    Autologous Hematopoietic Progenitor Cell Mobilization and Collection in Adult Patients Presenting with Multiple Myeloma and Lymphoma: A Position-Statement from The Turkish Society of Apheresis (TSA)
    (2017) Tekgunduz, Emre; Arat, Mutlu; Goker, Hakan; Ozdogu, Hakan; Kaynar, Leylagul; Cagirgan, Seckin; Erkurt, Mehmet Ali; Vural, Filiz; Kiki, Ilhami; Altuntas, Fevzi; Demirkan, Fatih; https://orcid.org/0000-0002-8902-1283; 29153306; AAD-5542-2021
    Autologous hematopoietic cell transplantation (AHCT) is a routinely used procedure in the treatment of adult patients presenting with multiple myeloma (MM), Hodgkin lymphoma (HL) and various subtypes of non-Hodgkin lymphoma (NHL) in upfront and relapsed/refractory settings. Successful hematopoietic progenitor cell mobilization (HPCM) and collection are the rate limiting first steps for application of AHCT. In 2015, alinost 1700 AHCT procedures have been performed for MM, HL and NHL in Turkey. Although there are recently published consensus guidelines addressing critical issues regarding autologous HPCM, there is a tremendous heterogeneity in terms of mobilization strategies of transplant centers across the world. In order to pave the way to a more standardized HPCM approach in Turkey, Turkish Society of Apheresis (TSA) assembled a working group consisting of experts in the field. Here we report the position statement of TSA regarding autologous HPCM mobilization strategies in adult patients presenting with MM and lymphoma. (C) 2017 Elsevier Ltd. All rights reserved.

    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.

    Extracorporeal Photopheresis In The Treatment Of Acute And Chronic Graft-Versus-Host Disease: A Position Statement From The Turkish Society Of Apheresis (TSA)
    (2022) Kaynar, Leylagul; Tekgunduz, Emre; Kozanoglu, Ilknur; Ozkan, Hasan Atilla; Aksu, Salih; Ozkalemkas, Fahir; Demirkan, Fatih; 35123893; GXH-4007-2022
    Graft versus host disease (GVHD) is still the most important cause of mortality and morbidity after allogeneic stem cell transplantation. Though perfect response rates are not achieved, steroids are still the first-line treat-ment. In the face of the presence of the drugs approved by FDA in recent years for acute and chronic GVHD as second-line therapy in the steroid-refractory group, there exists no standard approach. Extracorporeal photopheresis (ECP) with an immunomodulatory effect, is favored in the treatment of both acute and chronic steroid refractory GVHD as it does not increase the risk of relapses or infections. Having a low profile of side effects, ECP is also generally well-tolerated by patients. Being a time requiring procedure, the fact is that it is not able to be practiced in all health centers and requires central venous catheters in patients unfit for venous access may be enumerated among its shortcomings. No complete standard is available with respect to ECP application frequency-time; it varies from one center to another. The Turkish Society of Apheresis established the Turkish ECP (TECP) group and sought some answers to the questions regarding the use of ECP in the treatment of GVHD, and issued a position statement.
