Hello. I'm sorry to hear that you are experiencing a recurrence. My mother was diagnosed IIIC and used monthly doxil/carboplatin as a second-line treatment. Her CA-125 began to fall after three treatments. She never went into complete remission, though her disease was kept stable for 8-9 months, and she enjoyed a relatively high quality of life for all but a few days each month. As for response rates to doxil (partial and complete), I have seen trials resulting in statistics between 25-35%.
Best wishes. I have my fingers crossed for you.
