    Autologous hematopoietic cell transplantation (AHCT) is an established treatment option for adult patients presenting with multiple myeloma (MM), Hodgkin lymphoma (HL) and various subtypes of non-Hodgkin lymphoma (NHL) in upfront and/or relapsed/refractory disease settings. Although there are recently published consensus guidelines addressing critical issues regarding autologous hematopoietic progenitor cell mobilization (HPCM), mobilization strategies of transplant centers show high variability in terms of routine practice. In order to understand the current institutional policies regarding HPCM in Turkey and to obtain the required basic data for preparation of a national positional statement on this issue, Turkish Hematology Research and Education Group (ThREG) conducted a web-based HPCM survey. The survey was designed to include multiple-choice questions regarding institutional practice of HPCM in adults presenting MM, HL, and NHL. The representatives of 27 adult HCT centers participated to the study. Here we report the results of this survey shedding light on the real world experience in Turkey in terms of autologous HPCM mobilization strategies in patients presenting with MM and lymphoma.

    Impact of COVID-19 on Outcomes of Patients with Hematologic Malignancies: A Multicenter, Retrospective Study
    (2022) Acar, Ibrahim Halil; Guner, Sebnem Izmir; Aslaner Ak, Muzeyyen; Gocer, Mesut; Ozturk, Erman; Atalay, Figen; Sincan, Gulden; Yikilmaz, Aysun Senturk; Ekinci, Omer; Ince, Idris; Gulturk, Emine; Demir, Nazli; Dogan, Ali; Ipek, Yildiz; Guvenc, Birol; https://orcid.org/0000-0003-4384-2913; 36425152
    Objectives: Patients with hematological malignancies have a high risk of mortality from coronavirus disease 2019 (COVID-19). This study aimed to investigate the impact of COVID-19 on mortality rates in patients with various hematological malignancies and to determine risk factors associated with all-cause mortality.Methods: A multicenter, observational retrospective analysis of patients with hematological malignancies infected with COVID-19 between July 2020 and December 2021 was performed. Demographic data, clinical characteristics, and laboratory parameters were recorded. Patients were grouped as non-survivors and survivors. All-cause mortality was the primary outcome of the study.Results: There were 569 patients with a median age of 59 years. Non-Hodgkin lymphoma (22.0%) and multiple myelomas (18.1%) were the two most frequent hematological malignancies. The all-cause mortality rate was 29.3%. The highest mortality rates were seen in patients with acute myeloid leukemia (44.3%), acute lymphoid leukemia (40.5%), and non-Hodgkin lymphoma (36.8%). The non-survivors were significantly older (p<0.001) and had more comorbidities (p<0.05). In addition, there were significantly more patients with low lymphocyte percentage (p<0.001), thrombocytopenia (p<0.001), and high CRP (p<0.001) in the non-survived patients. Age >= 65years (p=0.017), cardiac comorbidities (p=0.041), and continuation of ongoing active therapy for hematological cancer (p<0.001) were the independent risk factors for the prediction of mortality.Conclusions: In patients with hematological malignancies, coexistent COVID-19 leads to a higher mortality rate in elderly patients with more comorbidities. Acute myeloid and lymphoid leukemia and non-Hodgkin lymphoma have the highest mortality rates. Older age, cardiac diseases, and continuation of ongoing active therapy for hematological cancer are the independent risk factors for mortality in hematological malignancy patients with COVID-19.
