ABSTRACT
This study was aimed to investigate the clinical characteristics of acute myeloid leukemia (AML) with t (8;21) (q22;q22) and loss of Y chromosomes. Clinical data of 267 cases of AML were collected from January 2010 to June 2013. Among 267 AML, there were 13 cases with t (8;21) (q22;q22) and loss of Y chromosomes. The clinical data including clinical indicators, treatment protocols, curative effect and prognosis were analyzed retrospectively. The results showed that after normalized chemotherapy, there were 4 patients with complete remission at the first cycle of treatment, 4 patients with complete remission at the second cycle, 4 patients with complete remission at the third cycle, but one patient without complete remission after 4 cycles. There were 6 patients who did not relapse during consolidation and intensive therapy. Among these 6 patients, 4 cases accepted chemotherapy combined with transplantation, other 2 cases accepted chemotherapy. In the remainder 6 patients, 4 cases relapsed once, one cases relapsed twice, 1 cases relapsed for three times. Moreover, 2 cases who accepted the chemotherapy and auto-hematopoietic stem cell trans-plantation, were diagnosed as relapse, after accepted allo-hematopoietic stem cell transplantation, currently are in disease-free status. In follow-up period, the relapse-free survival (RFS) time was 4.67 ± 3.45 months in chemotherapy group, the RFS time is 34.17 ± 21.37 months in chemotherapy and transplantation group. The chemotherapy combined with transplantation extended the RFS time (P < 0.05). It is concluded that the NCCN guide indicates that AML with t (8;21) ( q22;q22) showed a good prognosis. but the clinical course of treatment confirmed that the prognosis of AML patients with t (8;21) (q22;q22) and loss Y chromosomes is poor, including uneasy remission and easy relapse, for improving the prognosis of these patients, the hematopoietic stem cell transplantation should be recommended.
