Splenectomy might be really dangerous because with the cancer spread there,
there  may be major risk of major bleeding. Quite frankly, my guess is that
the cancer has spread beyound her stomach and spleen. Unfortunately, I doubt
there is much that can be done to cure her. The only things that can be done
are to make her final time better. Anyway, without further information,
anything we say will really be a guess.

I think you need to talk with the family members who are the ones who have
talked most to the doctors and understand what has happened (of course, I am
jump to the conclusion that you didn't do this). In the US, usually one or a
few people are the ones who talk most with the doctor (in this case, one or
a few of her kids along with her husband, if the earth is still blessed with
him would be most liekly), and those people talk with the rest of the
family. I suspect it is similar in Finland.

After do this, you may wish to get a second opinion, either from another
hospital in Finland or one in Europe or North America.

There are many excellent hospitals in Europe and the US (including Stanford,
Johns Hopkins, Harvard, NYU, Memorial Sloan Kettering, Penn, Fox Chase and
Duke in the US). And you can get a second opinion in some cases by sending
any CT, MRI, etc., scans as well as progress notes to the other hospital,
although she might be required to do there as well (for obvious reasons).

Anyway, my thoughts and prayers are with you.
