Here, investigators use the World Health Organization's (WHO) database of individual safety case reports, to identify cases of pancytopenia related to PARPi.
Although PARP inhibitors (PARPi) have proved effective in treating many cancers, few patients receiving PARPi may experience rare but serious adverse events such as pancytopenia. Today, data about pancytopenia are scarce.~The objective was to investigate reports of pancytopenia adverse events related to PARPi, including olaparib, rucaparib, niraparib, talazoparib, veliparib and pamiparib using the World Health Organization's (WHO) pharmacovigilance database: VigiBase.
