Prospective Collection of Biological Data of Prognostic Relevance in Patients With B-Cell Chronic Lymphocytic Leukemia
Study Details
Study Description
Brief Summary
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.

Detailed Description
Clinical data including information on disease localization and laboratory parameters will be collected at study entry, during follow up and at disease progression (or after 36 months after registration) Biological markers will be evaluated at centralized laboratory, at study entry and at time of disease progression (or after 24 months of follow-up for non progressed patients) Using the scoring system, patients can be separated into 3 risk groups: low-risk (score 0), intermediate-risk (score 1) and high-risk (score 2-3), with significantly different clinical courses.

Outcome Measures
Primary Outcome Measures
- Prospective validation of the prognostic potential of a score system based on the presence/absence of three risk factors (VH mutational status, Zap-70 and CD38 expression) on Progression Free Survival (PFS ). [6 months]
Secondary Outcome Measures
- Quality of Life [6 months]
- Time to Treatment [6 months]
- Overall Survival [3 years]
Eligibility Criteria
Criteria
Inclusion Criteria:
