ABSTRACTObjective Patients living with myeloproliferative neoplasms (MPNs) suffer from symptom burden that affect quality of life. Due to the differences in cultures, climates, and genetic background, we aimed to investigate the symptom burden of Thai MPN patients Methods A comprehensive survey using the MPN-10 questionnaire was carried out between September 1, 2014, and September 30, 2017. The scores obtained were then correlated with clinical outcomes.. Results A total of 145 patients were enrolled. Nearly 90% of patients reported being symptomatic. The mean MPN-10 score was 13.6 (SD = 11). The mean MPN-10 score was highest in PMF, whereas the mean score and intensity of individual items were surprisingly low in ET and PV. Notably, the mean MPN-10 score was significantly higher in patients with documented splenomegaly compared to those with a normal-sized spleen. However, there were no correlations between MPN-10 scores and the mutation status, disease complications such as thrombosis and hemorrhage, progression to myelofibrosis or leukemia, and mortality. Patients who needed regular transfusions reported a higher MPN-10 score compared to those who did not. Conclusion The MPN-10 score did not predict survival outcomes among Thai MPN patients. Higher MPN-10 was associated with more transfusion. Thai MPN patients reported lower MPN-10 compared to western population especially PV and ET.
