Ovarian Carcinosarcoma and Response to Immunotherapy

Ovarian carcinosarcoma (OCS) is an uncommon and highly aggressive subtype of ovarian cancer. This form of cancer is characterized by limited treatment options and a poor prognosis. In this report, we present a case study of a 64-year-old female diagnosed with stage III OCS, who underwent debulking surgery and adjuvant chemotherapy, followed by immunotherapy, with encouraging outcomes. Despite the availability of diverse chemotherapy options, the prognosis for patients with OCS remains grim. However, the present case study of a 64-year-old female with OCS illustrates the promising outcomes achieved with immunotherapy. Additionally, this case highlights the significance of microsatellite instability testing in guiding treatment decisions for ovarian cancers of this nature.
