(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.

The prognosis is poor for relapsed or refractory (R/R) classical Hodgkin Lymphoma (cHL) patients. The brentuximab vedotin (Bv) and bendamustine (B) combination has been used as a preferable salvage regimen in R/R cHL patient trials. We retrospectively evaluated response rates, toxicities, and the survival in R/R cHL patients treated with the BvB combination. In a multi-centre real-life study, 61 R/R HL patients received intravenous doses of 1.8 mg/kg Bv on the first day plus 90 mg/m(2) B on the first and second days of a 21-day cycle as a second-line or beyond-salvage regimen. Patients' median age at BvB initiation was 33 (range: 18-76 years). BvB was given as median third-line treatment for a median of four cycles (range: 2-11). The overall and complete response rates were 82% and 68.9%, respectively. After BvB initiation, the median follow-up was 14 months, and one- and two-year overall survival rates were 85% and 72%, respectively. Grade 3/4 toxicities included neutropenia (24.6%), lymphopenia (40%), thrombocytopenia (13%), anaemia (13%), infusion reactions (8.2%), neuropathy (6.5%), and others. The BvB combination could be given as salvage regimen aiming a bridge to autologous stem cell transplant (ASCT), in patients relapse after ASCT or to transplant-ineligible patients with manageable toxicity profiles.

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.
