Classic BCR::ABL1-negative myeloproliferative neoplasms (MPN) include polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF). While patients may benefit from extended survival, they also endure lifelong symptoms, ranging from mild to incapacitating [1]. These include physical manifestations related to hyperviscosity, bone pain, pruritus, constitutional symptoms, and consequences of splenomegaly, among others, as well as psychological symptoms (e.g., depression, anxiety) [2, 3]. Ultimately, symptom burden impairs quality of life (QoL) [4], an independent predictor of mortality [5]. Addressing symptom burden in MPN patients is crucial in guiding and individualizing therapy; however, several important challenges remain, including obscure mechanistic underpinnings and scarcity of robust data to inform practice. While the current patient-reported symptom assessment tool was conceived as a universal instrument for the collective MPN population—facilitating its clinical application, distinct profiles across subtypes may not be captured. Cut-off values determining ‘significant’ scores may also warrant further evaluation. Furthermore, kinetics of symptom profiles over time and correlations with biological variables have not fully been explored. The objectives of the current study were to comprehensively characterize symptom burden in a large MPN cohort, determining: i) age/sex-associated differences; ii) longitudinal dynamics and treatment effects; iii) biologic correlatives; and iv) impact on overall survival (OS) in a real-world population-based setting.

Abstract

Myeloproliferative neoplasms (MPN) are associated with a variety of symptoms that severely impact patients’ quality of life and ability to perform daily activities. Recent studies showed differences in the perception of physician- versus patient-reported symptom burden. However, studies directly comparing patient- and physician-reported ratings are lacking. Here, a retrospective analysis on symptom burden of 3979 MPN patients of the Bioregistry of the German Study Group for MPN was conducted to intra-individually compare physician and patient reports collected at the same time. Cohen’s kappa was calculated to assess the degree of agreement between patient and physician reports. Factors influencing baseline symptom severity were identified using linear regression and adjusted Cox models were calculated to investigate the effect of symptom burden on survival. MPN patients had a high symptom burden, which neither decreased over time nor upon cytoreductive therapy. All symptoms were more frequently reported by patients compared to physicians. Agreement remained low and only slightly improved when considering a higher threshold for patient symptom severity. Patients with severe symptom burden had inferior survival compared to patients with less severe symptoms. Assessment of symptom burden in MPN is therefore insufficient and patient-reported outcome tools need to be implemented into clinical routine.

Author(s): Mary Caffrey

When patients with myeloproliferative neoplasms (MPNs) must travel 2 hours for appointments with a cancer care team, capturing all their symptoms to ensure proper treatment is vital.

So, when Charleston Area Medical Center (AMC) Vandalia Health, located in Charleston, West Virginia, signed on to be part of the Association of Cancer Care Centers (ACCC) MPN Quality Improvement Program, systematic and accurate recording of patients’ symptoms was a priority. In a 12-month period, the cancer program serves 78 patients with polycythemia vera, 111 patients with essential thrombocythemia, and 48 patients with primary myelofibrosis.

Charleston AMC serves a large area in southern West Virginia, including some heavily rural areas. Its team includes general medical oncologists and hematologists who treat all types of cancers, 5 patient navigators, and 2 financial navigators who deal with insurance coverage, transportation issues, and other barriers to access. There is 1 social worker as well as nurses and other team members. Complementing the team are outside partners who help Charleston AMC meet multiple social needs.

As with ACCC Quality Improvement Program participants from Perlmutter Cancer Center at NYU Langone Health and Kent Hospital in Rhode Island, the multidisciplinary team in Charleston West Virginia, first took part in a webinar on MPN patient management.1

The ACCC Quality Improvement program was supported by Incyte.

The Charleston AMC team learned about the MPN Symptom Assessment Form Total Symptom Score (MPN-SAF TSS),2 a validated MPN patient-reported outcome tool that is recommended in the National Comprehensive Cancer Network Guidelines. Patients complete the assessment when they arrive at their appointments, giving providers an overview of symptoms that can be tracked over time.

Fedratinib Alleviates Symptoms, Reduces Spleen Volume in MDS, MPNs

Fedratinib can reduce symptoms and spleen volume in patients with myelodysplastic syndrome (MDS) or myeloproliferative neoplasms (MPNs), according to research presented at the ASH Annual Meeting 2024.

Researchers are evaluating fedratinib, a JAK2 inhibitor, in a phase 2 trial. The trial (NCT05177211) enrolled 25 patients with atypical chronic myeloid leukemia (n=6), chronic neutrophilic leukemia (n=5), MDS/MPN-unclassifiable (n=8), and MDS/MPN with ring sideroblasts and thrombocytosis (n=6).

At baseline, the median patient age was 68.8 (range, 39.9-84.7) years, and the median time from diagnosis to treatment was 7.1 months. Most patients had splenomegaly (83%), and the median MPN-Symptom Assessment Form Total Symptom Score was 21 (range, 1-73). Prior treatments included hydroxyurea (36%), ruxolitinib (20%), luspatercept (8%), and hypomethylating agents (12%). Patients had a median of 3 pathogenic mutations.

“Most of these patients had multiple mutations, and most had a signaling mutation, an epigenetic mutation, and a splicing mutation,” said study presenter Andrew Kuykendall, MD, of the Moffitt Cancer Center in Tampa, Florida.

The patients received fedratinib at a dose of 400 mg daily in 28-day cycles. They could continue on treatment as long as they had a clinical benefit. At last follow-up, 11 patients were still on study treatment.

The median duration of fedratinib treatment was 10.8 months, and 21 patients were evaluable for efficacy at 24 weeks. Three patients discontinued fedratinib prior to 24 weeks for reasons unrelated to toxicity or lack of efficacy (eg, cost) and were considered non-responders.

Learning more about the different symptoms and treatment goals of myeloproliferative neoplasms (MPNs) can help patients be more involved in management decisions throughout the disease trajectory, an expert said.

“It’s not just the doctor and the nurses; it’s the person who has the disease [that] is the main person, so their involvement is very important,” said Dr. Swati Goel at the recent CURE® Educated Patient® Updates in MPNs at Montefiore Medical Center in the Bronx, New York.

Goel is the Leader of the Myeloproliferative Disorder Clinic, assistant director of the hematology-oncology fellowship program and associate professor in the department of oncology and medicine at Montefiore Einstein in New York, New York.

Throughout the event, Goel discussed that there are three types of MPNs: polycythemia vera (PV), essential thrombocythemia (ET) and myelofibrosis.

Abstract

Background: Although high symptom burden indicates poor survival and informs treatment decisions, little is known about the impact of demographic, clinical, and laboratory features on total symptom score (TSS) in patients with myeloproliferative neoplasms (MPN).
Methods: Patients with MPN (polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF)) were identified from the retrospective chart review. TSS, individual symptom scores (fatigue, early satiety, abdominal discomfort, inactivity, concentration problems, fever, night sweats, itching, bone pain, weight loss), demographic characteristics (race, ethnicity, age, gender), clinical features (time since diagnosis, depression status, obesity status, spleen size), laboratory results and season at the time of visit were recorded from the clinical encounter when index assessment of TSS was performed for each patient. Normality was assessed using visual inspection of data distribution, whereas multicollinearity was assessed using various inflation factors. A univariable regression followed by a multivariable regression analysis was conducted using a backward selection approach. A p-value <0.05 indicated a statistically significant association of a given feature with TSS.
Results: The chart review identified 252 patients (PV: 78; ET: 81; MF: 93). Mean age was 59 (SD: 17.7), 67 (SD: 13.0), and 68 (SD: 10.9) years for ET, PV, and MF respectively. Most patients were white (PV, MF: 92%; ET: 83%) and females (ET: 75%; PV: 60%; MF: 53%). The TSS of patients was highest with PV (mean: 18.5; SD: 16.9) followed by MF (mean: 18.1; SD: 15.4) and ET (mean: 14.3; SD: 15.9). Fatigue was the most reported symptom whereas the least reported symptoms were fever and weight loss. Univariable regression analyses showed depression (B: 17.7; p=0.02), female gender (B: 10.6; p=0.01), platelet count (B: 0.03; p=0.03), and hemoglobin (Hb) (B: -2.6; p=0.01) in PV patients, depression (B: 19.8, p=2×10-5) in ET patients and depression (B: 11.0, p=0.03), white blood cell (WBC) count (B: 0.2; p=0.01), neutrophil count (B: 0.3, p=0.01), and non-neutrophil WBC count (B: 0.6; p=0.02) in MF patients to have significant association with TSS. Multivariable regression analyses (Table) showed Hb (B: -2.5; p=0.01) and platelet count (B: 0.02; p=0.03) in PV patients, depression (B: 19.7; p=2×10-5) in ET patients and depression (B: 12.3, p=0.01) and WBC count (B: 0.3; p=0.002) in MF patients to have a significant association with TSS.
Conclusions: Depression in ET and MF and low Hb in PV were identified as significant drivers of symptom burden. Identifying and managing patients with these comorbidities could improve their quality of life with a potential survival benefit.

MPN Symptoms Mimic Other Conditions, Open Communication Is Key

Posted on by

Brielle Benyon

Myeloproliferative neoplasm (MPN) symptoms can often appear as another condition, making it essential that patients find a cancer care team that they trust and can have open communication with, according to Patrick Buxton.

Buxton, who is a clinical nurse manager at Fred Hutchinson Cancer Center in Seattle and a 2023 MPN Hero, explained that certain side effects like constant fatigue could mimic conditions such as depression. That is why it is important for patients to work with their oncology team to establish a baseline of lab results and symptoms and keep them up to date on how they are feeling.
