Clinicoepidemiological features of adult leukemias in Pakistan

A total of 113 patients of leukemia, over 15 years of age, were seen in three different institutions from July, 1992 to June, 1994. There was an almost equal distribution of acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) (44 vs 43 cases respectively). Chronic lymphocytic leukemia (CLL) was the least common, accounting for 5% of all cases. Mean age in CLL was 59 years. Chronic myeloid leukemia (CML) was three times commoner than CLL with a younger age distribution (median age was 34 years). We conclude that the clinicoepidemiological features of adult leukemias differ considerably from that seen in the developed world. However, recruitment of patients needs to continue in order to define these features based on a larger patient population.
