No leucsmia exist as yet to suggest any harm with a delay in therapy until the patient becomes symptomatic or develops serious cytopenias despite growth factor support. Computed tomographic CT scans have a very limited role in following patients after completion of treatment; the decision to treat for relapse was determined by CT scan or ultrasound in only 2 of patients in three prospective trials for the German CLL Study Group.

¿Cuáles son los factores de riesgo de la leucemia linfocítica crónica?

In a database analysis and for up to 77 months before diagnosis, almost all patients with a diagnosis of CLL had prediagnostic B-cell clones that were identified in peripheral blood when available.

The improvements in response rates from more intensive regimens have maximized the clearance of MRD. Refer to the Prognostic Factors section in the Stage Information for Chronic Lymphocytic Leukemia section of this summary for more information. Second malignancies and treatment-induced acute leukemias may also occur in a small percentage of patients.

The necessary study would include patients who fail to completely clear the marrow with induction therapy and randomly assign them to further alternative treatment versus the same treatment later at relapse, looking at OS as the primary endpoint.

A group of experts from the Spanish Chronic Lymphocytic Leukemia Group reviewed all published literature from January to Januaryin order to provide recommendations based on clinical evidence.

Stage I CLL is characterized by absolute lymphocytosis with lymphadenopathy without hepatosplenomegaly, anemia, or thrombocytopenia. In a randomized prospective study, previously treated patients received intravenous alemtuzumab plus fludarabine versus fludarabine alone. A population-based analysis of almost 2 million cancer patients in the National Cancer Institute’s Surveillance, Epidemiology, and End Results SEER database suggests that cancer-specific survival for patients with pre-existing CLL who subsequently develop colorectal and breast cancer is significantly lower hazard ratio [HR], 1.

A National Cancer Institute NCI -sponsored working group has formulated standardized guidelines for criteria related to eligibility, response, and toxic effects to be used in future clinical trials in CLL. Permission to use images outside the context of PDQ information must be obtained from the owner s and cannot be granted by the National Cancer Institute. May Pages In one prospective trial of patients, clearance of MRD was an independent predictor of overall survival OS by multivariate analysis.

Patients with adverse prognostic factors are very likely to die from CLL. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field.


With a median follow-up of 9. Purine analogs cause less hair loss lehcemia nausea than combination chemotherapy, including alkylators and anthracyclines. There are many controversial issues in the management of CLL with no appropriate studies for making consensus recommendations.

SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact. Because of the indolent nature of stage 0 chronic lymphocytic leukemia CLLtreatment is not indicated. New prognostic markers are now available to the clinician and investigator. Patients with CLL are also at increased risk for other malignancies, even before therapy.

From Monday to Friday from 9 a. CiteScore measures average citations received per document published. Prolymphocytic leukemia PLL is a rare entity characterized by excessive prolymphocytes in the blood with a typical phenotype that is positive for CD19, CD20, and surface-membrane immunoglobulin and negative for CD5.

Use of these systems allows comparison of clinical results and establishment of therapeutic guidelines. A prospective, randomized trial of patients who were previously untreated compared ofatumumab plus chlorambucil with chlorambucil alone. In asymptomatic patients, treatment may be deferred until the patient becomes symptomatic as the disease progresses. Print Send to a friend Export reference Mendeley Statistics.

Board members will not respond to individual inquiries. The French Cooperative Group on CLL randomly assigned 1, patients with previously untreated stage A disease to receive either chlorambucil or no immediate treatment and found no survival advantage for chlorambucil. Continuing navigation will be considered as acceptance of this use.

CLL B cells express relatively low levels of surface-membrane immunoglobulin compared with normal peripheral blood B cells and a single light chain kappa or lambda. Its major benefit derives from the recognition of a predominantly splenic form of the disease, which may have a better prognosis than in the Rai staging, and from recognition that the presence of anemia or thrombocytopenia has a similar prognosis and does not merit a separate stage.


This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the treatment of chronic lymphocytic leukemia. The project has resulted in several practical recommendations that will facilitate the diagnosis, treatment, and follow-up of patients with CLL.

All articles are subjected to a rigorous process of revision in pairs, and careful editing for literary and scientific style. In the absence of randomized trials comparing the new B-cell receptor inhibitors and bcl-2 inhibitors to the new monoclonal antibodies and to more conventional chemotherapeutic agents, the following general principles may provide a sequencing for available therapeutic options:.

It does not provide formal guidelines or recommendations for making health care decisions. The Binet classification integrates the number of nodal groups involved with the disease with bone marrow failure. These references have been identified by members of the PDQ Adult Treatment Editorial Board as significant in the field of chronic lymphocytic leukemia treatment. This section describes the latest changes made to this summary as of the date above.

These designations are intended to help readers assess the strength of the evidence supporting the use of specific interventions or approaches. The French Cooperative Group on CLL randomly assigned 1, patients with previously untreated stage A disease to receive either chlorambucil or no immediate treatment and found no survival advantage for prolijfocitica treatment with chlorambucil.

Patients who received obinutuzumab did not have improved survival compared with those who prolinfociyica rituximab alone. These patients often have neutropenia and a history of rheumatoid arthritis. Listed after each reference are the sections within this summary where the reference is cited.
