老年白血病个体化治疗探讨 总被引:1,自引:0,他引:1
59例老年白血病治疗中,联合化疗组48例中,CR占29.2%.PR占25%,总有效率54.2%;小剂量诱导组11例,PR占18.2%.总有效率18.2%。两组差异显著(P<0.05)。提示对老年患者宜采用个体化选择不同方案治疗。 相似文献

目的 对1例伴有ins(15;17),t(2;17;20),+8复杂异常的急性早幼粒细胞白血病(acute promyelocytie leukemia,APE)病例进行细胞和分子遗传学研究.方法 按常规制备染色体,以R显带技术进行核型分析,并先后作多色荧光原位杂交(multiplex fluoresence in situ hybridization,M-FISH)、染色体涂染和PML-RARa双色FISH检测.结果 R显带核型分析为47,XY,2q-,+8,17q+,20p+;M-FISH检测为:47,XY,t(2;17;20)(q24;q21;p13),+8;染色体涂染证实了2qZ4以下片段易位到17q21上和17q21以下片段易位到20p13上;双色FISH示17号染色体上RARa(retinoic acid receptora,RARe)基因部分片段插入到15号染色体形成PNL-RARa融合基因,即ins(15;17)(q22;q21.1q21.3).结论 FISH技术是明确隐匿/插入易位的可靠手段,凡形态学拟诊为APL而常规核型分析未发现t(15;17)者均应进行FISH检测. 相似文献

母供子非去T细胞性单倍体异基因造血干细胞移植治疗恶性血液病 总被引:2,自引:0,他引:2
目的:对18例恶性血液病进行母供子非去T细胞性单倍体异基因造血干细胞移植(Allo-HSCT)治疗,探讨其疗效及毒性反应。方法:6例急性髓系白血病(AML-M23例,AML-M41例,AML-M5b2例),3例慢性粒细胞白血病(伴骨髓纤维化1例),8例急性淋巴细胞白血病(ALL),非霍奇金淋巴瘤(Ⅳ期B组)1例,以母亲为供者进行非去T细胞性单倍体Allo-HSCT。供者动员方案:G-CSF300μg/12h×5d后采集造血干细胞。输注D34 细胞(3.58~8.90)×106/kg。预处理方案为:MeCCNC250mg·m-2·d-1×1d,Ara-C4g·m-2·d-1×2d,Bu4mg·kg-1·d-1×3d,CTX1.8g·m-2·d-1×2d。ALL患者以全身放疗(TBI)代替Bu。以CsA、MMF、MTX和ALG预防移植物抗宿主病(GVHD)。结果:所有患者均顺利完成预处理。移植后发生急性GVHD16例、慢性GVHD10例,出血性膀胱炎1例。全部患者在移植后10~20d获造血重建。18例患者中12例存活。结论:非去T细胞性单倍体Allo-HSCT是治疗恶性血液病的一种安全、有效的方法;同时提示在以后的单倍体异基因造血干细胞移植中优先选择母亲供体,对降低GVHD的严重程度、提高移植成功率是有帮助的。 相似文献

Objective To establish and characterize a novel human myeloid leukemia cell line SH-2. Methods Bone marrow mononuclear cells(BMMNC) isolated from a AML-M2 patient, who failed to ob-tain complete remission after chemotherapy and allogenic bone marrow transplantation were passed in a long term IMDM culture medium supplemented with 20% fetal calf serum. Stromal cells were retained and rh-IL-3was added in the culture system. A new human myeloid leukemia cell line SH-2 was successfully established with a cytogeuetic characteristics of a loss of Y chromosome(- Y), a derivative chromosome 16 resulting from unbalanced translocation between chromosome 16 and 17, monosome 17, trisomy 19 and p53 alteration. Vari-ous methods were employed to characterize SH-2 cell line. Results SH-2 cells has been maintained without cytokine and stromal cells for more than 3 years without EB virus and mycoplasma contamination. SH-2 cells had the basically same morphological, immunophenotypic and cytogenetic features as the patient' s leukemia cells did, such as myeloid morphology, an immunophenotype of CD13+ , CD33+ , CD56+ , CD16/56+ and a hypodiploid karyotype of 45, X, - Y, der(16) t(16;17) (q24;q12) , - 17, + 19, which were gradually de-creased and replaced by the near-tetraploid cells with a karyotype of 73 - 102 (80), XX, - Y, - Y, del (lq31) ×2, der(16)t(16;17) (q24;q12) ×2, - 17, - 17, + 19, + 19. FISH and multiple FISH delineated all the abnormalities and revealed a loss of one p53 allele due to monosomy 17. DNA direct sequencing detec-ted a point mutation of CAG to CAT at codon 576 of exon 5 in another p53 allele. RT-PCR showed that SH-2 cells expressed apoptosis-related genes (bcl-2, Fas, GST- π and p21) rather than MDR-related genes. Short tandem repeat PCR provided powerful evidence for the derivation of SH-2 cell line from the patient' s leukemia cells. SH-2 cells had certain colony formation and tumorigenic capacities in nude and SCID mice. Conclu-sion SH-2 is a new myeloid leukemia cell line with a unique biology background, and will provide a useful tool for leukemia research. 相似文献
