Since we are talking about last-ditch efforts, I might add this paper reviewing different peptides which may fight cancers. I have no firsthand knowledge of these but the paper came up in something else I was reading (PNC-27 out of pure interest as someone who had cancer and is intrigued by peptides and their possibilities). Maybe there are some possibilities for your family they may be synergistic (or not obstructive) to what you are already trying.

In the paper they mention specifically for pancreatic cancers:
PNC-2 and PNC-7 |
in vitro |
Pancreatic cancer (MIA-PaCa) cells |
[109] |
|Cardiac natriuretic peptides|In vitro & in vivo|Pancreatic cancer (HPAC), renal carcinoma (SW156), breast adenocarcinoma (HCCI428), ovarian adenocarcinoma (NIHOVCAR-3), modularly thyroid carcinoma (TT), glioblastoma (LNZTA3WT4) and lung carcinoma (NCI-H1963) cells|
p16 In vitro Pancreatic cancer (AsPC-1 and BxPC-3) cells [166]
PNC-27 In vitro Cervical carcinoma (HeLa), colon cancer (SW1417 and H11299), breast cancer (MDA-MB-453 and MCF-7), osteosarcoma (SAOS2), leukaemia (K562), pancreatic cancer (MIA-PaCa-2) and melanoma (A-2058) cells. Rat k-ras-transformed pancreatic cancer (TUC-3) and transformed endothelial (E49) cells [214, 216, 217]
PNC-21 In vitro Cervical carcinoma (HeLa), colon cancer (SW1417 and H1299), breast cancer (MDA-MB-453), and osteosarcoma (SAOS2) cells. Rat k-ras-transformed pancreatic cancer (TUC-3) and transformed endothelial (E49) cells [214]
