare to not receiving treatment or other potential treatments? Your doctor should be able to quantify how much the proposed therapy will improve your outcome.
3. What is the role of clinical trials? Can participation in a trial offer a better outcome than the recommended treatment?

Remember it's your decision...but treatment of early stage pancreatic cancer does improve outcomes. https://news.cancerconnect.com/pancreatic-cancer/treatment-of-stages-i-ii-pancreatic-cancer-a19I-OV9y0u1kDmwPBp4lA
