Congratulations on completing your surgery and chemotherapy. To prevent recurrence, maintenance therapy is now the standard of care for stage 3C ovarian cancer. The main options include: 1. PARP Inhibitors (such as Olaparib or Niraparib): These daily pills are highly effective, particularly if your tumor has a BRCA mutation or homologous recombination deficiency (HRD). 2. Bevacizumab (Avastin): A targeted IV therapy, often continued if you began taking it during chemotherapy. The best choice depends on genetic testing of your tumor. I highly recommend discussing genetic testing and these maintenance therapy options with your oncologist to customize your post-treatment plan.
