Incidence of leukemia in infants in Shanxi Children's Hospital / 白血病·淋巴瘤

ABSTRACT

Objective To investigate the incidence of leukemia in infants, and to understand the status of this disease in recent years. Methods A total of 5802 children aged median 6 years (0-12 years) with first time bone marrow biopsy from January 2009 to December 2015 were retrospectively analyzed, and the results of bone marrow image analysis were analyzed retrospectively to investigate the incidence of leukemia. Results Of the 5802 cases, 480 (8.27 %) cases were children with leukemia. Among them, 381 (79.38 %) cases were acute lymphocytic leukemia (ALL), 99 (20.62 %) cases were acute myeloid leukemia (AML). The proportion of children with leukemia with first time marrow puncture was 5.33%(40/750), 4.92%(36/731), 7.06%(58/821), 8.34%(78/935), 10.13%(88/868), 10.89%(92/845), and 10.33%(88/852) from 2009 to 2015, respectively. The proportion of male patients per year was more than female, and the incidence in preschool and school-age children was higher [33.75 % (162/480) and 34.79 % (167/480), respectively]. Conclusion The proportion of children's leukemia in children with the first time bone marrow aspiration in Shanxi Children's Hospital increases year by year, and its risk factors need to be further analyzed.
