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。     

p27kip1 expression is inversely related to the grade of gastric MALT lymphoma

Background: Decreased or lost expression of the cyclin-dependent kinase inhibitor p27^kip1 protein has been found to be a poor prognostic factor in many cancers, including gastric cancer. Aim: To evaluate p27^kip1 expression in gastric mucosa-associated lymphoid tissue (MALT) and gastric B-cell lymphoma. Methods: Fifty-two cases of gastric lymphoma, mean age 68.7 yr (range 23–90 yr), 11 of chronic Helicobacter pylori-associated gastritis, and 5 of normal gastric mucosa were studied. Patients were classified into two groups. Stage IE gastric lymphomas were defined as local gastric lymphoma of MALT and more advanced stages as advanced gastric lymphoma. Twenty-three patients diagnosed as stage IE, 13 of these were low-grade and 10 diffuse large B-cell lymphoma (DLBL). Twenty-nine patients were at stage IIE or above, 18 with low-grade and 11 with DLBL. Serial sections were evaluated by immunohistochemistry after staining with antibodies against p27/Kip1 and Ki-67. Results: The proliferative index was higher in gastric DLBL than in low-grade MALT lymphomas, 57.1±31.2 vs 17.3±20.6 (p=0.0001). The mean p27^kip1 expression score for high-grade patients was significantly lower compared with that of low-grade patients, 0.5 ± 0.4 and 1.6±0.8, respectively (p=0.001). Comparative evaluation of p27^kip1 expression in malignant lymphoid cells revealed that B cells of the localized gastric DLBL patients expressed the least p27^kip1, 0.36±0.32. This value was lower than that of malignant lymphoid cells of patients with advanced DLBL, 0.64±0.53, advanced low-grade MALT lymphoma, 1.59±0.79, and localized low-grade MALT lymphoma, 1.59±0.84. In the multivariate model in which all p27^kip1 variables were entered, the expression of p27^kip1 in malignant lymphoid cells was inversely correlated with the grade of the lymphoma irrespective of the stage of the disease (p=0.0001), and significantly predicted grade: OR:0.07, 95% CI 0.07–0.31, p=0.0001. Conclusion: p27^kip1 may be a putative distinct molecular marker to differentiate between low-grade and high-grade gastric lymphoma.     

10例原发性卵巢淋巴瘤临床分析

目的探讨原发性卵巢淋巴瘤（primary ovarian lymphonla,POL）的临床表现、诊断、治疗及预后。方法对10例POL患者的临床资料进行回顾性分析。根据AnnArbor分期法,ⅡE期2例,ⅣE期8例。,所有病例均为B细胞来源的非霍奇金淋巴瘤（non—Hodgkin’s lymphoma,NHL）。7例弥漫大B细胞淋巴瘤（diffuse large B—cell lymphoma,DLBCI．）中,1例部分呈Burkitt样分化,1例部分呈免疫母细胞分化;2例为未进一步细分的B细胞来源的NHL;1例为边缘带B细胞淋巴瘤。,10例患者均采用手术、化疗、放疗联合的综合治疗,3例患者行高剂量化疗及自体造血十细胞移植。结果中位随访期32．8个月。3例患者至随访结束时仍无病生存。中位无进展生存期（progression-free survival,PFS）为20．6个月（4．8-95．0个月）,中位总生存期（overall survival,os）为33．7个月（6．8～95．0个月）。结论POL临床表现无特异性,病理类型以DLBCL为主,临床分期多为晚期,临床上均采用手术、放疗、化疗联合的综合治疗。     

Treatment outcome of radiotherapy alone versus radiochemotherapy in early stage nasal natural killer/T-cell lymphoma

This study aims to investigate the prognostic factors and long-term treatment outcome in patients with early stage nasal natural killer (NK)/T-cell lymphoma. Sixty-four patients were recruited in this study, whose clinical and laboratory data were collected from hospital records. Early stage (stage IE: 51, stage IIE: 13) nasal NK/T-cell lymphoma (NNTCL) was established according to Ann Arbor staging classification. Among these patients, 23 received radiotherapy (RT) alone, the remaining 41 cases were treated with radiochemotherapy (RCT) comprised of 1–6 cycles of anthracycline-based chemotherapeutic regimens. Results show that the median overall survival (OS) time was 41 months. The 5-year OS and progression-free survival rates were 59.2 and 52.3%, respectively. The 5-year OS rate for patients who received RT alone was 57.9%, whereas that for patients who received RCT was 61.5% (P = 0.47). There is no significant difference between two treatment modalities. Multivariate analysis showed that Eastern Cooperative Oncology Group performance status (PS) score ≥ 2, local tumor invasion out of nasal cavity, and lower complete remission (CR) rates in the initial treatment were significant unfavorable independent prognostic factors. Taken together, our study suggests that RCT did not improve the survival rate of patients with early stage NNTCL. PS score before treatment, local tumor invasion out of nasal cavity, and CR rate of the primary treatment may be independent prognostic factors among the subtype lymphoma entity.     

鼻咽非霍奇金淋巴瘤的临床与预后分析

目的 探讨鼻咽非霍奇金淋巴瘤的临床特点、治疗及国际预后指数(IPI)的应用价值。方法 回顾性分析1983—1997年间136例首程治疗的鼻咽非霍奇金淋巴瘤患者的临床资料。按照工作分类原则进行分类,高度恶性18例,中度恶性77例,低度恶性2例,未分类39例。根据Ann Arbor分期,Ⅰ期25例,Ⅱ期91例,Ⅲ期12例,Ⅳ期8例。Ⅰ期单纯放疗13例,综合治疗12例;Ⅱ期单纯放疗31例,综合治疗57例,Ⅲ和Ⅳ期以化疗为主。结果 5年和10年总生存率(OS)、癌症相关生存率(CSS)和无病生存率(OFS)分别为56．2％和48．3％,61．2％和58．0％,51．1％和46．5％。IPI为0,1及2～3分的5年CSS分别为70．9％、44．9％、30．0％(P=0．004)。Ⅰ期化放疗综合治疗和单纯放射治疗的5年CSS分别为82．2％和83．1％,10年CSS分别为82．2％和66．4％,差异无显著性(P=0．779)。Ⅱ期综合治疗和单纯放射治疗5年CSS分别为70．9％和46．0％,10年CSS分别为65．4％和46．0％,差异有显著性(P=0．04)。Cox多因素分析显示,影响预后的因素为Ann Arbor分期、B组症状和IPI。结论 IPI是判断原发于鼻咽非霍奇金淋巴瘤预后的重要指标,Ⅱ期鼻咽非霍奇金淋巴瘤应考虑综合治疗。     

Combined chemotherapy and external beam radiation for stage IE and IIE natural killer T-cell lymphoma of nasal cavity

To evaluate the outcome of CHOP chemotherapy and radiotherapy in Stage IE and IIE nasal natural killer (NK)/T-cell lymphoma, 53 patients with stage IE and IIE nasal NK/T-cell lymphoma were studied. By the Ann Arbor Lymphoma Staging Classification, 41 patients (77%) had Stage IE disease and 12 patients (23%) had Stage IIE disease. All patients were treated curatively using chemotherapy, followed by radiotherapy. Chemotherapy consisted of up to six cycles of the standard CHOP based regimen. The median radiation dose to the tumor bed was 45 Gy for all patients. The median follow-up for all 39 surviving patients was 30.2 months (range, 6 - 104 months). Twenty-six patients had complete response after chemotherapy, and all patients who completed first line chemotherapy achieved complete response after radiotherapy. The 2-year overall survival and progression-free survival rates were 75.6% and 61.8%, respectively. Multivariate analysis revealed that perforation as a presenting symptom, elevated pretreatment serum lactate dehydrogenase level, and ECOG performance status >or=2 were significant independent prognostic factors for this group of patients. Combined chemotherapy followed by involved field radiation produced suboptimal outcome for patients with early stage nasal NK/T-cell lymphoma. Further investigations, preferably prospective clinical trials, for more efficacious treatment strategies are needed to improve the treatment outcome of this malignancy.     

Mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach

Treatment of patients with early stage gastric mucosa-associated lymphoid tissue (MALT) remains undefined. We began a controlled clinical trial to evaluate efficacy and toxicity of the most common therapies. Two hundred and forty-one patients with gastric low-grade MALT lymphoma in early stage (IE and IIE) were randomized to surgery (80 cases), radiotherapy (78 cases), and chemotherapy (83 cases). With a median follow-up of 7.5 yr, actuarial curves at 10 yr showed that event-free survival was 52% in patients treated with surgery, 52% in radiotherapy arm, and 87% in the chemotherapy group (p<0.01). However, overall survival did not showed any statistical differences: 80%, 75% and 87%, respectively (p=0.4). Acute and late toxicities were mild. No death-related treatments were observed. No clear differences were observed between the most common therapies in patients with primary gastric MALT lymphoma in early stages, probably because this type of lymphoma has an high response rate to salvage treatment after failure to local treatment (surgery and radiotherapy). Thus considered, chemotherapy alone is an effective and safe therapeutic approach in this setting of patients. Surgery or radiotherapy will be reserved to patients that are not candidates for chemotherapy.     

Primary Breast Lymphoma: Analysis of 55 Cases of the Spanish Lymphoma Oncology Group

IntroductionPrimary breast lymphoma is a rare form of localized extranodal lymphoma, which affects the mammary glands unilaterally or bilaterally, and can also affect the regional lymph nodes.Materials and MethodsWe reviewed 55 patients, with disease stages IE and IIE, diagnosed in 16 Spanish institutions between 1989 and 2016. A serial of clinical variables and treatment were collected, and overall survival (OS) and progression-free survival (PFS) were calculated.ResultsOf the 55 patients, 96.4% were women with an average age of 69 years. A total of 53 patients corresponded to non-Hodgkin lymphoma (NHL), of whom 36.3% had lymph node involvement upon diagnosis. Of the patients, 58.2% were stage IE, and 41.8% were stage IIE. Treatments received included radiotherapy (36.3%), chemotherapy (85.5%), and rituximab (in 38 of the 45 patients with NHL treated with chemotherapy). In all, 82.2% of complete responses were achieved. OS and progression-free survival at 5 years in NHL patients was 76% and 73%, respectively.ConclusionCurrent treatments (chemotherapy, immunotherapy, and radiotherapy) achieve good control of the disease, with an OS of 5 years in 80% of the patients, although there is no consensus in treatment, given the scarce incidence of these lymphomas.     

Low-grade mucosa-associated lymphoid tissue lymphoma: a retrospective analysis of 97 patients by the Hellenic Cooperative Oncology Group (HeCOG).

BACKGROUND: The aim was to examine characteristics and treatment results of patients with mucosa-associated lymphoid tissue (MALT) non-Hodgkin's lymphomas. PATIENTS AND METHODS: Epidemiological and clinical features of 97 patients with MALT lymphoma from the Hellenic Cooperative Oncology Group registry were analysed retrospectively for their prognostic significance in progression-free survival (PFS) and overall survival (OS). Comparisons were made between patients with gastric and nongastric sites of primary lymphoma and between different therapeutic modalities. RESULTS: Sixty-five patients presented with gastric and 32 with nongastric lymphomas. The most frequent locations of nongastric lymphomas were the bowel, lung and parotid. Gastric lymphomas occurred more frequently in males and younger patients compared with nongastric lymphomas. Seventy-four per cent of patients had early (Ann Arbor stages I-II) and 26% had advanced (stages III-IV) disease. The median PFS for the entire population was 44 months. At 5 years, 47% of patients were progression free and the OS rate was 80%. The most reliable prognostic factor for PFS and OS was the Ann Arbor stage; 5-year PFS was 67% versus 13% and 5-year OS 91% versus 51% for patients with early versus advanced disease, respectively (P < 0.001). Of the patients treated with chemotherapy only, 87% achieved an objective response and 71% complete response. Surgery did not offer survival benefit compared with chemotherapy in localised gastric lymphoma. CONCLUSION: MALT lymphomas represent a distinct disease entity with widespread extranodal origin, indolent clinical course and high chemosensitivity. Ann Arbor stage was the most reliable prognostic and predictive factor.     

Relapse patterns of localized non-Hodgkin's lymphoma of the head and neck after clinical remission: results of a strict follow-up procedure

Background. No effective follow-up strategy for non-Hodgkin's lymphoma (NHL) has been identified to date. The aim of this study was to assess the value of a strict follow-up procedure in patients with NHL after they showed clinical remission. Methods. One hundred and twenty-one patients with localized NHL of the head and neck who had achieved clinical remission after radiation therapy and/or chemotherapy were followed with a strict follow-up strategy (consisting of a schedule of frequent office visits, imaging studies, and blood tests, even if the patient was asymptomatic). Results. Thirty-nine patients relapsed after remission. Twenty-two (56.4%) of the relapses were associated with symptoms. In the 17 patients with asymptomatic relapses (43.6%), an abnormal physical examination result initially indicated relapse in 10 patients. The other tests that initially indicated relapse included scheduled computed tomography scans (3 patients), scheduled gallium scans (2 patients), and serum lactate dehydrogenase levels (2 patients). According to the Ann Arbor stage at relapse, 72.7% of the patients with symptomatic relapses were stage III or IV, while 70.6% of the patients with asymptomatic relapses were stage I or II. Conclusions. These results indicate that a strict follow-up procedure is effective in detecting asymptomatic relapses, which generally involve a smaller tumor load than symptomatic relapses.

探讨胃黏膜相关淋巴样组织淋巴瘤的临床表现、病理特征和治疗方法。方法:回顾性分析1990年7月至2008年5月间42例胃MALT淋巴瘤的病理特征和临床分期等资料,并按治疗方式不同划分为单纯根除Hp组（7例）、单纯手术组（9例）、手术+根除Hp组（20例）、手术+放、化疗组（6例）,对各治疗组随访结果使用Kaplan-Meier方法进行生存率分析,Log Rank检验评估各组间的统计学差异。结果:全组患者均接受胃镜检查,确诊率26.2%（11/42）,HP染色阳性率70.6%（24/34）。免疫表型分析证实全部为B细胞性淋巴瘤。全组Cotswolds改良Ann Arbor分期:ⅠE2期17例,ⅡE1期16例,ⅡE2期6例,ⅢE期2例,Ⅳ期1例。各组5年生存率分别为100%、83.7%、82.4%及43.0%（P=0.027）。结论:胃MALT淋巴瘤的临床表现和辅助检查均无明显特异性,故初治时接受手术治疗的患者较多。病理确诊者可首选根除Hp治疗,疗效与手术无异;晚期患者可在术后选择放、化疗等综合治疗,但远期生存率相对较差。      

30例早期鼻腔NK/T细胞淋巴瘤的生物学特性

目的:回顾性分析30例早期鼻腔NK/T细胞淋巴瘤的生物学行为特点,为临床放疗靶区的设计提供参考。方法:收集2005年3月至2013年9月间收治的30例经病理证实为早期原发于鼻腔的NK/T细胞淋巴瘤患者的资料,根据Ann Arbor分期标准,所有患者均为IE/IIE期且都有影像检查资料可查,并以影像学为标准分析邻近受侵器官和结构的数目,同时分析颈部淋巴结的转移情况。结果:鼻腔周围结构受侵患者占所有患者的比例为76.7%（23/30）,其具体受侵如下:上颌窦为36.6%、筛窦与鼻咽同为30%、鼻翼为20%、翼突与蝶窦同为10%,翼腭窝及额窦、硬腭、眼眶、口咽同为3.3%;头颈部淋巴结转移的患者占所有患者的比例为46.7%（14/30）,其具体转移如下:I区与II区同为26.7%,III区为10%,VIIa为6.7%,IV区与IX同为3.3%。结论:在早期鼻腔NK/T细胞淋巴瘤放射治疗时,其靶区的勾画应该考虑受侵和转移几率均较高的结构和区域。     

Primary gastric non-Hodgkin's lymphoma. A retrospective clinico-pathological study.

Prognostic factors and treatment results were analysed in 72 consecutive patients with primary gastric lymphoma treated between 1970 and 1985. There were 37 patients in stage IE, 17 in IIE, 3 in IIES and 15 in stage IV. Histopathological re-evaluation and classification according to the TNM system were performed. We found that disseminated disease (stage IV), serosal penetration (T3), involvement of adjacent organs (T4) and extensive abdominal lymph node involvement (N3) were poor prognostic factors. Neither histological malignancy grading, nor the appearance of lympho-epithelial lesions were significantly associated with relapse-free survival. Forty-six patients with 'limited localized' disease (stage IE, IIE, N3 excluded) received potentially curative treatment (surgery, radiotherapy, chemotherapy or combinations thereof), of whom 85% remained relapse-free. Thirty-four patients did only get local treatment (surgery and/or radiotherapy) with curative potential, the relapse-free survival rate was 85%. We conclude that primary gastric lymphoma stage IE and IIE (N3 excluded) is often a truly localized disease that can be cured with local therapy.     

疗前血清Hb水平在早期结外鼻型NK/T细胞淋巴瘤中的预后价值

目的 探讨治疗前血清Hb水平对早期结外鼻型NK/T细胞淋巴瘤预后的影响。 方法 回顾分析2000—2015年间收治的 175例Ⅰ、Ⅱ期结外鼻型NK/T细胞淋巴瘤。纳入标准为原发病灶位于上消化呼吸道,不合并其他恶性疾病,治疗及随访记录完整病例纳入分析。接受单纯化疗 67例、单纯放疗 8例、放化疗 100例。Kaplan-Meier法计算生存率,Logrank法单因素分析,Cox模型多因素分析。 结果 175例患者的变量单因素分析显示疗前血清Hb水平(≥120 g/L)、LDH水平(正常)、ECOG评分(0~1)、Ann Arbor分期(Ⅰ_{E)、接受放疗显著提高PFS及OS (P=0.000~0.046)。多因素分析显示血清Hb水平、LDH水平、ECOG评分、Ann Arbor分期是患者PFS、OS影响因素(P=0.000~0.040)。 结论 疗前Hb≥120 g/L者预后好于<120 g/L者。}     

Non-Hodgkin's lymphoma of the ocular adnexa

This study investigates the relationship between the clinical features of lymphoma in the ocular adnexal region and the revised European and American lymphoma (REAL) classification. Specimens from 41 patients with ocular adnexal lymphoproliferative disease were reassessed pathologically using the REAL classification. Thirty-two patients with primary non-Hodgkin's lymphomas (NHL) were included in the study, almost all of them having been treated with radiotherapy with or without chemotherapy. Seven of the 32 patients with NHL showed distant recurrence after treatment: 3 out of 26 with extranodal marginal zone B-cell lymphoma, and 4 with other types of NHL. Although the three patients with recurrent marginal zone B-cell lymphomas all survived, other patients with recurrent lymphomas died of disease. The REAL classification provides a good indication of tumor control probability and survival of patients with ocular adnexal NHL. Radiation therapy is an effective treatment modality for extranodal marginal zone B-cell lymphoma of the ocular adnexa.     

D-二聚体水平与非霍奇金淋巴瘤患者预后关系的研究

  目的  本研究拟探讨D-二聚体升高与非霍奇金淋巴瘤（Non-Hodgkin Lymphoma NHL）患者总生存之间的关系。  方法  回顾性分析2000年1月至2009年12月天津医科大学附属肿瘤医院收治的经病理证实的NHL 425例,分析患者临床病理特征、D-二聚体及国际预后指数（the International prognostic index,IPI）对总生存的影响。  结果  血浆D-二聚体水平与IPI评分明显相关。低、中、高水平D-二聚体组5年生存率分别为97.4%,86.1%,35.0%（P < 0.05）。与IPI为0或1的患者相比,IPI≥4分者预后较差（P < 0.05）。Ann Arbor分期、病理类型、D-二聚体水平以及IPI评分是影响总生存的主要因素,多元分析表明IPI评分、血浆D-二聚体水平是独立预后因子。  结论  高水平的D-二聚体是NHL患者预后差的标志物。      

Primary spinal epidural lymphoma: patients' profile, outcome, and prognostic factors: a multicenter Rare Cancer Network study

PURPOSE: To assess the clinical profile, treatment outcome, and prognostic factors in primary spinal epidural lymphoma (PSEL). METHODS AND MATERIALS: Between 1982 and 2002, 52 consecutive patients with PSEL were treated in nine institutions of the Rare Cancer Network. Forty-eight patients had an Ann Arbor stage IE and four had a stage IIE. Forty-eight patients underwent decompressive laminectomy, all received radiotherapy (RT) with (n = 32) or without chemotherapy (n = 20). Median RT dose was 36 Gy (range, 6-50 Gy). RESULTS: Six (11%) patients progressed locally and 22 (42%) had a systemic relapse. At last follow-up, 28 patients were alive and 24 had died. The 5-year overall survival, disease-free survival, and local control were 69%, 57%, and 88%, respectively. In univariate analyses, favorable prognostic factors were younger age and complete neurologic response. Multivariate analysis showed that combined modality treatment, RT volume, total dose more than 36 Gy, tumor resection, and complete neurologic response were favorable prognostic factors. CONCLUSIONS: Primary spinal epidural lymphoma has distinct clinical features and outcome, with a relatively good prognosis. After therapy, local control is excellent and systemic relapse occurs in less than half the cases. Combined modality treatment appears to be superior to RT alone.     

Non-Hodgkin's Lymphoma of the Thyroid: A clinical study of twenty-two cases

Non-Hodgkin's lymphoma (NHL) of the thyroid gland is a rare disease. In the present study, the survival rate and characteristics were retrospectively analyzed in 22 patients with stage IE and IIE thyroid NHL treated with radiotherapy with or without combination chemotherapy. Seventeen NHL had histological evidence of lymphoma of mucosa-associated lymphoid tissue (MALT) type. The 5-year survival rate was 85% in all patients, with 100% and 63% respectively, for stage IE and stage IIE patients. The highly significant factor correlated with decreased determinate survival was concomitant stridor.     

Treatment Outcomes of Low-grade Lymphoma of the Orbit

AimsRadiation therapy can be used with curative intent in patients with low-grade orbital non-Hodgkin's lymphoma (NHL) stages IE and IVE (limited to the bilateral orbits). This study evaluated local control and survival outcomes of patients with unilateral or bilateral orbital lymphoma treated in a provincial population.Materials and methodsThe study subjects were 176 patients with low-grade orbital or conjunctival lymphoma referred for management from 1980 to 2016. Demographic, tumour and treatment characteristics were abstracted by chart review. Recurrence-free survival (RFS) and overall survival were assessed with competing risks analysis and Gray's test.ResultsThe median follow-up was 8.5 years (range 0.4–29.5 years). The median age at diagnosis was 65 years (range 20–97 years). The most common histological subtype was mucosa-associated lymphoid tissue (MALT) (73%). Stage IVE accounted for 20.5% of the cohort. Orbital radiation therapy was used in 122 patients with stage IE (87%) and 12 patients with stage IVE (28%). The median dose was 25 Gy (range 2–35 Gy). Other treatments were antibiotics (seven patients), chemotherapy (10 patients), radioimmunotherapy (six patients), surgery (three patients) and observation (16 patients). Within the group treated with orbital external beam radiation therapy (EBRT) there were no local recurrences. Among those with stage IE NHL, EBRT was associated with improved local RFS (P ≤ 0.001) but did not have an impact on contralateral or distant RFS. In patients with stage IVE NHL limited to the bilateral orbit, bilateral EBRT was associated with improved RFS (P = 0.012) but did not affect distant recurrences or overall survival.ConclusionThere were no local recurrences after EBRT for stage IE and IVE orbital low-grade NHL. The treatments offered over the study period varied, but only EBRT for stage IVE disease improved RFS. This supports EBRT as the preferred primary treatment for patients with localised orbital low-grade lymphoma, including those with bilateral disease.     

腭扁桃体非霍奇金淋巴瘤70例临床分析

 目的 探讨原发于腭扁桃体的非霍奇金淋巴瘤（NHL）的临床疗效及其预后因素。方法 回顾性分析1993年11月至1999年8月收治的70例原发于腭扁桃体的NHL的临床资料。根据Ann Arbor分期，Ⅰ期12例，Ⅱ期39例，Ⅲ期15例，Ⅳ期4例。根据1981年国际工作分类：低度恶性8例，中度恶性28例，高度恶性34例。单纯化疗组30例，单纯放疗组3例，综合治疗组37例。结果 全组总体生存率为56.3 ％，其中1、3、5年生存率分别为82.5 ％、67.3 ％、58.5 ％。高度恶性患者单纯化疗、单纯放疗、综合治疗的总体生存率分别为20.0 ％、0、52.6 ％（P＜0.05）。多因素分析证明，病理类型和近期疗效是影响预后的独立因素。结论 放化疗综合治疗可提高腭扁桃体NHL的疗效，病理类型和近期疗效是腭扁桃体NHL重要的预后因素
