Hypersensitivity Reaction to Carboplatin in Gynecologic Cancer: A Case Report and a Review of the Literature

Abstract

A combination chemotherapy of paclitaxel plus carboplatin (TC) is the most frequently used regimen for gynecological malignancies. As long as it is effective, a carboplatin-containing combination chemotherapy is used for every relapse. This implies that the number of platinum administrations and the frequency of hypersensitivity reaction (HSR) increase as the prognosis improves. When a patient develops HSR to carboplatin, we have three options: 1) desensitizing and continuing to use carboplatin, 2) switching to other platinum drugs, or 3) changing to a non-platinum drug. Here we report an experience of an HSR to carboplatin in a patient with recurrent uterine carcinosarcoma. The patient was treated by surgery and TC therapy initially, resulting in no residual disease. The patient relapsed 18 months after the completion of the first-line chemotherapy and was treated with TC therapy again as second-line. An HSR to carboplatin occurred at the 10th cycle of TC in total. We replaced the carboplatin with cisplatin. A chemotherapy including cisplatin and adriamycin was repeated without further HSR. We reviewed the literature regarding HSR to carboplatin and in this paper we summarize the management for dealing with it.
