Summary

Chronic lymphocytic leukemia (CLL) is a highly heterogeneous B-cell hematological malignancy characterized by clonal expansion and accumulation of morphologically mature B-lymphocytes with a peculiar immunophenotype in peripheral blood, bone marrow, and secondary lymphoid tissues. Diagnosis is usually possible by flow cytometry, while lymph node and/or bone marrow biopsy may be helpful if immunophenotyping is inconclusive. A better understanding of pathogenesis has, recently, allowed the identification of new markers, improving patient stratification, implementing the therapeutic armamentarium with new agents targeting key intracellular signaling pathways. The canonical Wnt/β-catenin pathway is well recognized and known to drive malignant transformation of several cancer types including B-CLL. High expression of WNT3 and its transcription factor LEF1 in CLL considered as one of the strongest facts supporting the role of this pathway in CLL.

The evaluation of LEF-1 expression by immunohistochemistry in the diagnostic setting is still limited and a substantial number of CLL patients with negative LEF-1 expression has been reported. This is a study of LEF-1 expression to test the utility of using it for optimizing the B-CLL diagnosis and correlate it with the immunohistochemical, clinical and molecular data and compare LEF-1 negative and positive cases to identify a possible LEF-1 expression related signature that could be useful in differential diagnosis, in prognostic stratification and possibility of using targeted drugs
