Any experience with navelbine chemo?

Hey all, its been a long time since I have posted on here. I still read all of your posts frequently.

As a recap-my mother was diagnosed with stage IV ovarian in january 2010 at 57 years old. She has had some tremendous battle!
She has never had a debulking surgery since the docs say that it is too advanced.... but none of her major organs are affected. She has undergone fluid drainage from around her lungs and just recently had fluid drained from her abdominal cavity. She is going to start her 3rd type of chemo this week,navelbine. Any experience with this??? Her first chemo was taxol/carbo mix, then they switched to topotecan and that was not too helpful.

Thanks in advance for your info!
