2016 ASH Annual Meeting
SAN DIEGO—Many patients living with myeloproliferative neoplasms (MPNs) have a high burden of disease that affects their quality of life and limits their ability to work, according to research presented at the 2016 ASH Annual Meeting.
Researchers conducted the first-ever international survey of MPN patients, including those with myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET).
Patients reported a high prevalence of symptoms, an increase in the number of symptoms from diagnosis, and reductions in emotional well-being, quality of life, and ability to work.
“The survey results help paint the full picture of the impact of these diseases,” said Claire Harrison, DM, of Guy’s and St. Thomas’ NHS Foundation Trust in London, UK.
“The dominating symptom is fatigue, which validates what we are seeing in the clinic. The novel findings regarding the impact on patient’s work life show the consequences of MPNs.”
Dr Harrison and her colleagues reported these findings at the meeting as (abstract 4267*).
The international MPN LANDMARK survey included 699 patients with MPNs (174 with MF, 223 with PV, and 302 with ET), and physicians who treated these conditions across Germany, Italy, UK, Japan, Canada, and Australia.
Patients completed an online questionnaire to measure MPN-related symptoms experienced over the past year and the impact of their condition on quality of life and ability to work.
Patients reported that their disease negatively impacted their ability to complete daily activities by 40%. Patients also noted 35% impairment in their capacity to work. Patients who missed work over the last 7 days due to illness reported missing an average of 3.1 hours due to their disease and/or symptom burden.
“For one quarter of PV patients, the disease stopped them from working, and another one quarter voluntarily reduced their work time,” Dr Harrison said. “This was surprising. Even though their disease was managed, it impacted their work life.”
She noted that many of her PV patients are young, working professionals.
Results also showed that about three-quarters of patients who experienced symptoms suffered a significant reduction in quality of life due to symptoms (83% of MF patients, 72% of PV patients, and 74% of ET patients).
These results are consistent with those from a previous US LANDMARK survey of MPN patients.
The most commonly reported symptom in the last 12 months was fatigue (54% of MF patients, 45% of PV patients, and 64% of ET patients). This was also the symptom patients stated they most wanted to resolve.
“Patients stated doctors often don’t ask enough about the details of symptoms,” Dr Harrison said.
In addition to physical symptoms, about one-third of patients felt anxious or worried about their disease (34% of MF patients, 29% of PV patients, and 26% of ET patients).
“We found a mismatch in aspirations of MPN patients and their physicians,” Dr Harrison said. “For example, physicians said it was important to teach PV patients to prevent blood clots. PV patients were more concerned with having a better quality of life and slowing disease progression.”
A comprehensive symptom assessment is important to help physicians understand other hardships of these diseases, she said, noting “in our service, we enlist nutritionists and psychologists and also use physiotherapists and occupational therapists.”
