Presentation of the myeloproliferative neoplasms (MPNs) varies widely, and correct diagnosis and management can be challenging, and is becoming more complex as understanding of the underlying molecular basis for these disorders emerges. Appropriate management is increasingly informed by accurate risk stratification founded on understanding of cytogenetic and molecular markers, as well as the clinical presentation. ‘Fast Facts: myeloproliferative neoplasms’ focuses on the three most common chronic MPNs: • Essential thrombocythemia (ET) – characterized by increased platelet count • Polycythemia vera (PV) – characterized by excessive production of red blood cells • Primary myelofibrosis – a more severe and heterogenous disorder that may overlap with ET and PV but is commonly associated with anemia. Written by two leading experts in the field, Fast Facts: myeloproliferative neoplasms provides concise, up-to-date and practical guidance on the accurate diagnosis, risk stratification and management of these MPNs. It also provides key insights into our growing understanding of the underlying molecular and genetic basis of these disorders, and how this is informing risk stratification and management strategies. This concise handbook will be invaluable to clinicians, medical students, nurses, pharmacists and scientists in understanding and overcoming the everyday and rarer challenges associated with MPN.
