Ovarian cancer (OC) is a leading cause of gynecologic cancer-related deaths. Despite improvements, the 10-year survival rate has remained relatively unchanged in recent years. Disease recurrence occurs in nearly 80% of patients with advanced disease symptoms. Hyperthermic intraperitoneal chemotherapy (HIPEC) is a therapy that targets common sites of OC recurrence with heated chemotherapy during surgery, which promotes either direct cell death, heightened deoxyribonucleic acid damage, or increased tumor susceptibility to chemotherapeutics. Clinical trials utilizing HIPEC have shown promising results. This paper aims to provide an overview of HIPEC, including historical trials, mechanistic insights, recent advances, and ongoing clinical trials.
