<prompt> B cell prolymphocytic leukemia patients differ from those with B cell chronic lymphocytic leukemia in -Presenting at a younger ageHaving a lower total leucocyte countHaving prominent lymphadenopathyHaving a shoer survival  <response>: cell prolymphocytic leukemia B-PLL is a very rare B cell neoplasm comprised of so-called prolymphocytes, typically with involvement of the peripheral blood, bone marrow, and spleen. The name prolymphocyte is actually a misnomer, as the tumor cells in this disease are mature activated B cells The 5-year survival rate for people age 20 and older with CLL is 84. It is impoant to remember that statistics on the survival rates for people with leukemia are an estimate. B-cellchronic lymphocytic leukaemia CLL develops from a type of white blood cell called B cells. It progresses slowly, usually affecting older adults. Survival rate for chronic lymphocytic leukemia CLL has a higher survival rate than many other cancers. The five-year survival rate is around 83 percent. This means that 83 percent of people with the condition are alive five years after diagnosis Ref Davidson 23rd edition pg 926-927
