Background: Hypersensitivity reactions (HSRs) to platinum are an important issue in the treatment of patients (pts) with ovarian cancer (OC). Germline BRCA mutations have been proposed as a risk factor. We aimed at evaluating the incidence and severity of HSRs to platinum in OC pts. with known BRCA status. Patients and methods: We retrospectively analyzed 432 pts. from 5 Italian Centers. In addition, we performed a systematic review and meta-analysis of published series. Results: Four hundred nine pts. received at least one prior platinum-based treatment line: 314 were BRCA wild type (77%) and 95 were BRCA mutated (23%). There was no statistical difference in exposure to platinum. Incidence of any grade HSRs was higher among BRCA mutated pts. [9% vs 18%, p = 0.019] and the time-to-HSRs curves show that the risk increases with the duration of platinum exposure, in BRCA mutated pts. more than in BRCA wild type. A multivariable analysis showed that harboring a germline BRCA mutation was related to a higher incidence of HSRs (HR: 1.84, 95% CI 1.00–3.99, p = 0.05) while having received pegylated liposomal doxorubicin (PLD) was related to a lower incidence of HSRs (HR: 0.03 95% CI 0.004–0.22, p = 0.001). The systematic review confirmed the higher incidence of HSRs in BRCA mutated pts., though heterogeneity among series was significant. Conclusions: In OC pts. with BRCA mutations, there is a significantly higher incidence of HSRs to carboplatin, not justified by longer drug exposure. On the other hand, PLD exerted a protective role in our series.

Abstract
Background: Hypersensitivity reactions (HSRs) to platinum are an important issue in the treatment of patients (pts) with ovarian cancer (OC). Germline BRCA mutations have been proposed as a risk factor. We aimed at evaluating the incidence and severity of HSRs to platinum in OC pts. with known BRCA status. Patients and methods: We retrospectively analyzed 432 pts. from 5 Italian Centers. In addition, we performed a systematic review and meta-analysis of published series. Results: Four hundred nine pts. received at least one prior platinum-based treatment line: 314 were BRCA wild type (77%) and 95 were BRCA mutated (23%). There was no statistical difference in exposure to platinum. Incidence of any grade HSRs was higher among BRCA mutated pts. [9% vs 18%, p = 0.019] and the time-to-HSRs curves show that the risk increases with the duration of platinum exposure, in BRCA mutated pts. more than in BRCA wild type. A multivariable analysis showed that harboring a germline BRCA mutation was related to a higher incidence of HSRs (HR: 1.84, 95% CI 1.00–3.99, p = 0.05) while having received pegylated liposomal doxorubicin (PLD) was related to a lower incidence of HSRs (HR: 0.03 95% CI 0.004–0.22, p = 0.001).
