Variables associated with patient-reported outcomes in patients with myeloproliferative neoplasms

Abstract

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.
