Natural History Study of Monoclonal B Cell Lymphocytosis and Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
-The development of new technologies now allow scientists to investigate the genetic basis of monoclonal B cell lymphocytosis (MBL) and chronic lymphocytic leukemia(CLL)/Small lymphocytic lymphoma (SLL) and their clinical manifestations. Applying these methods in a natural history study can clarify processes involved in disease progression and possibly lead to the discovery or validation of treatments.
- To describe the natural course of MBL and CLL/SLL in patients before they need treatment.
- To characterize in each patient the clinical, biologic and molecular events of disease stability and progression.
-Patients 18 years of age or older diagnosed with either MBL or CLL/SLL.
- Patients are followed every 3 to 12 months with tests that may include bone marrow biopsy and aspiration, blood drawing, lymph node biopsy, x-ray studies, positron emission tomography and CT scans of the neck, chest, abdomen, and pelvis. Because these tests are routinely done to monitor MBL and CLL/SLL, participants need not undergo additional tests specifically for research. (Bone marrow biopsy and aspiration and lymph node biopsy are often not required to diagnose CLL/SLL, but patients may be asked to undergo these procedures for research purposes in this study.)
- Clinical information is collected and stored in a central databank.
- Patients whose cancer requires treatment will be taken off the study and treatment options will be discussed with them. If no NIH treatment protocols are available to them, they will be returned to the care of their local physician.

|Study Design:||Time Perspective: Prospective|
|Official Title:||Natural History Study of Monoclonal B Cell Lymphocytosis (MBL) and Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL)|
|Study Start Date:||April 2008|
The purpose of this protocol is to collect blood, tissue (bone marrow and lymph node biopsies) and/or imaging studies (PET and CT scans) from patients with monoclonal B cell Lymphocytosis (MBL) and chronic lymphocytic leukemia/small lymphoma (CLL/SLL)
Assessments will be used for clinical and translational research investigating the molecular basis of Monoclonal B cell lymphocytosis (MBL) and Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) and their clinical manifestations. New technologies now permit the simultaneous characterization of pathogenic events ranging from the control of gene expression to the characterization of the molecular events of cell-cell interactions. Applying these methods to MBL/CLL/SLL in the context of a natural history protocol can help unravel cellular pathways involved in pathogenesis and disease progression and lead to the discovery or the validation of therapeutic targets. MBL/CLL/SLL is an incurable disease for which there are no cell lines and only a few mouse models. There is an urgent need to obtain a flow of primary samples to advance research into pathogenesis and novel treatment approaches.
- Diagnosis of MBL/CLL/SLL
- Age greater than or equal to 18 years.
- Patients must have received no previous cytotoxic or monoclonal antibody therapy for CLL/SLL.
- ECOG performance status of 0-2.
-Patients will be followed as needed and clinically indicated; typically this will include visits between every 3-24 months. Patients may donate cellular products or tissues as appropriate for research purposes. Clinical information will be obtained and stored in a central databank.
- Describe the natural history of MBL/CLL/SLL in patients prior to the time when their disease requires treatment.
- Apply the expertise and available technologies of the investigators to advance our understanding of disease pathogenesis and develop novel treatment approaches for CLL/SLL.
- Provide evaluation, diagnostic studies and monitoring for patients on study.
- Provide blood and tissue linked to clinical and biologic information for translational studies.
-Progression free survival, measured as the time from diagnosis to the development of active disease that requires treatment at which tie patients will be able to change to a treatment protocol or seek treatment outside of NIH.
