e21684 Background: Pharmacologic therapy stabilizes hematologic counts and splenomegaly in myeloproliferative neoplasms (MPN), however only partial symptom improvement typically occurs. Evidenced-based supportive care interventions are needed, however data is limited in patients with MPNs. Methods: Patients were recruited internationally via social media. Informed consent and online self-report surveys (Qualtrics) were completed capturing patient demographics, disease specific data, supportive care utilization, and symptom burden via MPN-SAF TSS. ANOVA, chi square tests, and Wilcoxon rank sum tests methods were applied. Results: Patients:1087 patient surveys were consented. Of these, 858 had 10 or more responses. There were 338 essential thrombocytosis (ET), 188 myelofibrosis (MF), 315 polycythemia vera (PV), and 17 other. In MF: DIPSS risk categories included low (8%), Int-1 (19%), Int-2 (29%), high (12%), and unknown (32%). Supportive care:The most frequently utilized therapies were aerobic activity in 442 patients (51.5%), massage in 244 (28.4%), yoga in 220(25.6%), nutrition in 216 (25.1%), and strength training in 204 (23.7%). Symptom association: Among all respondents, aerobic activity (p=<0.001), massage (p=<0.001), yoga (p=0.02), and strength training (p=<0.001) was associated with lower symptom burden by the MPN-SAF TSS however, nutrition was not (p=0.10). In ET and PV subgroups, yoga intervention was no longer statistically significant (p=0.35, p=0.14). In the MF subgroup, no intervention was found to be significant in any risk category. Conclusions: Supportive care with aerobic activity, massage, yoga, and strength training is associated with improved symptom burden in patients with MPN. Further studies are needed to understand the benefits of such therapies. [Table: see text]

Purpose: Essential thrombocythemia, polycythemia vera, and myelofibrosis are rare chronic hematological malignancies known as myeloproliferative neoplasms (MPNs) and are characterized by deregulated myeloid lineage cell production, splenomegaly, and heterogeneous symptom profiles. MPN patients suffer from a significant symptom burden (eg, fatigue, depressive symptoms, early satiety) and an impaired overall quality of life (QoL). Current treatments typically include pharmacological approaches, which may come with additional side effects and may be limited by treatment-associated toxicities (ie, cytopenias). Nonpharmacological approaches such as physical activity may be beneficial for reducing symptom burden and improving QoL. To date, no studies have examined physical activity as a nonpharmacological approach in MPN patients despite preliminary evidence supporting its benefit in other hematological cancers. The purpose of this article is to (1) review the literature related to physical activity and specific hematological cancer subtypes and to (2) make suggestions for future research involving physical activity in MPN patients as a symptom management strategy. Methods: A brief review of studies examining physical activity in leukemias, lymphomas, and myelomas (excluding stem-cell transplant patients) was conducted. Results: There is preliminary evidence to suggest that physical activity may be an effective approach to improve patient-reported outcomes (fatigue, depression, anxiety, sleep), physical fitness (cardiovascular fitness, balance, body composition), and overall QoL in other hematological cancers. Conclusions: Based on encouraging findings in other hematological cancers, future research should examine the feasibility and effectiveness of physical activity in MPN patients.
