目的 观察局部晚期宫颈癌根治性子宫切除术加术前同期放化疗(CRCT)、单纯放疗(RT)的疗效,并分析影响预后的因素。方法 回顾分析2006—2011年收治的 182例Ⅰ_B2~Ⅲ_B期宫颈癌患者资料,其中 59例RT,123例术前每周顺铂40 mg/m²同期RT,放疗剂量 40~50 Gy分 20~25次。新辅助治疗后 2~3周行全子宫、双附件及盆腔淋巴结切除术。采用Cox法行多因素预后分析。结果 随访时间满 3年者为 69例。肿瘤直径≥4.5 cm时术前CRCT与RT的 3年无进展生存(PFS)、总生存(OS)率均相似(χ²=1.84、1.56,P=0.176、0.221),<4.5 cm时术前CRCT比RT的PFS、OS率高(χ²=5.22、4.81,P=0.022、0.018)。全组 3年PFS、OS率分别为92.0%、93.8%。Cox分析显示肿瘤直径(<6 cm与≥6 cm)是PFS、OS的影响因素(χ²=2.56、4.06,P=0.011、0.007),年龄(<48岁与≥48岁)是OS的影响因素(χ²=4.86,P=0.046),术后淋巴结状况(是否转移)是PFS的影响因素(χ²=1.04,P=0.010)。     

98例套细胞淋巴瘤临床特点及预后分析

  目的  探讨套细胞淋巴瘤（mantle cell lymphoma，MCL）患者的临床特点、不同治疗方案的疗效及预后分析。   方法  回顾性分析2005年1月至2013年12月北京大学肿瘤医院收治的98例MCL患者资料，结合临床特征和治疗方案进行相关预后分析。   结果  98例患者中位发病年龄61岁，男女比例2.9:l，Ann Arbor分期Ⅲ~Ⅳ期患者为85例，占86.8%。骨髓累及者46例（46.9%）。消化道为最常见的结外侵犯器官，共25例患者（25.5%）出现消化道侵犯。53例患者接受R-CHOP方案一线治疗，预期3年生存率为61.4%；14例患者接受自体造血干细胞移植（ASCT）治疗，预期5年生存率为92.3%，其总生存期显著高于使用R-CHOP方案治疗的患者（75.5个月vs. 43.6个月，P=0.039）。年龄>60岁、血沉高于正常、LDH高于正常、B症状、Ki-67≥25%、病理存在母细胞或大B细胞转化均提示预后不佳（P < 0.05）。   结论  MCL以晚期多见，常伴有骨髓及结外病变，单纯R-CHOP方案不能获得满意疗效，ASCT治疗MCL的疗效好于常规化疗，且安全性较高。年轻患者应该选择作为一线巩固治疗。      

46例乳腺巨大恶性肿瘤切除术后经皮瓣修复缺损者的预后分析

目的分析经自体皮瓣修复乳腺巨大恶性肿瘤术后缺损者的预后及相关因素。 方法回顾性分析2012年4月至2018年5月中山大学孙逸仙纪念医院收治的46例乳腺巨大恶性肿瘤患者的临床资料。患者接受局部切除术后行自体皮瓣修复缺损。根据不同病理类型、是否伴有远处转移、切缘能否达到阴性以及治疗反应性进行亚组分析,采用Log-rank检验分析不同亚组的疾病无进展生存(PFS)和OS情况;采用单因素和多因素Cox比例风险回归模型分析PFS和OS的影响因素。 结果46例患者中,乳腺间叶恶性肿瘤患者7例,其余39例为乳腺癌患者(luminal B型18例,HER-2阳性乳腺癌11例,三阴性乳腺癌10例)。单因素分析发现：(1)乳腺间叶恶性肿瘤患者中位PFS和OS分别为28.5个月(18.1～38.7个月)和28.5个月(18.1～38.9个月), luminal B型乳腺癌患者中位PFS和OS分别为17.2个月(14.1～20.3个月)和25.1个月(13.7～36.6个月),HER-2阳性乳腺癌患者中位PFS和OS分别为15.6个月(12.9～51.2个月)和35.8个月(19.8～71.8个月),三阴性乳腺癌患者中位PFS和OS分别为8.6个月(4.6～12.5个月)和18.5个月(5.8～43.5个月)。4种恶性肿瘤相比,患者中位PFS和OS的差异均有统计学意义(PFS：χ²＝16.645,P＝0.001;OS：χ²＝8.617,P＝0.035)。(2)仅有T₄局部病灶者(25例)与T₄病灶伴远处转移者(21例)相比,中位PFS和OS的差异均无统计学意义[PFS：17.2个月(7.3～27.0个月)比9.8个月(8.6～11.1个月),χ²＝ 1.369,P＝0.242;OS：28.5个月(14.1～42.9个月)比20.2个月(14.4～25.9个月), χ²＝1.779,P＝0.182]。(3)皮肤切缘阴性者(35例)中位PFS和OS分别为22.1个月(10.8～33.4个月)和22.2个月(11.3～33.2个月),明显优于皮肤切缘阳性者(11例)的5.1个月(3.0～7.2个月)和10.2个月(5.4～15.0个月)(PFS：χ²＝17.794,P<0.001;OS：χ²＝6.192,P＝0.013)。(4)系统治疗反应好的乳腺癌患者,其中位PFS和OS明显优于治疗反应差的患者[PFS：23.1个月(5.9～40.4个月)比8.7个月(7.8～9.8个月),χ²＝ 9.868,P＝0.001; OS：46.7个月(25.5～68.0个月)比14.3个月(9.9～18.9个月),χ²＝8.994,P＝0.002]。将以上因素纳入多因素Cox比例风险回归模型分析后发现,这些因素都不是影响患者PFS和OS的独立预后因素。 结论乳房巨大恶性肿瘤患者的预后与肿瘤病理类型、切缘是否阴性、全身系统治疗的反应性等多个因素相关,并非由单一因素所决定。     

胸腺神经内分泌肿瘤生存及预后因素分析

目的 探讨胸腺神经内分泌肿瘤(NETTs)的临床病理特征及生存预后影响因素。方法 选取2011年9月至2021年10月在郑州大学第一附属医院经穿刺或手术病理诊断为NETTs的患者69例,回顾性分析其临床病理特征及对预后的影响。结果 入组69例患者主要为男性(78.3%),中位年龄为53岁,中位总生存期(OS)为49.5个月,病灶直径中位值为6.85 cm,最常见的首发症状是胸部不适(42.1%)。单变量分析显示,Ki-67指数(χ²=15.817,P<0.001)、病理分级(χ²=18.440,P<0.001)、病理分期(χ²=8.666,P=0.004)和是否手术(χ²=6.026,P=0.014)与患者OS有关。多变量分析显示,病理分级是OS的独立危险因素(HR=7.133,95%CI:2.183～23.306,P=0.001)。手术是疾病无进展生存期(PFS)的影响因素(P=0.009)。结论 NETTs是罕见恶性肿瘤,手术可以改善患者PFS,低病理分级是预后不良的独立危险因素。     

205例颅内原发弥漫大B细胞淋巴瘤的治疗和预后分析北大核心CSCD

目的分析颅内原发弥漫大B细胞淋巴瘤(DLBCL)病例的疗效和预后影响因素。方法回顾性分析2001年3月到2020年9月于中山大学肿瘤防治中心经病理确诊为颅内原发弥漫大B细胞淋巴瘤患者205例,其中男性101例,女性104例,中位年龄54岁。非生发中心(GCB)型占74.1%(126/170)。177例接受含大剂量氨甲蝶呤(HD-MTX)的诱导化疗,91例接受利妥昔单抗治疗。诱导化疗后完全缓解(CR)59例(30.4%),部分缓解(PR)或疾病稳定(SD)112例(57.7%)。83例接受化疗后巩固性或挽救性放疗,仅14例接受自体干细胞移植(ASCT)。分析病理类型、化疗、利妥昔单抗、放疗及放疗模式、ASCT等影响因素对患者总生存(OS)和无进展生存(PFS)的影响。Kaplan-Meier法计算生存率,log-rank检验进行单因素预后分析,COX模型进行多因素预后分析。结果中位随访34个月,全组5年总生存(OS)和无进展生存(PFS)率分别为55.6%和44.2%。GCB亚型、含HD-MTX化疗、接受利妥昔单抗治疗、诱导化疗后缓解情况、接受放疗是OS或PFS的有利预后因素,其中后三项还是独立预后因素。诱导化疗后,CR患者的巩固放疗未改善生存,PR/SD患者的挽救放疗则显著改善OS和PFS(P值均<0.01)。化疗后巩固ASCT对比巩固放疗生存差异无统计学意义。结论颅内原发DLBCL的非GCB亚型与预后不良有关,含HD-MTX诱导化疗结合利妥昔单抗可进一步改善生存。放射治疗仍是重要治疗手段,而ASCT的实际应用并不充分。

新药诱导后自体干细胞移植巩固治疗对不同危险度骨髓瘤患者的作用探讨*

目的:探讨自体造血干细胞移植（autologous hematopoietic stem cell transplantation ,ASCT）作为新药诱导后的巩固治疗对不同危险分层骨髓瘤患者的无进展生存时间（progression-freesurvival ,PFS）及总生存时间（over all survival,OS）的影响。方法:回顾性分析2006年8 月至2011年7 月在本科行自体干细胞移植巩固治疗的67例多发性骨髓瘤患者,根据ISS 分期及FISH检测结果为基础的最新IMWG 预后标准分为高危组17例,中危组24例,低危组26例。另选取同时期67例接受化疗作为巩固治疗的骨髓瘤患者进行年龄、危险分层配对,比较移植组与化疗组的PFS 和OS差异。所有患者前期均接受硼替佐米和/或沙利度胺为主的诱导治疗。结果:所有患者诱导治疗后均达到部分缓解（partial remissive disease ,PR）以上疗效,移植组与化疗组vs . 接近完全缓解率（nCR/CR）差异无统计学意义（44.8% vs. 37.3% ,P=0.380）。 巩固治疗后,高、中、低危移植组患者中位nCR/CR率分别由47.1% ,37.5% ,50.0% 增加为62.9% ,62.5% ,61.5% 。高危患者移植巩固后中位PFS（30.5 个月vs. 11.2 月,P<0.001）和OS（85.5 vs. 34个月,P=0.015）均明显延长;中危移植组和化疗组中位PFS 和OS无统计学差异（P>0.05）;低危移植组患者与化疗组相比,中位PFS 延长（34.8 vs. 17.6 个月,P=0.012）,OS差异无统计学意义（P>0.05）。 结论:在硼替佐米和/或沙利度胺为基础的新药诱导治疗后,高危骨髓瘤患者更能从自体造血干细胞移植巩固治疗中获益,进而延长生存。      

42例原发性中枢神经系统淋巴瘤患者预后影响因素分析

背景与目的：原发性中枢神经系统淋巴瘤（primary central nervous system lymphoma,PCNSL）是发生在脑、脊髓、脑膜或眼的罕见侵袭型非霍奇金淋巴瘤,无CNS之外的部位累及。PCNSL与其他类型淋巴瘤相比,患者生存期短,预后差,且复发率高,未经治疗的患者的中位生存期仅为3个月。近年来研究发现C-MYC、BCL-2、BCL-6、Ki-67等指标在一定程度上影响PCNSL患者预后。因此,通过分析PCNSL相关蛋白表达、治疗方式及其他临床因素对患者预后的影响, 希望为该病的临床治疗及预后评价进一步积累资料。方法：回顾性分析自2013年6月—2021年5月于大连医科大学附属第二医院治疗的42例经病理学检查明确诊断为原发性中枢神经系统弥漫大B细胞淋巴瘤患者的临床资料,包括性别、年龄、病灶数量、美国东部肿瘤协作组（Eastern Cooperative Oncology Group,ECOG）评分、血清乳酸脱氢酶（lactate dehydrogenase,LDH）、病灶是否累及深部脑组织、治疗方案、病理学Hans分型及C-MYC、BCL-2、BCL-6、Ki-67等生物标志物,结合随访调查,了解患者生存时间及生存状况,应用Kaplan-Meier法及log-rank检验分析影响患者无进展生存期（progression-free survival,PFS）和总生存期（overall survival,OS）的预后相关因素,多因素分析采用COX回归模型。结果：42例PCNSL患者中位发病年龄61岁,男女比例为1.33∶1.00,颅脑增强MRI病灶多呈均匀明显强化。所有患者均接受含有大剂量甲氨蝶呤（high-dose methotrexate,HD-MTX）方案化疗,治疗后评价完全缓解（complete response,CR）20例、部分缓解（partial response,PR）5例,疾病稳定（stable disease,SD）11例,疾病进展（progressive disease,PD）6例。中位PFS为21个月,中位OS为34个月,1年PFS率为63.7%,2年PFS率为47.0%;1年OS率为70.8%,2年OS率为55.6%。单因素分析结果显示,影响PFS的因素是HD-MTX多药联合化疗、鞘内化疗及联合利妥昔单抗。影响OS的因素是ECOG评分≥2、C-MYC（+）、BCL-2及C-MYC双表达、HD-MTX多药联合化疗、鞘内化疗及联合利妥昔单抗。多因素分析结果显示：利妥昔单抗治疗是影响PFS的独立预后因素（P=0.020）,ECOG评分、利妥昔单抗是影响OS的独立预后因素（P=0.007;P=0.046）。与未接受巩固治疗的患者相比,接受巩固治疗患者的中位PFS及OS较高;进一步的亚组分析显示,自体干细胞移植（autologous stem cell transplantation,ASCT）组的中位PFS及OS较全脑放疗（whole brain radiation therapy,WBRT）组高,但差异无统计学意义。结论：PCNSL多发于中老年人,男性多于女性,影像学缺乏特异性。ECOG评分≥2与PCNSL患者较差的OS相关。C-MYC（+）、BCL-2及C-MYC双表达可作为指导危险分层的预后标志物。以HD-MTX为基础的多药联合化疗已经成为PCNSL的首选治疗手段,利妥昔单抗的应用可延长生存期。在全身化疗的基础上,联合局部鞘内化疗可以改善预后。进一步的巩固治疗主要包括ASCT及WBRT,可延长PFS及OS,ASCT可以取得与WBRT相似的疗效,且可避免WBRT的晚期神经毒性,但本研究中因样本量及随访时间的限制,未得出明确的统计学结果。     

Intensive chemotherapy and autologous stem-cell transplantation plus rituximab is superior to conventional chemotherapy for newly diagnosed advanced stage mantle-cell lymphoma: a matched pair analysis.

BACKGROUND: The outcome of 20 patients with newly diagnosed mantle-cell lymphoma (MCL) treated on a prospective trial of autologous stem-cell transplantation (ASCT) and rituximab immunotherapy was compared with the outcome of 40 matched historical control patients treated with standard combination chemotherapy. PATIENTS AND METHODS: Control patients with MCL were identified from a lymphoma database, and pairs were matched with patients receiving ASCT-rituximab for stage of disease, gender and age (+/-5 years). Only patients treated with an anthracycline- or cyclophosphamide-fludarabine-based regimen were included. RESULTS: Seventeen of 20 patients who received ASCT-rituximab remain alive in remission at a median of 30 months from diagnosis; one patient relapsed 2 years post-ASCT, and two died at 7 and 11 months post-ASCT without evidence of lymphoma. Of 40 patients treated with conventional chemotherapy, with a median follow-up of 80 months, 33 have relapsed or progressed and 29 have died. Overall (OS) and progression-free (PFS) survival were superior in patients treated with ASCT-rituximab compared with those treated with conventional chemotherapy (PFS at 3 years, 89% versus 29%, P <0.00001; OS at 3 years, 88% versus 65%, P = 0.052). CONCLUSIONS: This matched-pair analysis suggests that patients with advanced-stage MCL treated with ASCT-rituximab had statistically significantly better PFS and a trend toward better OS than patients treated with conventional chemotherapy. Longer follow-up will determine response duration and the true impact of this treatment strategy on PFS and OS.

Limited-stage mantle-cell lymphoma.

BACKGROUND: Mantle-cell lymphoma (MCL) is known to have a poor outcome, however, most patients present with advanced-stage disease. Little information is available on limited-stage MCL. PATIENTS AND METHODS: We retrospectively reviewed clinicopathological information on all patients with limited-stage MCL seen at the British Columbia Cancer Agency since 1984. RESULTS: Twenty-six patients had low bulk (<10 cm) stage IA (12 patients) or IIA (14 patients) MCL. Initial therapy was involved-field radiation therapy (RT) with or without chemotherapy (CT), 17 patients; CT alone or observation, nine patients. Fifteen patients are alive at a median follow-up of 72 months (range 14-194). Progression-free survival (PFS) at 2 and 5 years was 65% and 46%, and overall survival (OS) 86% and 70%, respectively. Five patients surviving beyond 8 years. Only age and initial use of RT significantly affected PFS. Five-year PFS for patients <60 years of age was 83%, compared with 39% for those aged >/= 60 years, P = 0.04. Patients receiving RT with or without CT (n = 17), had a 5-year PFS of 68%, compared with 11% for those not receiving RT (n = 9, P = 0.002). Receiving RT eliminated the impact of age on PFS (with RT the 5-year PFS was 83% for those aged <60 years and 57% for those >/= 60 years, P = 0.17). Although OS for the whole group was 53% at 6 years, it was 71% for those initially treated with RT, but only 25% for those not given RT (P = 0.13). CONCLUSION: In our experience, patients with limited-stage MCL had an improved PFS when treated with regimens including RT, with a trend towards improved OS. These results suggest a potentially important role for RT in limited-stage MCL.     

High-dose chemotherapy followed by autologous stem cell transplantation for relapsed or refractory Hodgkin lymphoma: prognostic features and outcomes

Between January 1990 and April 2001, 115 patients received high-dose chemotherapy (HDT) followed by autologous stem cell transplantation (ASCT) for relapsed or refractory Hodgkin lymphoma (HL). With a median follow-up of 58 months (range, 1 - 175 months), 5-year progression-free survival (PFS) and overall survival (OS) were 46% and 58%, respectively. Twelve patients with primary refractory disease had a 5-year PFS of 41% and OS of 58%, not significantly different from those of the remaining cohort. Early and overall regimen related mortality were 7% and 16%, respectively. Male gender (P = 0.04) and a time to relapse (TTR) < 12 months (P = 0.03) were associated with decreased OS by univariate analysis. In multivariate analysis, TTR < 12 months remained statistically significant (P = 0.04). We have confirmed that HDT and ASCT result in long-term survival for a proportion of patients with relapsed or refractory HL. All patients, including those with primary refractory disease, benefited from HDT and ASCT.     

The clinical features, therapeutic responses, and prognosis of the patients with mantle cell lymphoma

Mantle cell lymphoma(MCL), a special type of non-Hodgkin’s lymphoma, is incurable through conventional treatment. This study aimed to analyze the clinical features, therapeutic responses, and prognosis of patients with MCL. Clinical data of 30 patients with MCL treated in our hospital between April 2006 and July 2011 were analyzed. Eighteen patients were treated with CHOP plus rituximab (R-CHOP) regimen, 12 underwent conventional chemotherapy. The median age of the 30 patients was 58 years, 23 were men, all patients had Cyclin D1 overexpression, 29 (96.7%) had advanced disease, 11 (36.7%) had bone marrow involvement, 9 (30.0%) had gastrointestinal involvement, and 15 (50.0%) had splenomegaly. The complete response(CR) rate and overall response rate(ORR) were significantly higher in patients undergoing R-CHOP immunochemotherapy than in those undergoing conventional chemotherapy (38.9% vs. 16.7%, P = 0.187; 72.2% vs. 41.4%, P = 0.098). The difference of 2-year overall survival rate between the two groups was not significant (P = 0.807) due to the short follow-up time. The 2-year progression-free survival (PFS) rate was higher in R-CHOP group than in conventional chemotherapy group (53% vs. 25%, P = 0.083), and was higher in patients with a lower mantle cell lymphoma international prognostic index (MIPI) (51% for MIPI 0-3, 33% for MIPI 4-5, and 0% for MIPI 6-11, P = 0.059). Most patients with MCL were elderly; in an advanced stage; showed a male predominance; and usually had bone marrow involvement, gastrointestinal involvement, or splenomegaly. R-CHOP regimen could improve the CR rate and ORR of MCL patients. MIPI can be a new prognostic index for predicting the prognosis of advanced MCL.     

High-dose therapy and autologous stem-cell transplantation for adult patients with Hodgkin's disease who do not enter remission after induction chemotherapy: results in 175 patients reported to the European Group for Blood and Marrow Transplantation. Lymphoma Working Party.

PURPOSE: To investigate the results of high-dose therapy and autologous stem-cell transplantation (ASCT) in adults with Hodgkin's disease who do not enter remission after induction therapy, to determine overall survival (OS) and progression free survival (PFS), and to identify prognostic factors. PATIENTS AND METHODS: A retrospective analysis of 175 patients reported to the European Group for Blood and Marrow Transplantation between November 1979 and October 1995. One hundred were male and 75 were female, with a median age of 26.5 years. Responses to first-line therapy were defined as progressive disease (PD) in 88 and stable/minimally responsive disease (SD/MR) in 87. Seventy-five patients received ASCT after failure of one induction regimen. Second-line therapy was given to the remaining 100 patients. Response to second-line therapy was PD in 34 and SD/MR in 66. OS and PFS rates were determined, and prognostic factors were investigated using univariate and multivariate analyses. RESULTS: Responses to high-dose therapy and ASCT were complete response (30%), partial response (28%), no response (14%), PD (14%), and toxic death (14%). Actuarial 5-year OS and PFS rates were 36% and 32%, respectively. In univariate analysis for PFS and OS, adverse factors were use of a second-line chemotherapy regimen and interval of more than 18 months between diagnosis and ASCT. In multivariate analysis, the interval between diagnosis and ASCT maintained prognostic significance for OS. Response to the chemotherapy regimen given immediately before ASCT had no predictive value. CONCLUSION: High-dose therapy and ASCT is an effective treatment strategy for patients with Hodgkin's disease for whom induction chemotherapy fails. Outcome was equivalent for those with obvious PD or SD/MR in response to the regimen given immediately before high-dose therapy. Prospective randomized studies are required to compare this approach with conventional-dose salvage therapy.
