p15、DAPK、SOCS1和FHIT 4基因甲基化聯(lián)合檢測在骨髓增生異常綜合征早期診斷及預后評估中的價值
[Abstract]:Objective: to investigate the value of combined detection of methylation of p15 DAPKG SOCS1 and FHIT 4 gene in the early diagnosis and prognosis of myelodysplastic syndrome (MDS). Methods: methylation specific PCR (MSP) was used to detect the methylation of bone marrow of 67 patients with MDS, and the value of combined detection of four genes in early diagnosis and prognosis evaluation of MDS patients was analyzed. Results: the methylation rates of p15DAPKG SOCS1 and FHIT in 67 patients with MDS were 37.335.8% and 52.2%, respectively, which were significantly higher than those in the control group (P0.05). The positive coincidence rates of the four genes in the diagnosis of MDS were 37.335.8% and 52.2%, respectively, and the positive coincidence rates of the four genes combined in the diagnosis of MDS were 37.3% and 52.2%, respectively. The positive coexpression rate of more than 2 genes in relative high risk group was significantly higher than that in relatively low risk group (P0.05). The median survival time of). MDS patients was 18 months (13.322.7 months). The median survival time of the patients in the relatively low risk group was significantly longer than that in the relatively high risk group [27 (20.3 / 33.7) vs 9 (5.9 / 12.1) months] (P0.05). In patients with different risk, with the increase of the number of expressed genes, the survival time of patients was significantly shortened (P0.05). Conclusion: the combined detection of p15 DAPKG SOCS1 and FHIT genes is helpful to improve the early diagnosis and prognosis of MDS patients.
