Abstract:
OBJECTIVETo investigate the complications and conversions in myeloproliferative disorders (MPD).
METHODSThree hundred and fifty six patients with MPD were reviewed, including 78 with etiologic thrombocythemia (ET), 93 with primary myelofibrosis (MF), 185 with polythythemia vera (PV). The clinical observation, follow-up, analysis with SPSS statistic software were performed.
RESULTSOut of the 356 cases, 101 (28.5%) developed thromboembolic events, 81 (22.8%) hemorrhage, 60 (16.9%) hypertension, 20 (5.6%) coronary heart disease, 3 (0.8%) hemolysis and 1 (0.3%) gastrointestinal ulcer, 2 (0.6%) calculus and 1 (0.3%) bone marrow necrosis. Twenty four patients (6.7%) developed MF (9 in ET, 15 in PV), 2 (0.6%) erythrocytosis (1 in ET, 1 in MF), 3 (0.8%) thrombocythemia (all in PV), 5 (1.4%) acute leukemia (2 in ET, 3 in MF) and 1 (0.3%) multiple myeloma (in ET). Eleven cases (3.1%) died, 5 (1.4%) from acute leukemia, 2 (0.6%) fatal hemorrhages, 1 (0.3%) each myocardial infarction and infectious shock, 2 (0.6%) unknown causes.
CONCLUSIONEmbolism and bleeding were the main complications in MPD. Conversions among ET, MF and PV hematological malignancies could occur.
