This international questionnaire survey aimed to explore the current incidence, diagnostic policies, management, and outcomes of veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) among healthcare providers involved in the management of these patients. A questionnaire was e-mailed to practitioners with an interest in allogeneic hematopoietic cell transplantation (allo-HCT). Of the respondents, 144 of 215 (67.0%) felt that early detection or diagnosis of VOD/SOS was difficult. Regarding diagnostic criteria, 142 (66.1%) already declared using the 2023 EBMT refined criteria. Most respondents (163/215, 75.8%) found these recent refined EBMT criteria useful for diagnosis, and 193 (89.8%) found the severity criteria easy to use. The major risk factors identified for VOD/SOS were a second allo-HCT (41.4%), pre-existing liver disease (54.9%), and prior use of antibody-drug conjugates (49.8%). Preferences for starting VOD/SOS treatment varied, with 61 (28.4%) preferring initiating therapy at a mild stage, and 122 (56.7%) preferring the moderate stage. In summary, this survey provided valuable insight into the challenges and opportunities of the identification and management of VOD/SOS. By improving current knowledge and increasing collaboration among healthcare professionals, early detection, management, and clinical outcomes for patients with this potentially serious complication can also be improved., (© 2024.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a widely utilized treatment for various hematological diseases. While selection criteria for unrelated donors are well established, there is a lack of consistency and standardization in the selection of related donors. This study investigated the current approach of hematologists to the selection of related donors at Turkish HSCT centers. The study employed a cross-sectional survey design, distributing a self-administered questionnaire to 95 adult and pediatric transplantation centers in Türkiye to investigate their approaches to related donor selection for allo-HSCT. The questionnaire collected data on various topics including the center’s experience in performing allo-HSCT, patient groups treated, number of allo-HSCT procedures conducted between 2015 and 2021, preferences for related donors, considerations in related donor selection (such as sex and past pregnancies), guidelines utilized for related donor selection, upper age limit for related donors, and the use of specialized advanced analyses for elderly donors. The response rate to the survey was 38.9%. Variability was observed across centers in terms of sex consideration and the impact of past pregnancies on related female donor rejection. Different guidelines were employed for related donor selection, with the European Bone Marrow Transplantation guidelines being the most commonly used. Regarding the upper age limit for related donors, 8.1% of centers accepted an upper age limit of 55 years, 48.7% preferred an upper age limit of 65 years, and 43.2% selected related donors aged 65 and above. The lack of standardized guidelines for related donor selection in HSCT centers leads to variability in criteria and potential risks. Collaboration among centers is essential to establish consensus and develop standardized protocols., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (©Copyright 2024 by Turkish Society of Hematology Turkish Journal of Hematology, Published by Galenos Publishing House.)
