摘 要:目的:分析我中心2007年至2013年确诊的34例Burkitt淋巴瘤(BL)的病理、临床特征及12例临床特点和预后关系。方法:回顾分析2007年-2013年我中心确诊的34例BL(占淋巴瘤总数1.43%,B细胞淋巴瘤2.03%)的病理资料及12例接受治疗的患者临床资料,治疗方法为[hyper CVAD(A+B)±R(利妥昔单抗)]±自体造血干细胞移植(allo-HSCT),观察短期疗效[完全缓解(CR)和部分缓解(PR)]和长期疗效[包括1年和2年总生存率(OS)及无进展生存率(PFS)],分析预后影响因素。结果:34例患者中男∶女=10∶7,中位年龄23.5岁(3-74岁),0-14岁29.4%(10/34),15-22岁23.5%(8/34),大于22岁47.1%(16/34)。全身各脏器均可发病,主要以浅表淋巴结、脑部及鼻咽部为主。Ki-67指数均大于95%以上;c-myc阳性77%(10/13)。其中12例在我中心接受治疗,Ⅱ期1例(8.4%),Ⅲ-Ⅳ期11例(91.7%)。诱导治疗:11例(91.7%)采用hyper CVAD(A+B)方案化疗,3疗程后2例达PR,9例(82%)达CR。9例达CR的患者中有1例采用CHOPE方案巩固化疗,1年内复发;5例采用hyper CVAD(A+B)巩固化疗6疗程,1例1年后复发,2年OS及PFS分别为100%、80%。3例采用hyper CVAD(A+B)+利妥昔单抗(R)方案巩固化疗6疗程,2年OS及PFS均为100%,PFS较未用R组高。3例在巩固、维持治疗后序贯allo-HSCT,随访至2年无复发,病情稳定,OS及PFS均为100%。随访2年无复发8例,年龄小于15岁占50%(4/8),15-22岁占37.5%(3/8),大于22岁占12.5%(1/8)。结论:BL主要发生在儿童和青少年,男性高于女性,可累及全身各个器官,诊断时临床分期常较高,需要高强度、高频率、足疗程、规律化疗,尤其是儿童及青少年患者。利妥昔单抗和大剂量化疗药物协同使用,序贯自体造血干细胞移植巩固治疗能提高OS率与PFS,但仍需要临床大样本研究。Objective: To analyze the pathology,clinical features of 34 cases of Burkitt lymphoma( BL),confirmed in our center from 2007 to 2013,and the relationship between the treatment and curative effect in 12 cases. Methods:To retrospectively analyze the pathological data of 34 cases of BL diagnosed in our center 2007- 2013( accounting for1. 43% of the total number of lymphoma in our hospital,accounting for 2. 03% of B cell lymphoma) and the clinical data of 12 patients treated in our center. Chemotherapy [hyper CVAD( A + B) ± R( rituximab) ]± autologous hematopoietic stem cell transplantation,observe the short- term remission rate[comoplete remission( CR) and partial remission( PR) ] and the long- term efficacy including 1 year and 2 years overall survival rate( OS),progression free survival( PFS). Results: Male∶ Female = 10∶ 7 of 34 diagnosed patients,the median age was 23. 5 years( 3 - 74 years),0 - 14 29. 4%( 10 /34),15 - 22 23. 5%( 8 /34),more than 22 47. 1%( 16 /34). It involves in various organs of the body( mainly in lymph nodes,brain and nasopharynx); Ki- 67 index were greater than 95%. Among them,12 cases treated in our center,1 case( 8. 4%) in phase II,4 cases( 33. 3%) in stage III,seven cases( 58. 3%) in stage IV.Receiving treatment in 12 patients,1 case with bone marrow infiltration,after 1 course treatment of the VDCP chemotherapy,disease progression,death. 11 cases( 91. 7%) were take 3 course of the treatment of hyper CVAD( A + B)chemotherapy,2 cases partial remission( PR),9 cases complete remission( CR),the complete remission rate was82%. In 9 cases of CR patients,1 case treated with CHOPE regimen chemotherapy,recurrence within 1 year,5 cases take hyper CVAD( A + B) to consolidate the 6 course of chemotherapy,1 case of recurrence after 1 year,the 2 year overall survival rate( OS) and progression free survival( PFS) were 100% and 80%. 3 cases were taked hyper CVAD( A + B) + R regimen to co
