Hi Deb, I also have primary peritoneal cancer. Diagnosed in march 2002. I was also told that it is treated the same as ovarian cancer. I did have some right ovary involvment. Had complete histo,2 bowel resections,& debulking of the omentum. Then went on to have 6 treatments of carbo/taxol. My CA125 counts went from over 4000 down to 11. Have been in remission now since. I ask my oncologist about taking vitamins during treatment and he said it won't hurt, who knows it may help. So I have been taking Shakley vitamins plus C & E. Don't know if it has helped,but it hasn't hurt! I go every 3 months for checkups and have a CA125 done, so far so good, my last count was 20 so I am in the normal range. All I can say is try to keep a positive outlook on things. I know that is d--- hard to do sometimes. I have battles with that myself, I do find that reading the stories in this discussion help a lot,I do not know anyone who has the same cancer that I could speak to personally so this is the next best thing. Actually probably better because there are so many of us,with such varied ideas. Thanks to all of you that write in this group. you are a big help. Minnie
