Prospective Collection of Biological Data of Prognostic Relevance in Patients With B-Cell Chronic Lymphocytic Leukemia

The purpose of the present study is to develop a biological prognostic index in patients with Binet stage A Chronic Lymphocytic Leukemia (CLL) who do not necessitate therapy according to NCI guidelines and to prospectively validate the proposed score system based on the absence/presence of 1, 2 or 3 unfavorable prognostic markers such as cluster of differentiation 38 (CD38) expression, Zap-70 expression and immunoglobulin heavy chain variable region (IgVH) configuration.

Sex

All

Minimum age

18 Years

Maximum age

80 Years

Inclusion Criteria:

* Established diagnosis of B-CLL by NCI criteria, performed by local haematologist. (Diagnosis will be confirmed by the biological review committee according to flow cytometry analysis (positive clusters of differentiation antigen 5 (CD5), 19 (CD19),23 (CD23)).
* Age \> 18 years and \< 70 years.
* Eastern Cooperative Oncology Group (ECOG)\<=2.
* Binet stage A.
* Diagnosis performed within 12 months before inclusion in the study.
* Patients who do not necessitate therapy by NCI guidelines (watch and wait policy).
* Shipment of peripheral blood sample to centralized laboratory for biological assessment.
* Clinical data including baseline information on disease localization and laboratory parameters at staging and assurance of follow up updating for at least 3 years are requested.
* Written informed consent.

Exclusion Criteria:

* Patients with CLL whose diagnosis exceed 12 months before registration.
* Patients with leukemic phase of lymphoproliferative disorders of B origin CD5- and/or CD23- according to flow cytometry analysis.
* Clinical Binet stage B or C.
* Patients who necessitate therapy according to NCI guide-lines (no watch and wait policy).
* Age \> 70 years.
* Without a written informed consent.
