Hello and welcome to the site, so sorry you had to find us but glad you did under the circumstances. Everyone I've experienced on the site is wonderful - very caring and helpful.
I am 48 years old and was diagnosed in July 2009 and started gemcitabine and oxaliplatin. It worked well and shrunk the primary tumor slightly. I had to discontinue the oxaliplatin in February 2010 as it will cause peripheral neuropathy in the hands and feet after 4-6 months. If one doesn't d/c it, the neuropathy can become permanent. Mine has improved and my oncologists warned me that it may take a year to completely go away.
I am still on gemcitabine and now capecitabine (Xeloda), an oral form of 5-FU. I have tolerated this well so far.
Tell your mother to hang in there and keep fighting. I know how tough this battle can be. Attitude makes a huge difference and makes the journey easier. Hang in there and lean on others at this site for assistance and support!
