Most of OC have spread to peritoneum by the time of diagnosis Intraperitoneal (IP) chemotherapy prolonged survival time and reduced the risk of death. Higher rate of adverse events and the frequency of discontinuation hampered adoption Abdominal pain, Nausea, Vomiting, Fatigue, Infection, IleusHyperthermia enhanced cancer cell destruction HIPEC-based regimens might PFS and OS for patients with advanced primary ovarian cancer.

When mutated that mechanism is damaged

For those who have completed two or more lines of platinum-based therapy, consider niraparib maintenance therapy if partial or complete response
For those with BRCA1/2 mutations who have completed
one or more lines of platinum-based therapy, consider olaparib maintenance therapy if partial or complete response
For platinum-sensitive recurrent disease, if response after chemotherapy, bevacizumab can be continued as maintenance therapy until disease progression or unacceptable toxicity
