    Notes: Abstract Purpose: At present, treatment results for patients withadvanced-stage Hodgkin's disease remain unsatisfactory. Standard chemotherapyM(C)OPP (nitrogen mustard (cyclophosphamide), vincristine, procabazine, andprednisone), ABVD (adriamycine, bleomycine, vinblastine, and dacarbacine) orM(C)OPP/ABVD +/− radiotherapy fail to achieve long-term completeremission in 35% to 50% of these patients. The BEACOPP(bleomycin, etoposide, adriamycine, cyclophosphamide, vincristine,procarbazine, and prednisone) regimen was developed to improve treatmentresults by dose intensification achieved by reduced duration of treatment(time intensification) and addition of etoposide. Patients and methods: Thirty untreated patients with advancedHodgkin's disease stage IIB–IV according to the Ann Arbor classificationwere treated with the time intensified BEACOPP regimen. Each patient wasscheduled to receive eight cycles of chemotherapy with consolidatingradiotherapy to sites of initial bulk disease and to residual tumor remainingafter chemotherapy. Results: All patients were evaluable for assessment of toxicity,treatment response, freedom from treatment failure (FFTF) and survival (SV).Of 30 treated patients, 29 patients received the intended eight cycles ofBEACOPP. One patient, in clinical CR, terminated the chemotherapy at his ownrequest after six cycles and is at this time, 48 months after the end oftreatment, in complete remission. Toxicity was tolerable with WHO grade 3/4leucopenia in 28% of chemotherapy cycles and one severe (WHO grade 3)infection. No treatment-related death occurred. Cycles could generally begiven on schedule. Complete remission (CR) was achieved in all but twopatients (93%). At present, only one patient has relapsed. At a medianfollow-up of 40 months, FFTF-rate is 89% (lower confidence limit:80%). One patient died due to progressive disease. Conclusion: The BEACOPP regimen is feasible at moderate hematopoeitictoxicity. With a FFTF-rate of 89% at a median follow-up of 40 months,the treatment results are very encouraging. A prospective randomised trial hasbeen initiated to compare the BEACOPP regimen with the standard COPP/ABVDregimen in advanced-stage Hodgkin's disease.

    Notes: Bei der Planung der 3. und 4. Studiengeneration der Deutschen Hodgkin Lymphom Studiengruppe (DHSG) kamen erstmals in größerem Umfang neue biometrische Methoden zum Einsatz, die es erlaubten, die Konzeption neuer klinischer Studien auf ein theoretisch gut begründetes Fundament aufzubauen und inzwischen nachgewiesene Effekte richtig vorauszusagen. Insbesondere betraf dies die Konzeption einer moderaten Dosiseskalation bei konventionellen Chemotherapieschemata.

    Notes: Summary In a national multicentre trial in the FRG patients with Hodgkin's lymphoma in stages CS/PS III B/IV were entered into the HD 3 protocol and received induction chemotherapy with 3× (COPP+ABVD). Patients in complete remission (CR) received consolidation therapy by either radiotherapy (20 Gy IF) or chemotherapy (COPP+ABVD). Patients not in CR received salvage therapy (40 Gy in case of persisting nodal disease, else 4× CEVD chemotherapy). Between July 1983 and May 1987 230 untreated patients aged 15 to 60 qualified for this HD 3 protocol. This analysis is based on the first 137 patients evaluable for response. Of these, 86 (63%) achieved CR after induction chemotherapy. Including salvage therapy a total of 104 patients (76%) achieved CR. Univariate and multivariate prognostic risk factor analyses were performed using freedom from treatment failure (FFTF) as endpoint. Sex, age, splenectomy, bone marrow, liver and bone involvement had no prognostic impact nor had stage according to the Ann Arbor classification. In contrast, a pretreatment erythrocyte sedimentation rate (ESR) above 80 mm/h and a serum alkaline phosphatase (AP) above 230 IU/ml appeared as significant risk factors (p〈0.01, relative risk 2.3). The two parameters were not independent. Comparing a group A (ESR ≤ 80 and AP ≤ 230) versus a pooled group B (ESR〉80 and/or AP〉230) increased the difference (p〈0.001, relative risk of 2.8) which was also significant for survival (p〈0.04).

    Notes: Abstract The BEACOPP chemotherapy regimen for advanced Hodgkin's disease employs a rearranged schedule permitting a shortened three-week cycle. With haematological growth factor support, the dosages of cyclophosphamide, etoposide and adriamycin could be moderately escalated. The 3-armed multicentre HD9 trial (recruitment 1993-1998; 1300 patients randomised) aimed to compare BEACOPP with the standard COPP/ABVD chemotherapy and to detect and measure the gain in efficacy, if any, due to moderate dose escalation of BEACOPP. Eight cycles were given, followed by local irradiation. The most recent interim analysis, with 689 evaluable patients, circa 40% of all expected events and a median observation time of 27 months, showed significant differences in progression rate (P) and in two-year freedom from treatment failure (F) between the treatment arms, with escalated BEACOPP (P = 2%, F = 89%) better than baseline BEACOPP (P = 9%, F = 81%) better than COPP/ABVD (P = 13%, F = 72%). Survival was not significantly different. Acute toxicity was more severe due to dose escalation, but remained manageable. These preliminary results suggest that BEACOPP improves efficacy. Moderate dose escalation is feasible with G-CSF support and appears likely to make a worthwhile improvement in the cure rate. The results must await confirmation (or otherwise) by the final analysis including all randomised patients and sufficiently mature data.

    Notes: Abstract In this article we summarize the theoretical arguments which led us in the German Hodgkin's Disease Study Group to introduce the BEACOPP-regimen and to initiate a large randomised trial to investigate the role of moderate dose escalation in the treatment of advanced stage Hodgkin's disease. Although some indications for a role of dose were available in the early 1990s no prospective randomised trial had been undertaken. In order to obtain an impression of the shape of the essential dose response characteristic we developed a novel statistical model that could be used to analyse a set of data in which dose variations had occured. The model took tumour growth and chemotherapy effects into account. The model could be applied to clinical data on tumour control and treatment given in a patient population. The model was fitted to the data of 706 patients which had received COPP/ABVD-like regimens. It revealed considerable heterogeneity in chemosensitivity and a positive slope of the doseresponse relationship. The model was used to simulate the effect of various treatment strategies with dose escalation and schedule changes. On the basis of such simulations we predicted that shortening cycle intervals from 4 to 3 weeks should lead to small benefits (about 3% in five-year tumour control rates). In contrast, we predicted that a moderate average dose escalation by 30% of a standard chemotherapy would lead to a potential benefit in the order of 10%-15% in tumour control at five years. Subsequently we searched for a treatment scheme that would permit such a dose escalation. The BEACOPP-scheme was invented to allow the three major myelotoxic substances (cyclophsphamide, adriamycin and etoposide) to be given in the beginning of a cycle. These three substances were then subject to dose escalation in a dose finding trial. G-CSF was introduced to compensate for the myelotoxic effects. The dose level found feasible for a large multicentre setting turned out to be in the required magnitude. The HD9 trial of the GHSG was then initiated to examine whether the predicted dose response curve really exists.

    Notes: Es gibt zur Zeit 30 Staubmeßgeräte, von denen jedes oft einen nur engen, ganz bestimmten Anwendungsbereich hat. Bei Benutzung eines an sich richtig arbeitenden Meßgerätes unter falschen Voraussetzungen kommt man zu Meßergebnissen, die zu Fehlurteilen führen. Der Überblick über die derzeitigen Geräte zur Messung von gesundheitsschädlichen Stäuben unter 5 μ Dmr. behandelt zugleich den jeweiligen Anwendungsbereich der verschiedenen Meßverfahren.
