Therapy related acute myeloid leukemia and myelodysplasia (t-MN) is a potential late complication of cytotoxic therapy, and it is of particular concern in the treatment of patients with epithelial ovarian carcinoma (EOC) exposed to multiple cycles of platinum-based chemotherapy during the course of their disease. An epidemiological analysis published in 2011 (Gynecologic Oncology) showed that the overall incidence of t-AML is 0.17%, with a median latency to development of leukemia of 4 years (range 0-27 years). Inhibition of PARP is a potential synthetic lethal therapeutic strategy for the treatment of cancers characterized by specific DNA repair defects, such as those that harbor a BRCA1 or BRCA2 (BRCA1/2) mutation and are therefore deficient in homologous recombination repair. In homologous recombination-deficient tumors, PARP inhibition eliminates an alternative DNA repair pathway essential for maintaining viability, leading to tumor cell death. The estimated prevalence of BRCA1/2 mutations in V2 03/06/2021 2 patients with newly diagnosed high-grade serous ovarian cancer is 20-25% and it might be higher in patients with platinum-sensitive, relapsed ovarian cancer. Early studies have shown significant efficacy for PARP inhibitors in patients with germline BRCA1/2 mutations. Our hypothesis is that these patients are carriers of clonal hematopoiesis of indeterminate potential (CHIP) before treatment with PARPi. CHIP refers to the presence of clonal population(s) of hematopo…
