RESUMEN
BACKGROUND: Several randomized trials have indicated that combination chemotherapy applied in metastatic colorectal cancer (mCRC) does not significantly improve overall survival when compared to the sequential use of cytotoxic agents (CAIRO, MRC Focus, FFCD 2000-05). The present study investigates the question whether this statement holds true also for bevacizumab-based first-line treatment including escalation- and de-escalation strategies. METHODS/DESIGN: The AIO KRK 0110/ML22011 trial is a two-arm, multicenter, open-label randomized phase III trial comparing the efficacy and safety of capecitabine plus bevacizumab (Cape-Bev) versus capecitabine plus irinotecan plus bevacizumab (CAPIRI-Bev) in the first-line treatment of metastatic colorectal cancer. Patients with unresectable metastatic colorectal cancer, Eastern Cooperative Oncology Group (ECOG) performance status 0-1, will be assigned in a 1:1 ratio to receive either capecitabine 1250 mg/m(2) bid for 14d (d1-14) plus bevacizumab 7.5 mg/kg (d1) q3w (Arm A) or capecitabine 800 mg/m(2) BID for 14d (d1-14), irinotecan 200 mg/m(2) (d1) and bevacizumab 7.5 mg/kg (d1) q3w (Arm B). Patients included into this trial are required to consent to the analysis of tumour tissue and blood for translational investigations. In Arm A, treatment escalation from Cape-Bev to CAPIRI-Bev is recommended in case of progressive disease (PD). In Arm B, de-escalation from CAPIRI-Bev to Cape-Bev is possible after 6 months of treatment or in case of irinotecan-associated toxicity. Re-escalation to CAPIRI-Bev after PD is possible. The primary endpoint is time to failure of strategy (TFS). Secondary endpoints are overall response rate (ORR), overall survival, progression-free survival, safety and quality of life. CONCLUSION: The AIO KRK 0110 trial is designed for patients with disseminated, but asymptomatic mCRC who are not potential candidates for surgical resection of metastasis. Two bevacizumab-based strategies are compared: one starting as single-agent chemotherapy (Cape-Bev) allowing escalation to CAPIRI-Bev and another starting with combination chemotherapy (CAPIRI-Bev) and allowing de-escalation to Cape-Bev and subsequent re-escalation if necessary. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT01249638 EudraCT-No.: 2009-013099-38.

PURPOSE: To investigate whether combined-modality treatment (CMT) with two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by extended-field radiotherapy (EF-RT) is superior to EF-RT alone in patients with early favorable Hodgkin's lymphoma (HL). PATIENTS AND METHODS: Between 1993 and 1998, 650 patients with newly diagnosed, histology-proven HL in clinical stages IA to IIB without risk factors were enrolled onto this multicenter study and randomly assigned to receive 30 Gy EF-RT plus 10 Gy to the involved field (arm A) or two cycles of ABVD followed by the same radiotherapy (arm B). Results At a median observation time of 87 months, there was no difference between treatment arms in terms of complete response rate (arm A, 95%; arm B, 94%) and overall survival (at 7 years: arm A, 92%; arm B, 94%; P = .43). However, freedom from treatment failure was significantly different, with 7-year rates of 67% in arm A (95% CI, 61% to 73%) and 88% in arm B (95% CI, 84% to 92%; P Asunto(s)

RESUMEN
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.

The purpose of this report is to determine the value of a central specialist radiologic review and to determine the image quality of computed tomography (CT) in Hodgkin disease. The HD12 protocol is a multicenter prospective randomized trial of the GHSG for advanced stages of Hodgkin disease. The indication and effectiveness of additional radiotherapy (30 Gy), in the area of initial bulky disease and of residual disease, following intensive chemotherapy using the BEACOPP schema (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, prednisone), is to be investigated. A multidisciplinary panel of radiation oncologists, radiologists, and medical oncologists reviews, blinded to treatment arms, the diagnostic imaging with comparison to the documentation forms. For patients with poor response to chemotherapy, the panel recommends radiotherapy independent of the randomization. This procedure guarantees that patients with a poor response to chemotherapy receive additional radiotherapy. Furthermore, the panel evaluates the quality of CT examinations in this multicenter study. Since July 1999, a total of 2607 CT of 371 patients have been evaluated. Helical CT showed significantly higher contrast enhancement and imaging quality than conventional CT (P < 0.001). CT from university hospitals was assessed as superior to that from other institutions (P < 0.001). Compared with the written disease documentation by the study centers, the panel assessed different extensions of disease in 814 of 2607 CT (31%), resulting in a change of stage in 17 of 371 patients (5%). After chemotherapy, 167 of 371 patients (45%) showed residual disease (>1.5 cm), and for 53 of 371 patients (14%) the panel recommended additional radiotherapy independent of the randomization arm. Patients with Hodgkin disease receive high-quality CT imaging. A central independent multidisciplinary panel markedly improves quality assurance for these study patients.

PURPOSE: To investigate whether radiotherapy can be reduced without loss of efficacy from extended field (EF) to involved field (IF) after four cycles of chemotherapy. PATIENTS AND METHODS: Between 1993 and 1998, patients with newly diagnosed early-stage unfavorable HD were enrolled onto this multicenter study. Patients were randomly assigned to receive cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) + doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for two cycles followed by radiotherapy of 30 Gy EF + 10 Gy to bulky disease (arm A) or 30 Gy IF + 10 Gy to bulky disease (arm B). RESULTS: Of 1,204 patients randomly assigned to treatment, 1,064 patients were informative and eligible for the arm comparison (532 patients in arm A; 532 patients in arm B). The median observation time was 54 months. Five years after random assignment, the overall survival (OSran) for all eligible patients was 91% and freedom from treatment failure (FFTFran) was 83%. Survival rates at 5 years after start of radiotherapy revealed no differences for arms A and B, respectively, in terms of FFTF (85.8% and 84.2%) and OS at 5 years (90.8% and 92.4%). There also were no differences between arms A and B, respectively, in terms of complete remission (98.5% and 97.2%), progressive disease (0.8% and 1.9%), relapse (6.4% and 7.7%), death (8.1% and 6.4%), and secondary neoplasia (4.5% and 2.8%). In contrast, acute side effects including leukopenia, thrombocytopenia, nausea, gastrointestinal toxicity, and pharyngeal toxicity were more frequent in the EF arm. CONCLUSION: Radiotherapy volume size reduction from EF to IF after COPP + ABVD chemotherapy for two cycles produces similar results and less toxicity in patients with early-stage unfavorable HD.

PURPOSE: To assess the incidence and outcome of secondary acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) in patients with Hodgkin's disease (HD). PATIENTS AND METHODS: Between 1981 and 1998, the GHSG conducted three trial generations for early, intermediate, and advanced HD involving a total of 5,411 patients (called HD1 through HD9). RESULTS: A total of 46 patients with secondary AML/MDS were identified. The median age at diagnosis of leukemia was 47 years (range, 22 to 79 years). Primary therapy was as follows: radiotherapy alone (n = 4); doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD; n = 1); cyclophosphamide, vincristine, procarbazine, and prednisone (COPP)/ABVD or similar (n = 30); bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) baseline (n = 2); and BEACOPP escalated (n = 9). Twelve patients developed AML/MDS after salvage therapy, including four patients who developed AML/MDS after high-dose chemotherapy with autologous stem-cell transplantation. Thirty-six of the secondary malignancies were AML, and 10 malignancies were MDS. After a median observation time of 55 months, incidence of secondary AML/MDS was 1%. Treatment for secondary AML/MDS was as follows: cytarabine (Ara-C)-containing regimens (6-thioguanin, cytarabine, daunorubicin [TAD]/high-dose cytarabine, mitoxantrone [HAM], HAM, Ida-Ara-C (idarubicin + Ara-C), Ida-Flag (idarubicin, fludarabin, Ara-C, G-CSF), and idarubicin, cytarabine, etoposide [ICE]+HAM; n = 11), TAD-chemotherapy (n = 5), other regimens (n = 3), no treatment or supportive care (n = 24), palliative oral chemotherapy (n = 3), and allogeneic stem cell transplantation (n = 9). After 24 months of observation, no difference in freedom from treatment failure and overall survival (2% and 8%, respectively) was observed in patients who developed AML or MDS. CONCLUSION: The prognosis of patients with secondary AML/MDS after primary HD is poor. Thus, emphasis should be made to improve initial treatment in an attempt to prevent this complication.

This phase 2 trial was performed to evaluate the safety and efficacy of the chimeric monoclonal anti-CD20 antibody rituximab in patients with relapsed lymphocyte-predominant Hodgkin lymphoma or other CD20(+) subtypes of Hodgkin disease (HD). Eligibility criteria required expression of the CD20 antigen on more than 30% of malignant cells. Fourteen patients were treated with 4 weekly intravenous infusions of rituximab (375 mg/m(2)). All patients had at least one prior chemotherapy (median, 2). The median time from first diagnosis was 9 years. Adverse events, such as rhinitis, fever, chills, and nausea, were usually transient and of mild to moderate grade, allowing outpatient treatment in most cases. All patients completed treatment and were eligible for a response. The overall response in 14 assessable patients was 86%, with 8 complete remissions and 4 partial remissions, and 2 patients with progressive disease. At a median follow-up of 12 months, 9 of 12 responders were in remission. The median duration of response has not been reached yet (20+ months). We conclude that rituximab is both safe and effective in a subgroup of CD20(+) patients with HD.

BACKGROUND: High-dose chemotherapy followed by transplantation of autologous haemopoietic stem cells (BEAM-HSCT) is frequently used to treat patients with relapsed Hodgkin's disease. We aimed to compare this treatment with conventional aggressive chemotherapy without stem-cell transplantation (Dexa-BEAM). METHODS: 161 patients between 16 and 60 years of age with relapsed Hodgkin's disease were randomly assigned two cycles of Dexa-BEAM (dexamethasone and carmustine, etoposide, cytarabine, and melphalan) and either two further courses of Dexa-BEAM or high-dose BEAM and transplantation of haemopoietic stem cells. Only patients with chemosensitive disease (complete or partial remission after two courses of Dexa-BEAM) proceeded to further treatment. The primary endpoint was freedom from treatment failure for patients with chemosensitive disease. Analysis was per protocol. FINDINGS: 17 patients were excluded from the study after randomisation (ten given Dexa-BEAM and seven given BEAM-HSCT). Median follow-up was 39 months (IQR 3-78). Freedom from treatment failure at 3 years was significantly better for patients given BEAM-HSCT (55%) than for those on Dexa-BEAM (34%; difference -21%, 95% CI -39.87 to -2.13; p=0.019). Overall survival of patients given either treatment did not differ significantly. INTERPRETATION: High-dose BEAM and transplantation of haemopoietic stem cells improves freedom from treatment failure in patients with chemosensitive first relapse of Hodgkin's disease irrespective of length of initial remission.

PURPOSE: To investigate whether treatment results in intermediate-stage Hodgkin's lymphoma can be improved by rapid application of non-cross-resistant drugs, the 10-drug regimen cyclophosphamide, vincristine, procarbazine, and prednisone (COPP), doxorubicin, bleomycin, and vinblastine (ABV), and ifosfamide, methotrexate, etoposide, and prednisone (IMEP), repeated every 6 weeks, was compared with conventional alternating COPP/doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) administered every 8 weeks. PATIENTS AND METHODS: From January 1988 to January 1993, 996 patients in stage I or II Hodgkin's lymphoma with at least one risk factor (massive mediastinal tumor, massive spleen involvement, extranodal disease, elevated ESR, or more than two lymph node areas involved) and all patients in stage IIIA Hodgkin's lymphoma were randomized to receive two cycles of COPP/ABVD or COPP/ABV/IMEP followed by extended-field radiotherapy. RESULTS: Both regimens produced similar rates for treatment responses (complete remission, 93% v 94%), freedom from treatment failure (80% v 79%), and overall survival (88% for both regimens) at a median follow-up time of 7 years. Most serious toxicities during chemotherapy were similar in both regimens. However, World Health Organization grade 3 and 4 leukocytopenia occurred significantly more frequently in the COPP/ABV/IMEP arm (53% v 44% of patients; P =.010). There were no differences in the number of serious infections and toxic deaths during therapy. The number of second malignancies was also the same in both arms (22 each). CONCLUSION: Alternating COPP/ABVD and rapid alternating COPP/ABV/IMEP in combination with extended-field radiotherapy are equally effective in intermediate-stage Hodgkin's lymphoma and produce excellent long-term treatment results.
