RESUMO
BACKGROUND: Combined-modality treatment consisting of chemotherapy and consolidation radiotherapy is standard of care for patients with early-stage unfavourable Hodgkin lymphoma. However, the use of radiotherapy can have long-term sequelae, which is of particular concern, as Hodgkin lymphoma is frequently diagnosed in young adults with a median age of approximately 30 years. In the German Hodgkin Study Group HD17 trial, we investigated whether radiotherapy can be omitted without loss of efficacy in patients who have a complete metabolic response after receiving two cycles of escalated doses of etoposide, cyclophosphamide, and doxorubicin, and regular doses of bleomycin, vincristine, procarbazine, and prednisone (eBEACOPP) plus two cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy (2â+â2). METHODS: In this multicentre, open-label, randomised, phase 3 trial, patients (aged 18-60 years) with newly diagnosed early-stage unfavourable Hodgkin lymphoma (all histologies) and an Eastern Cooperative Oncology Group performance status of 2 or less were enrolled at 224 hospitals and private practices in Germany, Switzerland, Austria, and the Netherlands. Patients were randomly assigned (1:1) to receive either standard combined-modality treatment, consisting of the 2â+â2 regimen (eBEACOPP consisted of 1250 mg/m2 intravenous cyclophosphamide on day 1, 35 mg/m2 intravenous doxorubicin on day 1, 200 mg/m2 intravenous etoposide on days 1-3, 100 mg/m2 oral procarbazine on days 1-7, 40 mg/m2 oral prednisone on days 1-14, 1·4 mg/m2 intravenous vincristine on day 8 [maximum dose of 2 mg per cycle], and 10 mg/m2 intravenous bleomycin on day 8; ABVD consisted of 25 mg/m2 intravenous doxorubicin, 10 mg/m2 intravenous bleomycin, 6 mg/m2 intravenous vinblastine, and 375 mg/m2 intravenous dacarbazine, all given on days 1 and 15) followed by 30 Gy involved-field radiotherapy (standard combined-modality treatment group) or PET4-guided treatment, consisting of the 2â+â2 regimen followed by 30 Gy of involved-node radiotherapy only in patients with positive PET at the end of four cycles of chemotherapy (PET4; PET4-guided treatment group). Randomisation was done centrally and used the minimisation method and seven stratification factors (centre, age, sex, clinical symptoms, disease localisation, albumin concentration, and bulky disease), and patients and investigators were masked to treatment allocation until central review of the PET4 examination had been completed. With the final analysis presented here, the primary objective was to show non-inferiority of the PET4-guided strategy in a per-protocol analysis of the primary endpoint of progression-free survival. We defined non-inferiority as an absolute difference of 8% in the 5-year progression-free survival estimates between the two groups. Safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT01356680. FINDINGS: Between Jan 13, 2012, and March 21, 2017, we enrolled and randomly assigned 1100 patients to the standard combined-modality treatment group (n=548) or to the PET4-guided treatment group (n=552); two patients in each group were found ineligible after randomisation. At a median follow-up of 46·2 months (IQR 32·7-61·2), 5-year progression-free survival was 97·3% (95% CI 94·5-98·7) in the standard combined-modality treatment group and 95·1% (92·0-97·0) in the PET4-guided treatment group (hazard ratio 0·523 [95% CI 0·226-1·211]). The between-group difference was 2·2% (95% CI -0·9 to 5·3) and excluded the non-inferiority margin of 8%. The most common grade 3 or 4 acute haematological adverse events were leucopenia (436 [83%] of 528 patients in the standard combined-modality treatment group vs 443 [84%] of 529 patients in the PET4-guided treatment group) and thrombocytopenia (139 [26%] vs 176 [33%]), and the most frequent acute non-haematological toxic effects were infection (32 [6%] vs 40 [8%]) and nausea or vomiting (38 [7%] vs 29 [6%]). The most common acute radiotherapy-associated adverse events were dysphagia (26 [6%] in the standard combined-modality treatment group vs three [2%] in the PET4-guided treatment group) and mucositis (nine [2%] vs none). 229 serious adverse events were reported by 161 (29%) of 546 patients in the combined-modality treatment group, and 235 serious adverse events were reported by 164 (30%) of 550 patients in the PET4-guided treatment group. One suspected unexpected serious adverse reaction (infection) leading to death was reported in the PET4-guided treatment group. INTERPRETATION: PET4-negativity after treatment with 2â+â2 chemotherapy in patients with newly diagnosed early-stage unfavourable Hodgkin lymphoma allows omission of consolidation radiotherapy without a clinically relevant loss of efficacy. PET4-guided therapy could thereby reduce the proportion of patients at risk of the late effects of radiotherapy. FUNDING: Deutsche Krebshilfe.

Therapy-related acute myeloid leukemia and myelodysplastic syndromes (t-AML/MDS) represent severe late effects in patients treated for Hodgkin lymphoma (HL). Because more recent data are scarce, we retrospectively analyzed incidence, outcome, and risk factors for the development of t-AML/MDS after HL. A total of 11,952 patients treated for newly diagnosed HL within German Hodgkin Study Group trials between 1993 and 2009 were considered. At a median follow-up of 72 months, t-AML/MDS was diagnosed in 106/11,952 patients (0.9%). Median time from HL treatment to t-AML/MDS was 31 months. The median age of patients with t-AML/MDS was higher than in the whole patient group (43 vs 34 years, P < .0001). Patients who received 4 or more cycles of BEACOPP(escalated) had an increased risk to develop t-AML/MDS when compared with patients treated with less than 4 cycles of BEACOPP(escalated) or no BEACOPP chemotherapy (1.7% vs 0.7% vs 0.3%, P < .0001). The median overall survival (OS) for all t-AML/MDS patients was 7.2 months. However, t-AML/MDS patients proceeding to allogeneic stem cell transplantation had a significantly better outcome with a median OS not reached after a median follow-up of 41 months (P < .001).

Accurate clinical staging is crucial for adequate risk-adapted treatment in Hodgkin lymphoma (HL) to prevent patients from under- or over-treatment. Within the latest German Hodgkin Study Group trial generation, diagnostic findings such as histopathology, computerized tomography imaging and clinical risk factors were re-evaluated by expert panels. Here, we retrospectively analysed 5965 patients and identified 399 in who major discordant findings changed their first-line treatment allocation. Histopathology review did not confirm the initial diagnosis of HL in 87 patients. Treatment allocation was revised in 312 of the remaining 5878 patients: 176 were assigned to a higher and 128 to a lower risk group, respectively; the correct treatment group remained unclear in 8 patients. Cases of revised treatment allocation accounted for 9·8%, 6·0%, 0·8%, and 14·8% of patients initially assigned to the HD13, HD14, HD15 trials and stage IA lymphocyte-predominant HL project, respectively. Most revisions were due to wrong application of clinical stage (20·5% of 312 patients with revised treatment group), histological subtype (9·0%) or the risk factors ≥3 involved areas (46·8%) or large mediastinal mass (9·3%). In conclusion, centralized review by experienced experts changed risk-adapted first-line treatment in a relevant proportion of HL patients. Quality control measures clearly improve the accuracy of treatment and should be implemented in clinical practice.

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) accounts for â¼ 5% of Hodgkin lymphoma cases. The disease is characterized by a strong CD20 expression on the malignant cells and a more indolent clinical course compared with classic HL. Anti-CD20 antibody treatment has shown clinical activity in relapsed NLPHL. In this phase 2 trial, we investigated rituximab in newly diagnosed stage IA NLPHL patients. Four weekly applications at 375 mg/m(2) were given. Among the 28 evaluable patients, overall response rate was 100%, 24 patients (85.7%) achieved complete remission, and 4 (14.3%) achieved partial remission. At a median follow-up of 43 months, overall survival was 100%; progression-free survival at 12, 24, and 36 months was 96.4%, 85.3%, and 81.4%, respectively. No grade 3 or 4 toxicity was observed. Although treatment results with rituximab appear inferior compared with radiotherapy and combined-modality approaches in early-stage patients, investigation of anti-CD20 antibody-based combinations in NLPHL is warranted. This study was registered at www.clinicaltrials.gov as #NCT00346684.

High-dose chemotherapy followed by autologous stem cell transplantation has been shown to be feasible and highly effective in newly diagnosed primary central nervous system lymphoma. In this retrospective multicenter study, we investigated prognosis and baseline risk factors in patients with primary central nervous system lymphoma who underwent this treatment approach. We retrospectively analyzed 105 immunocompetent patients with primary central nervous system lymphoma who underwent high-dose chemotherapy followed by autologous stem cell transplantation with or without whole brain radiotherapy as first-line consolidation treated at 12 German centers between 1997 and 2011. We estimated survival rates and investigated the impact of age, performance status, serum lactate dehydrogenase level, and deep brain involvement on overall and progression-free survival. Patients were additionally categorized into three prognostic groups according to the Memorial Sloan Kettering Cancer Center prognostic model. After a median follow up of 47 months, median progression-free survival and overall survival was reached after 85 and 121 months; 2- and 5-year survival rates were 82% and 79%, respectively. The Memorial Sloan Kettering Cancer Center prognostic model did not predict survival. Only age revealed some evidence of prognostic relevance. Overall response rate was 95%; of those patients with progressive disease before high-dose chemotherapy, 7 of 20 achieved ongoing complete remission after therapy without whole brain radiation therapy. Transplantation-associated mortality was 2.8%. High-dose chemotherapy followed by autologous stem cell transplantation is a highly effective and safe treatment modality for selected primary central nervous system lymphoma patients. Superiority compared to standard chemotherapy still warrants further investigation.

With improved treatment strategies and prognosis for patients with Hodgkin lymphoma (HL), interest has increasingly focused on high-risk groups. These groups include a small proportion of patients who experience relapse or who have primary refractory disease despite state-of-the-art treatment. Although many research efforts have been made in this field, specific biological markers that reliably predict unfavorable outcome during first-line treatment are lacking. Recent analyses in HL and other malignancies, however, have demonstrated an important impact of patient-related factors, such as individual differences in hematologic toxicity and drug metabolism, on disease outcome. A different cytochrome enzyme status and slower drug clearance in female patients, resulting in higher systemic toxicity and effectiveness of treatment, indicate that sex-specific aspects are important. In this Review, we discuss the current data on hematotoxicity among male and female patients with HL and other malignancies. In addition, we highlight the potential causes of hematotoxicity and its impact on treatment outcome and the role of future strategies.

BACKGROUND AND OBJECTIVE: The BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) chemotherapy regimen for the treatment of advanced Hodgkin's lymphoma has a superior outcome, but its toxicity (mainly haematotoxicity) is pronounced and highly variable. The present study was conducted to address the role of pharmacokinetics in individual toxicity. STUDY DESIGN: Three plasma samples and a 24-hour urine collection for day 1 of the first three cycles of chemotherapy were analysed in 30 patients, and the pharmacokinetic parameters of the respective drugs were estimated by population pharmacokinetic methods (nonlinear mixed-effects model [NONMEM] software). Demographic data, doses and durations of infusion were also recorded. The effect of these parameters on platelet counts was estimated by analysis of covariance using a general linear model. RESULTS: The pharmacokinetic parameters and respective covariates were similar to the published data. The body surface area, peak concentrations of etoposide, urinary recovery of dechloroethylcyclophosphamide (formed by cytochrome P450 [CYP] 3A4) relative to the cyclophosphamide dose and number of cycles had a significant effect on toxicity. These factors explained 37% of the interindividual variability in the change in platelet counts from day 1 to day 8 of each cycle. CONCLUSION: The results show that the individual pharmacokinetics of BEACOPP drugs are an important link between dosage and toxicity. Accordingly, individualisation of treatment based on pharmacokinetics may result in more uniform toxicity. Individualisation may also allow escalation of the mean dose, which is probably related to better efficacy. As a consequence of the present study, infusion rates should be standardised, and the potential of a dose reduction in the first cycle and of CYP3A4 phenotyping should be addressed in clinical studies.

With improved prognosis for patients with Hodgkin's lymphoma (HL), interest has increasingly focused on high-risk groups such as elderly patients. Advanced age at presentation is still one of the strongest negative risk factors. Many different factors influence the prognosis in elderly patients. These include biologic differences such as more aggressive histology, different distribution of disease, more frequent diagnosis of advanced stage, and shorter history of disease. In addition, however, aging itself and associated factors such as comorbidity, reduced tolerability of conventional therapy, more severe toxicity and treatment-related deaths, failure to maintain dose intensity, shorter survival after relapse, and death due to other causes contribute to the poorer outcome in elderly patients. Besides the evaluation of specific causes and risk factors, this review highlights recent and ongoing studies for elderly patients with HL as well as international approaches and recommendations for this age group.

PURPOSE: Long-term survivors of successfully treated Hodgkin's lymphoma (HL) are at risk for late complications. Among these, infertility for female patients is of major importance. The subject of this analysis is to evaluate the menstrual status after HL therapy. PATIENTS AND METHODS: From 1994 to 1998, the German Hodgkin's Lymphoma Study Group conducted clinical trials for early-, intermediate-, and advanced-stage HL (trials HD7 to HD9) involving a total of 3,186 patients. A survey was carried out to evaluate the menstrual status after therapy. The following factors were assessed concerning their influence on amenorrhea: age, treatment, stage, and the use of oral contraceptives during chemotherapy. RESULTS: A total of 405 women aged younger than 40 years answered the study questions. After a median follow-up of 3.2 years, 51.4% of the women receiving eight cycles of dose-escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) had continuous amenorrhea. Amenorrhea was significantly more frequent after dose-escalated BEACOPP compared with doxorubicin, bleomycin, vinblastine, and dacarbazine; cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastine, and dacarbazine; or standard BEACOPP (P = .0066). Amenorrhea after therapy was most pronounced in women with advanced-stage HL (P < .0001), in women older than 30 years at treatment (P = .0065), and in women who did not take oral contraceptives during chemotherapy (P = .0002). CONCLUSION: Most women who are treated for advanced-stage HL experience amenorrhea after therapy. Amenorrhea is significantly more frequent in women with advanced-stage HL receiving eight cycles of dose-escalated BEACOPP and in women older than 30 years at first treatment. Furthermore, the data show a statistical association between the use of oral contraceptives and return of menstrual cycle, which is subject to further investigation.

PURPOSE: Several scores have described sex as a prognostic factor in patients with Hodgkin's lymphoma (HL). However, little is known how sex-specific factors influence treatment outcome. We systematically investigated sex differences with regard to pretreatment characteristics and therapy-related variables, and examined their influence on the outcome of HL patients. PATIENTS AND METHODS: This analysis comprises 4,626 HL patients of all prognostic risk groups who were enrolled onto the multicenter studies HD4 to HD9 of the German Hodgkin Study Group. At 5.5 years, 2,050 female and 2,576 male patients were analyzed. RESULTS: Male and female patients had similar prognostic factors. There was more acute chemotherapy-related hematotoxicity in women, especially more severe leucopenia (WHO grade 3/4, 69.9% female and 55.2% male; P < .0001). Importantly, this did not translate into more infections. Female patients had similar response rates but fewer relapses and deaths, leading to a significantly better freedom from treatment failure (FFTF; at 66 months, 81% female [95% CI, 79% to 82%] and 74% male [95% CI, 72% to 76%]). Severe leucopenia during chemotherapy was strongly associated with better FFTF, both for males and females. In addition, when only those patients who developed severe leucopenia within the first two cycles of chemotherapy were included, the factor maintained its protective role. CONCLUSION: The protective role of severe leucopenia suggests the testing of a more individualized therapy. In future trials, this therapy may be tailored in a response-adapted manner depending on the individual toxicity profile within the first cycles.

The treatment of Hodgkin's lymphoma has changed significantly over the last decades, rendering this entity one of the most curable human cancers. To date, about 80% of patients achieve long-term disease-free survival. Current strategies in first-line treatment aim at further improving outcome and thereby preventing therapy-induced complications, such as infertility, cardiopulmonary toxicity, and secondary malignancies. Ongoing trials for patients in early stages are investigating lower radiation doses and smaller radiation fields and possible reductions in the doses or number of cycles of chemotherapy given. For patients in advanced stages, new drug combinations with higher dose density and intensity have been developed, and are currently being evaluated in clinical trials. Approaches for relapsed Hodgkin's lymphoma comprise salvage radiotherapy, salvage chemotherapy and high-dose chemotherapy followed by autologous stem cell transplantation. In recent years, the introduction of effective salvage high-dose therapy and a better understanding of prognostic factors have remarkably improved the management of relapsed Hodgkin's lymphoma. For multiple pretreated patients antibody-based agents that showed promising results in experimental models are being investigated in clinical trials. Radioimmunoconjugates and monoclonal antibodies have demonstrated some clinical efficacy. Here, we review new aspects in the treatment of primary and relapsed Hodgkin's lymphoma as well as recent immunotherapeutic approaches.

Substantial clinical progress over the last decades has made Hodgkin's lymphoma (HL) into one of the most curable human cancers in adults. About 80% of patients in all stages and of all histological subtypes experience long-term disease-free survival. Modern treatment strategies aim to improve chemotherapy and radiotherapy, while minimizing therapy-related toxicities. Ongoing trials investigate a reduction of chemotherapy doses or cycles and the application of lower-radiation doses and smaller radiation field sizes. For patients with a specific high-risk profile, novel approaches with more intense drug combinations are currently being investigated in clinical trials. Here, we review recent approaches in the first-line treatment of early-favorable, early-unfavorable, and advanced-stage HL.

PURPOSE: The introduction of BEACOPP(escalated) (escalated-dose bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) has significantly improved tumor control and overall survival in patients with advanced-stage Hodgkin lymphoma. However, this regimen has also been associated with higher treatment-related mortality (TRM). Thus, we analyzed clinical course and risk factors associated with TRM during treatment with BEACOPP(escalated). PATIENTS AND METHODS: In this retrospective analysis, we investigated incidence, clinical features, and risk factors for BEACOPP(escalated)-associated TRM in the German Hodgkin Study Group trials HD9, HD12, and HD15. RESULTS: Among a total of 3,402 patients, TRM of 1.9% (64 of 3,402) was mainly related to neutropenic infections (n = 56; 87.5%). Twenty of 64 events occurred during the first course of BEACOPP(escalated) (31.3%). Higher risk of TRM was seen in patients age ≥ 40 years with poor performance status (PS) and in patients age ≥ 50 years. PS and age were then used to construct a new risk score; those with a score ≥ 2 had TRM of 7.1%, whereas patients who scored 0 or 1 had TRM of 0.9%. CONCLUSION: The individual risk of TRM associated with BEACOPP(escalated) can be predicted by a simple algorithm based on age and PS. High-risk patients should receive special clinical attention.

PURPOSE: Progression or relapse of Hodgkin lymphoma (HL) is common among older patients. However, prognosis and effects of second-line treatment are thus far unknown. PATIENTS AND METHODS: We investigated second-line treatment and survival in older patients with progressive or relapsed HL. Patients treated within German Hodgkin Study Group first-line studies between 1993 and 2007 were screened for refractory disease or relapse (RR-HL). Patients with RR-HL age ≥ 60 years at first-line treatment were included in this analysis. RESULTS: We identified 105 patients (median age, 66 years); 28%, 31%, and 41% had progressive disease, early relapse, or late relapse, respectively. Second-line treatment strategies included intensified salvage regimens (22%), conventional polychemotherapy and/or salvage-radiotherapy with curative intent (42%), and palliative approaches (31%). Median overall survival (OS) for the entire cohort was 12 months; OS at 3 years was 31% (95% CI, 22% to 40%). A prognostic score with risk factors (RFs) of early relapse, clinical stage III/IV, and anemia identified patients with favorable and unfavorable prognosis (≤ one RF: 3-year OS, 59%; 95% CI, 44% to 74%; ≥ two RFs: 3-year OS, 9%; 95% CI, 1% to 18%). In low-risk patients, the impact of therapy on survival was significant in favor of the conventional polychemotherapy/salvage radiotherapy approach. In high-risk patients, OS was low overall and did not differ significantly among treatment strategies. CONCLUSION: OS in older patients with RR-HL can be predicted using a simple prognostic score. Poor outcome in high-risk patients cannot be overcome by any of the applied treatment strategies. Our results might help to guide treatment decisions and evaluate new compounds in these patients.

BACKGROUND: The presumed benefits of centralization and minimum case numbers often guide health-policy decisions, but these benefits remain inadequately documented, particularly in oncology. In this study, we aim to measure the effect of the type of treatment center and/or the number of patients treated in it on the outcome of patients with Hodgkin's lymphoma. METHODS: From 1988 to 2002, 8121 patients with newly diagnosed Hodgkin's lymphoma were treated in Germany in multicenter randomized and controlled trials (RCTs) of the German Hodgkin Study Group (GHSG). Center-related effects on progression-free survival (PFS) were assessed univariately with Kaplan-Meier plots and log-rank tests, as well as with a multivariate Cox regression model. RESULTS: The 500 participating centers in Germany included 52 university hospitals, 304 non-university hospitals, and 144 medical practices specializing in hematology and oncology. No significant differences in PFS were found between patients from centers with high or low case numbers (5-year-PFS: 78.7% and 78.6% for centers with fewer than 50 and more than 50 patients, respectively) or from different types of centers [5-year-PFS: university hospital, 77.7%; non-university hospital, 79.4%; practice, 79.8%]. Even after statistical controls for the effect of other known and unknown prognostic factors and validation in further datasets, no center effects were found. CONCLUSIONS: The type of center and the minimum number of patients treated in a center have no impact on the treatment outcome of patients with Hodgkin's lymphoma in Germany. In all GHSG centers, regardless of type, the quality standards for successful treatment are apparently met on all levels of patient care.

PURPOSE: In patients with early unfavorable Hodgkin's lymphoma (HL), combined modality treatment with four cycles of ABVD (adriamycin, bleomycin, vinblastine, and dacarbazine) and 30 Gy involved-field radiotherapy (IFRT) results in long-term tumor control of approximately 80%. We aimed to improve these results using more intensive chemotherapy. PATIENTS AND METHODS: Patients with newly diagnosed early unfavorable HL were randomly assigned to either four cycles of ABVD or an intensified treatment consisting of two cycles of escalated BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone) followed by two cycles of ABVD (2 + 2). Chemotherapy was followed by 30 Gy IFRT in both arms. The primary end point was freedom from treatment failure (FFTF); secondary end points included progression-free survival (PFS) and treatment-related toxicity. RESULTS: With a total of 1,528 qualified patients included, the 2 + 2 regimen demonstrated superior FFTF compared with four cycles of ABVD (P < .001; hazard ratio, 0.44; 95% CI, 0.30 to 0.66), with a difference of 7.2% at 5 years (95% CI, 3.8 to 10.5). The difference in 5-year PFS was 6.2% (95% CI, 3.0% to 9.5%). There was more acute toxicity associated with 2 + 2 than with ABVD, but there were no overall differences in treatment-related mortality or secondary malignancies. CONCLUSION: Intensified chemotherapy with two cycles of BEACOPP escalated followed by two cycles of ABVD followed by IFRT significantly improves tumor control in patients with early unfavorable HL.

PURPOSE: To investigate the clinical characteristics and treatment outcome of patients with lymphocyte-depleted classical Hodgkin's lymphoma (LDCHL) compared with other histologic subtypes of Hodgkin's lymphoma (HL). PATIENTS AND METHODS: From a total of 12,155 evaluable patients with biopsy-proven HL treated within the German Hodgkin Study Group trials HD4 to HD15, 10,019 patients underwent central expert pathology review. Eighty-four patients with LDCHL (< 1%) were identified and confirmed. The median follow-up time was 67 months. RESULTS: Patients with LDCHL, compared with patients with other histologic subtypes, presented more often with advanced disease (74% v 42%, respectively; P < .001) and "B" symptoms (76% v 41%, respectively; P < .001). Other risk factors were also more frequent in patients with LDCHL. Complete remission or unconfirmed complete remission was achieved in 82% of patients with LDCHL compared with 93% of patients with other HL subtypes (P < .001), and more patients with LDCHL had progressive disease. At 5 years, progression-free survival (PFS) and overall survival (OS) were significantly lower in patients with LDCHL compared with patients with other HL subtypes (PFS, 71% v 85%, respectively; P < .001; OS, 83% v 92%, respectively; P = .0018). However, when analyzing the subgroup of patients who underwent treatment with intensified or dose-dense bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, patients with LDCHL (n = 39) had similar outcomes when compared with patients with other subtypes of HL (n = 3,564; P = .61). CONCLUSION: LDCHL has a different pattern from other HL subtypes with more clinical risk factors at initial diagnosis and significantly poorer prognosis. Patients with LDCHL should be treated with modern dose-intense treatment strategies.

Substantial clinical progress over the last decades has improved the first-line treatment and prognosis of patients with Hodgkin's lymphoma (HL). This success is mainly based on the introduction of combined modality treatment strategies including chemotherapy in all risk groups and important progress in radiation techniques. The knowledge emerging from numerous clinical trials as well as better staging and imaging techniques helped to develop more effective therapies. According to our current knowledge, a stage and risk factor-based allocation into early favorable, early unfavorable, and advanced stages remains a suitable instrument to tailor risk-adapted therapy. In most of the study groups, patients with early stage HL receive 2 to 4 cycles of chemotherapy followed by radiotherapy to the involved field. The treatment for advanced stages usually consists of 6 to 8 cycles, more intensive regimen, and radiotherapy for residual masses. Here, we review results from current clinical trials and discuss new therapeutic approaches in the combined modality treatment of HL.
