    Description / Table of Contents: Summary Basing on the disease courses of 205 patients with plasmocytoma the authors present data on the age distribution, sex distribution and prehemoblast stage. In order to utilize, apart from the 174 deceased patients, also the diseases courses of the 31 patients still alive on a given date or having survived this data, for the statistical assessment of the survival time, „indirect mortality tables” were established, similar to those used in population-statistical methods, both for the total number of cases and separately for a group of untreated, cytostatically underliminally treated and cytostatically adequately treated patients. On the basis of experiences made so far chemotherapy was considered a minimum dose of alltogether 9 gms. of Endoxan at least for 3 months. The total duration of the disease of all patients amounted to — as an arithmetic means −25.8 and the medium 15.5 months. In the untreated patients it was 16.1 or 13.2 months, in the cytostatically adequately treated patients it was 68 to 50 months. However, an inevitable error of selection has to be considered here insofar as the group of the adequately treated patients only consisted of patients, who survived at least for 5 months since the establishment of the diagnosis.
    Notes: Zusammenfassung Auf Grund der Krankheitsverläufe von 205 Plasmozytomkranken werden Aussagen zur Altersverteilung, zur Geschlechtsverteilung und zur prähämoblastischen Phase gegeben. Um neben den 174 verstorbenen Patienten auch die 31 zum Stichtage noch lebenden bzw. lebend aus der Beobachtung ausgeschiedenen Verläufe für die statistische Berechnung der Überlebenszeit mitverwenden zu können, wurden in Anlehnung an die Bevölkerungs-statistik „indirekte Sterbetafeln” aufgestellt, und zwar sowohl für die Gesamtzahl aller Krankheitsfälle als auch getrennt für eine Gruppe unbehandelter, zytostatisch unterschwellig behandelter und zytostatisch ausreichend behandelter Patienten. Als „ausreichend behandelt” wurde die Chemotherapie auf Grund der bisherigen Erfahrung dann angesehen, wenn ein Patient mindestens 3 Monate lang eine Minimaldosis von insgesamt 9 g Endoxan erhalten hatte. Die Gesamtkrankheitsdauer aller Patienten betrug im arithmetischen Mittel 25,8 und im Median 15,5 Monate. Sie lag bei den unbehandelten Patienten bei 15,1 bzw. 13,2 Monaten, bei den zytostatisch ausreichend behandelten hingegen bei 68 bzw. 50 Monaten. Hierbei war jedoch ein nicht vermeidbarer Auslesefehler insofern zu berücksichtigen, als die Gruppe der ausreichend Behandelten nur Patienten enthielt, die mindestens 5 Monate seit der Diagnosestellung erlebten.

    Description / Table of Contents: Summary The cytostatic effect of the alkaloid. Vincaleucoblastin, is morphologically similar to that of colchicin in that it causes blocking of mitosis in early metaphase, cut there are clinical and experimental differences between the two substances. The blocked mitoses show qualitative alterations in the form of polycentric and shrunken types as well as abnormalities, scattered and degenerated forms, the frequency of which has been recorded on the basis of 300 differentiation of mitoses.
    Notes: Zusammenfassung Die zytostatische Wirksamkeit des Alkaloids Vincaleukoblastin ist morphologisch in ähnlicher Weise wie beim Colchicin durch eine Blockierung der Zellmitose im Stadium der frühen Metaphase charakterisiert, obgleich klinisch und experimentell Unterschiede deutlich sind. Qualitativ zeigten die blockierten Mitosen polyzentrische und konzentrische Schrumpfformen sowie Aberrations-, Zerstreuungs- und Degenerationsformen, über deren Häufigkeit auf Grund von 300 Mitosedifferenzierungen berichtet wird.

    Description / Table of Contents: Summary In 424 patients treated with Cyclophosphamide (Endoxan, Cytoxan) a hemorrhagic cystitis was observed in 11% although there were no clinical symptoms indicating a hemorrhagic disorder. In two patients the hemorrhage was lethal. Besides a toxical damage of the blood vessels of the submucosa a direct local cytostatic action of fission products of Endoxan, which are present in the urine, may be responsible for these complications. The maximal cytostatic activity appears in the urine 2–4 hours after the application of Endoxan. This was proved by peripheral leukocyte counts in rats, which were injected with the urine of the treated patients. Thirty to forty per cent of the cytostatic activity of Endoxan are eliminated within 9 hours by the kidneys. Based on own experiences the clinical symptomatology, the morphology and the therapeutic consequences of Endoxan-induced hemorrhagic cystitis are discussed.
    Notes: Zusammenfassung Bei der Behandlung von 424 Patienten mit dem Phosphamidester Endoxan traten ohne klinische Zeichen einer hämorrhagischen Diathese in 11% hämorrhagische Blasenreizungen auf, die bei zwei Patienten durch Massenblutungen zum Tode führten. Neben einer toxischen Schädigung der submukösen Gefäße ist hierfür eine direkte lokale cytostatische Wirksamkeit von Abbauprodukten des Endoxans im Harn anzuschuldigen. Das Maximum der cytostatischen Aktivität im Harn wird 2–4 Std nach der Endoxanapplikation nachweisbar, wie Testungen am Leukocytengehalt im Blut von Ratten ergaben. 30–40% der cytostatischen Aktivität des Endoxans werden innerhalb von 9 Std mit dem Harn ausgeschieden. Die klinische Symptomatik, das morphologische Bild und die therapeutische Beeinflußbarkeit der hämorrhagischen Cystitis unter der Chemotherapie mit Endoxan werden auf Grund der eigenen Untersuchungen dargelegt.

    Description / Table of Contents: Zusammenfassung Unter 44 Patienten mit primärer oder sekundärer Panmyelopathie fanden sich 4 (9%) mit Übergang in eine akute Leukämie. Cytologische Veränderungen, die für eine Präleukämie sprachen, fanden sich im präleukämischen Stadium nicht. Die Möglichkeit, eine Panmyelopathie und eine Präleukämie durch cytologische, cytochemische und cytogenetische Untersuchungen, durch die Agar-Kulturtechnik, die „liquid culture“ und die Bestimmung der „reverse transscriptase“ zu unterscheiden, wird diskutiert.
    Notes: Summary In a group of 44 patients with primary and secondary aplastic anemia, four (9%) developed an acute leukemia. Cytological changes that pointed to a preleukemia were not observed during the preleukemic stage. The possibility is discussed whether a aplastic anemia and a preleukemia can be distinguished by cytological, cytochemical and cytogenetic tests, by agar-culture technique, liquid-culture and determination of reverse transcriptase.

    Description / Table of Contents: Summary Dibrommannit (DBM=1,6-dibromo-1,6-dideoxy-d-mannitol) presents a cytostatic agent of the alkylating type. After oral application it is quickly and completely absorbed in the intenstine and is reabsorbed after the passage of the liver and gall bladder. Consequently its activation is markedly retarded and shows a cytostatic active blood level during 48 hours and more. DBM has a high selectivity of action on the granulopoiesis similar to busulphan. Clinical results in 32 patients are reported, twentynine of them having chronic myelocytic leukemia with 128 courses of treatment and a maximal period of therapy of 37 months. The average total dose was 23 g, the maximal dose 152 g. The dose per course was 5–7 g and the duration 24 days in average with a daily dose about 200–500 mg orally. Remissions could be achieved in 85%. In 38% they were complete remissions with normalization of the blood picture and complete regressions of the hepato- and splenomegaly. The mean duration of the remissions was 37 days, if a reneval increase of the white cell count above 10000 was taken as a yardstick. Ninetythree days passed in the average until the next maximum leukocyte count was observed. DBM intensively decreased the leukocytes. Thrombocytes and erythrocytes, however, were only slightly involved. The decrease of the white cells continued in some degree even further 3–4 months after the withdrawal of the compound. Leukopenie below 2000 was seen in 5%, thrombopenic purpuras in 4%. Initial effects of DBM occurred sooner than after busulphan treatment. Splenomegaly reacted more readily. DBM was even active in cases resistant to busulphan. After long term treatment with DBM, 4 patients developped a resistance. In myeloblast crisis DBM was ineffective.
    Notes: Zusammenfassung Das Cytostaticum Dibrommannit zeigt ein dem Busulfan ähnliches, in vivo jedoch stark verzögertes alkylierendes Verhalten mit hoher Wirkungsselektivität auf die Granulopoese. Wie die klinischen Ergebnisse bei 32 Patienten, davon 29 chronischen Myelocytenleukämien mit insgesamt 128 Behandlungskuren, zeigen, sind bei oralen Dosen von 5–7 g je Kur Remissionen bei 85% der Myelocytenleukämien zu erreichen. DBM senkt die Leukocytenzahl intensiv, während Thrombocyten und Erythrocyten nur wenig beeinträchtigt werden. DBM wirkt rascher und auf die Milzschwellung intensiver als Busulfan und ist auch bei busulfanresistenten Fällen noch wirksam.

    Notes: Summary The present intensification of cancer chemotherapy has resulted in increased toxicity. Nausea and vomiting are often severe and prolonged, rendering a patient unfit for further treatment. This review summarizes the current understanding of the physiology of vomiting and the pharmacology and efficacy of the antiemetics in clinical use. It also discusses new approaches with agents, such as cannobinoids, high-dosage metoclopramide, and high-dosage corticosteroids. The new agents are superior to standard antiemetic drugs as demonstrated in a number of trials.

    Description / Table of Contents: Summary Peripheral blood lymphocytes from 30 patients with chronic lymphocytic leukemia (CLL) and 18 patients with malignant non-Hodgkin's lymphomas in leukemic phase were studied for rosette-formation with neuraminidase-treated mouse erythrocytes. The proportion of rosette-forming cells in CLL was significantly higher (p〈0.001) than in 12 cases of lymphoplasmacytoid malignant lymphoma (LPL). Our results suggest that this test may be a helpful method in the differentiation of CLL from leukemic LPL, which usually can not be distinguished by morphological criteria alone.
    Notes: Zusammenfassung Blutlymphozyten von 30 Patienten mit CLL und 18 Patienten mit leukämischen Non-Hodgkin-Lymphomen wurden auf ihre Fähigkeit zur Rosettenbildung mit neuraminidase-behandelten Mauserythrozyten untersucht. Der Anteil rosettenbildender Zellen bei CLL war signifikant höher (p〈0.001) als bei 12 Fällen von lymphoplasmozytoidem malignen Lymphom (LPL). Unsere Ergebnisse weisen darauf hin, daß dieser Test eine wertvolle Methode zur Differenzierung zwischen CLL und leukämischem LPL darstellen kann, die normalerweise aufgrund morphologischer Kriterien allein nicht unterschieden werden können.

    Notes: Summary Twenty patients with cancer previously unresponsive to antiemetic treatment of chemotherapy-induced nausea and vomiting were treated with the new tetrahydrocannabinoid Levonantradol. 15 patients experienced substantial relief and 10 of them preferred the drug for further courses. These observations suggest that Levonantradol can be beneficial to patients refractory to conventional antiemetic therapy.
