来自美国临床肿瘤学会2015年年会的报道:
Background: MZL are uncommon B-cell lymphomas. The outcomes and prognostic factors of MZL remain poorly defined. 背景:边缘区淋巴瘤是比较少见的B细胞淋巴瘤。边缘区淋巴瘤的转归和预后因子尚不明确。
Methods: We retrospectively identified 485 cases ofMZL diagnosed between 1994-2014 from 2 institutions. Diagnoses had been confirmed by expert hematopathologists. We excluded 127 cases because of limited data and overlapping features with other lymphoma subtypes. 方法:我们回顾性的确定了485例在1994年-2014年期间确诊于两家机构的边缘区淋巴瘤。病理经血液学病理专家确认。其中有127例因为数据不全和与其它类型淋巴瘤在特点上有重合而被我们排除。
Results: Of the 358 patients (pts) included in the analysis, 216 (60%) had extranodal MZL (EMZL) with most EMZL arising from stomach (32%), 56 (16%) nodal MZL (NMZL), 64 (18%) splenic MZL (SMZL), and 22(6%) had typical MZL phenotype but were unclassifiable. Median age was 66(range 13-95) years, 171 (48%) pts had stage III/IV disease at diagnosis.B-symptoms were present in 33 (9%) pts and 65 (18%) had > 4 nodal sites (LN)involved. Median time from diagnosis to treatment was 33 (2-1883) days and median duration of follow-up was 40.3 (2.2-236.4) months. 结果:在我们分析的358例病人中,216例(60%)是结外边缘区淋巴瘤,主要是胃MALT(32%),56例(16%)是结内边缘区淋巴瘤,64例(18%)是脾边缘区淋巴瘤,还有22(6%)例是具有边缘区免疫表型但不能分类的淋巴瘤。中位年龄是66岁(13岁-95岁),171例(48%)确诊时具有III/IV期疾病。另外,33例(9%)有B症状,65例(18%)有超过4个淋巴结区侵犯。从确诊到开始治疗的中位时间是33天(2-1883天),中位随访时间是40.3个月(2.2-236.4个月)。
Among treated pts, initial treatment was rituximab (R) (33%), chemotherapy +/- R (22%), radiation (16%),surgery (16%), and antibiotics (13%). Progression-free survival (PFS) and overall survival (OS) for the whole group was 5.15 (95% confidence intervals;C.I. = 2.8-10) and 19 (95% C.I. = 10-19) years respectively and there was nosignificant difference in PFS or OS between EMZL, NMZL, SMZL, or atypical MZL. 在治疗的病人中,初治有33%是美罗华单药,22%是化疗+/—美罗华,16%是放疗,16%是手术,13%是抗生素。整个组的无进展生存期和总生存期分别为5.15年和19年,几种亚型之间生存率没有明显区别。
On univariate analysis, age >60 (p = 0.002), elevated serum lactate dehydrogenase (LDH) (p = 0.003),involvement of > 4 LN (p = 0.019), follicular lymphoma International Prognostic Index (FLIPI) score (p = 0.0005), and hemoglobin (Hb) level < 12g/dL at presentation (p = 0.003) were associated with inferior OS. In amultivariate analysis, only age (hazard ratio (HR) = 5.48, p = 0.002) and Hb(HR = 2.97, p = 0.009) retained significance. Transformation to aggressive lymphoma occurred in 29 (8%) pts and was associated with high serum LDH andhigher FLIPI at diagnosis. In pts treated with R +/- chemotherapy, Rmaintenance was associated with improved OS (p = 0.04). 通过单变量分析,确诊时年龄>60,LDH升高,超过4个淋巴结区域侵犯,较高滤泡性淋巴瘤国际预后指数,和血红蛋白<12g/dL与不良预后相关。29例(8%)发生了向侵袭性淋巴瘤的转化,与确诊时LDH升高和较高国际预后指数相关。对于经R+/-化疗治疗的病人,美罗华维持与总生存期改善有关。
Conclusions: In our MZL series, one of the largest reported, prognosis of MZL is good with a median OS of over 19 years. Age >60, Hb < 12 g/dL, elevated LDH, and > 4 LN involved are associated with inferior OS. 结论:我们对边缘区淋巴瘤的研究是已报道的研究中规模最大的之一,结论是边缘区淋巴瘤总体预后良好,中位总生存期超过19年。年龄>60,血红蛋白<12g/dL,LDH升高,超过4个淋巴结区域侵犯与不良预后相关。
