Please Advise. my Mom (75) is Dying i Think.

Here in india, information on this sort of topic is really not available and our doctors are'nt being very forthright. My mother was detected with ovarian cancer almost 2 years ago, underwent surgery, but they could not remove part of the tumor since it was sticking to the abdomen/rectum. She has been through 14/15 chemo sessions (taxol+carbo) - generally 1 every 6 weeks till december 04, and since then has been on oral medication for 2 cycles. For the last 5 weeks however her health has really deteriorated - she had no bowel control and lost significant weight. She now has a protruding stomach and her left leg is swollen all the way till the thigh. For the last 5 days she has been refusing food (we have her on a drip) and hasnt gotten out of bed, and is basically not even talking. It's almost like she is waiting to die. Can someone help me? What should I expect next? At a stage like this, how long before she finally dies and finds peace? Can I do ANYTHING to make things better for her? Please respond. I shall be greatful for your help and advice. And do pray for her to find heaven soon please.
