These are very much chronic leukemias just as much as a chronic lymphocytic leukemia or a chronic myeloid leukemia. This means that a person must live with the disease and is likely to need ongoing treatment. ~Del (11q) is a high-risk chromosomal aberration; its incidence increases over time, thus highlighting the need to test for it at diagnosis, as well as at clinical progression. Whereas 13q deletion was a favorable prognostic factor in CLL, a large deletion of 13q was associated with poor prognosis in terms of time to first therapy (p = 0.020), progression-free survival (p = 0.05) and overall survival (p = 0.002) in BCLPD cases other than CLL. CLL has a higher survival rate than many other types of cancer.

The cells for each form are slightly different, but doctors can only tell them apart by testing them in a laboratory. 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. This segment encodes several proteins that regulate cell proliferation and the cell cycle, such as SMAD9 and RB1; both are involved in the signal transduction pathway of transforming growth factor-beta (TGF-, an important .
