    Notes: Summary Acute promyelocytic leukemia (AML FAB M3, APL) and acute myelomonocytic leukemia with abnormal eosinophils (AML M4Eo) are considered distinct entities with characteristic clinical, morphological, cytogenetic, and prognostic features. Promyelocytic leukemia is characterized by abnormal promyelocytes replacing normal hematopoiesis associated with a translocation between the long arms of chromosomes 15 and 17 t (15; 17), severe coagulopathy, and responsiveness to all-trans retinoic acid (tretinoin). Characteristic features of AML M4Eo are a myelomonocytic marrow infiltration, eosinophils with abnormal immature granules positive for chloroacetate esterase, an inversion or translocation of chromosome 16, and an increased risk of meningeal relapses. Prognosis of both types of AML has been reported to be better than prognosis of the other entities combined. Since most of the published data were collected from heterogeneous patient populations treated with various chemotherapeutic regimens, we have analyzed treatment outcome of AML M3 and M4Eo in the AMLCG-85 study for patients younger than 60 years. For the total population of 594 patients of this study, CR rate was 68.89%, early death rate 11.60%, and no or partial remission was achieved in 19.51% of the cases. Of 40 patients with AML M3 or M3v complete remission was attained in 62.5%. Nine patients died within 42 days after the start of antileukemic therapy (22.5%). Of these nine, four died because of infection, five because of bleeding. Relapse-free survival rate was 59% after 3 years, significantly better than the respective curve of the other FAB types combined (35% after 3 years). In AML M4Eo, 91.7% of the 24 patients reached complete remission. The early death rate was 8.3%. No case of nonresponse was seen. Relapse-free survival rate was 49% after 3 years compared with 35% for the other types combined.

    Description / Table of Contents: Summary Between 1970 and 1988 surgery was performed on 124 patients with soft tissue sarcomas of the extremities and trunk in the University Clinics of Hamburg. Liposarcoma, malignant fibrous histiocytoma, fibrosarcoma and malignant schwannoma were the most common histological types. High-grade sarcomas (G3) predominated, with 41 %, while 26% were graded G2 and 33% G1. Resection with wide margins all round was achieved in only 54% of the patients. The quality of the operation proved to be only therapy-related prognostic factor. In addition, tumour grade, size, regional lymph node and distant metastasis and histological type proved to be relevant to the prognosis. With multivariate analysis, distant metastasis, grade, resectability and histological type retained prognostic significance. The efficacy of adjuvant chemo- and radiotherapy was related to the quality of the preceding tumour resection. In case of gross tumour the rate of either partial or complete response was 28% for chemotherapy and 22% for radiotherapy. The mean survival time was 102 months; the 5- and 10-year survival rates were 48% and 37%, respectively.
    Notes: Zusammenfassung In der Chirurgischen Universitätsklinik Hamburg wurden von 1970–1988 124 Patienten mit Weichteilsarkomen der Extremitäten und des Rumpfs operiert. Liposarkome, maligne fibröse Histiozytome, Fibrosarkome und maligne Schwannome waren die häufigsten histologischen Typen. Niedrig differenzierte Sarkome (G3) überwogen mit einem Anteil von 41%, während 26% als G2 und 33% als G1 imponierten. Bei nur 54% der Patienten wurde eine Tumorresektion mit dreidimensional weitem Sicherheitsabstand durchgeführt. Dabei stellte sich die Qualität der Operation (RO/1/2) als einziger im Rahmen der Therapie beeinflu\barer Prognosefaktor heraus. Daneben wurde in der univariaten Analyse das Tumorgrading, die Tumorgröße, die regionalen Lymphknoten- und Fernmetastasen und der histologische Typ als prognostisch relevant ermittelt. In der multivariaten Analyse behielten die Faktoren Fernmetastasen, Grading, Resektabilität und histologischer Typ statistische Signifikanz. Der Erfolg einer adjuvanten Chemo- und Strahlentherapie war erheblich von der Qualität der vorangegangenen Tumorresektion abhängig. Bei klinisch manifestem Tumor wurde mit einer Chemotherapie bei 28% der Fälle eine Voll- oder Teilremission erreicht, mit einer Strahlentherapie bei 22% der Fälle. Die durchschnittliche Überlebenszeit betrug 102 Monate, die 5- und 10-Jahres-Überlebensrate 48% bzw. 37%.
