We aimed to explore the incidence rate gender and age distribution of leukemia in Nanjing using the leukemia database of the city. Results The average yearly incidence rate of leukemia was 3.68 105 during 2003 - 2007 in Nanjing. There were no significant difference in gender x2 3.266 p 0.05 or seasons x2 11.36 p 0.05 . The incidence rate was the highest in group aged 80 years 18.64 105 . AML accounted for approximately 36.8 of all leukemias. Conclusions The incidence rate of leukemia especially in the aged population was relatively high in Nanjing. Leukemia is the major malignant tumor in children. Therefore more attention should be paid to leukemia in children and the aged people. To the Editor Nanjing an ancient capital and the second largest city in southeast China enjoys a worldwide reputation for its long history and splendid culture.
