Background: Nedaplatin (NDP)-related hypersensitivity reactions (HSRs) trigger adverse clinical events. Prediction and prevention of NDP-HSRs are thus essential to minimize the risk and maximize the benefit of NDP therapy. However, the incidence of NDP-HSRs and the associated risk factors remain unclear. Methods: We retrospectively examined patients who received NDP monotherapy between April 2011 and July 2015 in Nagoya University Hospital. HSRs severity was defined according to the Common Terminology Criteria for Adverse Events version 4 (CTCAE ver.4). Risk factors for NDP-HSRs were determined using multivariate logistic regression. Results: Of 111 patients who received NDP monotherapy, 90 (81%) were female; median age was 59 years (range, 29–78 years). Eighty-eight patients had gynecological cancer and 20 suffered from head and neck cancer. Eight of 111 patients (7.2%) experienced NDP-HSRs, six of which developed in the second NDP cycle. However, all patients with NDP-HSRs were treated with carboplatin (CBDCA) for more than three cycles. Grade 3 and 4 HSRs developed in 2 patients. NDP-HSRs were significantly associated with a history of CBDCA-HSRs (odds ratio 37.5, 95% confidence interval 5.38–262, p < 0.001) and with the interval between NDP administration and the previous platinum treatment (odds ratio 13.9, 95% confidence interval 1.23–158, p = 0.034). Conclusion: The risk of NDP-HSRs increases in patients with a history of CBDCA-HSRs and in those administered NDP for more than 6 months after previous platinum treatment. Such individuals must be closely monitored if given NDP, even if they are expected to benefit from the treatment.
