Abstract

Heavily pretreated ovarian cancer patients become progressively chemoresistant, and thereafter, only scant treatments potentially accord reasonable, albeit limited clinical efficacy. We describe a case involving a 67-year-old ovarian cancer patient who underwent multiple lines of chemotherapy and presented with recurrent disease and a CA-125 of 4112 U/mL. Thenceforth, she was treated with GL-ONC1 oncolytic viral therapy that was administered laparoscopically in accordance with a clinical trial. The patient subsequently received chemotherapy and during the fourth cycle, her CA-125 decreased to 99 U/mL; moreover, a computed tomography scan of the pelvis exhibited significant disease reduction. Viral therapy hypothetically confers significant promise in the treatment of recurrent ovarian cancer, especially in patients who remain unresponsive to traditional medications.
