OBJECTIVE: Repeated exposure to carboplatin can lead to hypersensitivity reactions during retreatment with carboplatin. This may prevent its further use in platinum-sensitive ovarian cancer patients. At our institution, an increasing proportion of patients are prophylactically converted to an extended schedule of infusion after 8 cycles of carboplatin. We sought to determine whether an incrementally increasing, extended 3-hour infusion of carboplatin with appropriate premedication was associated with a lower rate of hypersensitivity reactions compared to the standard 30-minute schedule in sequentially treated patients.
METHODS: We performed a retrospective electronic medical record review of patients with recurrent ovarian cancer retreated with carboplatin at our institution from January 1998 to December 2008.
RESULTS: Seven hundred and seventy-seven patients with relapsed ovarian, fallopian tube, or primary peritoneal cancer were retreated with carboplatin and met study inclusion criteria. Of these, 117 (17%) developed hypersensitivity reactions during second-line or greater carboplatin-based treatment for recurrent disease. Only 6 (3.4%) of the 174 patients who received the extended schedule developed hypersensitivity reactions (0% grade 4; 50% grade 3) compared to 111 (21%) of 533 patients in the standard schedule group (13% grade 4; 77% grade 3). The first hypersensitivity episode occurred after a median of 16 platinum (carboplatin and cisplatin) treatments in the extended group compared to 9 in the standard group. Using the Fisher exact test, there was an association with a reduced incidence of hypersensitivity reactions with the extended infusion schedule (P<0.001).
CONCLUSION: Our data suggest appropriate premedication and prophylactic conversion to an extended infusion during carboplatin retreatment may reduce hypersensitivity reactions.
