Early diagnosis is key with ovarian cancer, so it sound like your mother was lucky to have had it caught in time.

You might consider asking her oncologist if they intend to use PARP inhibitors post chemo to help keep the cancer in remission. There are currently several promising clinical trials ongoing for immunotherapy protocols for ovarian cancer, so the goal would be to keep the cancer in remission until those are generally available.

Wishing the best, take care.

(Not a medical practitioner, bring questions and information to your mother’s doctors, and do not feel intimidated to ask questions based on your research)
