Myeloproliferative neoplasms and pregnancy

Introduction. The Myeloproliferative Neoplasms are a heterogeneous group of clonal hematopoietic stem cell disorders characterized by increased proliferation of the myeloid lineages in the bone marrow. A particular clinical challenge is presented by certain situations in patients with myeloproliferative Neoplasms, which we do not encounter daily. For this reason, in this paper, we will emphasize the approach to overcoming obstacles in patients with Myeloproliferative Neoplasms in specific settings, like pregnancy. Pregnancy with Philadelphia chromosome-negative Myeloproliferative Neoplasms has been reported to be associated with maternal thrombosis, hemorrhage, and placental dysfunction leading to fetal growth restriction or loss. Thrombocytosis, leucocytosis, high level of hematocrit, activation of Platelets, leucocytes, and circulating pro-thrombotic are connected with the pathogenesis of thrombosis in MPNs With survival expectations similar to age-matched controls and excellent response and worldwide access to tyrosine kinase inhibitors, family planning is increasingly important for many patients with chronic myeloid leukemia. All patients were managed by a multidisciplinary team of physicians with obligatory hematological and gynecologistsobstetrician consultations.
