CLL has a five-year survival rate of around 83%, although it drops under 70% in those over 75. Researchers base survival rates on information from people diagnosed with CLL 5 years before. These abnormal lymphocytes do not function as they should, impairing the bodys ability to fight infection. An 87% 5-year survival rate means that around 87 out of every 100 people with CLL will be alive 5 years after diagnosis. Hence, it is imperative to get information about individual patient prognosis in order to define a therapeutic strategy and to allow patients to plan their lives moving forward. Regarding CLL treatment, conventional therapy with alkylating agents has been used for a long time, which reported low- to non-existent complete remission rates and adverse events after prolonged use. These are very much chronic leukemias just as much as a chronic lymphocytic leukemia or a chronic myeloid leukemia. This statistic does not take treatments or responses to treatments into account and is not predictive of what will happen in your situation. Watchful waiting is not a passive treatment. Dhner H, Stilgenbauer S, Benner A, et al. This could be explained by the limited statistical power for detecting OS due to small number of observed patient deaths.

CLL Society Inc. is a patientcentric, physiciancurated nonprofit organization focused on patient education, support, and research. 52.1% of the patients with CLL harbored 13q deletion, which was significantly higher than that of other BCLPDs (p < 0.001). The anomaly is observed predominantly in older patients (average age 62.5 years; range 27-90). Lymphocytic leukemia begins in the white blood cells (WBC), known as lymphocytes. The site is secure. However, some patients experience treatment resistance or rapid relapses, and in particular, those harboring a 17p/TP53 deletion (del(17p)). Nupam A.
