Sorry to hear the diagnosis.  You might have her try pau d'arco tea.  Here is the cure zone testimonial of a person who cured their stomach and liver cancer with the pau d'arco tea:

You can find their original post on the above thread.

There are many sites which list the agents in pau d'arco as beneficial in killing cancer cells.  This one includes a reference to pancreatic cancer:

"But another chemical in pau d'arco, beta-lapachone, has been studied closely of late-and a number of recent patents have been filed on it. It has demonstrated in laboratory studies to have activities similar to lapachol (antimicrobial, antifungal, antiviral, antitumorous, antileukemic, and anti-inflammatory), with few side-effects. In one of these studies on beta-lapachone and other quinones in pau d'arco, researchers reported: "Because of their potent activity against the growth of human keratinocytes, some lapachol-derived compounds appear to be promising as effective antipsoriatic agents." In a 2002 U.S. patent, beta-lapachone was cited to have significant anticancerous activity against human cancer cell lines including: promyelocytic leukemia, prostate, malignant glioma, colon, hepatoma, breast, ovarian, pancreatic, multiple myeloma cell lines and drug-resistant cell lines. In yet another U.S. patent, beta-lapachone was cited with the in vivo ability to inhibit the growth of prostate tumors."

You might also look at Essiac tea.  (Some folks use both Essiac and pau d'arco teas at the same time.)  Here's a reference to Essiac curing liver and pancreatic cancer right here on cure zone:
