Epithelial Ovarian cancer (EOC) is the most lethal gynecologic cancer worldwide. Carboplatin (CP) is the main chemotherapeutic agent in the treatment of ovarian cancer. However, the development of a hypersensitivity reaction (HSR) in 10% to 15% of patients with EOC is an important limiting factor for the clinical use of CP. Herein, we aimed to investigate the efficacy and safety of CP-desensitization (CP-D) therapy in the treatment of recurrent patients with EOC. Forty-seven ovarian cancer cases treated with CP-desensitization at the Istanbul University Oncology Institute were retrospectively analyzed between 01.01.2017 and 01.01.2022. The decision for CP-D was based on the patients' history of HSR and/or a positive skin test. For all patients, a 6-hour 12-step rapid drug desensitization protocol with a 30-minutes premedication regimen was used. Forty-seven patients were included in this study, and the median age at diagnosis was 53 years (range; 27-80). Twenty-one (43.7%) patients had 1 or more comorbid diseases, and 12.7% had a previous history of drug allergy. On average, HSR due to carboplatin was identified after 9 (7-16) cycles, and carboplatin was administered n = 11 (range, 3-36) times to patients. The overall survival from the first desensitization procedure (0S2) was 42.2 months (range: 25.3-59.1), and the 1-, 2-, and 5-years survival rates were 92.6%, 75.6%, and 47.2%, respectively. The objective response rate (ORR) was 78.5%. Cumulatively, 496 CP-D procedures were performed, of which 478 (96.3%) were successfully completed. None of the patients included in this study developed severe (grade 3-4) HSR during CP administration (no adrenaline was used, no need for intensive care). No deaths due to CP-D were noted. CP-D is a beneficial and safe method in treating platinum-sensitive recurrent EOC patients with CP-induced HSR.
