JO - Hematological oncology VL - 34 IS - 4 SN - 0278-0232 CY - New York, NY [u.a.] PB - Wiley Interscience M1 - DKFZ-2017-01682 SP - 200 - 207 PY - 2016 AB - Therapeutic options in heavily pretreated relapsed/refractory multiple myeloma patients are often very limited because of impaired bone marrow function. Bendamustine is effective in multiple myeloma and has a favourable toxicity profile. We hypothesized that dose-intensified bendamustine (180 mg/m(2) , day 1 and 2) followed by autologous blood stem cell support (ASCS) would improve bone marrow function with low post-transplant toxicity in patients with severely impaired haematopoiesis. We analyzed 28 consecutive myeloma patients, with a median of three prior lines of therapy (range 2-7), who had relapsed from the last treatment with very limited bone marrow function and were therefore ineligible for conventional chemotherapy, novel agents or trial enrolment. Dose-intensified bendamustine with ASCS improved haematopoiesis as reflected by increased platelet counts (median 40/nl vs 94/nl, p = 0.0004) and white blood cell counts (3.0/nl vs 4.8/nl, p = 0.02) at day +100. The median time until engraftment of platelets (>50/nl) was 11 days (0-24 days) and of white cell counts (>1.0/nl) 0 days (0-24 days). At least, a minimal response was achieved in 36 KW - Bendamustine Hydrochloride (NLM Chemicals) LB - PUB:(DE-HGF)16 C6 - pmid:25784529 DO - DOI:10.1002/hon.2199 UR - https://inrepo02.dkfz.de/record/125556 ER -
