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.     

增生性瘢痕组织中肿瘤坏死因子α R1 mRNA的表达及意义

目的：从基因水平探讨肿瘤坏死因子受体(TNF-α R1)在增生性瘢痕组织发生、发展过程中的作用，为增生性瘢痕的基因治疗探索一条有效途径。方法：以正常瘢痕为对照，利用RT-PCR技术检测1年以上增生性瘢痕组织成纤维细胞中TNF-α R1 mRNA的表达情况。结果：1年以上增生性瘢痕组织中TNF-α R1 mRNA的表达稳定，与正常瘢痕比较含量明显下降。结论：增生性瘢痕的形成与TNF-α R1的表达低下有一定关系。用基因治疗的方法提高早期增生性瘢痕中TNF-α的含量或者提高靶细胞膜上TNF-α R1的数目与活性可能为增生性瘢痕的康复治疗的有效途径。

DVd(T)方案治疗多发性骨髓瘤17例临床疗效分析

目的:观察脂质体阿霉素(PLD)联合长春新碱(VCR)、地塞米松(Dex)士沙利度胺(Thal)治疗多发性骨髓瘤(MM)患者的疗效及毒副反应.方法:17例初治或复发难治MM患者接受DVd(PLD 40 mg·m-2d1、VCR 2 mg d1、Dex 40 mg d1～4)或DVdT(PLD及VCR用法用量同上,Dex:40 mg,d1～4、d9～12;Thal:100 mg,d1～21)治疗,按照EBMT标准评价疗效、WHO标准判断毒副反应.结果:①17例患者共完成了34个周期的治疗,总有效率(ORR=CR+nCR+VGPR+PR)为58.8%,与国外文献报道接近,与历史上我院采用的VAD及其类似方案相比疗效也接近.②采用DVd方案治疗的11例患者的ORR为4/11(36.4%).其中6例初治患者的ORR为2/6(33.3%).采用DVdT方案化疗的6例患者均为初治病例,其ORR为6/6(100%).对于初治患者.DVdT方案的ORR显著好于DVd方案.③多数治疗相关毒副反应为1～2级且可耐受.17例患者中有13例在接受DVd(T)化疗前心电图或心脏B超示不同程度的心律失常或左室舒张功能降低,但均未因化疗增加心脏毒性.DVd组与DVdT组的毒副反应接近.结论:DVd方案具有较好的耐受性,适当延长Dex用量并加入Thal可以在不增加化疗相关毒性的同时显著提高DVd方案疗效.     

造血干细胞移植治疗16例多发性骨髓瘤疗效分析

目的：评价造血干细胞移植（SCT）治疗多发性骨髓瘤（MM）患者的疗效。方法：回顾性分析我院SCT治疗16例D-S分期Ⅲ期MM患者。自体造血干细胞移植（ASCT）13例。2例原发耐药、2例ASCT后复发和1例高危患者接受HLA匹配同胞供者异基因造血干细胞移植（allo-SCT）;其中4例应用清髓性预处理。采用NCI/SWOG（2004年前）和EBMT标准分析治疗反应。结果：共完成ASCT20例次,无移植相关死亡（TRM）。ASCT后均有效,9例获得完全缓解（CR）,4例部分缓解（PR）。10例移植前CR/PR者,中位随访35（6～126）个月,3例复发/进展,中位总生存（OS）尚未达到[已超过35（6～119）个月],中位无进展生存（PFS）27（1～50）个月。3例ASCT前处于疾病稳定状态（SD）者分别于移植后11、7和5个月后复发/进展。Allo-SCT组1例预处理后早期TRM,余3例CR,1例PR。1例患者移植后4个月死于急性移植物抗宿主病（GVHD）合并严重肺感染;余3例生存分别已达39、41和14个月,其中仅后者仍持续PFS。结论：ASCT治疗MM耐受性好,能明显延长PFS和OS;原发难治患者ASCT仍有效,但PFS持续时间短暂。沙利度胺联合治疗用于移植前/后可能提高疗效。allo-SCT有效提高高危及复发/难治患者的治疗反应率。     

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.     

206例多发性骨髓瘤患者不同方案疗效分析

目的　探讨不同化疗方案对多发性骨髓瘤(MM)患者的治疗效果。方法　回顾性分析了206例MM患者的治疗情况,对不同治疗方案的疗效进行比较。结果　200例药物治疗患者的中位生存期为30. 5个月, 3年和5年实际生存率分别为32. 01%和15. 8%。195例行常规化疗患者的总有效率为45. 6%,其中完全缓解率14. 9% (29例),部分缓解率30. 8% ( 60例)。联合化疗组的总有效率为50. 3%,明显高于MP(马法兰和泼尼松)方案组的总有效率(30. 4% ) (P<0. 05);这两组的中位生存期分别为30. 5个月和30. 0个月、3年和5年生存率分别为35. 0%和22. 0%, 16. 7%和13. 2%,差异无统计学意义(P值均>0. 05)。合并干扰素治疗组的有效率为53. 6% ,中位生存期52. 0个月,与未用干扰素治疗组(分别为34. 4%, 27. 0个月)相比,有效率提高(P<0. 05)、生存期延长(P<0. 01)。合并沙利度胺治疗的总有效率为65. 5%。6例外周血造血干细胞移植患者有5例存活,平均生存期为(73. 0±12. 5)个月。结论　联合化疗的有效率高于MP方案,但两组的总生存率差异无统计学意义。干扰素能使化疗有效率增加,中位生存期延长。沙利度胺也能够提高MM患者的治疗有效率。对于年龄较轻、一般状态较好的患者,自体干细胞移植可明显提高生存期。     

43例淋巴母细胞淋巴瘤患者临床特点及疗效分析

Objective To investigate the clinical features and treatment outcomes of different regimens in Chinese patients with lymphoblastic lymphoma(LBL). Methods Forty-three patients with LBL were retrospectively analysed, of which 30 were T-LBL, and 13 B-LBL. Results ①Most patients were young men with a median age of 21, and 63.0％ of the T-LBL patients had mediastinal masses. ② Treatment outcome could be assessed in 37 cases, of which the response rate (RR) was 81.1％ and complete remission (CR) rate was 67.6％. The RR and CR rates in patients treated with regimens for ALL (ALL-like group) and those treated with regimens for NHL(NHL-like group) were 94.4％ , 68.4％ and 83.3％ , 52.6％ , respectively. ③The estimated median overal survival(OS) and progression free survival (PFS) of hematopoietic stem cell transplantation (HSCT) group were significant longer than those of ALL-like group(P =0.018, P=0.025) and NHL-like group(P = 0. 016, P = 0. 011). The OS at 5 years in NHL-like group, ALL-like group and HSCT group were (14.4 ± 9.4) ％ , (20.2 ± 12.7) ％ and (79.5 ± 13.1) ％, respectively. Conclusion ①LBL is more common in young men, with less involvement of peripheral blood. Compared with B-LBL, T-LBL often has a mediastinal mass and serious cavity effusion. ② Intensive treatment regimens for ALL should be used in LBL. HSCT at CR1 can improve outcome obviously.
