Hexalen Chemo & ovarian cancer

I recently went on a telephone support group and some of the ladies mentioned that they were on the pill, Hexalen for ovarian cancer. Has anyone been on this and if you have were there any side effects and did it stop the growth of the cancer. The ladies in the group said that while they were on Hexalen, they were NED for quite a while, some women were NED for a year.

Thanks.
