    Description / Table of Contents: ZusammenfaBung Unter Berücksichtigung der jüngsten Entwicklungen auf dem Gebiet der Thrombolysetherapie und der GefäBchirurgie werden je ein praktikables Therapiekonzept für die akuten Becken- und Beinvenenthrombosen bzw. für die akute Lungenembolie vorgeschlagen und ausführlich begründet. Es wird auf die Entwicklung einer BehandlungBtrategie hingewiesen, die alle physikalischen, medikamentösen und chirurgischen MaBnahmen optimal kombiniert.
    Notes: Summary In view of recent developments in thrombolytic therapy and in vascular surgery, practical treatment schedules are proposed for both superficial and deep venous thromboses of the leg and acute pulmonary embolism. The optimal selection and combination of physical, medical, and surgical measures are advocated.

    Notes: Summary 31 adult patients (study A) with acute myelocytic leukaemia were treated for remission induction with cytosine arabinoside (ARA-C, 100 mg/ m2/day) by a 7 (5) day continuous infusion. 3 (2) doses of daunorubicin (DNR, 45 mg/m2 i.v.) were added at daily intervals. For maintenance 5 day ARA-C was given monthly in sequential combination with DNR, thioguanine (TG), or ifosfamide (IFOS). 16 (52%) patients achieved complete remission (C.R.) after 1.8 (1–23) courses and 6.7 (3–10) weeks from treatment start. The median survival for responders and non-responders was 11.5 months, early death rate within 6 weeks was 3 (10%). Median remission duration was 13.5 months. Among 11 patients surviving for 7–22 months 7 patients are in first remission for 5.5–20.5 months. DNR, IFOS and TG were not given before the 3rd day of ARA-C infusion. In a previous group of 34 leukaemic patients and in 44 therapy courses DNA histograms of bone marrow cells using pulse cytophotometry showed marked accumulation in S-phase for 75% of courses. Also (G2 + M)-cells in the DNA distribution and thymidine pulse labelling indices were markedly increased in most cases, whereas thymidine uptake by scintillation counter was diminished and mitotic indices had not changed significantly. In now 15 patients (study B) the induction regimen was intensified by adding vincristine (VCR, 2 mg i.v.) and 3 doses of IFOS (600 mg/m2 i.V.). Preliminary results are 50% C.R. after 1,7 (1–2) courses and 6.8 (5–10) weeks from initiation of therapy. 2 patients died in the first 6 weeks. Modification and intensification of established drug combinations for AML on the basis described appear reasonable and possible.

    Description / Table of Contents: Summary Cytosine arabinoside (ARA-C) and daunorubicin (DNR) (7+3 regimen) produced complete remission (C.R.) in 16 of 31 adult patients with ANLL (regimen A). Addition of vincristine (VCR) and ifosfamide (IF) revealed C.R. in 5 of 11 patients (regimen B). Dosage escalation for ARA-C and DNR and additional thioguanine (T.A.D. regimen) produced C.R. in 5 of 9 patients when ARA-C was given by continuous infusion (regimen D) and in 8 of 10 patients when given by bolus injections (regimen F). Clearance of blasts from the bone marrow by the first course was achieved in 11 of 14 patients by the T.A.D. regimens D and F vs. 15 of 38 patients by regimens A and B (p〈0.05). Time to recovery of neutrophils and platelets after one course of D or F was not prolonged as compared to A and B provided that clearance of bone marrow blasts was adequate. Increased dose of ARA-C by continuous infusion (D) instead of bolus injections (F) induced unacceptable gastrointestinal toxicity. In (only evaluable) regimen A median remission duration was 11.5 (1-31+) months. In patients with adequate blast clearance by the first course median remission duration was 19 (5-31+) months vs. 2.5 (1–6) months in the delayed blast clearance group (p〈0.001). In patients under 60 years of age in regimens D and F 11 of 11 achieved C.R. vs. 18 of 34 in A and B (p〈0.025). In patients receiving chemotherapy at original dosage 12 of 14 in regimens D and F achieved C.R. vs. 13 of 26 in A and B (p〈0.1).
    Notes: Zusammenfassung Cytosin-Arabinosid (ARA-C) und Daunorubicin (DNR) (7+3-Schema) führten bei 16 von 31 erwachsenen Patienten mit ANLL zu einer kompletten Remission (C.R.) (Regime A). Das identische Schema erweitert durch Vincristin (VCR) und Ifosfamid (IF) ergab eine C.R. bei 5 von 11 Patienten (Regime B). Dosissteigerung für ARA-C und DNR sowie Ergänzungen durch Thioguanin (TG) (T.A.D.-Schema) ergab C.R. bei 5 von 9 Patienten, wenn ARA-C kontinuierlich infundiert wurde (Regime D) und bei 8 von 10 Patienten wenn ARA-C als Bolus-Injektionen gegeben wurde (Regime F). Eine adäquate Blastenreduktion im Knochenmark bereits nach dem ersten Kurs zeigten bei den T.A.D.-Schemata D und F 11 von 14 Patienten gegenüber 15/38 bei A und B (p〈0,05). Die Erholungszeit der Neutrophilen und Thrombozyten war nach einem D- oder F-Kurs nicht länger als nach einem A- oder B-Kurs, sofern eine adäquate Blastenreduktion erzielt wurde. Erhöhte Dosis von ARA-C als Dauerinfusion (D) statt Bolusinjektion (F) verursachte inakzeptable gastro-intestinale Nebenwirkungen. Nach dem am längsten verfolgten Regime A betrug die mediane Remissionsdauer 11,5 (1-31+) Monate, und zwar bei Patienten mit adäquater Blastenreduktion durch den ersten Kurs 19 (5-31+) Monate vs. 2,5 (1–6) Monate bei Patienten mit verzögerter Blastenreduktion (p〈0,001). Bei Patienten unter 60 Jahren erreichten 11/11 bei den Regimen D und F eine C.R. gegenüber 18/34 in A und B (p〈0,025). Bei den Patienten ohne Dosisreduktion erreichten 12/14 bei den Regimen D und F und 13/36 bei A und B eine C.R. (p〈0,1).
