Hi Denise,
My husband had Whipple surgery so I speak from the experience of caretaker.
Have you had radiation and 5 FU prior to Gemcitibine; radiation is considered the standard of care now. Also, since you are having a second opinion, I would suggest going to one of the institutions that is known to be outstanding in diagnosing and treating pc: M. D. Anderson in Houston, Johns Hopkins in Baltimore, Virginia Mason in Seattle or Columbia in NYC. (Dr. Robert Fine of Columbia is known to be especially excellent in the area of treatment.) These hospitals are well-known to be in the vanguard of research and treatment of pc. Mayo Clinic is a good hospital but is not known for its' treatment of pc.
I would also suggest your dropping in on the Johns Hopkins online pc support board; there are both patients and caregivers who are happy to share their considerable knowledge as well as listen when you need to vent and they will support you well. It is also mor active than this board. No doubt there is someone there who shares your exact history.
Good luck and Godspeed.
