ABSTRACT
Objective To explore the features of patients with acute leukemia (AL) in Hematology Department of Shenzhen Hospital affliated to Beijing University during the past six years. Methods The data of the 1056 acute leukemia dignosed in our department between 2002-2007 were collected and analyzed retrospectively. Results The male patients was predominant (male/female ratio was 1.78). The number of patients with acute myeloid leukemia(AML) was higher than that of patients with acute lymphoblastic leukemia (ALL) (AML/ALL ratio was 1.85). Most of the AML patients were young adult (65 %) and elderly ALL patients were very rare(1.33 %). AL cases were tended to increase gradually by year. The ratio of treatment-related AL in Shenzhen was lower than that reported literature in other countries. The major cause of the treatment-related AL were chemotherapy/radiotherapy and psoriasis treated with bimolane. Conclusion Some of the features of AL patients in China were further confirmed and some new features were also found in this study. These changes should be demonstrated by the next national epidemiology survey of leukemia.
