Survival rates for most childhood cancers have improved, with a notable improvement in acute lymphoblastic leukemia (the most common childhood cancer). Due to improved treatment, the 5-year survival rate for acute lymphoblastic leukemia has increased from less than 10% in the 1960s to about 90% during the time period 2003-2009. [16]
The most common T-cell leukemia is precursor T-cell lymphoblastic leukemia. [1] It causes 15% of acute leukemias in childhood, and also 40% of lymphomas in childhood. [1] It is most common in adolescent males. [1] Its morphology is identical to that of precursor B-cell lymphoblastic leukemia. [1] Cell markers include TdT, CD2, CD7. [1]
