It is rare for treatment to cure CLL, but it can successfully manage the condition. The .gov means its official. CD38, CD49d and Zap-70 are flow cytometry-based markers, however CD49d is more important than the other two, since it has an impact on prognosis independent of FISH tests or IGHV mutation status. Data doesnt currently indicate that a 20-year survival rate is common or likely with CLL.

Clonal diversity predicts adverse outcome in chronic lymphocytic leukemia. Since CLL doesnt usually cause tumors, it is not a standard therapy for this condition. Patients presenting with del13 abnormality as a sole chromosomal aberration usually have indolent biology, presentation and a long median survival. Figure 1. CLL starts in one of the types of white blood cells found in the bone marrow. This deletion leads to the loss of important microRNAs which are involved in maintaining the critical balance of the apoptosis mechanism of cell death of B lymphocytes.

Surgery: If you have an enlarged spleen that is causing symptoms such as pain, a splenectomy (removal of the spleen) may be recommended. If a person does have symptoms, they may include the following: There are two types of CLL. Moreover, research into the 13q14 deletion has also provided new insights into the molecular genetics and pathways that interact in such a way, making it possible to transform healthy cells into malignant cells in an entirely new fashion with a complete disregard to its original form, resulting in CLL.
