ABSTRACT

The management of pregnant patients with essential thrombocythemia (ET) and polycythemia vera (PV) may be problematic. In the literature there are ~300 cases of pregnancies reported in ET and less than 50 pregnancies reported in PV. To reduce the effect of reporting bias, we selected articles with either > 10 pregnancies or at least six patients, and here report on the outcome of 195 pregnancies in ET and 36 pregnancies in PV patients. The live birth rate was ~60% in ET and 58% in PV. Spontaneous abortion during the first trimester was the most frequent fetal complication, occurring in 31% of ET pregnancies and in 22% of PV pregnancies, respectively. Major maternal complications were more frequent in PV compared with ET (44.4 versus 7.7%). Treatment with low-dose aspirin during pregnancy in ET seemed to reduce complications and also seemed beneficial during pregnancy in PV. In high-risk pregnancies, the additional use of low molecular weight heparin and/or interferon α should be considered. This article also describes a registry for an observational study concerning pregnancy in chronic Philadelphia chromosome-negative myeloproliferative disorders within the European LeukemiaNet. A potential management algorithm for pregnancies in ET or PV is also provided.
