Efficacy of First-line Chemotherapy Affects the Second-Line Setting Response in Patients with Advanced Non-Small Cell Lung Cancer

Background: Chemotherapy is the mainstay of treatment for the majority of patients with advanced nonsmall cell lung cancer (NSCLC) without driver mutations and many receive therapies beyond first-line. Secondline chemotherapy has been disappointing both in terms of response rate and survival and we know relatively little about the prognostic factors. Materials and Methods: One thousand and eight patients with advanced NSCLC who received second-line chemotherapy after progression were reviewed in Shanghai PulmonaryHospital, China, from September 2005 to July 2010. We analyzed the effects of potential prognostic factors on the outcomes of second-line chemotherapy (overall response rate, ORR; progression free survival, PFS; overall survival, OS). Results: The response and progression free survival of first-line chemotherapy affects the ORR, PFS and OS of second-line chemotherapy (ORR: CR/PR 15.4%, SD 10.1%, PD2.3%, p<0.001; PFS: CR/PR 3.80 months, SD 2.77 months, PD 2.03 months, p<0.001; OS: CR/PR 11.60 months, SD 10.33 months, PD 6.57 months, p=0.578, p<0.001, p<0.001, respectively). On multivariate analysis, better response to first-line therapy (CR/PR: HR=0.751, p=0.002; SD: HR=0.781, p=0.021) and progression within 3-6 months (HR=0.626, p<0.001), together with adenocarcinoma (HR=0.815, p=0.017), without liver metastasis (HR=0.541, p=0.001), never-smoker(HR=0.772, p=0.001), and ECOG PS 0-1 (HR=0.745, p=0.021) were predictors for good OS following secondline chemotherapy. Conclusions: Patients who responded to first-line chemotherapy had a better outcome after second-line therapy for advanced NSCLC, and the efficacy of first-line chemotherapy, period of progression, histology, liver metastasis, smoking status and ECOG PS were independent prognostic factors for OS.     

Mid- and post-ABVD gallium scanning predicts for recurrence in early-stage Hodgkin's disease

PURPOSE: To determine the efficacy of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for patients with Hodgkin's disease and to identify predictors of outcome with this regimen. METHODS: Between 1987 and 1998, 175 patients with Stage I-IV Hodgkin's disease received ABVD as part of initial treatment. Overall survival (OS), freedom-from-treatment-failure (FFTF), and progression-free survival (PFS) were calculated using the Kaplan-Meier technique. Log-rank tests were used to identify univariate predictors of OS, FFTF, and PFS. Specifically, restaging gallium scan results and clinical response after chemotherapy were separately evaluated. RESULTS: The median follow-up time was 64 months. The 5-year OS, FFTF, and PFS rates were 90%, 85%, and 82%, respectively. For Stage I-II patients, restaging gallium scan results and clinical response after chemotherapy were highly predictive of OS, FFTF, and PFS (p < 0.0001). Other significant predictors for higher OS included age <50 (p = 0.002), female gender (p = 0.047), and absence of B symptoms (p = 0.043). Of the 20 patients with a positive restaging gallium scan, 4 received high-dose therapy and 16 continued with conventional-dose therapy or received no further treatment. Of these 16 patients, 11 (69%) were disease-free at last follow-up. CONCLUSIONS: Although a positive mid- or postchemotherapy gallium scan was an adverse prognostic factor for OS, FFTF, and PFS, continued treatment with conventional-dose therapy may be adequate in selected patients with positive scans.     

含利妥昔单抗化疗方案治疗套细胞淋巴瘤效果分析

目的探讨含利妥昔单抗化疗方案治疗套细胞淋巴瘤(MCL)患者效果及预后影响因素。方法回顾性分析2007年6月至2018年11月苏州大学附属第一医院血液科收治的56例≤65岁MCL患者临床资料,化疗方案中均包括利妥昔单抗,观察临床特征、治疗方案及生物学指标对总生存(OS)和无进展生存(PFS)的影响。结果56例患者中位发病年龄57岁,男性43例,女性13例。24例接受R-CHOP方案化疗;29例接受含阿糖胞苷方案化疗,其中15例接受R-hyper CVAD/R-MA方案化疗,14例接受R-CHOP/R-DAHP交替治疗;3例接受其他方案化疗。19例接受自体造血干细胞移植(ASCT)巩固治疗。56例患者中位OS时间74个月,2年OS率83.8%,3年OS率70.9%,2年PFS率72.0%,3年PFS率49.7%。国际预后指数(IPI)评分和治疗中是否接受ASCT是MCL患者OS和PFS的独立影响因素。含阿糖胞苷治疗组总有效率(ORR)93.1%,优于R-CHOP方案组(83.3%),差异无统计学意义(χ²=0.465,P=0.495);两组间OS及PFS差异均无统计学意义(OS:χ²=0.291,P=0.590;PFS:χ²=0.912,P=0.339)。诱导化疗达缓解的MCL患者中,ASCT巩固治疗可延长中位OS时间(72个月比124个月,χ²=3.973,P=0.040)及中位PFS时间(34个月比90个月,χ²=3.984,P=0.046)。简化MCL国际预后指数(sMIPI)评分中高危组患者中接受ASCT巩固治疗患者OS和PFS优于未接受ASCT治疗者(OS:χ²=5.037,P=0.025;PFS:χ²=6.787,P=0.009),而sMIPI评分低危组患者中,是否接受ASCT组间OS、PFS差异均无统计学意义(均P>0.05)。结论含阿糖胞苷的化疗方案对改善MCL患者的预后和生存并不理想。对于诱导化疗达缓解及sMIPI评分中高危组的MCL患者,ASCT巩固治疗可改善其预后,可作为年轻患者的一线巩固治疗方案。     

Autologous stem cell transplantation for patients with active Hodgkin's lymphoma: long-term outcome of 61 patients from a single institution

Sixty-one patients with refractory or relapsed Hodgkin's lymphoma (HL) underwent high-dose chemotherapy and autologous stem cell transplantation (ASCT). All patients had active HL at the time of ASCT: 13 patients had partial remission, 14 refractory disease, 18 sensitive relapse, 4 resistant relapse, and 12 nontreated relapse. Overall transplant-related mortality (TRM) was 16.4% at 1 year. Twenty-eight patients (46%) achieved complete remission (CR). Actuarial 5-year overall survival (OS) and progression-free survival (PFS) were 51% and 47%, respectively. Patients with positive gallium-67 scintigraphy at 3 - 6 months after transplantation had a worse PFS at 5 years (28%) than those with negative 67Ga scan (80%) (p = 0.016), whereas no statistical differences were observed between patients with residual mass and those in CR according to computed tomography scan. In multivariate analysis, bulky disease at diagnosis, bone marrow stem cells, and stage IV at transplant were the only adverse prognostic factors significantly influencing OS. Bulky disease at diagnosis and stage IV at transplant adversely influenced PFS. Although long-term outcome of patients with active HL at the time of ASCT is poor due to a high TRM and a low CR after transplantation, a subgroup of patients with no adverse prognostic factors at ASCT gain benefit from this treatment.     

Outcome and prognostic factors in advanced Hodgkin's disease treated with high-dose chemotherapy and autologous stem cell transplantation: a study of 341 patients.

BACKGROUND: The reported probability of survival of patients with Hodgkin's disease (HD) following high-dose chemotherapy with autologous stem cell transplantation (HDC/ASCT) is 35-65% at 5 years. The Polish Lymphoma Research Group investigated retrospectively prognostic factors for overall survival (OS) and event-free survival (EFS), and the risk of secondary malignancies in a large series of patients who underwent HDC/ASCT. PATIENTS AND METHODS: The data of 341 consecutive patients treated in 10 centers from 1990 to 2002 were collected and analyzed. RESULTS: The actuarial 5-year OS and EFS were 64% [95% confidence interval (CI) 57% to 71%] and 45% (95% CI 39% to 51%), respectively. In the multivariate model, unfavorable prognostic factors for EFS were less than partial response at the time of ASCT [relative risk (RR), 2.92 (95% CI 1.68-5.08); P<0.001] and three or more previous chemotherapy lines (RR, 2.16; 95% CI 1.42-3.30; P<0.001). These two factors were also associated with unfavorable OS (RR, 3.32; 95% CI 1.90-5.79; P<0.001 and RR, 2.34, 95% CI 1.51-3.64; P<0.001). Five-year cumulative risk of secondary malignancy was 8.4% (95% CI 2% to 13%) and the only identified risk factor was splenectomy (P=0.02). CONCLUSIONS: HDC/ASCT should be considered early in the course of disease for patients with a response after standard therapy.     

Impact of Response to Prior Chemotherapy in Patients With Advanced Urothelial Carcinoma Receiving Second-Line Therapy: Implications for Trial Design

BackgroundThe prognostic impact of response to prior chemotherapy independent of performance status (PS), hemoglobin (Hb), liver metastasis (LM), and time from prior chemotherapy (TFPC) in the context of second-line therapy for advanced urothelial carcinoma (UC) is unknown.MethodsSix phase II trials evaluating second-line therapy (n = 504) were pooled. Patients who received prior therapy for metastatic disease were eligible for analysis if Hb, LM, PS, and TFPC were available. Response by Response Evaluation Criteria in Solid Tumors 1.0 to first-line therapy was recorded. Progression-free survival (PFS) and overall survival (OS) were calculated from the date of registration using the Kaplan–Meier method.ResultsA total of 275 patients were evaluable for analysis. Patients received gemcitabine-paclitaxel, cyclophosphamide-paclitaxel, pazopanib, docetaxel plus vandetanib/placebo, or vinflunine (2 trials). Those with prior response (n = 111) had a median OS of 8.0 months (95% confidence interval [CI], 6.8-9.4), compared with 5.9 months (95% CI, 5.0-6.6) for those without prior response (n = 164). Those with prior response had a median PFS of 3.0 months (95% CI, 2.6-4.0) compared with 2.6 months (95% CI, 2.0-2.8) in patients without response. Multivariable analysis did not reveal a significant independent impact of prior response on PFS and OS.ConclusionsBest prior response in patients receiving prior chemotherapy for metastatic disease did not confer an independent prognostic impact with second-line therapy for advanced UC. Given that the setting of prior chemotherapy (metastatic or perioperative) has not appeared significant in a prior study, patients who received prior chemotherapy in perioperative or metastatic settings may be enrolled in the same second-line trial stratified for PS, Hb, LM, and TFPC.     

Efficacy and Safety of Aflibercept in Combination With Chemotherapy Beyond Second-Line Therapy in Metastatic Colorectal Carcinoma Patients: An AGEO Multicenter Study

BackgroundAlthough no data have been reported beyond second-line therapy, aflibercept is approved in this setting in many countries. We conducted a multicenter study to analyze the efficacy and safety of a aflibercept–chemotherapy regimen beyond second-line therapy in patients with metastatic colorectal cancer.Patients and MethodsMetastatic colorectal cancer patients treated with aflibercept beyond second-line therapy were included. Objective response rate, overall survival (OS), and progression-free survival (PFS) were assessed.ResultsA total of 130 patients were included. Median OS and PFS were 7.6 months (95% confidence interval, 6.2-9.3) and 3.3 months (95% confidence interval, 2.7-3.8), respectively. The best response rates were partial response 6.9%, stable disease 38.5%, progressive disease 42.5%, and not evaluable 12%. According to whether patients received previous FOLFIRI (leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin)-bevacizumab or not, OS was 7.7 and 8.1 months (P = .31), and PFS was 2.9 and 3.9 months (P = .02), respectively. Interestingly, PFS and OS were both significantly improved by 4% and 5% per month, respectively, without antiangiogenic treatment before the initiation of the aflibercept regimen. The negative effect of prior FOLFIRI–bevacizumab or shorter time since last bevacizumab was maintained in multivariate analysis for both OS and PFS.ConclusionThe aflibercept–chemotherapy regimen is a therapeutic option in patients with chemorefractory disease beyond second-line therapy, in particular in patients with an antiangiogenic-free interval.     

Comparison of high-dose therapy and autologous stem-cell transplantation with conventional therapy for Hodgkin's disease induction failure: a case-control study. Société Francaise de Greffe de Moelle.

PURPOSE: To determine the prognostic factors and outcome of first-line induction failure Hodgkin's disease patients who were treated with a salvage regimen of high-dose chemotherapy and autologous stem-cell transplantation, and to compare them with matched, conventionally treated patients. PATIENTS AND METHODS: We retrospectively analyzed data relating to 86 Hodgkin's disease patients who underwent autologous stem-cell transplantation after failure of the first chemotherapy regimen, either because they did not enter a complete remission and experienced progression of disease less than 3 months after the end of their first-line treatment or because they showed evidence of disease progression during first-line therapy. Graft patients were matched with 258 conventionally treated patients (three controls per case) for age, sex, clinical stage, B symptoms, and time at risk; patient data were obtained from international databases. RESULTS: Among the 86 graft patients, the median age at diagnosis was 29 years (range, 14 to 57 years). Thirty-nine percent of patients had stage II disease, 23% had stage III disease, and 38% had stage IV disease. Seventy percent of the patients received chemotherapy and 30% received combined modality therapy; 60% of the patients received a seven- or eight-drug regimen. After this first-line treatment, 91% had disease progression and 9% had a brief partial response. Eighty patients received a second-line treatment; pretransplantation status was as follows: 24% of patients had a complete remission, 38% had a partial remission (PR), 14% had stable disease, and disease progression occurred in 24%. With a median follow-up of 22 months (range, 4 to 105 months) from diagnosis, the 5-year event-free survival and overall survival rates from transplantation were 25% and 35% (95% confidence intervals, 15 to 36 and 23 to 49), respectively. In multivariate analysis, the pretransplantation disease status after salvage therapy was the only significant prognostic factor for survival (PR: relative risk = 2.8, P = .017; progressive disease: relative risk (RR) = 5.26, P < .001). From diagnosis, the 6-year overall survival rates of the graft patients and 258 matched conventionally treated patients were 38% and 29%, respectively (P = .058). CONCLUSION: Autologous stem-cell transplantation represents the best therapeutic option currently available for patients with primary induction failure and is associated with acceptable toxicity. Response to second-line treatment before high-dose chemotherapy is the only prognostic factor that can be correlated with survival.     

Pretransplant positive positron emission tomography/gallium scans predict poor outcome in patients with recurrent/refractory Hodgkin lymphoma

BACKGROUND: The objective was to determine the prognostic value of functional imaging (FI) in predicting outcome of patients with recurrent/refractory Hodgkin lymphoma (HL) before undergoing high-dose chemotherapy with autologous stem cell transplantation (ASCT). METHODS: Clinical and imaging data were retrospectively reviewed in 211 consecutive patients treated with ASCT from February 1993 to May 2004. The FI results were correlated with progression-free survival (PFS) and overall survival (OS) using Kaplan-Meier survival analysis. RESULTS: Responses were assessed by conventional criteria and evaluated by positron emission tomography (PET) (n = 68) and gallium scans (n = 144) before ASCT. A complete response (CR) or unconfirmed CR (CRu) was seen in 51% of patients, a partial response (PR) in 41% of patients, and stable or progressive disease in 7% of patients. FI was positive in only 6 of 110 (5%) of CR/CRu patients, in 48 of 86 (56%) of PR patients, and in all 3 patients with progressive disease. The 3-year PFS was 69% for patients with negative FI versus 23% for patients with positive FI (P < .0001). The 3-year OS rates were 87% and 58%, respectively (P < .0001). The 3-year PFS for patients in PR with negative FI was 51% comparable to patients in CR (76%) versus 27% for patients in PR with positive FI (P < .0001). In a multivariate model, positive FI was found to be independently prognostic of PFS. CONCLUSIONS: Pretransplant FI status predicts outcome in patients with recurrent/refractory HL. Positive FI confers a poor prognosis, independent of other traditional presalvage prognostic factors.     

High dose sequential chemotherapy and autologous stem cell transplantation in patients with relapsed/refractory lymphoma

Although high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has become the standard approach for patients with relapsed/refractory Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL), more than 50% of patients will experience relapse following ASCT. High-dose sequential chemotherapy (HDSC) can intensify the conventional salvage treatment and improve the outcome of ASCT by maximal debulking of the tumor load with the use of non-cross resistant drugs, each at their maximal tolerated doses. We conducted a phase II study in 40 patients with relapsed/refractory HD (n = 18) and NHL (n = 22) using HDSC followed by ASCT. Only patients sensitive to salvage chemotherapy were eligible for the protocol, consisting of three phases. Phase I consisted of cyclophosphamide (4.5 g/m²) followed by G-CSF and peripheral blood stem cell (PBSC) collection. Phase II consisted of etoposide (2 g/m²). The transplant phase consisted of mitoxantrone (60 mg/m²) and melphalan (180 mg/m²) followed by PBSC infusion. Eleven out of nineteen patients with B-cell lymphoma received rituximab. Prior to HDSC, 45% of the patients were in complete remission (CR) and 55% were in partial remission (PR). After completion of all phases of the protocol, 35 out of 39 evaluable patients achieved CR (90%) and this was durable in 30 (75%) patients with a projected progression-free survival (PFS) rate at 4 years of 71.7%. Treatment-related mortality rate at day +100 was 2.5% (n = 1). At a median follow-up of 32 months (range, 3 - 61), nine patients relapsed/progressed and eleven patients died. The estimated 4-year PFS and overall survival (OS) were 72.2% and 47.6% in HD patients and 70.3% and 69.4% in NHL patients, respectively. Factors predicting OS were response to conventional salvage therapy and stage prior to salvage therapy. When compared to patients achieving PR, patients who attained CR prior to HDSC had a significantly higher probability of 4-year OS (78.4% vs 31.3%, p = 0.02). Three prognostic subgroups were defined according to the score determined by stage prior to initiation of salvage chemotherapy, remission duration prior to salvage (refractory/early relapse vs. late relapse) and response to salvage. Prognostic score was found to predict OS, PFS and event free survival (EFS). In conclusion, HDSC followed by ASCT is an effective salvage therapy with acceptable toxicity, allowing further consolidation of response attained by conventional salvage therapy.     

High-dose therapy and autologous hematopoietic stem-cell transplantation for recurrent or refractory pediatric Hodgkin's disease: results and prognostic indices.

PURPOSE: To evaluate the outcome of pediatric patients with refractory or relapsed Hodgkin's disease (HD) who undergo high-dose therapy and autologous hematopoietic stem-cell transplantation (AHSCT). PATIENTS AND METHODS: From 1989 to 2001, 41 pediatric patients with relapsed or primary refractory HD underwent high-dose therapy followed by AHSCT according to one of four autologous transplantation protocols at Stanford University Medical Center (Stanford, CA). Pretreatment factors were analyzed by univariate and multivariate analysis for prognostic significance for 5-year overall survival (OS), event-free survival (EFS), and progression-free survival (PFS). RESULTS: At a median follow-up of 4.2 years (range, 0.7 to 11.9 years), the 5-year OS, EFS, and PFS rates were 68%, 53%, and 63%, respectively. Multivariate analysis determined the following three factors to be significant predictors of poor OS and EFS: extranodal disease at first relapse, presence of mediastinal mass at time of AHSCT, and primary induction failure. Two of these factors also predicted for poor PFS (extranodal disease at time of first relapse and presence of mediastinal mass at time of transplantation). CONCLUSION: More than half of children with relapsed or refractory HD can be successfully treated with the combination of high-dose therapy and AHSCT, confirming the efficacy of this approach. Further investigation is now required to determine the optimal timing of AHSCT, as well as to develop alternative regimens for those patients with factors prognostic for poor outcome after AHSCT.     

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。     

Autologous Stem-Cell Transplantation for Poor-Risk and Relapsed Intermediate- and High-Grade Non-Hodgkin's Lymphoma

The primary objective of this study was to evaluate the outcome of patients treated with high-dose chemo-/radiotherapy or high-dose chemotherapy and autologous stem-cell transplant (ASCT) for relapsed, refractory, or poor-risk intermediate-grade (IG) and high-grade (HG) non-Hodgkin's lymphoma (NHL). The secondary objectives were to determine prognostic factors for relapse and survival. Between February 1987 and August 1998, 264 patients, 169 (64%) IG and 95 (36%) HG, underwent high-dose therapy and ASCT at City of Hope National Medical Center (COHNMC). There were 157 (59%) males and 107 (41%) females with a median age of 44 years (range, 5–69 years). The median number of prior chemotherapy regimens was 2 (range, 1–4), and 71 (27%) had received prior radiation as part of induction or as salvage therapy. The median time from diagnosis to ASCT was 10.8 months (range, 3–158 months). Ninety-four patients (36%) underwent transplantation in first complete/partial remission (CR/PR), 40 (15%) in induction failure, and 130 (49%) in relapse or subsequent remission. Two preparative regimens were used: total body irradiation/high-dose etoposide/cyclophosphamide (TBI/VP/CY) in 208 patients (79%) and carmustine/etoposide/cyclophosphamide (BCNU/VP/CY) in 56 patients (21%). One hundred sixty-three patients (62%) received peripheral blood stem cells (PBSC) and 101 (38%) received bone marrow (BM) alone or BM plus PBSC. At a median follow-up of 4.43 years for surviving patients (range, 1–12.8 years), the 5-year Kaplan-Meier estimates of probability of overall survival (OS), progression-free survival (PFS), and relapse for all patients are 55% (95% confidence interval [CI]: 49%–61%), 47% (95% CI: 40%–53%), and 47% (95% CI: 40%–54%), respectively. There were 27 deaths (10%) from nonrelapse mortality, including seven (3%) patients who developed second malignancies (five with myelodysplasia/acute myelogenous leukemia and two with solid tumors). By stepwise Cox regression analysis, disease status at ASCT was the only prognostic factor that predicted for both relapse and survival. The 5-year probability of PFS for patients transplanted in first CR/PR was 73% (95% CI: 62%–81%) as compared to 30% (95% CI: 16%– 45%) for induction failure and 34% (95% CI: 26%–42%) for relapsed patients. Our results further support the role of high-dose therapy and ASCT during first CR/PR for patients with poor-risk intermediate- and high-grade NHL. Early transplant is recommended for patients failing initial induction therapy or relapsing after chemotherapy-induced remission. Relapse continues to be the most common cause of treatment failure. An alternative approach to prevent relapse, the incorporation of radioimmunotherapy into the high-dose regimen, is being investigated. The development of a second malignancy is a serious complication of high-dose therapy, which requires close surveillance.

Maintenance biotherapy for metastatic melanoma with interleukin-2 and granulocyte macrophage-colony stimulating factor improves survival for patients responding to induction concurrent biochemotherapy.

PURPOSE: A prospective Phase II study of a novel maintenance biotherapy regimen after induction biochemotherapy was conducted in patients with metastatic melanoma in efforts to maintain responses and improve survival. EXPERIMENTAL DESIGN: Thirty-three patients with poor prognosis metastatic melanoma who achieved a partial response (PR) or stable disease (SD) to induction concurrent biochemotherapy were treated with chronic low-dose interleukin (IL)-2 and granulocyte macrophage-colony stimulating factor, and intermittent pulses of intermediate/high-dose decrescendo IL-2 over a 12-month period. The outcome of these patients was compared with a control group of patients at our institution who were treated recently with induction biochemotherapy and achieved a PR or SD. RESULTS: Five patients (15%) achieved a complete response, and 4 patients (12%) maintained SD for at least 6 months on maintenance biotherapy. The median progression-free survival (PFS) and overall survival (OS) were 8.1 months and 18.5 months, respectively, compared with historical controls, which were PFS 5.9 months (P = 0.0015) and OS 9.3 months (P = 0.0004). Administration of maintenance biotherapy was a significant predictor of PFS (P = 0.0008) and OS (P = 0.0001) in multivariate and matched-pair analyses (P = 0.002). The maintenance biotherapy regimen was well tolerated with no dose-limiting acute or cumulative toxicities. CONCLUSION: In this single institution study, maintenance biotherapy with IL-2 and granulocyte macrophage colony-stimulating factor in patients achieving PR or SD to induction biochemotherapy improved PFS and OS compared with historical controls. A larger multicenter Phase II trial has been initiated in an effort to confirm these results.     

Selection of a patient subgroup with advanced esophageal squamous carcinoma who could benefit from second-line chemotherapy

Despite first-line therapy, most patients with advanced esophageal squamous cell carcinoma (ESCC) experience disease progression and may become eligible for second-line chemotherapy. Although commonly used, the role of salvage chemotherapy in patients with recurrent or metastatic ESCC has not yet been established. We analyzed 53 patients who had received second-line chemotherapy after the failure of cisplatin-based combination chemotherapy with or without radiotherapy as first-line therapy in ESCC between March 2000 and June 2008. Median progression-free survival (PFS) and overall survival (OS) for second-line chemotherapy were 2.4 and 5.2 months, respectively, with an overall response rate of 18.9%. In multivariate analysis, Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 2 or more and PFS under first-line therapy <4 months were independent prognostic factors for decreased OS. OS was estimated based on the number of adverse prognostic factors: 0 = good; 1 = intermediate, and 2 = poor. The median OS for the good, intermediate, and poor prognostic groups were 11.2, 4.5 and 4.3 months, respectively (p < 0.001). The good prognostic group showed better OS than the intermediate or poor groups (p < 0.001). Second-line chemotherapy may be beneficial for OS in ESCC patients with ECOG PS 0-1 and PFS under first-line therapy ≥4 months.

HIGH DOSE CHEMORADIOTHERAPY WITH AUTOLOGOUS HEMATOPOIETIC STEM CELL TRANSPLANTATION IN THE TREATMENT OF ADVANCED HODGKIN''''s LYMPHOMA: A REPORT OF 11 CASES

High dose therapy (HDT) with autologous hematopoietic stem cell transplantation (ASCT) has become one of the standard salvaged treatments for the Hodgkin抯 Lymphoma (HL) patients with relapsed or resistant disease. But its value for the primary treatment of patients with advanced disease and poor prognostic factors remains indefinite. It is being one of the clinic research directions to select this kind of patients to undergo ASCT treatment in recent years. From May, 1994 to December, 2…     

Autologous stem cell transplantation for primary refractory Hodgkin's disease: results and clinical variables affecting outcome.

BACKGROUND: Patients with primary refractory Hodgkin's disease (PR-HD) have a dismal prognosis when treated with conventional salvage chemotherapy. We analyzed time to treatment failure (TTF), overall survival (OS) and clinical variables influencing the outcome in patients undergoing autologous stem cell transplantation (ASCT) for PR-HD and reported to the Grupo Espa?ol de Linfomas/Trasplante Autólogo de Médula Osea (GEL/TAMO). PATIENTS AND METHODS: Sixty-two patients, 41 males and 21 females with a median age of 27 years (range 13-55) were analyzed. Forty-two patients (68%) had advanced stage at diagnosis, 47 (76%) presented with B symptoms and 29 (47%) with a bulky mediastinal mass. Seventy-five percent of the patients had received more than one line of therapy before ASCT. Thirty-three patients received bone marrow as a source of hematopoietic progenitors, and 29 peripheral blood. Six patients were conditioned with high-dose chemotherapy plus total-body irradiation and 56 received chemotherapy-based protocols. RESULTS: One-year transplantation-related mortality was 14% [95% confidence interval (CI) 6% to 23%]. Response rate at 3 months after ASCT was 52% [complete remission in 21 patients (34%), partial remission in 11 patients (18%)]. Actuarial 5-year TTF and OS were 15% (95% CI 5% to 24%) and 26% (95% CI 13% to 39%), respectively. The presence of B symptoms at ASCT was the only adverse prognostic factor significantly influencing TTF [relative risk (RR) 1.75, 95% CI 0.92-3.35, P = 0.08]. The presence of B symptoms at diagnosis (RR 2.08, 95% CI 0.90-4.79, P = 0.08), MOPP-like regimens as first-line therapy (RR 3.84, 95% CI 1.69-9.09, P = 0.001), bulky disease at ASCT (RR 2.79, 95% CI 0.29-6.03, P = 0.009) and two or more lines of therapy before ASCT (RR 2.24, 95% CI 0.95-5.27, P = 0.06) adversely influenced OS. CONCLUSIONS: In our experience, although overall results of ASCT in PR-HD patients are poor, one-quarter of the patients remain alive at 5 years. Despite this, other therapeutic strategies should be investigated in this group of patients to improve the outcome.     

Impact of involved field radiotherapy in partial response after doxorubicin-based chemotherapy for advanced aggressive non-Hodgkin's lymphoma

PURPOSE: Whether salvage therapy in patients with advanced aggressive non-Hodgkin's lymphoma (NHL) in partial remission (PR) should consist of radiotherapy or autologous stem-cell transplantation (ASCT) is debatable. We evaluated the impact of radiotherapy on outcome in PR patients treated in four successive European Organization for Research and Treatment of Cancer trials for aggressive NHL. PATIENTS AND METHODS: Records of 974 patients (1980-1999) were reviewed regarding initial response, final outcome, and type and timing of salvage treatment. After 8 cycles of doxorubicin-based chemotherapy, 227 NHL patients were in PR and treated: 114 received involved field radiotherapy, 16 ASCT, 93 second-line chemotherapy, and 4 were operated. Overall survival (OS) and progression-free survival (PFS) after radiotherapy were estimated (Kaplan-Meier method) and compared with other treatments (log-rank). Impact on survival was evaluated by multivariate analysis (Cox proportional hazards model). RESULTS: The median PFS in PR patients was 4.2 years and 48% remained progression-free at 5 years. Half of the PR patients converted to a complete remission. After conversion, survival was comparable to patients directly in complete remission. Radiotherapy resulted in better OS and PFS compared with other treatments, especially in patients with low to intermediate International Prognostic Index score, bulky disease, or nodal disease only. Correction by multivariate analysis for prognostic factors such as stage, bulky disease, and number of extranodal locations showed that radiotherapy was clearly the most significant factor affecting both OS and PFS. CONCLUSION: This retrospective analysis demonstrates that radiotherapy can be effective for patients in PR after fully dosed chemotherapy; assessment in a randomized trial (radiotherapy vs. ASCT) is justified.
