RESUMO
INTRODUCTION: Genetic landscape, disease characteristics, and clinical outcomes of young adults with myeloproliferative neoplasms (MPNs) were reported. However, data on patient-reported outcomes (PROs) in young adults with MPNs were rare. METHODS: We conducted a multicenter, cross-sectional study to compare the PROs in respondents with thrombocythemia (ET), polycythemia vera (PV), and myelofibrosis (MF) by age at survey, including the young group (18-40 years), middle-aged group (41-60 years), and elderly group (>60 years). RESULTS: Of the 1,664 respondents with MPNs, 349 (21.0%) were young including 244 (69.9%) with ET, 34 (9.7%) with PV, and 71 (20.3%) with MF. In multivariate analyses, the young groups with ET and MF were associated with the lowest MPN-10 scores among the 3 age groups; those with MF, highest proportion of reporting negative impact of disease and therapy on their daily life and work. The young groups with MPNs had the highest physical component summary scores but the lowest mental component summary scores in those with ET. The young groups with MPNs were most concerned about fertility; those with ET, treatment-related adverse events and long-term efficacy of treatment. CONCLUSIONS: We concluded that young adults with MPNs have different PROs compared with middle-aged and elderly patients.

Background: Patients with myeloproliferative neoplasms (MPNs) experience a high disease-related symptom burden. A specific instrument to evaluate quality of life (QoL), i.e., the MPN Symptom Assessment Form Total Symptom Score (MPN-SAF TSS; MPN-10), was developed. We conducted the translation, cultural adaptation, and validation into Romanian of the MPN-10. Methods: We translated the MPN-10 and tested its psychometric properties. Results: We recruited 180 MPN patients: 66 polycythemia vera (36.67%), 61 essential thrombocythemia (33.89%), 51 primary and secondary myelofibrosis (SMF) (28.33%), and 2 MPN-unclassifiable (1.11%). The mean TSS was 19.51 ± 16.51 points. Fatigue, inactivity, and concentration problems were the most cumbersome symptoms. We detected scoring differences between MPN subtypes regarding weight loss (p < 0.001), fatigue (p = 0.006), early satiety (p = 0.007), night sweats (p = 0.047), pruritus (p = 0.05), and TSS (p = 0.021). There were strong positive associations between TSS and inactivity, fatigue, and concentration problems, and moderate negative correlations between QoL scores and all MPN-10 items. Cronbach's α internal consistency coefficient was 0.855. The Kaiser-Meyer-Olkin construct validity test result was 0.870 and the Bartlett Sphericity Test was significant (p < 0.001). Symptom scores were loaded into one single factor according to the exploratory factor analysis. Conclusions: The Romanian MPN-10 version displayed excellent psychometric properties and is a reliable instrument for assessing symptom burden and QoL in Romanian MPN patients.
RESUMO
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.

We explored variables associated with patient-reported outcomes (PROs) including symptom burden, impact on daily life and work, obstacles during therapy, satisfaction level with therapy, and health-related quality of life in 1500 respondents with myeloproliferative neoplasms (MPNs) including essential thrombocythemia (ET), polycythemia vera (PV) and myelofibrosis (MF) in a multicenter, cross-sectional study across China, a representative of the developing countries. In multivariate analyses, urban household registration and higher education level were significantly-associated with no symptoms at diagnosis in respondents with ET or MF. CALR mutation was significantly-associated with lower MPN-10 scores in respondents with MF. Higher MPN-10 scores were significantly-associated with negative impact on daily life and work as well as lower satisfaction level in respondents with ET, PV and MF. Receiving ruxolitinib was significantly-associated with high satisfaction and satisfaction in respondents with MF. In addition, other demographics and clinical variables were also impacting PROs.

BACKGROUND: Patients with myeloproliferative neoplasms (MPNs) suffer from chronic and progressive symptom burden. MPN trials capturing patient-reported symptoms routinely administer the MPN Symptom Assessment Form (SAF). The MPN-10 assesses 10 of the most clinically relevant symptoms, including fatigue and generates a Total Symptom Score (TSS). The original MPN-10 included a fatigue item from the Brief Fatigue Inventory (BFI). The myelofibrosis-specific symptom assessment tool called the MFSAF v4 utilizes a fatigue item developed to be consistent with other items within the SAF. This study sought to validate a modified version of the MPN-10 TSS using the SAF fatigue item for harmonization with MFSAF v4. METHODS: Survey data from two cohorts of patients with essential thrombocythemia, polycythemia vera, or myelofibrosis assessing MPN characteristics and symptom burden were used. RESULTS AND CONCLUSION: BFI and SAF fatigue items were highly correlated in raw score (Pearson r = 0.88), comparable in their severity categorizations (89% agreement for severe versus non-severe) and respective contributions to the TSS (both Cronbach's alpha = 0.89). Reliability of SAF fatigue was acceptable and independently associated with known disease-related characteristics (splenomegaly, low quality-of-life, and distress). Fatigue in patients with MPNs is measured with high similarity using the SAF fatigue item within the MPN-10 in harmonization with the MFSAF v4.
RESUMO
BACKGROUND: Identification of janus kinase 2 (JAK2) mutation even in absence of myeloproliferative disorders (MPNs) was found to be related to venous thromboembolism occurrence. Venous thrombosis screening is not routinely requested in patients with myeloproliferative neoplasms unless the patient is symptomatic. It has been reported that the incidence of thrombosis in elderly patients is much higher than in young patients. The aim of this work was to screen MPN patients for venous thrombosis and study its correlation with JAK2 allele burden and with MPN 10 score. PATIENTS AND METHODS: We enrolled 73 patients with JAK2-positive MPN from our Hematology Clinic in the period August 2015 to Feb 2017. All patients had been screened for thrombosis in the venous system in lower limbs (LLs), upper limbs, portal, and mesenteric systems using color Doppler ultrasound imaging. RESULTS: Fifty-three (72.6%) patients were younger than 60 years. Twenty-two (30%) had essential thrombocytosis, 35 (47.9%) had polycythemia rubra vera, and 16 (22%) had idiopathic myelofibrosis. Twenty-seven venous thrombotic attacks were reported in 22 (30.1%) patients. Five (6.8%) had thrombosis in 2 sites. Seventeen (23%) had superior mesenteric and portal vein thrombosis. Six (8%) had iliofemoral (8%) and 4 (5%) had combined LL and portal thrombosis. Eight (10.8%) had active thrombosis at screening. Only 3 patients (4%) were symptomatic with abdominal pain during screening. Pruritis (P = .02) and abdominal pain (P = .039) were significantly different between cases with and without thrombosis. There was no significant difference in MPN 10 score between cases with active or previous thrombosis. CONCLUSION: We recommend routine screening for venous thrombosis in any case of MPN when diagnosed and screening for MPNs in any patient with venous thrombosis especially of the portal vein or atypical sites. If MPN patients present with increasing pruritus or abdominal pain, they also should be screened for venous thrombosis. Further research on a large scale in MPN age groups younger than 60 years regarding pathogenesis of thrombosis is highly recommended.

JAK2, CALR, MPL and triple-negative mutational status has a direct impact on symptom severity and disease burden assessed by MPN10 score in myeloproliferative neoplasms (MPNs). Among 93 patients; median MPN10 score was 48 (5-76) in JAK2 mutants versus 25 (4-80) in JAK2 negative (p < .001); 22.5 (4-65) in CALR mutants versus 35 (5-80) in CALR negative (p < .050) and 21 (10-48) in triple negative versus 40 (4-80) in JAK2/CALR/MPL mutants (p < .001). At three years, progression free and overall survival of JAK2-positive versus JAK2-negative patients were 62% versus 100% (p < .001); 85% versus 100% (p = .011) and were 100% versus 78% (p = .067); 100% versus 92% (p = .197) in CALR-positive versus CALR-negative patients and 100% versus 75% (p = .004); 100% versus 90% (p = .015) in triple negative versus mutant patients, respectively. MPN10 score in association with driver gene mutations can be used as a predictor of survival in MPN patients.
