I am so sorry to hear of your ovary .. we 3 seem to have very similar stories.
I also explored Hipec, but after much research, I did not do it. I may someday if I need however. I was told it was a very risky surgery to go through with no known cancer at that time. I instead did Folfiri, because Folfox was not an option after such a quick return of the cancer to my ovary. Again, basically did not work for me.
I had a bit of time pass before my third recurrence. I again explored Hipec, but again was advised not to do it as my recurrence was in the pelvis, and Hipec is not as effective on lower pelvic recurrence as it is on higher areas such as peritoneum. So, again, it is a tool I still have in my toolbox for future use. I instead had pelvic surgery removing all the cancer. It was very successful according to the surgeons.
So, you have some options. I would strongly suggest getting several different opinions and very importantly to do so at separate facilities. You have time during your recoup and will likely feel better after hearing from different professionals. I would also strongly suggest getting these opinions from experienced CRC surgeons. Feel free to PM me if you have any other questions.
I will say the hot flashes instantly were not fun.
I did not have much help with them. I was not on board with taking any other drug with the chemo I did after that surgery. So I learned to dress in layers, have a fan in my room at night, and used herbal ice packs around my neck. I also did acupuncture, which helped me a lot! They have subsided over time.
Wishing you a smooth recovery. Sending lots of well wishes your way!
