Background: The COVID pandemic has resulted in significant changes many aspects of daily living. To understand the impact that COVID-19 has had on the myeloproliferative neoplasm (MPN) patient population, we conducted an internet based survey. Methods: Survey: This survey was hosted Mayo Clinic's secured REDCap system for online surveys with a link to the survey alongside a brief description posted via the www.mpnqol.com website, as well as other MPN organizational partners. Survey responses were completely anonymous. Questions included MPN-Total symptom score (TSS), NCCN distress thermometer (NCCN-DT), questions regarding impact on medical care, and questions from CDC COVID-19 community survey question bank regarding the impact of social distancing as well as changes in health behaviors. Distress thermometer, MPN-TSS, and/or questions related to the impact of COVID-19 on MPN treatment were analyzed by: MPN diagnosis, among those with ET, PV, or MF diagnoses; medication status; stay at home order; community spread; and country. Associations were tested using Kruskal-Wallis or Wilcoxon rank sum tests (for continuous variables) or Fisher Exact tests (for categorical variables). Analysis: Results: Patient Demographics (Table 1): 1560 people responded to the survey, 1217 were eligible for analysis. Median age was 62 (range: 21-93), and 298 (24.6%) respondents were male. There were respondents from USA, Australia, Canada, Netherlands, Ireland, and UK. 233 patients (19.2%) have myelofibrosis, 419 (34.6%) polycythemia vera and 543 (44.8%) essential thrombocythemia. At the time of the COVID outbreak, 1026 (84.3%) were on MPN directed medical therapy, including ruxolitinib (15.3%), interferon (14.7%), hydroxyurea (42.7%) and ASA (47.7%). 165 (13.6%) respondents received COVID testing, of which 5 had positive tests. Impact on MPN Care (Table 2): We sought to understand how patient's clinical care changed. Over half respondents who spoke to their MPN doctor had a telemedicine visit after COVID19 (57.1%). 422 (36.5%) patients spaced out visits, of which 99 (22.7%) felt there were consequences. A change in therapy due to COVID-1 occurred in only 5.4% of patients. MPN Symptom Burden and QoL: Data captured on the NCCN-DT had a median of 4 (0-10). MPN-SAF-TSS composite score was collected in 1150 respondents, median score was 26 (0-90). These scores are higher than those previously reported. Pandemic Impact on Lifestyle (Table 1): 595 (49.5%) of patients report living in a community where there is significant COVID-19 spread. 946 (78.9%) reported that COVID-19 has impacted their day to day life. 198 (17.2%) of patients agreed, or strongly agreed that COVID had a significant impact on their finances. 799 (67.8%) had a stay at home order. Of those who quarantined (112), the median duration was 30d (1-120). The majority of people increased hand-washing, and cleaning habits. 954 (81.7%) respondents reported wearing masks in public. 908 (76.8%) reported increased stress from social distancing. The majority of respondents report using healthy coping habits, such as reaching out to friends/loved ones, breathing and relaxation, as well as healthy diet. Less than 15% of patients report unhealthy coping strategies, such as use of opioids, benzodiazepines, alcohol, or cannabis Factors associated with response: There were no differences in responses based on type of MPN. If a patient was on medication, they were more likely to have spoken to their provider (p<0.001). If there was a stay at home order in place, there was a higher MPN-TSS score (p<0.001). If the respondent lived in an area of high community spread, they had a higher NCCN-DT score (p<0.001). Patients in the USA had a higher NCCN-DT score (p=0.001), were more likely to stretch out the duration of time between visits (p<0.001) and less likely to have a telemedicine visit (p<0.001). Although fewer respondents in the USA thought COVID-19 was a serious disease (p=0.02), a higher percentage of respondents wore masks (p <0.001). Conclusions: In our survey of MPN patients, there were many changes noted in clinical care. The use of telemedicine was common, and at least a third had significant changes in their care. Most experienced increased stress, however, employed healthy coping strategies. Only a minority of patients had a COVID test, and only 5 were positive, further data will be needed to understand the impact of COVID infection.

Abstract Introduction Multiple myeloma (MM) has characteristics that influence the prognosis and are useful to make decisions regarding treatment. Diagnosis and treatment patterns of hematological malignancies have not been described in Colombia and having access to this regional information could guide public health policies and help design clinical trials. The Colombian Association of Hematology and Oncology (ACHO) designed a registry for Hemato-Oncological diseases to fill this information gap. This is the first report of RENEHOC focusing on MM. Methods We conducted an ambispective multi-centric cohort study of clinical records available from patients with MM that were diagnosed in the most populated regions of Colombia. We collected demographic, diagnostic, clinical and treatment data at different time points from diagnosis to the most current follow up. The computerized de-identified data was consolidated and analyzed using basic statistical measures of central tendency and dispersion. The most current follow up included data available from last clinic visit, loss of follow up, death or withdrawal of consent. This study was approved by local and centralized institutional review board. Results We analyzed data from 206 MM patients (pts). Average age at diagnosis was 62.9 (SD 10.2) years and 51.4% of pts were male. Most common symptoms at diagnosis were bone pain (74.2%), anemia related (58.2%) and pathological fractures (45.1%). Mean time from symptoms to diagnosis was 7.3 (Range 1-44) months. Baseline mean hemoglobin, creatinine and calcium serum levels were 10.5 g/dL, 1.58 mg/dL and 9.2 mg/dL respectively. At diagnosis, 22% of patients presented with renal failure and 30% required dialysis. Immunoglobulin (Ig) subtype distribution was: IgG 50.6%, IgA 20.6%, only light chain secretion (61% Kappa) and IgM 1.1%. In 11.6% all Igs were low. Most pts were diagnosed at advanced stages (64.5% Durie-Salmon III, and 37% and 47% International Staging System II and III respectively). Molecular prognostic characterization was performed only in 39 patients (18.4%). Four patients were considered too fragile for active treatment. The most common initial treatment was triple combinations that included Bortezomib (84% of patients). Among those, CyBorD was the most frequently used first line therapy (58.3%), followed by VTD (14.6%). Mean number of cycles was 4.8 (SD 2.5). Overall Response Rate (ORR) 74.7% was observed. Only 40% of patients treated with intense induction therapy received autologous transplant. Response to treatment including transplant are shown in table 1. Second and further lines of treatment were highly variable. 18 patients were treated with a second autologous transplantation consolidating 2nd line therapy. 12 patients received Carfilzomib combinations, all of them in 2nd line. 5 patients were treated with Daratumumab, all >2nd line. Mean follow-up time was 33.53 (SD 3.6) months. After a median follow up of 27 months we observed in our cohort an overall survival of 82% and 68% of patients progression-free. . Conclusions This first report focusing on MM highlights important differences on patient's characteristics and treatment in Colombian patients. This includes and treatment initiation due to insurance barriers; high risk clinical characteristics and complications upon diagnosis and low rate of transplantation in patients otherwise eligible for this procedure. Rates of response to induction seem slightly lower than reported (CB Reeder 2009). However, overall survival and progression-free survival met the expectations for this type of patients. The development of country specific databases may influence the design of policies, allocation and use of resources and improve patient outcomes. Only cooperative efforts like the one spearheaded by RENEHOC can achieve those goals. Disclosures No relevant conflicts of interest to declare.
