Hi -
I may be wrong but I was told that MOST gynecological oncologists are surgeons - and do the surgery with the de-bulking - and that a medical oncologist is needed for follow-up and treatment. That was the way I went. My gynecological oncologist dis consult with my medical oncologist though ( regarding any further surgeries, biopsies, etc).
Hope this helped some. Good luck to you.
