Abstract
The success of ovarian cancer treatment is hampered by the recurrent nature and the resistance or hypersensitivity to a platinum regimen. The addition of poly (ADP-ribose) polymerase (PARP) inhibitors can increase the sensitivity to platinum-resistant tumors, although while increasing risk of hematologic toxicity. Substituting cisplatin for carboplatin could result in satisfactory outcomes in the case of carboplatin hypersensitivity. However, there are no efficacy and safety data regarding continuous low-dose cisplatin infusion combined with an oral PARP inhibitor for ovarian cancer patients with hypersensitivity to carboplatin. Herein, we report the case of a heavily pretreated ovarian cancer patient with carboplatin hypersensitivity who safely received low-dose cisplatin (30 mg/m2 every 3 weeks) over a 48-h infusion combined with a PARP inhibitor for a total of 10 days (D− 2–D7) and successfully achieved partial response after four cycles of treatment, the efficacy of which was further enhanced by the addition of deep regional hyperthermia.
