【Abstract】 To study the clinical application of bone marrow biopsy in pediatric patients with acute leukemia at chemotherapy. Bone marrow aspirates and biopsy specimens were taken at examination form 50 pediatric patients with acute leukemia, in cluding initial and relapsed cases,after 2 courses of induction treatment on day 6 An amount of Abnormol leukemic blast cell in bone marrow biopsy (MABA) were correlated with percentage of leukemic blast cell in marrow aspiration MBP, but there was not much correspondence between the two. Small amount of leukemic blast cell in biopsy was under 200/mm 2,while large amount was above 600/mm 2. The complete remission rate was all of 13 cases in small amount group,21/23 cases in moderate amount group,and 11/14 cases in large amount group.And outside 1 case because discarded therapy relapsed all cases in large amount group in six months. The difference among three groups were significant(P<0.05). The amount of Abnormol leukemic blast cell in bone marrow biopsy for evaluation of the rapeutic effectiveness and prognosis of acute leukemia, in particular relapsed refractery, were significant.更多还原
