title: Clinical features of hypersensitivity reactions to carboplatin.
abstract: OBJECTIVE
  To characterize the clinical features of carboplatin-associated hypersensitivity reactions.
  
  
  METHODS
  Patients with gynecologic malignancies treated at the Cleveland Clinic Foundation from June 1995 through July 1998 who experienced a carboplatin-associated hypersensitivity reaction were the subjects of this evaluation.
  
  
  RESULTS
  Of the 205 patients treated with carboplatin during this time period, 24 (12%) developed a carboplatin hypersensitivity reaction. The median number of platinum (carboplatin plus cisplatin) courses for the first episode was eight (range, six to 21). Only three patients (13%) developed this toxicity during their initial chemotherapy regimen, with the remainder experiencing a reaction during their second (n = 15) or third (n = 6) carboplatin treatment program for recurrent disease. Thirteen patients (54%) developed at least moderately severe symptoms (diffuse erythroderma, tachycardia, chest tightness, wheezing, facial swelling, dyspnea, hypertension, or hypotension). In approximately one half of patients, the reaction developed after more than 50% of the carboplatin had been infused. Only one of three patients was successfully treated with the agent upon rechallenge.
  
  
  CONCLUSIONS
  Carboplatin hypersensitivity reactions develop in patients who have been extensively pretreated with the agent. The clinical features are highly variable, but they are sufficiently different from those noted after the administration of paclitaxel that it should not be difficult to distinguish between reactions to the two agents. As carboplatin is increasingly used as initial and second-line chemotherapy of ovarian cancer and other malignancies, it can be anticipated that hypersensitivity reactions to the drug will become a more common and difficult clinical management issue.
