Demographic characteristics of patients with leukemia waiting for stem cell transplantation in Chinese Marrow Donor Program during 2000 to 2006 / 中华预防医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the distributive characteristics for leukemia and to provide scientific reference for its prevention and intervention.</p><p><b>METHODS</b>Microsoft SQL 2005 databases was used to make a mathematical analysis of 3708 patients with leukemia in Chinese Marrow Donor Program (CMDP) from 2000 to 2006. The distributive characteristics were calculated by sex, age and area of patients with leukemia and then compared by constituent ratio and relative ratio statistics method.</p><p><b>RESULTS</b>A total of 3708 cases of leukemia were registered for waiting donor during the period 2000-2006 in CMDP, the age of patients were from 7 months to 69 years, the median age of diagnosis was 24.5 years, standard deviation was 6.7-years-old; males suffered more than females, and the ratio was 1.95 1 (2451/1257). There were 1202 patients with acute lymphoblastic leukemia (ALL), 1066 with acute myeloid leukemia (AML), 1435 with chronic myeloid leukemia (CML), 5 with chronic lymphoblastic leukemia (CLL), CML was the most common patients. The distributive of 3708 patients with leukemia peak was from 15 to 30 years age group, 542 patients were at the age of 15 years, 559 patients were at the age group above 20 years, 514 patients were at the age above 25, 522 patients were at the age over 30-years-old. ALL patients were accounted for 49.36% (613/1242), AML patients accounted for 27.78% (245/1242), CML patients accounted for 22.78% (283/1242), CLL patients accounted for 0.08% (1/1242) in the age group of under 20 years (childhood group). All subjects were mainly in childhood patients with leukemia; The distributive of patients with leukemia in 30 areas were different, leukemia patients were not registered in one area, 494 patients were at the highest peak, 101 patients were in the median.</p><p><b>CONCLUSION</b>The majority of leukemia patients for waiting stem cell transplantation were registered among children and the adolescents groups, males were suffered more than the females. For children, the major type of leukemia was ALL, being necessary to pay more attention to the education of health, and the precaution of leukemia. The distributive of patients with leukemia for waiting stem cell transplantation was different in 30 areas, and the peak region of leukemia should be in Jiangsu, Guangdong, Shangdong, and Zhejiang provinces.</p>
