Efficiency of day 4 compared to day 6 stem cell mobilization in allogeneic stem cell donors.

Background: Granulocyte colony stimulating factor (G-CSF) given for 4-6 days is commonly used for mobilization of allogeneic stem cell donors. The primary objective of this study is to compare the yield of stem cell mobilization, assessed using a surrogate endpoint of CD34 cell count, between Day 4 and Day 6.

Study Design And Methods: In this retrospective study we included all allogeneic stem cell donors mobilized with G-CSF for 6 days from January 2003 until October 2015 in the bone marrow transplantation unit at a tertiary academic center.

Immunophenotypic Characteristics of T-Acute Lymphoblastic Leukemia in Omani Patients: A Correlation with Demographic Factors.

Objectives: To study and classify the immunophenotypic characteristics of Omani patients diagnosed with T-cell acute lymphoblastic leukemia (T-ALL) and to correlate the results with age and gender as well as biological factors (peripheral and bone marrow blast cells percentage).

Methods: Fifty cases from both genders and of all ages who fulfilled the inclusion criteria with a diagnosis of T-ALL were included in the study. Correlation of T-ALL subtypes with age, gender, and initial bone marrow and peripheral blood blast cells percentage was assessed using ANOVA.
