Just getting caught up on postings here. Sorry it took so long to reply.
When I had my surgery, I spent 5 days in the hospital and actually did very well with recovery. I have about a 12" scar across my abdomen which is no where as noticable as it was. Just a little pink. I developed an abscess about a week after surgery and had a drain put in for a week, but handled that well too. I lost about 30 pounds overall due to not being able to eat the "bigger" meals that I was accustomed to. AND I actually needed to lose weight too. However, I gained it back when I began chemo.
More than a year later, I do feel like there isn't anything wrong with me, although the chemotherapy did not work. I know that's not the same for everyone, so don't feel nervous about that. Chemo may work for your sister even though it didn't for me. Looking back, my surgeons made errors in judgement that probably caused my cancer to return. The best chance though is that your sister had surgery to begin with. That is at least the first fight to getting this cancer.
The chemos that I was on was first Gemcitabine with Cisplatin; then Oxaliplatin with Xeloda, and finally a clinical trial of Irinotecan. I tolerated all of these very, very well compared to what I've heard others say about them. Whether that means my age was a factor, or probably why they weren't working, I don't know. I'm in the process of finding another doctor to seek other treatment options. Don't give up....don't ever give up. There is always something new popping up out there.
I wish you both the best.
