Granulocyte colony-stimulating factor (G-CSF) is the most prevalently used growth for peripheral blood hematopoietic stem cell (HSC) mobilization. Most centers split granulocyte in two daily doses, whereas some administer one dose per day. This study aims to investigate effect of filgrastim dosing schedule on quantity cells collected after mobilization healthy donors. A total 251 donors mobilized our center were included study. Mobilization was either once a day (filgrastim 1 × 10 mg/kg/day)...

The prognosis is poor for relapsed or refractory (R/R) classical Hodgkin Lymphoma (cHL) patients. 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, the survival patients treated with BvB combination. In multi-centre real-life study, 61 HL received intravenous doses of 1.8 mg/kg Bv on first day plus 90 mg/m2 B second days 21-day cycle second-line...

A multicenter, retrospective, observational study was conducted to explore effectiveness and safety of ixazomib plus lenalidomide with dexamethasone (IRd) in relapsed/refractory multiple myeloma (RRMM) patients following at least ≥ two lines therapy. Patients' treatment responses, overall response rate, progression-free survival adverse events were recorded. Mean age 54 66.5 ± 9.1 years. There 20 (37.0%) progression. Median 13 months who received a median three therapy 7.5-month follow-up...

Gemcitabine, dexamethasone and cisplatin (GDP) is a well-established salvage regimen for relapsed refractory lymphomas. In this study, we aimed to share our experience with the patients who received GDP/R-GDP (rituximab-gemcitabine, cisplatin) stem cell mobilization.Data of 69 Hodgkin lymphoma (HL) Non-Hodgkin (NHL) as chemotherapy in center between July 2014 January 2020 were retrospectively evaluated. After evaluation response, 52 had chemosensitive disease underwent mobilization plus...

: The Wilms' tumor gene 1 (WT1) plays a critical role in cell development and the regulation of essential genes involved growth metabolism. In context hematopoietic tumors, including acute myeloid leukemia (AML), WT1 has been identified as potential marker for measurable residual disease (MRD) assessment. Relapse after allogeneic stem transplantation (allo-SCT) remains significant challenge AML treatment, highlighting importance MRD monitoring risk stratification treatment decisions. This...

Abstract Rationale: Relapsed or refractory peripheral T-cell lymphomas are aggressive diseases. Pralatrexate is an antimetabolite. Hereby, we reporting a pralatrexate induced durable response in relapsed/refractory T-Cell lymphoma patient with history of autologous stem cell transplantation. Patient concerns: A male born February 1947 was diagnosed based on his cervical lymph node excisional biopsy. Diagnoses: He PTCL-NOS 19, 2013. Interventions: The received 6 cycles CHOP (Cyclophosphamide,...

We report a 42-year-old patient who had Hodgkin lymphoma and developed bilateral symmetrical peripheral gangrene (SPG) in the feet hands, which occurred during septic shock after autologous hematopoietic stem-cell transplantation. SPG is rare but severe complication of disseminated intravascular coagulation (DIC) frequently associated with sepsis. The pathophysiology includes DIC-mediated thrombosis thrombotic occlusion microcirculation, resulting low blood flow. Sepsis-induced hypotension...
