早期鼻腔NK/T细胞淋巴瘤治疗方法和预后分析

目的 探讨不同治疗方法对早期鼻腔NK/T细胞淋巴瘤预后的影响.方法 回顾分析15年问85例ⅠE、ⅡE期鼻腔NK/T淋巴瘤放疗及CHOP为主化疗的疗效.单纯化疗(单化组)20例,放疗后±化疗(放化组)17例(单纯放疗11例),化疗后放疗(化放组)48例.生存率计算采用Kaplan-Meier法,并Logrank法检验,Cox回归模型进行多因素分析.结果 全组5年生存率为40%,单化纽、放化组和化放组的分别为13%、54%和47%,放化纽和化放组均优于单化组(P=0.030和0.049).ⅠE局限组与超腔组的5年生存率分别为57%与28%(χ2=8.87,P=0.003),ⅡE期的为23%,与ⅠE超腔组相似(χ2=0.19,P=0.664).近期疗效达到完全缓解与未完全缓解的5年生存率分别为58%与12%(χ2=30.68,P=0.000).放疗剂量≤50 Gy与>50 Gy的完全缓解率分别为56%和86%(χ2=6.11,P=0.013),5年无复发生存率分别为89%与84%(χ2=0.36,P=0.551).首程化疗的68例中≤2、3～4、≥5个疗程者分别为18、20、30例,完全缓解率分别为0%、20%、33%(χ2=7.65,P=0.022).首程先化疗且≥3个疗程的50例和先放疗≥40 Gy的17例的完全缓解率分别为28%和88%(χ2=18.75,P=0.000).结节型和溃疡型的完全缓解率放疗均优于化疗(100%:38%,2X=7.92,P=0.005和100%:11%,χ2=14.40,P=0.000).多因素分析显示临床分期和近期疗效是影响预后的独立因素.结论 早期鼻腔NK/T细胞淋巴瘤首程应选择50 Gy放疗为宜.对于ⅠE期超腔与ⅡE期应酌情联合化疗,但CHOP方案效果欠佳.     

早期鼻腔NK/T细胞淋巴瘤治疗方法和预后分析

Objective To investigate the prognosis of patients with nasal NK/T cell lymphoma receiving different treatment modalities. Methods From 1990 to 2004, 85 patients with stage ⅠE and ⅡE primary nasal NK/T cell lymphomas were retrospectively studied. Twenty patients received chemotherapy of CHOP regimen alone, 11 patients received radiotherapy only, 6 patients received radiotherapy followed by more than 2 cycles of chemotherapy, and 48 patients received more than 2 cycles of chemotherapy followed by radiotherapy. Survival analysis was performed by the Kaplan-Meier method, the difference between groups was evaluated by the Log-rank test, and the Cox regression model was used for multivariate analysis. Results The 5-year overall survival rate (OS) was 40%. The 5-year OS was 57% and 28% for limited stage ⅠE and extended stage ⅠE(X2 =8. 87, P =0. 003), and 23% for stage ⅡE, which was similar to extended stage ⅠE (X2 =0. 19, P-0. 664). The 5-year OS was 13%, 54% and 47% for chemotherapy alone, radiotherapy followed with or without chemotherapy, and chemotherapy followed by radiotherapy, respectively. The last two groups had better OS than chemotherapy alone (P = 0. 030 and 0.049). The 5-year OS was 58% and 12% for patients achieving complete response (CR) and uncomplete response (X2 = 30.68, P = 0. 000).The CR rate was 56% and 86% for radiotherapy of ≤50 Gy and >50 Gy (X2 =6.11, P=0. 013). The corresponding 5-year relapse-free survival rate was 89% and 84% (X2 =0.36, P=0.551). Of 68 patients receiving initial chemotherapy, the CR rate of those who received ≤2, 3-4 and ≥5 cycles was 0, 20%and 3 3 % , respectively (X2 = 7.65 , P = 0. 022) . For 5 0 patients who received ≥ 3 cycles of initial chemotherapy and 17 patients who received initial radiotherapy of ≥40 Gy, the CR rate was 28% and 88%(χ2= 18. 75, P= 0. 000). In patients with pathological nodular and ulcer type, the CR rates with radiotherapy were higher than with chemotherapy (100%: 38%, χ2 = 7.92, P = 0. 005; and 100%: 11%,χ2 = 14.40, P = 0. 000). Multivariate analysis showed that stage and recent effect were the independent prognostic factors. Conclusions The initial radiotherapy with 50 Gy is appropriate for early stage nasal NK/T cell lymphomas. Combined chemotherapy could be used for extended stage ⅠE and ⅡE, but the outcome of CHOP regimen is poor.

早期结外NK/T细胞淋巴瘤的研究进展

结外NK/T细胞淋巴瘤(ENKTCL)是异质性强、高度侵袭性的非霍奇金淋巴瘤。尽管大多数ENKTCL患者诊断时为早期,但由于分期的局限性,预后差异较大。放疗和化疗是早期ENKTCL患者的一线治疗方法,但放疗、化疗模式及治疗时序仍存在争议。随着临床分期及预后模型的不断更新,早期ENKTCL患者倾向于接受风险适应性分层治疗...     

早期结外鼻型NK/T细胞淋巴瘤同期放化疗疗效分析

目的:探讨Ⅰ E～ⅡE期结外鼻型NK/T细胞淋巴瘤同期放化疗的疗效,并进一步分析其可行性.方法:回顾分析18例早期结外鼻型NK/T细胞淋巴瘤患者,以序贯化放疗50例为对照.18例同期放化疗患者中诱导化疗+同期放化疗+辅助化疗3例,诱导化疗十同期放化疗13例,同期放化疗十辅助化疗1例,单纯同期放化疗1例,全组放疗中位剂量54 Gy.结果:诱导化疗后的总缓解率为50.0％(8/16),治疗结束后为100.0％(18/18).同期放化疗组与对照组的5年总生存率分别为80.8％和54.3％(x2=3.66,P=0.05),5年无进展生存率(PFS)分别为75.8％和43.3％(x2=6.13,P=0.01),5年局部控制(LC)率分别为94.1％和56.7％(x2=6.32,P-0.01).同期放化疗过程中出现Ⅲ～Ⅳ度骨髓抑制率为27.8％(5/18),Ⅲ度口腔黏膜反应率为16.7％(3/18),Ⅲ度咽喉反应率为5.6％(1/18),其余不良反应均 为Ⅰ～Ⅱ度,Ⅲ～Ⅳ反应经对症处理后未影响下一步治疗.结论:同期放化疗是早期结外鼻型NK/T细胞淋巴瘤安全、有效的治疗方法,相对其他接受放疗患者有提高局部控制率和生存时间的趋势,其毒副反应可以耐受.     

鼻型NK/T细胞淋巴瘤临床病理特征及预后分析

目的探讨鼻型NK/T细胞淋巴瘤临床病理特征及预后影响因素。方法回顾性分析经病理证实的31例该病患者的临床资料。结果鼻型NK/T细胞淋巴瘤容易误诊;3年及5年生存率分别为58.1%和33.3%;随着分期增高,生存率明显下降;有B症状者或IPI评分≥2者,其生存率分别显著低于无B症状者或IPI评分<2者;综合治疗组3年生存率显著高于单纯化疗组。结论鼻型NK/T细胞淋巴瘤的诊断应结合其临床特征、形态学、免疫表型及遗传学改变综合确定;AnnArbor分期、IPI及B症状是影响预后的重要因素;综合治疗可能是目前最佳的治疗选择。     

鼻型NK/T细胞淋巴瘤研究进展

目的:总结鼻型NK/T细胞淋巴瘤的研究进展。方法:应用Medline及CNKI期刊全文数据库检索系统,检索1992-01-2007-12关于鼻型NK/T细胞淋巴瘤分子发病机制、临床病理和免疫组化研究及治疗方面的文献。最后纳入32篇。结果:鼻型NK/T细胞淋巴瘤主要发生于鼻腔及面中线部位,也可以发生于其他部位,如皮肤、胃肠道、中枢神经系统、肺以及睾丸等。病理学上,肿瘤细胞胞质CD3及CD56阳性,同时表达细胞毒性颗粒蛋白,如TIA-1等,往往也表达EBV病毒抗原。鼻型NK/T细胞淋巴瘤预后不良,易复发且对治疗不敏感。新的国际预后指数已用于评价该肿瘤的预后。从单独放疗到高剂量的化疗以及造血干细胞移植术等几种治疗手段已应用于临床。结论:鼻型NK/T细胞淋巴瘤与EB病毒有关,具有独特的临床病理特点,放化疗联合运用可提高其治疗效果。

Abstract：

Objective To retrospectively analyze the treatment results and prognostic factors in patients with primary bone lymphomas (PBL).Methods Thirty-one patients with PBL treated between April 1994 and May 2009 at Sun Yat-sen University Cancer Center were analyzed.All patients were diagnosed by pathology.Twenty-two patients had stage Ⅰ E, 4 patients had stage Ⅱ E and 5 patients had stage ⅣE diseases.One patient was treated with surgical resection alone, 1 patient with radiotherapy (RT) alone, 2 patients with chemotherapy (CT) alone and 4 patients with resection followed by chemotherapy.The remaining 23 patients received CT combined with RT.The median radiation dose was 50 Gy.Results The median follow-up time was 45.2 months.The follow-up rate was 83.9%.Nine patients had a follow-up time of 10 years.The 5-year and 10-year overall survival rates were 92% and 92%, respectively.The 5-year and 10-year disease-free survival rates were 79% and 70%, respectively.In the group who received non-combined chemoradiotherapy, the complete response rate was 50%, the incidence of progression or recurrence was 2/8 and the median recurrence time was 6.8 months.In the group who received combined chemoradiotherapy, the complete response rate was 65%, the incidence of progression or recurrence was 13% and the median recurrence time was 39.1 months.In univariate analyses, favorable prognostic factors for survival included age≤50 years (χ2=5.32,P=0.021) and ECOG PS score 0-1(χ2=5.48,P=0.019).Favorable prognostic factors for DFS included IPI score≤1(χ2=7.81,P=0.005) and ECOG PS score 0-1(χ2=18.70,P=0.000).Conclusions Treatment results of patients with PBL can be generally well.CT combined with RT appears to be the treatment of choice.RT dose ≥40 Gy is safe and feasible.Younger age and better performance status are associated with a better outcome.
