Abstract:
Objective To explore the chromosome kauotype characteristics and the relationship with curative effect in the acute lymphoblastic leukemia (ALL).Methods The bone marrow cells were collected using a short-term culture method.The R banding technique of chromosome karyotype analysis was used in 80 cases of ALL patients.Results Normal karyotype were found in 53 cases (66.2 ％),and abnormal karyotype in 27 cases (33.8 ％),including structure of chromosome karyotype in 10 cases (12.5 ％),chromosome numerical abnormality in 2 cases (2.5 ％),abnormal complex karyotype in 15 cases (18.8 ％).According to the classification number of distortion,it was found that ＞ 50 diploid in 2 cases (2.5 ％),47-50 diploid in 5 cases (6.25 ％),false diploid in 18 cases (22.5 ％),normal diploid in 53 cases (66.25 ％),the diploid in 2 cases (2.5 ％),it did not shown any karyotype was triploid or nearly four times.The curative effect of normal karyotype was superior to that of the abnormal karyotype (x2 =19.371,P ＜ 0.01),that of complex karyotype had poorer than that of other karyotype (x2 =9.145,P =0.004),and patients accompaning with the t(9;22)(q34;q11) had poorer than that of other karyotype (x2 =5.785,P =0.021).Conclusions The abnormal chromosome karyotype is random.More common abnormal karyotype is complex karyotype and t(9;22) (q34;q11),which curative effects are poorer.
