Hi and welcome to HCM,thank you for your query.
these are obviously metastases to pancreas
and lungs and this is very bad sign. Unfortunately such tumors are commonly inoperable and only chemoth may help. of course,it is hard to predict anything but he needs combined surgical and chemoth treatment to remove all signs of tumors intraabdominaly. If this cant be achieved then paliative treatment is the only option.
Wish you good health. Regards.
