Intensive salvage therapy with high-dose chemotherapy for patients with advanced Hodgkin's disease in relapse or failure after initial chemotherapy: results of the Groupe d'Etudes des Lymphomes de l'Adulte H89 Trial.

PURPOSE: To evaluate prospectively the feasibility and efficacy of early intensive therapy, including intensified cytoreductive chemotherapy (CT) and high-dose CT (HDCT) followed by autologous stem-cell transplantation (ASCT), in patients with advanced Hodgkin's disease (HD) who failed to respond completely or relapsed after initial treatment. PATIENTS AND METHODS: Among 533 eligible patients with newly diagnosed stage IIIB-IV HD enrolled in the H89 trial, all 157 patients with induction failure (IF) (n = 67), partial response (PR) of less than 75% (n = 22), or relapse (n = 68) were included in this study. Planned salvage therapy included mitoguazone, ifosfamide, vinorelbine, and etoposide monthly for two to three cycles followed by high-dose carmustine, etoposide, cytarabine, and melphalan with ASCT. RESULTS: With a median follow-up of 50 months, the 5-year survival estimates were 30%, 72%, and 76% for the IF, PR, and relapse groups, respectively (P =.0001), 71% for the 101 patients given HDCT, and 32% for the 48 patients treated without HDCT (P =.0001). Multivariate analysis using time-dependent Cox model indicated that B symptoms at progression, salvage without HDCT, and chemoresistant disease before HDCT were significantly associated with shorter overall survival. CONCLUSION: Early intensive therapy improves the outcomes of patients with advanced HD who failed to respond completely to initial treatment and those who relapsed with adverse prognostic factors. However, for patients with IF and chemoresistant disease, this approach remains unsatisfactory.     

BEACOPP and COPP/ABVD as salvage treatment after primary extended field radiation therapy of early stage Hodgkins disease - results of the German Hodgkin Study Group

Patients with early stage favorable Hodgkin's disease who relapse after extended field radiotherapy have satisfactory results. We retrospectively analysed patients with relapsed HD after initial radiation therapy alone to determine treatment outcome and prognostic factors. Nine-hundred and forty five patients in localized stages without risk factors received either 40 Gy extended field RT or 30 Gy EF RT followed by an additional 10 Gy to involved lymph node regions. 107 patients relapsed and received salvage therapy. Characteristics of the 107 patients at relapse were as follows: median age was 34 years (range 18--75) with relapse occuring at a median of 19 months (range 4--98 months), 31% were female. The majority of patients (93%) were treated with conventional chemotherapy. Sixty-nine percent were treated with COPP/ABVD like regimens, 21% with BEACOPP, and 3% received various other regimens. Seven percent were treated with radiotherapy alone. Complete remission was achieved in 87% of all salvaged patients. The median follow-up after relapse was 45 months. FF2F (freedom from second treatment failure) and OS (overall survival) were 81% and 89%, respectively. In multivariate analysis age was the major prognostic factor for FF2F and OS (p<0.0001, for both). Further independent prognostic factors were B symptoms (p=0.05) and salvage chemotherapy (p=0.03) for FF2F, and B symptoms (p=0.03) and extranodal involvement (p=0.02) for OS. The long-term outcome of patients relapsing after EF RT is excellent. Age, B symptoms, extranodal involvement and salvage chemotherapy were identified as prognostic factors for second relapse and survival.     

Risk factors and a prognostic score for survival after autologous stem-cell transplantation for relapsed or refractory Hodgkin lymphoma

BackgroundNovel agents are changing the treatment of relapsed or refractory Hodgkin lymphoma (HL). Nevertheless, high-dose chemotherapy and autologous stem-cell transplantation (ASCT) are considered standard of care in eligible patients. To identify patients who could benefit most from novel therapeutic approaches, we investigated a comprehensive set of risk factors (RFs) for survival after ASCT.MethodsIn this multinational prognostic multivariable modeling study, 23 potential RFs were retrospectively evaluated in HL patients from nine prospective trials with multivariable Cox proportional hazards regression analyses (part I). The resulting prognostic score was then validated in an independent clinical sample (part II).ResultsIn part I, we identified 656 patients treated for relapsed/refractory HL between 1993 and 2013 with a median follow-up of 60 months after ASCT. The majority of potential RFs had significant impact on progression-free survival (PFS) with hazard ratios (HR) ranging from 1.39 to 2.22. The multivariable analysis identified stage IV disease, time to relapse ≤3 months, ECOG performance status ≥1, bulk ≥5 cm and inadequate response to salvage chemotherapy [<partial remission by computed tomography (CT)] as significant and non-redundant RFs for PFS. A risk score composed of these equally weighed RFs was significantly prognostic for PFS (HR = 1.67 for each additional RF; P < 0.0001). Validation in an independent sample of 389 patients treated in different clinical settings with evaluation of response to salvage therapy by functional imaging instead of CT confirmed the excellent discrimination of risk groups and significant prognostication of PFS and overall survival (OS) after ASCT (HR = 1.70 and HR = 1.63, respectively; P < 0.0001).ConclusionsBased on this large study (n = 1045), precise and valid risk prognostication in HL patients undergoing ASCT can be achieved with five easily available clinical RFs. The proposed prognostic score hence allows reliable stratification of patients for innovative therapeutic approaches in clinical practice and future trials.Registered trialsGHSG HD10 NCT00265018, HD11 NCT00264953, HD12 NCT00265031, HD13 ISRCTN63474366, HD14 ISRCTN04761296, HD15 ISRCTN32443041 and HDR2 NCT00025636.     

Salvage radiotherapy in patients with relapsed and refractory Hodgkin's lymphoma: a retrospective analysis from the German Hodgkin Lymphoma Study Group.

PURPOSE: To evaluate treatment outcome and prognostic factors in patients with refractory or first relapsed Hodgkin's disease (HD) treated with salvage radiotherapy (SRT) alone. PATIENTS AND METHODS: From 4,754 patients registered in the database of the German Hodgkin Study Group from 1988 to 1999, 624 patients were identified with progressive disease (n = 202), or with early (n = 170) or late (n = 252) relapsed HD. At first treatment failure, SRT alone was given to 100 patients. Patient characteristics were: median age, 36 years; progressive disease, 47%; early relapse, 23%; late relapse, 30%; and "B" symptoms, 14%. Eighty-five percent of the patients relapsed after cyclophosphamide, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine (COPP/ABVD) -like regimens; 8% after bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) regimens, 7% after first-line radiotherapy alone. RESULTS: The volume irradiated was mantle field in 43% of patients, inverted-Y in 8%, total nodal irradiation in 12%, and involved-field in 37%. The median SRT dose was 40 Gy (range, 15 to 50 Gy). Seventy-seven patients achieved a complete remission and four patients achieved a partial remission. The 5-year freedom from treatment failure and overall survival (OS) rates were 28% and 51%, respectively. In multivariate analysis, significant prognostic factors for OS were B symptoms (P = .018) and stage at relapse (P = .014). For freedom from second failure (FF2F) Karnofsky performance status (P = .0001) was significant. In patients with limited stage at progression/relapse, duration of first remission was significant (P = .04) for FF2F. CONCLUSION: SRT offers an effective treatment for selected subsets of patients with relapsed or refractory HD.     

Treatment of primary progressive Hodgkin's and aggressive non-Hodgkin's lymphoma: is there a chance for cure?

PURPOSE: To determine differences in prognosis between primary progressive Hodgkin's disease (HD) and aggressive non-Hodgkin's lymphoma (NHL), we retrospectively analyzed patients with progressive lymphoma who were treated with different salvage chemotherapy regimens including high-dose chemotherapy (HDCT) followed by autologous stem-cell support (ASCT). PATIENTS AND METHODS: One hundred thirty-one patients with primary progressive lymphoma (HD, n = 67; NHL, n = 64) were enrolled. Primary progressive disease was defined as disease progression during first-line chemotherapy or only transient response (complete or partial response lasting 相似文献   

Salvage Therapy in Hodgkin's Lymphoma

Hodgkin's lymphoma (HL) is a commonly cured malignancy. Unfortunately, patients who are refractory to or relapse after first‐line treatment pose a significant therapeutic challenge. There is evidence that these patients are best treated with an approach involving salvage chemotherapy followed by high‐dose chemotherapy and autologous stem cell transplant (HDCT/ASCT). This approach may result in cure, with better results in patients with low‐risk relapse. In patients with high‐risk relapse and refractory disease, HDCT/ASCT is rarely curative. More aggressive transplant approaches have shown promising results in this group and are currently under active investigation. For those relapsing after HDCT/ASCT, there exists a range of therapeutic options, including further salvage chemotherapy, reduced‐intensity allogeneic transplantation, monoclonal antibody therapy, and novel agents. All patients in this category should be considered for enrollment in clinical trials. This review discusses the evidence behind the current practice in patients with relapsed or refractory HL. Specifically, the efficacy of various salvage chemotherapy regimens, the risk factors influencing outcome with HDCT/ASCT, and the results with alternative transplant approaches, monoclonal antibody therapies, and novel agents are addressed. We conclude by providing our approach to these patients, with the hope that this will serve as a framework for the practicing oncologist.     

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.     

Time-intensified dexamethasone/cisplatin/cytarabine: an effective salvage therapy with low toxicity in patients with relapsed and refractory Hodgkin's disease.

BACKGROUND: An important variable affecting outcome in relapsed and refractory Hodgkin's disease (HD) is the potential of conventional salvage chemotherapy to reduce tumor volume before high-dose chemotherapy (HDCT) and autologous stem cell transplantation. Currently, the optimal salvage chemotherapy regimen for these patients is unclear. Since dexamethasone/cisplatin/cytarabine (DHAP) given at 3-4 week intervals has been shown to be very effective in patients with relapsed aggressive non-Hodgkin's lymphoma, we evaluated this regimen given at a median of 16-day intervals in patients with relapsed and refractory HD. PATIENTS AND METHODS: Patients with relapsed or refractory HD were treated with two cycles of DHAP [dexamethasone 40 mg intravenously (i.v.) day 1-4, cisplatin 100 mg/m(2) i.v. as 24-h continuous infusion day 1, and cytarabine 2 g/m(2) i.v. 12q day 2]. Granulocyte colony-stimulating factor (G-CSF) was given at a dose of 5 micro g/kg from day 4 until day 13. Patients with partial remission (PR) or complete remission (CR) after two cycles of DHAP received sequential HDCT. RESULTS: The median age of the 102 patients included was 34 years (range 21-64 years). Forty-two percent of the patients had late relapse, 29% early relapse, 12% multiple relapse and 16% primary progressive/refractory disease. The response rate (RR) after two cycles of DHAP was 89% (21% CR, 68% PR). The RRs for patients with late, early, multiple and progressive HD were 91%, 93%, 92% and 65%, respectively. Using the chi-square test for independence, remission status (relapsed HD versus progressive HD) and stage at relapse (stage I/II versus stage III/IV) were significant factors for response to DHAP. WHO grade 4 leukocytopenia and thrombocytopenia were the main toxic- ities occurring in 43% (mean duration 1.1 days, range 0-6) and 48% (mean duration 1.4 days, range 0-11) of all courses, respectively. Neither severe infections nor treatment-related deaths occurred. Peripheral blood stem cells (PBSCs) were collected after the first cycle DHAP in eight patients. The hematopoietic progenitors showed a very rapid increase from day 10 with a synchronous and impressive peak on day 12. A mean of 6.1 x 10(6)/kg CD34(+) cells were collected per apheresis. As originally recommended in the protocol, PBSCs were routinely collected during sequential HDCT in the remaining patients. CONCLUSIONS: A brief tumor-reducing program with two cycles of DHAP given in short intervals supported by G-CSF is effective and well-tolerated in patients with relapsed and refractory HD. This regimen can be used to mobilize stem cells and select those patients with chemosensitive relapse who should subsequently be treated with HDCT.     

Stanford V and radiotherapy for locally extensive and advanced Hodgkin's disease: mature results of a prospective clinical trial.

PURPOSE: To provide more mature data on the efficacy and complications of a brief, dose-intense chemotherapy regimen plus radiation therapy (RT) to bulky disease sites for locally extensive and advanced-stage Hodgkin's disease. PATIENTS AND METHODS: One hundred forty-two patients with stage III or IV or locally extensive mediastinal stage I or II Hodgkin's disease received Stanford V chemotherapy for 12 weeks followed by 36-Gy RT to initial sites of bulky (> or =5 cm) or macroscopic splenic disease. Freedom from progression (FFP), overall survival (OS), and freedom from second relapse (FF2R) were determined using life-table estimates. Outcomes were analyzed according to the international prognostic score. Late effects of treatment were recorded in follow-up. RESULTS: With a median follow-up of 5.4 years, the 5-year FFP was 89% and the OS was 96%. No patient progressed during treatment, and there were no treatment-related deaths. FFP was significantly superior among patients with a prognostic score of 0 to 2 compared with those with a score of 3 and higher (94% v 75%, P <.0001). No secondary leukemia was observed. To date, there have been 42 pregnancies after treatment. Among 16 patients who relapsed, the FF2R was 69% at 5 years. CONCLUSION: These data confirm our preliminary report that Stanford V chemotherapy with RT to bulky disease sites is highly effective in locally extensive and advanced Hodgkin's disease. It is most important to compare this approach with standard doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy in the ongoing intergroup trial (E2496) to determine whether Stanford V with or without RT represents a therapeutic advance.     

Second malignancy risk associated with treatment of Hodgkin's lymphoma: meta-analysis of the randomised trials.

BACKGROUND: Despite several investigations, second malignancy risks (SMR) following radiotherapy alone (RT), chemotherapy alone (CT) and combined chemoradiotherapy (CRT) for Hodgkin's lymphoma (HL) remain controversial. PATIENTS AND METHODS: We sought individual patient data from randomised trials comparing RT versus CRT, CT versus CRT, RT versus CT or involved-field (IF) versus extended-field (EF) RT for untreated HL. Overall SMR (including effects of salvage treatment) were compared using Peto's method. RESULTS: Data for between 53% and 69% of patients were obtained for the four comparisons. (i) RT versus CRT (15 trials, 3343 patients): SMR were lower with CRT than with RT as initial treatment (odds ratio (OR) = 0.78, 95% confidence interval (CI) = 0.62-0.98 and P = 0.03). (ii) CT versus CRT (16 trials, 2861 patients): SMR were marginally higher with CRT than with CT as initial treatment (OR = 1.38, CI 1.00-1.89 and P = 0.05). (iii) IF-RT versus EF-RT (19 trials, 3221 patients): no significant difference in SMR (P = 0.28) although more breast cancers occurred with EF-RT (P = 0.04 and OR = 3.25). CONCLUSIONS: Administration of CT in addition to RT as initial therapy for HL decreases overall SMR by reducing relapse and need for salvage therapy. Administration of RT additional to CT marginally increases overall SMR in advanced stages. Breast cancer risk (but not SMR in general) was substantially higher after EF-RT. Caution is needed in applying these findings to current therapies.     

Current status of autologous stem cell transplantation in relapsed and refractory Hodgkin's lymphoma

Despite the relatively high long-term disease-free survival (DFS) rate for patients with Hodgkin lymphoma (HL) with modern combination chemotherapy or combined modality regimens, ～20% of patients die from progressive or relapsed disease. The standard treatment for relapsed and primary refractory HL is salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT), which has shown a 5-year progression-free survival rate of ～50%-60%. Recent developments in a number of diagnostic and therapeutic modalities have begun to improve these results. Functional imaging, refinement of clinical prognostic factors, and development of novel biomarkers have improved the predictive algorithms, allowing better patient selection and timing for ASCT. In addition, these algorithms have begun to identify a group of patients who are candidates for more aggressive treatment beyond standard ASCT. Novel salvage regimens may potentially improve the rate of complete remission prior to ASCT, and the use of maintenance therapy after ASCT has become a subject of current investigation. We present a summary of developments in each of these areas.     

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.     

Prognostic factors for patients relapsing after radiotherapy for early-stage Hodgkin's disease

Prognostic factors were analyzed retrospectively in 109 patients who relapsed after treatment with radiation only for Hodgkin's disease. Factors analyzed included initial stage, age, time to first relapse, histology, sex, extent of initial irradiation, sites of relapse, relapse stage (RS), average relative dose intensity (ARDI) of chemotherapy, and type of salvage therapy. Ninety-three percent of the patients received either standard or modified mechlorethamine, vincristine, procarbazine, and prednisone (MOPP). With a median follow-up of 8.3 years, the actuarial survival and freedom from second relapse (FF2ndR) was 57% at 10 years. The extent of disease at the time of relapse, or so-called RS was found to be the single most important prognostic factor. Nearly 90% of patients with RS IA or IEA (favorable group) were disease free, and nearly 60% of patients with RS IIA, IIEA, or IIIA (intermediate group) were disease free compared with only 34% of patients with B symptoms or stage IV disease (unfavorable group). In a subset analysis, the use of combined modality therapy (CMT) was associated with an improved FF2ndR and survival in patients from the intermediate and unfavorable relapse groups. Age greater than 50 years was associated with an increased risk of second relapse and a lower survival. The other factors analyzed appeared to be of no independent prognostic value.     

Positron emission tomography using 18F-fluorodeoxyglucose for the evaluation of residual Hodgkin's disease mediastinal masses

Given its obvious prognostic implications, the correct interpretation of the significance of any residual mediastinal mass following Hodgkin's disease (HD) treatment keeps maintaining its paramount importance. In this respect, 18F-fluorodeoxyglucose positron emission tomography (PET) is proving very effective for both active disease detection and relapse prediction. Twenty-nine consecutive HD patients, in whom computed tomography (CT) scan performed after therapy completion had documented a residual mediatinal mass of at least 2 cm, prospectively entered the study and underwent PET within 1 week from CT scan. With a median follow-up of 28 months from PET execution, no relapse was recorded among the 17 patients presenting with a negative PET. On the contrary, 9 of the 12 patients presenting with a positive PET relapsed/progressed within one year from PET execution. PET's negative and positive predictive values at 1 year were 100% and 75%, respectively. A negative PET seems to possibly exclude relapse in HD patient with a residual mediastinal mass. On the contrary, a positive PET result indicates a significantly higher risk of relapse. However, due to possible false positive results, a closer follow-up for all and a pathologic study in few selected patients is warranted.     

Thoracic radiation therapy before autologous bone marrow transplantation in relapsed or refractory Hodgkin's disease. PMH Lymphoma Group, and the Toronto Autologous BMT Group

The aim of this study was to assess the relationship between radiation therapy (RT) and treatment-related mortality in patients receiving high-dose chemotherapy (HDCT) and autologous bone marrow transplantation (ABMT) for recurrent/refractory Hodgkin's disease (HD). Between December 1986 and December 1992, 59 patients previously treated at the Princess Margaret Hospital underwent HDCT (etoposide 60 mg/kg, melphalan 160 mg/m2) and ABMT, performed for refractory (13 patients) or relapsed (46 patients) HD. RT was incorporated in the salvage treatment with the intent to achieve complete control of disease prior to ABMT. RT was given before ABMT in 33 patients, and after ABMT in 4 patients. Treatment-related (TR) mortality was defined as any death occurring within 100 days of ABMT. Autopsies were performed for all patients with TR deaths. With a median follow-up of 4.6 years (range 1.2-7.4 years), the actuarial overall survival was 41% +/- 14% at 5 years. We observed 37 deaths, and 10 of these were TR deaths. Among the 24 patients who received thoracic RT before ABMT, there were 8 TR deaths, 3 of these solely attributable to radiation pneumonitis. The remaining 5 TR deaths all had respiratory failure with complicating sepsis as a major medical problem. The interval from RT to ABMT was shorter for 8 patients dying of TR death (mean 37 days; range 0-103 days), than for the 16 survivors (mean 105 days; range 0-263 days) (P = 0.026). Among 9 patients with ABMT within 50 days of thoracic RT, 6 had TR death. In contrast, among the 35 patients without thoracic RT (26 no RT, 9 non-thoracic RT), there were only 2 TR deaths. The 4 patients treated with mantle RT post-ABMT had no serious pulmonary complications. The use of thoracic RT before HDCT and ABMT was associated with a high post-transplant mortality rate. It was most evident in patients who received thoracic RT within 50 days prior to ABMT, or when the target volume included large volume of lung. We recommend that the use of post-transplant RT be investigated to decrease TR mortality.     

Non-Hodgkin's lymphoma after primary Hodgkin's disease in the German Hodgkin's Lymphoma Study Group: incidence, treatment, and prognosis.

PURPOSE: The cumulative incidence for non-Hodgkin lymphoma's (NHL) after primary Hodgkin's disease (HD) ranges between 1% and 6%. To investigate the course of disease for secondary NHL, we retrospectively analyzed patients treated within clinical trials of the German Hodgkin's Lymphoma Study Group (GHSG) since 1981. PATIENTS AND METHODS: From 1981 to 1998, the GHSG conducted three generations of clinical trials for the treatment of primary HD involving a total of 5,406 patients. Reference histology by an expert panel was obtained for 4,104 of the patients. Data on incidence, treatment, and outcome of secondary NHL were updated in March 1999. RESULTS: At first diagnosis of HD, the pathologists rejected 114 (2.1%) of 5,520 cases initially diagnosed as HD and rediagnosed them as primary NHL. Fifty-two (0.9%) of the remaining 5,406 patients developed a secondary NHL. One patient was excluded from further analyses because of insufficient documentation. Six patients had no further therapy because of patient refusal (n = 1) or rapidly progressive disease (n = 5). For the remaining 45 patients, overall response rate was 43% (36% complete response and 7% partial response). The actuarial 2-year freedom from treatment failure (FFTF) and overall survival (OS) for all patients was 24% and 30%, respectively, and for patients with diffuse large-cell lymphoma, it was 28% and 35%, respectively. Time of occurrence of secondary NHL after first diagnosis of HD and variables employed in the age-adjusted International Prognostic Factor Index (IPFI) significantly influenced treatment outcome. CONCLUSION: In the GHSG, the incidence of secondary NHL with 0.9% is relatively low compared with previously reported series. The prognosis of secondary NHL seems dismal and is significantly influenced by time of occurrence and the age-adjusted IPFI. In a subset of patients with secondary NHL, long-term disease-free survival could be achieved.     

Identification of prognostic factors predicting outcome in Hodgkin's lymphoma patients relapsing after autologous stem cell transplantation

BackgroundHigh-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is the standard of care for patients with relapsed Hodgkin's lymphoma (HL). However, there is currently little information on the predictors of outcome for patients whose disease recurs after ASCT.MethodsFive hundred and eleven adult patients with relapsed HL after ASCT from EBMT-GITMO databases were reviewed.ResultsTreatments administered following ASCT failure included conventional chemotherapy and/or radiotherapy in 294 (64%) patients, second ASCT in 35 (8%), and alloSCT in 133 (29%). After a median follow-up of 49 months, overall survival (OS) was 32% at 5 years. Independent risk factors for OS were early relapse (<6 months) after ASCT, stage IV, bulky disease, poor performance status (PS), and age ≥50 years at relapse. For patients with no risk factors OS at 5 years was 62% compared with 37% and 12% for those having 1 and ≥2 factors, respectively. This score was also predictive for outcome in each group of rescue treatment after ASCT failure.Conclusion(s)Early relapse, stage IV, bulky disease, poor PS, and age ≥50 years at ASCT failure are relevant factors for outcome that may help to understand the results of different therapeutic approaches.     

Salvage radiotherapy in recurrent Hodgkin's disease.

Forty-four patients with Hodgkin's disease (HD) which relapsed after chemotherapy were treated with salvage radiotherapy (S-RT) with curative intent. Patients were aged 7 to 80 years (median 32 years) at the time of S-RT and the median follow-up from S-RT was 5 years (1-15). Nine patients had recurrent HD following first-line chemotherapy and thirty five patients had refractory HD. Salvage therapy consisted of radiotherapy alone in 25 and combined chemotherapy and radiotherapy in 19 patients. The overall CR rate of salvage therapy was 66%. The overall median survival of 44 patients was 4.6 years from S-RT with 46% 5 year and 40% 10 year survivals. Age (greater than 40 years) and progression free interval (less than or equal to 1 year) were adverse independent prognostic factors for survival on multivariate analysis. The 5 and 10 year progression free survivals were 38% and 23% respectively. Adverse independent prognostic factors for progression-free survival were extranodal site of recurrence and short progression free interval (less than or equal to 1 year). We conclude that radiotherapy with or without chemotherapy has a role in the salvage of patients failing chemotherapy, particularly in those with nodal disease and progression-free interval greater than 1 year.     

Allogeneic transplantation of hematopoietic stem cells after nonmyeloablative conditioning for Hodgkin's disease: indications and results

A number of treatment options are available for patients with relapsed Hodgkin's disease (HD). Radiotherapy, salvage chemotherapy, high-dose therapy (HDT) followed by autologous transplantation, and classical or nonmyeloablative conditioning followed by allogeneic transplantation can all be effective in patients with relapsed HD. Patients with early relapse after modern first-line chemotherapy, as well as patients with primary progressive disease, will be candidates for innovative approaches including nonmyelablative stem cell transplant (NST). Although initial results with NST look promising, more time and structured study of both HD and NST will be necessary to ultimately define the role of NST in this disease.

背景与目的:自体造血干细胞移植(autologoushemotopoieticstemcelltransplantation,ASCT)支持下的大剂量化疗目前已成为治疗对化疗敏感的淋巴瘤最有效的手段之一。本研究评价自体造血干细胞移植支持下的大剂量化疗加放疗治疗预后差的中、高度恶性淋巴瘤的疗效。方法:1995年11月～2001年5月收集到的13例病例中,非霍奇金淋巴瘤(non-Hodgkinslymphoma,NHL)11例,复发霍奇金淋巴瘤(Hodgkinsdisease,HD)2例。移植前首次完全缓解(firstcompleteremission,CR1)8例,第二次完全缓解(secondcompleteremission,CR2)4例,第二次部分缓解(secondpartialremission,PR2)1例。预处理方案:单纯化疗4例;化疗加受累区放疗6例;全身放疗加化疗3例。2例采用自体骨髓移植,11例行自体外周血干细胞移植。结果:本组病例回输单核细胞(mono-nuclearcell,MNC)和粒-巨细胞系祖细胞(granulocyte-macrophagecolony-formingcells,CFU-GM)的均数(范围)分别为2.55(2.07～3.31)×109/L和1.43(0.6～2.36)×109/L。随访到2001年10月,所有患者造血功能都获得重建。白细胞恢复到≥1.0×109/L和血小板>50×109/L的中位时间(范围)分别为6(7～35)天和8(6～32)天。CR持续时间为4～57个月,中位时间为16个月,1年生存率76.9%,3年生存率46.2%。结论:自体造
