【摘要】:目的:研究多參數(shù)流式細(xì)胞術(shù)檢測白血病細(xì)胞微小殘留病(MRD)在成人B系急性淋巴細(xì)胞白血病(B-ALL)中的臨床價值,討論其在判斷疾病復(fù)發(fā)、預(yù)后及指導(dǎo)個體化治療等方面的作用。方法:回顧性研究于2008年6月1日至2011年6月30日期間,在蘇州大學(xué)附屬第一醫(yī)院診斷和治療的100例成人B系急性淋巴細(xì)胞白血病患者,在患者誘導(dǎo)和鞏固治療階段,采用多參數(shù)流式細(xì)術(shù)動態(tài)監(jiān)測患者體內(nèi)白血病細(xì)胞微小殘留病。結(jié)果:1.在誘導(dǎo)治療14天,低風(fēng)險組(MRD10-3)23例,平均無復(fù)發(fā)生存時間27.22±17.896個月,其中:RFS12個月3例(13%),RFS≥12個月20例(87.0%);高風(fēng)險組(MRD10-3)38例,平均無復(fù)發(fā)生存時間11.82±11.239個月,其中:RFS12個月23例(60.5%),RFS≥12個月15例(39.5%);P=0.000。2.在誘導(dǎo)治療28天,低風(fēng)險組(MRD10-3)46例,平均無復(fù)發(fā)生存時間21.13±17.080個月,其中:RFS12個月15例(32.6%),RFS≥12個月31例(67.4%);高風(fēng)險組(MRD10-3)18例,平均無復(fù)發(fā)生存時間9.28±8.094個月,其中:RFS12個月12例(66.7%),RFS12個月6例(33.3%);P=0.023。3.在治療后16周,低風(fēng)險組(MRD10-3)41例,平均無復(fù)發(fā)生存時間23.39±15.862個月,其中:RFS12個月8例(19.5%),RFS≥12個月33例(80.5%);高風(fēng)險組(MRD10-3)17例,平均無復(fù)發(fā)生存時間5.59±2.980個月,其中:RFS12個月15例(88.2%),RFS≥12個月2例(11.8%);P=0.000。4.在治療后28周,低風(fēng)險組(MRD10-3)35例,平均無復(fù)發(fā)生存時間24.63±16.707個月,其中:RFS12個月8例(22.9%),RFS12個月27例(77.1%);高風(fēng)險組(MRD10-3)14例,平均無復(fù)發(fā)生存時間8.43±3.228個月,其中RFS12個月9例(64.3%),RFS≥12個月5例(35.7%);P=0.009。結(jié)論:在成人B系急性淋巴細(xì)胞白血病誘導(dǎo)治療及鞏固治療階段,MRD偏高或持續(xù)升高,提示疾病復(fù)發(fā)風(fēng)險增加,無復(fù)發(fā)生存時間明顯縮短。因此,MRD的檢測可以預(yù)測成人B-ALL的復(fù)發(fā)、判斷預(yù)后和指導(dǎo)個體化治療。
[Abstract]:Objective: to study the clinical value of multi-parameter flow cytometry in detecting minimal residual disease (MRD) of leukemia cells in adult B acute lymphocytic leukemia (B-ALL), and to discuss its role in judging disease recurrence, prognosis and guiding individualized treatment. Methods: from June 1, 2008 to June 30, 2011, 100 adult patients with acute lymphoid leukemia B were diagnosed and treated in the first affiliated Hospital of Suzhou University. Multi-parameter flow cytometry was used to dynamically monitor the minimal residual disease of leukemia cells in patients during induction and consolidation treatment. Result: 1. After 14 days of induction therapy, 23 cases in the low risk group (MRD10-3) had an average non-recurrence survival time of 27.22 鹵17.896 months, including 3 cases of RFS12 months (13%), RFS 鈮,
