129例原发鼻腔非霍奇金淋巴瘤的预后分析

背景与目的：原发鼻腔非霍奇金淋巴瘤（non-Hodgkin’s lymphoma,NHL）预后较差．远处转移和局部复发率均较高．目前本病尚无标准治疗原则。本研究主要探讨影响原发鼻腔NHL的预后因素。方法：1996年1月至2002年12月共收治129例经病理证实的原发鼻腔NHL。116例经病理形态学诊断为鼻腔NK／T细胞淋巴瘤。根据Ann Arbor分期,ⅠE期102例,ⅡE期22例,ⅣE期5例。124例ⅠE／ⅡE期患者单纯放疗22例,单纯化疗7例,45例放疗后化疗,50例化疗后放疗。5例ⅣE期以化疗为主。结果：全组5年总生存率（overall survival,OS）和无病生存率（disease-freely survival,DFS）分别是68．0％和55．8％。ⅠE期和ⅡE期患者的5年OS分别是71．7％和70．6％（P=0．77）,DFS分别是60．9％和47．0％（P=0．09）。首程治疗后完全缓解（complete response,CR）的患者5年OS为83．1％,而未达CR患者的5年OS为18．0％（P〈0．01）,相应5年DFS分别为68．0％和15．5％（P〈0．01）。国际预后指数（international prognostic index,IPl）评分为0,1和≥2的5年OS分别为81．1％、60．1％和14．3％（P〈0．01）,DFS分别为68．8％、44．6％和22．5％（P〈0．01）。38例患者治疗中进展或疗后复发,远处结外器官复发占78．9％,是治疗失败主要原因。单因素分析显示,首程治疗后的CR率、一般状态评分（performance status,PS）、IPI和修订后IPI与预后相关。多因素分析显示仅治疗后的CR率是独立预后因素。结论：治疗后的CR率是影响原发鼻腔NHL的重要预后因素,原因以远处病灶治疗失败为主。     

ⅠE～ⅡE期鼻腔NK/T细胞淋巴瘤的放疗效果分析

目的 分析ⅠE～ⅡE期鼻腔NK／T细胞淋巴瘤以放疗为主的治疗结果。方法 1983年1月至2003年12月共收治105例经免疫组化证实的Ⅰ～Ⅱ期原发鼻腔T／NK细胞淋巴瘤。根据Ann Arbor分期，Ⅰ期83例，ⅡE期22例。根据原发肿瘤局限于鼻腔或直接侵犯邻近器官，将Ann ArborⅠE期分为局限ⅠE期（37例）和超腔ⅠE期（46例）。全组31例接受单纯放疗，34例放疗后化疗，37例化疗后放疗，3例单纯化疗。结果 全组5年总生存率（OS）和无进展生存率（PFS）分别为71％和59％。ⅠE、ⅡE期5年OS分别为78％、46％（P〈0．01），5年PFS分别为63％、40％（P〈0．01）。91例（87％）治疗后达完全缓解（CR）。接受先放疗的65例中，54例达CR（83％）；而先接受化疗的40例中，仅有8例达CR（20％）。接受单纯放疗或综合治疗的102例中，单纯放疗的5年OS、PFS分别为66％、61％，综合治疗的分别为76％、61％（P〉0．05）。结论 早期鼻腔NK／T细胞淋巴瘤对常规化疗的反应率明显低于放疔。放疗为主的治疗能取得较好治疗效果，化疗加入放疗未显著改善患者的生存率。     

Ⅱ期非霍奇金淋巴瘤治疗方法的选择(附268例分析)

目的 探讨Ⅱ期非霍奇金淋巴瘤（non-Hodgkin‘s lymphoma,NHL)有效的治疗方法。方法 对268例Ⅱ期NHL患者分别采用单纯放疗、综合治疗（包括放疗＋化疗、化疗＋放疗＋化疗和化疗＋放疗）等单纯化疗治疗。结果 Ⅱ期高度恶性NHL经化疗＋放疗＋化疗治疗后,1,2,3,4,5,6年生存率分别为95．1％、87．8％、87．8％、85．4％、82．9％和53．6％,6年复发率为26．8％,与单纯放疗、放疗＋化疗和化疗＋放疗组相比,生存率有明显提高（P＜0．01）,6年复发率降低（P＞0．05）。Ⅱ期中度恶性NHL患者经化疗＋放疗＋化疗治疗后,1,2,3,4,5,6年生存率分别为89．3％、75．0％、67．8％、60．6％、57．1％和46．4％,6年复发率为35．7％,与单纯放疗、放疗＋化疗和化疗＋放疗组相比,生存率有所提高（P＞0．05）,6年复发率降低（P＞0．05）。Ⅱ期期低度恶性NHL患者经单纯放疗及综合治疗后,1,2,3,4,5,6年生存率及6年复发率相近。结论 对Ⅱ期中,高度恶性NHL患者应采用化疗＋放疗＋化疗治疗,尤其对于高度恶性者,Ⅱ期低度恶性NHL患者应采用单纯放疗。     

84例鼻型NK/T细胞淋巴瘤的治疗与预后分析

目的 分析鼻型NK/T细胞淋巴瘤的临床特征、不同治疗方法的疗效及影响预后的因素.方法 回顾性分析经病理证实的84例鼻型NK/T细胞NHL患者的临床资料,其中48例经免疫组化证实.根据Ann Arbor分期,Ⅰ期46例,Ⅱ期19例,Ⅲ期16例,Ⅳ期3例.单纯放疗29例,单纯化疗5例,放疗、化疗结合50例.预后判断采用Cox多因素回归模型分析.结果 全组5年总生存（OS）和无病生存（DFS）率分别为48.8%与35.7%.首程治疗后达CR的5年OS为59.4%,未达CR的5年OS为15.0%（P＜0.01）.单纯化疗中1例达CR（20.0%）,单纯放疗21例达CR（72.4%）,放疗、化疗结合42例达CR（84.0%）,放疗、化疗结合与单纯放疗后达CR明显高于单纯化疗（P＜0.01）.单纯放疗和放疗、化疗结合的5年OS率分别为44.8%和54.0%（P＞0.05）,均明显高于单纯化疗20.0%（P＜0.05）;单纯放疗和放疗、化疗结合的5年DFS分别为34.5%、40.0%,明显高于单纯化疗（P＜0.01）.多因素回归分析显示：IPI、首程CR、B症状、鼻中隔和（或）硬腭穿孔及治疗方法为影响生存的独立预后因素,其中以IPI评分最明显.结论 对鼻型NK/T淋巴瘤采用单纯化疗疗效差,而放疗、化疗结合疗效较好,但远期生存情况仍不满意.

原发鼻腔T/NK-T细胞非霍奇金淋巴瘤34例临床分析

 目的 探讨原发鼻腔T细胞性非霍奇金淋巴瘤（NHL）的临床特点及治疗。方法 回顾分析1997年1月至2001年12月收治的鼻腔T细胞性NHL34例。其中23例用化、放疗联合治疗,9例用单纯化疗,2例未治疗。所有化疗均采用标准CHOP方案。结果 单纯化疗组有效率为44.4 ％,CR率为22.2 ％;化、放联合治疗组有效率为100.0 ％,CR率86.9 ％。全组1年、3年、5年生存率分别为52.9 ％,41.2 ％,18.3 ％。化、放联合治疗组5年生存率高于单纯化疗组;局限于鼻腔（ⅠE期）者,5年生存率高于有远处播散者（>ⅠE期）。结论 原发性鼻腔T细胞NHL 预后不良,用标准CHOP方案化疗疗效差,联合化、放疗有助于改善预后。     

37例鼻腔NK/T细胞淋巴瘤临床分析

目的分析鼻腔NK/T细胞淋巴瘤的临床特征、不同治疗方法的疗效及影响预后的因素。方法回顾性分析1999年12月至2008年4月收治的37例经病理证实的鼻腔NK/T细胞淋巴瘤患者的临床资料。根据AnnArbor分期,Ⅰ期17例,Ⅱ期15例,Ⅲ期1例,Ⅳ期4例。单纯放疗8例,单纯化疗9例,其余20例采用放化疗联合治疗。单因素分析采用Kap lan-M e ier法,多因素分析运用Cox比例风险模型。结果全组中位生存时间27月,3年总生存（OS）率为50.0%,放化疗联合、单纯放疗、单纯化疗3年生存率分别为77.8%、50.0%、0%。单纯放疗、放化疗联合治疗后3年生存率明显高于单纯化疗（P〈0.01）;放化疗联合与单纯放疗治疗后3年生存率无明显差异（P〉0.05）。单纯化疗CR 1例（11.1%）,单纯放疗CR 6例（75.0%）,放化疗联合CR 16例（80.0%）,单纯放疗、放化疗联合治疗后CR率明显高于单纯化疗（P〈0.01）;放化疗联合与单纯放疗治疗后CR率差异无统计学意义（P〉0.05）。单因素分析显示,PS评分、IPI、LDH水平、临床分期、治疗模式、首程治疗后CR率等与预后相关。多因素分析显示,首程治疗后CR率、PS评分是鼻腔NK/T细胞淋巴瘤预后不良的独立因素。结论鼻腔NK/T细胞淋巴瘤单纯放疗、放化疗联合近期疗效显著优于常规化疗,化疗加入放疗并未改善生存率。首程治疗后CR率、PS评分可作为判断鼻腔NK/T细胞淋巴瘤预后的参考因素。

Early stage nasal NK/T-cell lymphoma: clinical outcome,prognostic factors,and the effect of treatment modality

PURPOSE: To determine the clinical outcome, prognostic factors, and effect of adding combination chemotherapy to radiation therapy on disease control and survival in early stage nasal natural killer (NK)/T-cell lymphoma. METHODS AND MATERIALS: A retrospective "intent to treat" analysis was carried out on 79 patients treated consecutively with curative intent between 1977 and June 2001. They all had early stage (Ann Arbor Stage I(E): 63, II(E):16) nasal NK/T-cell lymphoma. Sixty-one were planned for combined modality treatment (CMT); radiotherapy alone (RT) was intended for 18. Three to 6 cycles of anthracycline-containing regimens were aimed at for patients intended for CMT. Patients selected for RT were generally older or treated during the earlier part of the study period. RESULTS: The overall complete response (CR) rate was 68.4% (54/79), of whom 44.4% (24/54) relapsed after 54.9 months median follow-up of the survivors. The 5-year disease-free survival (DFS) and overall survival (OS) rates were 35.5% and 37.9%, respectively. On multivariate analysis, good performance status (Eastern Cooperative Oncology Group [ECOG] <2) was shown to be a significant favorable factor for DFS (p = 0.011), whereas good performance status (ECOG <2) and Ann Arbor Stage I(E) disease were shown to be significant favorable factors for OS (p = 0.001 and p = 0.013, respectively). The type of intended treatment was not a significant factor for DFS (5-year DFS CMT vs. RT = 35.8% vs. 30.5%, p = 0.795) or OS (5-year OS CMT vs. RT = 40.3% vs. 29.8%, p = 0.693) though only 2 of the 16 Stage II(E) patients were intended for RT alone. Resistance to treatment, especially to chemotherapy, was common. Of 61 patients intended to be given CMT, 31 showed disease progression while receiving chemotherapy, of whom 17 progressed locoregionally. Nine of the latter group were rendered CR by salvage radiotherapy. CONCLUSIONS: The overall outcome in early stage nasal NK/T-cell lymphoma is poor. Performance status and Ann Arbor stage are significant factors influencing DFS and OS. The addition of anthracycline-containing chemotherapy to radiotherapy does not appear to confer any survival benefit in Stage I(E) patients. Therefore, radiation therapy remains the mainstay of treatment for this lymphoma type.     

The clinical study of extranodal natural killer cell lymphoma, nasal type

To analyze the clinical characteristics, treatment of extranodal NK/T-cell lymphoma, nasal type, the term "nasal type" describes in the nasal cavity and also in the extranasal sites. There were 82 patients with nasal NK/T lymphoma (group 1) and 11 patients with extranasal NK/T lymphoma (group 2). In group 1, 4 patients gave up treatment. Five patients received radiotherapy (RT) alone. Fifty-seven patients were treated with combination of chemotherapy and RT. Sixteen patients received chemotherapy alone. Most patients (82.9%) had stage I/II disease and a high frequency (about one-third) of B symptoms. The CR rate was 53.8%. The OS rate was 62.8% (49/78 cases). Three patients died in relation to L-asparaginase. Three patients with late relapses occurred at 10 and 17 years from CR, respectively. In group 2, except that one patient received chemoradiotherapy, 10 patients received chemotherapy. Seven patients died. The OS rate was 36.4%. Our study suggested that nasal and extranasal variants of extranodal NK/T lymphoma, nasal type represented different clinical behavior and prognosis. For comparison, extranasal NK/T lymphoma is more aggressive and higher mortality than nasal NK/T lymphoma.

Early locoregional high-dose radiotherapy is associated with long-term disease control in localized primary angiocentric lymphoma of the nose and nasopharynx.

Nasal NK/T cell is a rare form of usually localized non-Hodgkin's lymphoma (NHL) which generally carries a poor prognosis when treated with conventional NHL chemotherapy protocols. We reviewed 20 consecutive localized stage I/II nasal NK/T cell lymphomas treated at our institution over a 29 year period. Median age was 44 (range 23-71). Front-line therapy was generally radiotherapy alone (35-70 Gy) before 1980 and combination chemotherapy after 1980. Six patients were treated with first-line radiotherapy and they achieved complete remission (CR). Two subsequently received combination chemotherapy. Five of those patients remained in complete remission, after 97+ to 277+ months. Twelve patients were treated with first-line chemotherapy including CHOP or CHOP-like regimen in seven cases, and COP in five cases. Only three of them achieved CR, five had partial response and four had progressive disease. Five of the seven patients treated with CHOP did not achieve complete remission. The nine patients who failed to achieve CR with chemotherapy subsequently received salvage radiotherapy but only two of them obtained CR. Finally, two patients were treated with alternated chemotherapy and radiotherapy and achieved CR, which persisted after 14+ and 26+ months. Median survival was not reached in patients who received front-line radiotherapy, and was 35 months in patients who received front-line chemotherapy. These findings confirm that chemotherapy gives a low complete remission rate in localized nasal NK/T cell lymphoma. By contrast, first-line radiotherapy seems to give favorable results, whereas its results are poorer when administered after resistance to chemotherapy. Whether the use of chemotherapy after radiotherapy, or alternated chemotherapy-radiotherapy regimens give better clinical results than radiotherapy alone will have to be evaluated prospectively in this type of NHL.     

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.     

Treatment results and prognostic factors in primary thyroid lymphoma patients: a Rare Cancer Network study

Background: This study analyzed prognostic factors and treatment outcomes of primary thyroid lymphoma.Patients and Methods: Data were retrospectively collected for 87 patients (53 stage I and 34 stage II) with median age 65 years. Fifty-two patients were treated with single modality (31 with chemotherapy alone and 21 with radiotherapy alone) and 35 with combined modality treatment. Median follow-up was 51 months.Results: Sixty patients had aggressive lymphoma and 27 had indolent lymphoma. The 5- and 10-year overall survival (OS) rates were 74% and 71%, respectively, and the disease-free survival (DFS) rates were 68% and 64%. Univariate analysis revealed that age, tumor size, stage, lymph node involvement, B symptoms, and treatment modality were prognostic factors for OS, DFS, and local control (LC). Patients with thyroiditis had significantly better LC rates. In multivariate analysis, OS was influenced by age, B symptoms, lymph node involvement, and tumor size, whereas DFS and LC were influenced by B symptoms and tumor size. Compared with single modality treatment, patients treated with combined modality had better 5-year OS, DFS, and LC.Conclusions: Combined modality leads to an excellent prognosis for patients with aggressive lymphoma but does not improve OS and LC in patients with indolent lymphoma.
