Hi All. I have stage 3 ovarian cancer. I had a full hysterectomy, part of my colon removed and part of my stomach lining. I started chemo and my CA125 was going down pretty fast and I was so excited. On round 4 my doctor told me my CA125 was going up, round 5 up again. They are going to try two more rounds with a different chemo and if my CA125 hasn't gone done they said I'm probably platinum resistant. My doctor is talking about immunotherapy if I can't do the chemo anymore. Has anyone had this treatment and what kind of immunotherapy and is it working?
