混合表型急性白血病32例临床研究

目的 分析混合表型急性白血病(MPAL)的临床、生物学特征和预后.方法 总结2003年1月至2009年6月收治的32例MPAL患者资料,分析其骨髓细胞形态学、细胞免疫表型、细胞遗传学和分子生物学特点.32例患者采用了兼顾髓系、淋系的联合化疗方案治疗,2例在缓解期进行了异基因造血干细胞移植(allo-HSCT).对患者进行疗效和生存分析.结果 ①MPAL在急性白血病中的发生率为2.6%,32例MPAL患者中髓系和B系(M/B)表型16例(50.0%),髓系和T系(M/T)表型14例(43.8%),髓系、B、T三系(M/B/T)表型和B/T系表型各1例(3.1%).②CD34和HLA-DR阳性率分别为87.5%和62.5%.③异常核型发生率为70.0%(30例中21例),涉及Ph、11q23和复杂核型在内的结构重排和(或)数目异常.④32例MPAL患者总完全缓解(CR)率75.0%,2年总生存(OS)率和无病生存(DFS)率分别为14.8%和14.2%.M/B和M/T表型CR率分别为75.0%和71.4%.M/B和M/T表型患者的OS和DFS率比较差异无统计学意义.2例allo-HSCT患者均未复发,生存期延长.结论 MPAL是一类异质性的急性白血病亚型,其不良预后可能与染色体异常发生率高、CD34高表达和易于髓外浸润等因素有关.兼顾髓系、淋系的联合化疗和包括HSCT的强烈治疗可能有助于提高疗效.

Abstract：

Objective To investigate the clinical and biological characteristics and prognosis of mixed phenotype acute leukemia (MPAL). Methods Thirty two patients were diagnosed as MPAL by bone marrow examination, immunophenotyping, cytogenetic and molecular assay and were treated with combined chemotherapy regimens for both acute lymphoblastic and acute myeloid leukemia. Two cases were received allogeneic hematopoietic stem cell transplantation (allo-HSCT). Results ① The incidence of MPAL in acute leukemias was 2. 6%. There were 16 cases ( 50. 0% ) of mixed myeloid and B-lymphoid ( M/B), 14(43.8%) myeloid and T-lympboid ( M/T), one each (3.1%) of trilineage (M/B/T) and B- and T-lymphoid (B/T) phenotype. ② The positive rates of CD34 and HLA-DR were 87.5% and 62.5%, respectively.③Abnormal karyotypes were detected in 70.0% of 30 MPAL patients, which were structural and numerical abnormalities including t(9;22), 11q23 and complex karyotypes. ④ The total complete remission (CR) rate was 75.0% and the overall survival (OS) and disease-free survival (DES) at 2 years were 14. 8% and 14.2% respectively. The CR rates for M/B and M/T cases were 75.0% and 71.4% respectively. No statistical difference was observed in OS and DFS between M/B and M/T cases. Conclusions MPAL is a rare type of acute leukemia with a high heterogeneity. The unfavorable indicators of MPAL may be factors such as abnormal karyotypes, high expression of CD34 and extramedullary infiltration. Combined regimens and more intensive therapy including allo-HSCT might contribute to improving survival.

目的 探讨DNA同源重组修复基因RAD51-G135C和XRCC3-C241T多态性与inv(16)/t(16;16)/CBβ-MYH11阳性急性髓系白血病(AML)患者预后之间的关系.方法 对染色体核型可供分析且随访资料完整的103例初治原发性inv(16)/t(16;16)/CBβ-MYH11阳性AML患者进行回顾性分析.用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法检测患者RAD51-G135C、XRCC3-C241T基因多态性.采用单因素(包括性别、初诊时年龄、白细胞计数、血小板计数、血红蛋白含量、染色体核型、KIT基因突变、RAD51-G135C和XRCC3-C241T基因多态性)和多因素分析方法评估患者完全缓解(CR)率、总体生存(OS)率和无复发生存(RFS)率的影响因素.结果 全部患者中位随访时间为28(1-106)个月,总体CR率为92.2%,预期5年OS率和RFS率分别为43.6%(95%CI 37.7%-49.5%)和26.4%(95%CI 21.1%-31.7%),预期中位OS时间和RFS时间分别为53.0(95%CI 33.4～72.7)个月和27(95%CI 22.9-31.1)个月.多因素分析结果显示:高白细胞计数(P=0.004)和年龄＞30岁(P=0.035)是与CR率有关的独立不良预后因素,XRCC3-C241T变异基因型(P=0.007)和高白细胞计数(P=0.009)是与RFS率有关的独立不良预后因素,高白细胞计数(P=0.002)和伴有+8染色体核型异常(P=0.035)是与OS率有关的独立不良预后因素;而RAD51-G135C基因型对此类白血病的预后无明显影响.结论 XRCC3-C241T变异基因型是inv(16)/t(16;16)/CBFβ-MYH11阳性AML一个独立的不良预后因素.

Abstract：

Objective To investigate the impact of polymorphisms of DNA homologous recombination (HR) repair genes RAD51-G135C and XRCC3-C241T on the prognosis of acute myeloid leukemia(AML)with inv(16)/t(16;16)(CBFβ-MYH11).Methods One hundred and three de novo inv( 16)/t(16;16)(CBFβ-MYH11) AML patients were followed-up and retrospectively analyzed.Polymorphisms of RAD51-G135C and XRCC3-C241T were detected by PCR-RFLP.The prognostic factors,including sex, age, white blood cell count, platelet count, hemoglobin level, karyotype, KIT mutation, RAD51-G135C and XRCC3-C241T polymorphisms at diagnosis, for complete remission (CR) achievement, overall survival (OS) and relapse-free survival (RIPS) were analyzed by univariate and multivariate analyses.Results The median follow-up of all patients was 28 (1 - 106) months.The overall CR rate was 92.2%.The estimated 5-year OS and RFS rates were 43.6% (95 % CI 37.7 % - 49.5 % ) and 26.4% (95% CI 21.1% - 31.7% ), and the median OS and RFS were 53 (95%CI33.4 -72.7) and 27 (95%CI22.9 -31.1) months, respectively.In multivariate analysis, higher WBC ( P = 0.004) and older than 30 years of age ( P = 0.035 ) were independent poor factors for CR achievement, the XRCC3-241T variant (P =0.007) and higher WBC (P =0.009)were independent poor factors for 5-year RFS,and higher WBC(P=0.002)and trisomy 8(P=0.035)were independent poor factors for 5-year survival.Polymorphism of RAD5 1-G135C had no significant impact on the prognosis.Conclusion The XRCC3-241T variant is an independent poor prognostic factor for AML with inv(16)/t(16;16)/CBFβ-MYH11.     

203例慢性淋巴细胞白血病患者预后相关因素分析

Objective To explore prognostic factors in patients with chronic lymphocytic leukemia (CLL). Methods Two hundred and three CLL patients in our hospital between 2000 to 2007 were retro-spectively reviewed for prognostic factor analysis. Survival was analysed by Kaplan-Meier analysis, univariate analysis by Log-rank test and multivariate analysis by COX regression model. Results With a median follow-up time of 48.0 (3.0 - 156.0) months, the 5-year overall survival (OS) rate was (87.3 ± 2.4) % and 10-year OS rate was (77.4 ± 3.3) %. Forty-eight (23.6%) patients died. Univariate analysis indicated that ad-vanced clinical stage, B symptoms, extranodal involvement, number of lymph node regions involved ≥3, en-larged liver, Hb < 100 g/L, BPC < 100 × 109/L, absolute lymphocyte count (ALC) > 50 × 109/L, atypical cell morphology, progression to stage, non-respons to treatment, complicating infections and secondary cancer or disease transformation were associated with poor prognosis. And on multivariate analysis, lymph node re-gion involvod≥3 and atypical cell morphology were independent poor prognostic factors. Based on the two in-dependent poor prognostic factors, three risk groups were defined: low- (0 factor), intermediate-(one factor) and high-(two factors) groups. The 5 year OS rates were (89.8 ± 3.5) % , (66.4 ～ 7.2) % and (15.0 ±13.8)%, respectively, and the difference between them was statistically. Conclusion The number of lymph node region involved and cell morphology are useful for assessing CLL patients prognosis.

HA为基础的三药方案治疗急性髓系白血病疗效分析及与染色体核型的关系

目的对12年来用HA（高三尖杉酯碱、阿糖胞苷）为基础的三药联合方案诱导化疗的243例急性髓系白血病（AML）患者的完全缓解（CR）率、无病生存（DFS）以及总生存（OS）情况进行总结分析,同时探讨不同染色体核型分组对治疗缓解率及预后的影响.方法用HA为基础的三药联合方案诱导治疗初治、原发AML 243例,计算CR率、DFS期、OS期及3年和5年DFS率、OS率.对其中有染色体核型结果的184例患者根据SWOG或MRC核型分级标准进行分组,比较不同核型组之间CR率、DFS期（率）及OS期（率）.采用SPSS软件分析所得数据.结果243例原发、初治AML患者CR率达77.4%,188例CR患者中位DFS期为28.5（1.0～153.0）个月,3年DFS率为45.4%,5年DFS率为40.2%.243例患者中位OS期为18.4（0.5～154.0）个月,3年OS率为36.9%,5年OS率为31.4%.按SWOG标准将184例患者根据染色体核型分析结果分为良好、中等、差、未知四组,四组的CR率、中位DFS期及OS期分别为良好核型组97.8%、87.4个月、89.1个月,中等核型组81.9%、17.6个月、22.3个月,差核型组61.5%、9.0个月、11.5个月,未知核型组79.3%、29.0个月、19.9个月.以上各组之间的差异均具有统计学意义（P＜0.01）.按MRC标准将184例患者分为良好、中、差三组,三组的CR率、中位DFS期及OS期分别为良好核型组96.1%、79.9个月、72.2个月,中等核型组79.5%、17.6个月、19.7个月,差核型组43.8%、16.5个月、12.0个月.中等核型组与差核型组的DFS期差异无统计学意义（P＞0.05）,其余指标各组之间有统计学意义（P＜0.01）.结论采用HA为基础的三药联合方案诱导治疗AML,CR率较二药方案高,有利于患者的长期生存.染色体核型同样是本组患者重要的预后相关因素,SWOG染色体核型分组标准更适合患者的疗效和预后分析,而且可将未知组与预后中等组合并分析.三组不同核型患者的预后差异具有统计学意义,良好核型组的预后明显比其他两组好,中等核型组比差核型组好.     

R-CHOP方案治疗弥漫大B细胞淋巴瘤的预后因素分析

目的 重新评估R-CHOP(利妥昔单抗、环磷酰胺、阿霉素、长春新碱、泼尼松)方案治疗弥漫大B细胞淋巴瘤(DLBCL)的预后因素.方法 2000年2月至2006年9月125例初治DLBCL患嗜接受6个疗程的R-CHOP[利妥昔单抗375 mg/m2,缓慢静脉滴注,第1 d;环磷酰胺750 mg/m2,静脉推注,第2 d,阿霉素50 mg/m2,静脉推注,第2 d;长春新碱1.4 mg/m2(最大剂量2.0 mg),静脉推注,第2 d,泼尼松60 mg,口服,第2～6 d]治疗后,对患者进行治疗反应的评估和随访.结果 在入选的125例患者中,86例(68.8%)获得完全缓解(CR),16例(12.8%)获得部分缓解(PR),总反应率为81.6%,11例患者(8.8%)获得疾病稳定(SD),12例患者(9.6%)疾病进展.在单因素分析中,ECOG分级、临床分期、LDH水平、结外病变、国际预后指数(IPI)积分和巨块病变的有无均与CR有关;在多因素分析中,仅ECOG评分、临床分期和巨块病变对获得CR的差异有统计学意义(P值分别为0.0098、0.0000和0.0040).患者24个月的治疗至失败时间(TTF)、总生存(OS)率和无病生存(DFS)率分别为(59.7±5.3)%、(67.1±5.6)%和(77.6±5.8)%.在单因素分析中,年龄和结外病变对TTF、OS和DFS率均无显著影响.而其余IPI因素,包括LDH、临床分期和行为状态对OS率和TTF均有显著影响,而对DFS率无明显影响.在多因素分析中,是否获得CR是影响TTF唯一的预后因素(P=0.001),它同时影响OS率(P=0.001).其他影响OS率的指标包括LDH水平和ECOG评分(P值分别为0.002和0.009).巨块病变是影响DFS率的唯一重要因素(P=0.007).结论 R-CHOP方案治疗中,IPI预后积分的预后意义具有一定局限性.6个疗程治疗后获得CR和巨块病变可能是IPI外另两个非常重要的临床预后因素.

目的评价初治儿童急性髓系白血病(AML)的疗效及探讨除急性早幼粒细胞白血病(APL)外的 AML 的预后相关因素。方法 141例18岁以下 AML 患者分成 APL 组(A 组,51例)和除APL 外的 AML 组(B 组,90例)进行回顾性研究分析。采用 Kaplan-Meier 曲线评估患者的无事件生存(EFS)率、无病生存(DFS)率和总生存(OS)率,Cox 回归模型评估预后因素。结果 B 组1个疗程完全缓解(CR)率为54.4%(49例),总缓解率为76.7%。5年累积 EFS 率、DFS 率和 OS 率分别为(28.4±9.0)%、(28.39±8.96)%和(35.5±6.3)%;A 组5年累积 EFS 率、DFS 率和 OS 率分别为(81.5±5.7)%、(94.3±4.0)%和(81.4±5.7)%:全部141例 AML 患儿5年累积 DFS 率和5年累积OS 率分别为(56.9±6.3)%和(53.3±4.8)%。B 组病例经多因素分析表明,初诊时骨髓白血病细胞比例较高和≥2个疗程达 CR 以及巩固治疗6个疗程以下是影响患者预后的危险因素(P 值均<0.05)。结论儿童 APL 预后良好。其他儿童 AML 中,初诊时骨髓原始细胞比例低和1个疗程达CR 以及巩固治疗6个疗程以上者预后较优;儿童 M_(2h)/t(8;21)与除 APL 以外的其他亚型相比没有显示预后良好的趋势;降低复发是改善儿童 AML 预后的关键。     

CAG及CAG联合地西他滨化疗方案治疗老年急性髓系白血病的疗效比较

目的 比较CAG及CAG联合地西他滨（DAC）化疗方案治疗老年急性髓系白血病(AML)的疗效。方法 回顾性分析我院诊治的老年AML患者76例,对采用CAG或CAG+DAC两种不同化疗方案做为诱导缓解方案的患者的临床疗效进行分析,分析两组在完全缓解率,总有效率,中位生存期,中位无复发生存期的差异。结果 在老年AML患者,CAG组49例,完全缓解率为51.0%,总有效率为61.2%, CAG+DAC组27例,分别为59.3%和77.8%,两者完全缓解率和总有效率差异无统计学意义(P>0.05);在中位生存期（10.0个月 vs 12.0个月,P=0.225）和无复发生存期（8.0个月 vs 11.0个月,P=0.652）差异无统计学意义。但在高危组患者,CAG+DAC组完全缓解率,总有效率优于CAG组,分别为57.1% vs 15%;71.4% vs 25%,差异有统计学意义(P<0.05)。中位生存期6.0个月 vs 10.0个月及无复发生存期为4.0个月 vs 7.0个月(P>0.05),CAG+DAC组均有延长趋势。 结论 CAG和CAG+DAC化疗方案临床疗效相当,但对预后差的老年AML患者,CAG+DAC在临床疗效方面显示出了优势。     

成人急性淋巴细胞白血病的化疗及预后因素分析

目的 分析成人急性淋巴细胞白血病(ALL)的临床特点,比较不同化疗方案组患者的疗效,探讨影响长期生存的因素.方法 回顾性分析1998年6月至2005年12月住院治疗的成人ALL患者149例.采用SPSS11.5统计软件分析有关数据.结果 ①133例患者进行了免疫表型分析,其中B细胞表型118例(88.7%),T细胞表型15例(11.3%).有染色体核型结果的患者105例,正常核型40例(38.1%),异常核型65例(61.9%).②按诱导治疗方案不同将治疗满4周的患者分为VDCP、VDLP、VDCLP三组,诱导治疗总完全缓解(CR)率为93.7%.三组患者诱导治疗1个疗程结束时CR率分别为80.8%、92.3%、81.4%,差异无统计学意义(P=0.618).包含和不包含门冬酰胺酶的诱导方案诱导治疗结束时CR率分别为95.5%和92.1%,差异无统计学意义(P=0.566).患者中位无病生存(DFS)期为12(1～74)个月,中位总生存(OS)期为17.5(1～97)个月.三组患者3年及5年DFS率分别为18.5%和14.8%、24.7%和9.9%、39.5%和39.5%,组间差异有统计学意义(P=0.0066).③通过COX回归模型分析显示患者就诊时年龄＞40岁、WBC＞40×109/L、染色体t(9;22)及巩固治疗不足4个疗程为预后不良因素.结论 成人ALL免疫表型检测以B-ALL为主,染色体核型变化较大.多数患者在接受4或5种药物联合的诱导方案治疗后可获CR;用门冬酰胺酶不影响诱导治疗CR率,但可提高患者的DFS和OS率.染色体核型异常影响患者生存情况.充分的巩固强化治疗对延长生存期必不可少.就诊时的年龄、白细胞计数、染色体核型检查结果及巩固治疗疗程数为影响生存的预后因素.     

伊马替尼联合改良的Hyper-CVAD/MA强化方案及异基因造血干细胞移植一线治疗成人Ph阳性急性淋巴细胞白血病的临床研究

目的 探讨采用伊马替尼(IM)联合化疗后第1次完全缓解期(CR1)行异基因造血干细胞移植(allo-SCT)及IM维持治疗成人Ph阳性急性淋巴细胞白血病(Ph+-ALL)的临床疗效及相关预后因素.方法 2006年3月至2010年12月在我院淋巴肿瘤中心CR1期完成allo-SCT治疗的16例成人Ph+-ALL患者纳入研究.所有患者均以IM联合标准VDCP±L(长春新碱+柔红霉素+环磷酰胺+泼尼松±左旋门冬酰胺酶)方案诱导治疗,缓解后则联合改良HyperCVAD/MA方案强化巩固治疗,并于CR1期行allo-SCT;部分患者移植后给予IM维持治疗.随访至2011年3月31日,分析患者临床基本特征、总生存(OS)率、无病生存(DFS)率、累积复发(RI)率及非复发死亡(NRM)率,并探讨与生存相关的预后因素.结果 16例患者采用IM联合化疗在移植前均维持血液学缓解,其中10例达分子生物学缓解.移植后所有患者均成功植入.中位随访27.1(7.4 ～65.8)个月,14例患者存活,其中2例患者移植后复发经IM挽救均存活,2例非复发死亡.3年预期OS及DFS率分别为(85.9±9.3)％和(83.9±10.5)％,3年RI率及NRM率分别为(16.1±10.5)％和(14.1±9.3)％.生存分析未显示影响移植疗效的预后因素.结论 IM联合化疗及Hyper-CVAD/MA强化治疗可显著提高Ph+-ALL患者的缓解率及缓解质量,使患者在CR1期行allo-SCT的可行性增高.allo-SCT前、后联合IM能减少复发,提高长期OS及DFS率,是治疗成人Ph+-ALL的有效手段.
