Desperately looking for Chemo Options for Endometrial AdenoCarcinoma

I have endometrial adenocarcinoma, stage 4, was 1st diaognised in july 2005, i had the radical hysteractomy, did 6 rounds of chemo- Adriamycin/ oncologist said the cancer was gone.....stopped the treatment and within 4 months it recurred in my pelvic,peritoneum and outside of the liver.....oncologist put me back on chemo regimen with single agent- Taxol....I have been taking taxol for almost 20 months....the last CT scan shows progression and thus the taxol is not working..

Now I dont know what other options I have....I am desperately looking for anyone who have gone through my situation, to write me for recommendations,
