    Description / Table of Contents: Zusammenfassung Im Hinblick auf eine Senkung der Frühtodesrate durch Infektionen wurde in einer vergleichenden Studie der Wert einer selektiven Darmdekontamination (SDD) bei der zytostatischen Behandlung von Patienten mit akuter Leukämie untersucht. Es wurden drei Gruppen gebildet: 1) SDD (Neomycin, Colistin, Nystatin) bei einfacher Umkehrisolation auf der Normalstation; 2) keine SDD, aber einfache Umkehrisolation auf der Normalstation; 3) strikte Isolation, gefilterte Luft, sterilisierte Nahrung plus SDD. Es fanden sich graduell zwischen den drei Gruppen signifikant weniger Infektionen mit Gramnegativen Keimen: Isolierstation plus SDD versus Normalstation plus SDD versus Normalstation ohne SDD. Die Frühtodesrate durch Infektionen war in der Gruppe mit SDD auf der Normalstation signifikant geringer als in der Gruppe ohne SDD, umgekehrt die Remissionsrate nach zytostatischer Behandlung signifikant höher. Die Dekontamination wurde gut vertragen.
    Notes: Summary A comparative study of infectious morbidity and mortality in neutropenic patients with acute leukemia receiving chemotherapy was undertaken to test the effects of a suppression of endogenous and ambient microorganisms. Patients were allocated to receive [1] oral antibiotics (neomycin, colistin, and nystatin) in conventional ward isolation; [2] no antimicrobial suppression but conventional ward isolation; [3] strict isolation, filtered air, sterilized food and oral antibiotics. Significantly fewer infections with Gram-negative bacilli were seen in patients with strict isolation plus endogenous microbial suppression versus patients receiving selective gut decontamination versus patients without nonabsorbable antibiotics in simple reverse isolation. The death rate from infection was significantly reduced in patients who received antibiotics for gut flora suppression in conventional ward isolation compared with the corresponding control group. In addition, a significant improvement of leukemic remission rate was seen in this group. The protocol for decontamination was well tolerated.

    Description / Table of Contents: Zusammenfassung Im Rahmen der Arbeitsgemeinschaft Knochenmarktransplantation München wurden von August 1975 bis Juni 1980 insgesamt 17 Patienten mit rezidivierter, akuter Leukämie mit Knochenmark von HLA-identischen Geschwistern transplantiert. Die antileukämische und immunsuppressive Vorbehandlung bestand aus BCNU, Cytosin-Arabinosid, Cyclophosphamid in hoher Dosierung und Ganzkörperbestrahlung mit etwa 9 Gy Körpermitteldosis an einer60Co-Doppelbestrahlungsanlage. Die Prophylaxe einer Graft-versus-Host Krankheit (GvHK) wurde in allen Fällen mit Methotrexat durchgeführt, bei neun Patienten wurde als zusätzliche GvHK-Prophylaxe das Knochenmark mit Anti-T-Zell-Globulin inkubiert, von dem die Antikörper gegen hämopoetische Stammzellen absorbiert waren. Zwei von fünf auswertbaren Patienten, die unbehandeltes Knochenmark erhalten hatten, entwickelten chronische GvHK, während kein Patient nach ATCG-Inkubation des Knochenmarkes eindeutige GvH-Krankheit bekam. Sechs Patienten leben in Vollremission zwischen einem und 33 Monaten nach Knochenmarktransplantation (KMT). Fünf Patienten starben mit Rezidiven zwischen 3 1/2 und 24 Monaten nach KMT, drei Patienten mit interstitieller Pneumonie innerhalb von 3 Monaten nach KMT und drei Patienten innerhalb von 4 Wochen ohne ausreichende Knochenmarkfunktion. Vier von 13 Patienten, die vor mehr als 6 Monaten transplantiert wurden, überleben zur Zeit 11, 14, 19 und 33 Monate in Vollremission. Unsere Ergebnisse bestätigen, daß selbst in fortgeschrittenen Stadien akuter Leukämie durch KMT noch langfristige Remissionen erreichbar sind.
    Notes: Summary Seventeen patients with relapsed, acute leukemia were grafted with bone marrow from HLA-identical siblings by the ‘Munich Cooperative Group for Bone Marrow Transplantation’ during the period from August 1975 to June 1980. The antileukemic and immunosuppressive conditioning treatment consisted of high doses of Bischlorethyl nitrosourea, Cytosine-Arabinoside and Cyclophosphamide, as well as, total body irradiation of about 9 Gy (midline body dose) from dual60Cobalt sources. Methotrexate was given to all patients for prophylaxis of graft-versus-host disease (GvHD). Nine patients received marrow that was treated with anti-T-cell globulin (ATCG) “in vitro”. — Crossreacting antibodies against hemopoietic stem cells were removed by absorption. Two of 5 evaluable patients given untreated marrow developed chronic GvHD, while patients given ATCG-treated marrow did not show unequivocal symptoms of GvHD. Six patients are in complete remission one to 33 months following bone marrow transplantation (b.m.t.) Five patients died with relapses of leukemia between 3 1/2 and 24 months following b.m.t., 3 patients died with interstitial pneumonia within 3 months of b.m.t. and 3 patients died with insufficient graft function within 4 weeks of b.m.t. Four of thirteen patients that were grafted more than 6 months ago are presently alive and in continuous complete remission at 11, 14, 29 and 33 months following b.m.t. Our results confirm that longterm remissions can be obtained with b.m.t. in patients with acute leukemia in advanced stage.

    Notes: Abstract  The long-term results of both pretreated and previously untreated patients with hairy cell leukemia (HCL) using uniformly a single 7-day course of 2-chlorodeoxyadenosine (2-CdA) by continuous infusion are reported. In addition, the probability of obtaining another response with this drug in patients who relapsed after 2-CdA treatment will be addressed. Forty-two consecutive patients (32 men, 10 women) with a median age of 56 years (range 32–75) at the time of initiation of 2-CdA treatment were analyzed. Ten patients were pretreated with either splenectomy (n=6) or interferon a (n=8) or deoxycoformycin (dCF) (n=3) or with all procedures in sequence. Two patients who did not respond to dCF did respond to 2-CdA. Median time to start of 2-CdA treatment of the ten pretreated patients was 47 months (10–160); 41 of the 42 (98%) achieved CR, and one patient reached a good partial response with a single cycle of 2-CdA. Ten of the 42 patients had no toxicities at all. Toxicities (WHO grades I–IV) were mainly of grades I and II; in one patient with a preexisting brain injury grade III neurotoxicity was seen, and one patient suffered a grade-IV infectious complication. Bone marrow biopsies were performed at the time of recovery of hematopoiesis, thereafter at 2- to 3-month intervals, then at 6 months, and finally annually in all 42 patients. Median follow-up is 32 months (2–72). Disease-free survival from start of 2-CdA treatment is 75% at 6 years; 6/42 patients relapsed. Three of these patients were treated with 2-CdA again. All three patients reached another CR (+1, +2, +13). Four of the 42 patients had a second malignancy (carcinomas of the bladder, breast, cervix, prostate gland) before receiving 2-CdA. One patient died in CR due to the second malignancy. 2-CdA is a safe and effective treatment of HCL, inducing complete remissions in the majority of patients with only a single cycle of 2-CdA and a paucity of toxities. Responses are durable and long lasting. Patients relapsing following a treatment with 2-CdA seem to respond to this drug again.

    Description / Table of Contents: Zusammenfassung Für die postoperative adjuvante Chemotherapie gibt es bisher keine genau definierte Risikogruppe, bei der die Rezidiv- oder Metastasierungsrate sicher vermindert werden kann. Weitere kontrollierte Studien müssen die Indikation für diese Therapie erst noch detaillierter herausarbeiten. Von einer generellen, unkontrollierten Anwendung der adjuvanten Chemotherapie wird abgeraten. Ähnliches gilt für die unspezifische Immunstimulation, die auch keinen gesicherten positiven Effekt hat. Für die palliative Polychemotherapie, eventuell in Kombination mit einer Antiöstrogentherapie, werden 4 verschiedene Therapie-Protokolle, die sich in unseren Händen gut bewährt haben, mit ihren Indikationen vorgestellt: Adriamycin/Cyclophosphamid (AC), Cyclophosphamid/Methotrexat/5-Fluorouracil (CMF), CMF/Vincristin/Prednison (CMFVP) und die Kombination von Adriamycin/Vincristin (AV) mit CMF auf der Basis einer Dauertherapie mit Tamoxifen.
    Notes: Summary There is no well defined group of patients with primary breast cancer which benefits from combination chemotherapy as an adjuvant treatment, since, at present, the effect of this therapy in respect to the duration of disease-free interval, survival, and possible long-term side effects remain unknown. Therefore, controlled studies need to be initiated. Similarly, there seems to be no beneficial effect from unspecific immunotherapy. As far as combination chemotherapy in advanced breast cancer is concerned, we review on four different protocols which proved to be quite successful in our hands: adriamycine/cyclophosphamide (AC), cyclophosphamide/methotrexate/5-fluorouracil (CMF), CMF/vincristine/prednisone (CMFVP), and adriamycine/vincristine plus CMF plus Tamoxifen.

    Description / Table of Contents: Zusammenfassung Die Hormontherapie des Mamma-Ca hat in jüngster Zeit durch den Nachweis von Hormonrezeptoren an den Tumorzellen und die gezielte Beeinflussung des Tumorwachstums durch kompetitive Hemmung der Rezeptoren mit Antiöstrogenen große Wandlungen erfahren. Einige der herkömmlichen hormonellen Maßnahmen haben nur noch historische Bedeutung, andere werden in Zukunft nicht mehr zur Anwendung gelangen. Ob mit einem methodisch verbessertem Nachweis und somit vertieftem Verständnis der Steroidhormonrezeptoren auf das Tumorwachstum das derzeit noch stark schematisierte Vorgehen bei der Auswahl der verschiedenen Therapieschritte zukünftig Bestand haben wird, ist fraglich.
    Notes: Summary A renewal of interest in endocrine therapy of breast cancer is resulting from the demonstration of steroid hormone receptors in tumor cells sensitive to antiestrogens and the possibility for predicting endocrine responsiveness. Therefore new therapeutical concepts have been developed and some of the established endocrine regimens have been reduced to historical interest. It is more than doubtful that the present schematization in selecting the proper kind of endocrine treatment has any future as methodical difficulties in demonstrating hormone receptors will be overcome and the understanding of their biological function will increase.
