pubmed:abstractText |
Cytogenetic analysis was performed on 105 children with acute lymphoblastic leukemia (ALL). Adequate mitoses for study were obtained in 79 of the cases (71%). A normal karyotype was found in 18 patients (23%), while clonal chromosomal abnormalities were detected in 61 patients (77%). The karyotypes fell into five categories according to modal number: normal (18 patients), pseudodiploid (27 patients), hypodiploid (3 patients), hyperdiploid with 47-50 chromosomes (11 patients), and hyperdiploid with greater than or equal to 51 chromosomes (20 patients). Structural chromosome changes were found in 50 patients (63%); translocations were encountered in 15 of these patients (19%). The chromosome most often participating in translocations was number 19. Modal number was found to be an independent prognostic factor. Modal numbers 47-50 were associated with the poorest prognosis. The hyperdiploid clone with more than 50 chromosomes and the normal karyotype had the best prognosis.
