Perfil clínico-laboratorial e associação com fatores prognósticos de pacientes com leucemia linfocítica crônica

Abstract

Chronic Lymphocytic Leukemia is the primary lymphoid neoplasm in adults and and it is especially manifested in the elderly. Because it is a heterogeneous disease it awakens great interest regarding its prognosis. Rai and Binet developed staging systems to predict the evolution of the disease and currently, the analysis of expression of CD38 and Zap-70 has been investigated as a prognostic factor for indicating presence or absence of the mutation in the gene IgVH, so, the objective of this study was to analyze the clinical and laboratory profiles of patients with Chronic Lymphocytic Leukemia taking as reference the clinical staging of Rai and Binet and quantification of CD38 and Zap-70 expression as prognosis factors. We searched the medical records of 64 patients treated at University Hospital of Santa Maria and the variables considered were swollen lymph nodes, presence or absence of hepatomegaly and / or splenomegaly, hematological evaluation of peripheral blood and immunophenotype. The data obtained were correlated with the staging of Rai (1975) and Binet (1981), the expression of CD38 and Zap-70 and clinical stage. The results showed no association between ataging Rai and Binet and the expression of CD38, Zap-70 and Binet clinical staging.
