    Notes: Summary Twenty four patients with high grade malignant NHL (stage II 8, stage III 4, stage IV 12 patients respectively) were treated with a response-oriented regimen: Treatment was initiated according to the CHOP-protocol. Patients achieving at least a partial remission after 2 and a complete remission (CR) after 4 cycles were continued on CHOP to a total of 9 cycles. Patients not meeting these criteria were switched to a combination of Etoposide, Ifosfamide, Methotrexate, and Bleomycin (VIM-Bleo). With CHOP treatment, 16 patients (67%) achieved a CR. Of the remaining 8, 7 were treated with VIM-Bleo; 5 of these entered CR for a overall CR rate of 21/24 (88%). With a median follow up of 28 months 7 patients relapsed: 6 relapses occurred in patients with a rapid initial response and treated only with CHOP. We conclude, that there is a significant risk of relapse even in patients readily responding to CHOP and that consolidation therapy with a non cross-resistant regimen may improve results in these patients.

    Notes: Summary 3,4-dihydro-6-[4-(3,4-dimethoxybenzoyl)-1-piperazinyl]-2(1H)-quinolinone (OPC-8212) is a quinolinone derivative with positive inotropic properties. In order to elucidate the effect of OPC-8212 on the haemopoietic system we studied its in vitro effect on bone-marrow progenitor cells (granulocyte/monocyte colonyforming units [CFU-GM] and erythroid burst-forming units [BFU-E]), on the proliferation and secretion of granulocyte/monocyte colony-stimulating factor (GM-CSF) and interferon-γ (IFN-γ) by peripheral lymphocytes, and on GM-CSF secretion by fibroblasts from healthy individuals. The dose-effect relations of OPC-8212 on CFU-GM proliferation and on lymphocytic GM-CSF secretion showed no effect at very low drug concentrations, with a threshold at the lower end of the therapeutic range and highly significant dose-dependent inhibition at concentrations above that threshold. BFU-E, peripheral lymphocyte proliferation and lymphocytic IFN-γ secretion were depressed, although to a lesser extent, in a linear dose-dependent fashion. OPC-8212 did not affect GM-CSF secretion by one strain of fibroblasts but reduced it at higher concentrations in assays with another strain of cells. We conclude that direct toxic effects on bone-marrow progenitor cells, in combination with the inhibition of cytokines involved in the regulation of haemopoiesis in certain susceptible individuals, may be responsible for idiosyncratic reactions to OPC-8212.

    Description / Table of Contents: Zusammenfassung Bei 433 Patienten mit Probeexcision im Bereich des Halses fanden sich neben Lymphadenitiden in erster Linie hämatologische Malignome und Metastasen maligner Tumoren. In 4,8 % traten behandlungsbedürftige Komplikationen auf, zum einen Wundheilungsstörungen (Hämatome, Entzündungen), zum zweiten neurologische Komplikationen des Nervus accessorius. Bei 4 Patienten bildeten sich diese vollständig zurück, einmal blieb eine Parese des Musculus deltoideus bestehen. Die Analyse des Krankengutes läßt erkennen, daß vor allem ungeeignete Narkoseverfahren (Lokalanaesthesie) bei in der Tiefe gelegenen, schlecht abgrenzbaren Tumoren zu Komplikationen geführt hatten.
    Notes: Summary In 433 cervical biopsies lymphadenitis, metastases of malignant tumors and of the haematologic system could be found first of all. In 4.8 % complications needed a further treatment, firstly trouble in wound healing (haematoma, inflammation), secondly neurological complications of the accessorial nerve. These complications receded in 4 patients completely, in one patient a paralysis of the deltoid muscle continued. The analysis of our patients suggested that unsuitable anaesthesia (local anaesthesia) for deeper-seated, badly demarked tumors is responsible for most of the complications.
