Clinical Presentation, Progression, and Outcome of Patients With Clonal B-Cell Counts of Less Than 5 × 109/L, 5 to 10 × 109/L, and More Than 10 × 109/L and Chronic Lymphocytic Leukemia Immunophenotype

Presenting features and prognosis of B-cell chronic lymphocytic leukemia patients less than 50 years old.

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

CD38 expression in B-chronic lymphocytic leukemia: association with clinical presentation and outcome in 155 patients.

BACKGROUND AND OBJECTIVES To investigate whether CD38 expression at diagnosis is an independent predictor of survival and assess its associations with other clinical parameters used in the staging of B-cell chronic lymphocytic leukemia (B-CLL). DESIGN AND METHODS CD38 expression was analyzed in 155 consecutive unselected patients newly diagnosed with B-CLL from January 1991 to July 1997. In a...

Chronic lymphocytic leukemia B cells of more than 1% of patients express virtually identical immunoglobulins.

We examined the immunoglobulin (Ig) heavy chain variable region genes (V(H) genes) used by leukemia cells of 1220 unrelated patients with chronic lymphocytic leukemia (CLL). We found 1188 (97%) expressed Ig encoded by a single Ig V(H) subgroup, the most common of which was V(H)3 (571 or 48.1%), followed by V(H)1 (319 or 26.8%) and V(H)4 (241 or 20.2%). Using allele-specific primers, we found 13...
