Bazel--I'm new to this site. My mom is 77 years old and was diagnosed with a sizable tumor on the bile duct in Dec. 2006. Originally the head of oncology at NW Memorial in Chicago suggested resection for my mom. She was symptomatic but CT scans showed no signs of metatices. In Feb. 2007 she had surgery only to find that the cancer had spread to her abdomen and nodes. Due to complications with her incision and stents (infection), she was unable to start chemo until May. She began chemo then and was doing quite well. Many ups and downs, but carried on a semi normal life. A few weeks ago, however, even with lowered tumor markers, she began having frequent diarreha (not sure if chemo related). She's on Gemzar, like your dad 3 wks on 1 off. She also had increased stomach upset, acid stomach and fatigue. A recent hospital stay last week, after a night of vomitting, turned up no blockages, which is what they had expected. A few days on IV fluids and keeping down minimal food allowed her to come home. The same night she came home, she was vomitting again. She's been returning back and forth to the oncologist's office for IV fluids and this weekend has perked up. There are so many ups and downs it's difficult to know if she's really worsening. I too am the only one active in my mom's caregiving. I'm thankful for this site. Sometimes I think the doctors spare my mom the details on how this disease progresses. Hope you dad perks up too. I just keep praying for quality days, or hours or even minutes.
