    Description / Table of Contents: ZusammenfaBung Das Mamma-Carcinom liegt in der Bundesrepublik Deutschland mit dem Dickdarmcarcinom dicht nebeneinander an 2. und 3. Stelle. Ein entscheidender Wandel in der Therapie ist unseren chirurgischen Vorvätern aus einer Zeit vor rund 100 Jahren (Dieffenbach, Rotter, Halsted) zu verdanken, die aufgrund beBerer KenntniBe der lymphatischen Anatomie begannen, die axillären Lymphknoten und die Brustmuskeln zu entfernen. Weder die VergröBerung des Eingriffs (superradikales Verfahren) noch die Verkleinerung der Eingriffe (Enucleation, partielle Mastektomie) haben sich bisher gegenüber den ausgedehnteren Verfahren als überlegen erwiesen. Eine Statistik aus rund 1000 verschiedenen chirurgischen Kliniken zeigt die Verteilung der Operationsverfahren in der westlichen Welt. Bei den reduzierten Operationsverfahren (z. B. Enucleation) besteht besonders die Gefahr, daB der verständliche Wunsch nach der erstrebenswerten Kosmetik auf Kosten der Heilchance geht.
    Notes: Summary In the German Federal Republic, carcinoma of the breast and colon lie close together as the second and third most tumors. We owe to our surgical forefathers of 100 years ago, Dieffenbach, Rotter, and Halsted, the decisive therapeutic advance whereby as a result of a better understanding of the anatomy of lymphatic drainage, excision of axillary glands and pectoralis muscle was first untertaken. Neither increasing the extent of the operation (superradical excision) nor reducing it (enucleation, partial mastectomy) has so far with any certainly proved as effective as radical mastectomy. The prevalence of various operations used in the western world was ascertained from a survey of about 1000 surgical clinics. With leB extensive operations (enucleation) there is the special danger that the understandable desire to strive for a cosmetic result may vitiate the chance of cure.

    Description / Table of Contents: Zusammenfassung Die tödlichen Krebsopfer (rund 150000 pro Jahr) haben seit 1900 in der Bundesrepublik jetzt den 2. Platz erreicht. Auch nach internistischer Schätzung werden heute 80–90% aller Tumoren primär operativ behandelt und zu 30–40% mit oder ohne Kombination von Radiotherapie geheilt. Die Chemotherapie hat in 7% einen potentiellen curativen Effekt, die Immunotherapie bis heute nur in ± 0%. Nach einer generellen Diskussion über radikale und palliative operative Techniken wird der Platz der Krebs-Chirurgie bei prophylaktischen Indikationen, bei Rezidiven und Metastasen behandelt. Spezielle Probleme folgen anhand verschiedener Organtumoren (Schilddrüse, Mamma, Oesophagus, Magen, Colon und Wilms-Tumoren. In Heidelberg besteht seit 1966 eine interdisziplinäre onkologische Einheit, die auf den beiden Säulen der akademischen Kliniken und des DKFZ installiert wurde. Ob die Spezialität einer chirurgischen Onkologie sich durchsetzen wird, ist eine Frage weiterer Erfahrung und Planung.
    Notes: Summary Cancer is now the second most frequent cause of death in the Federal Republic of Germany. According to medical estimates, surgery is the primary treatment for 80–90% of all tumors, und it is curative in 30–40% with or without concomitant radiotherapy. Chemotherapy is potentially curative in about 7 %, immunotherapy in only ± 0%. After a general discussion of radical and palliative operative techniques, the place of surgery in prophylactic indications, in recurrences, and in metastases is dealt with. Special problems occur in various organ tumors (thyroid, breast, esophagus, stomach, colon, and Wilms' tumors). In Heidelberg, an interdisciplinary oncologic group has been in existence since 1966; this group forms the basis of a tumor center, consisting of the two academic clinics and the German Cancer Research Center. Whether a speciality in surgical oncology is also needed in Germany is a question for further consideration.

    Notes: Abstract Energy spectra and angular distributions of the O+ and O 2 + product ions resulting from the He+-O2 charge transfer reaction have been measured in the collision energy range 0.5–200 eV using the crossed-beam method. The O 2 + ions represent only a minor fraction of the reaction products (0.2–0.6% over the energy range measured). In the dissociative charge transfer reaction, four main processes are identified leading to O+O+ reaction products in different electronic states. Two different mechanisms can be distinguished, each being responsible for two of the observed processes:(i) a long-distance energy-resonant charge transfer process involving thec 4∑ u − (v′=0) state of O 2 + and(ii) a slightly exothermic charge transfer process via the (III)2∏ u state of O 2 + (with the exothermicity depending on the collision energy). Angle-integrated branching ratios and partial cross sections (in absolute units) have been determined. The branching ratios of the individual processes show a pronounced dependence on the collision energy. At low energies, the O+ product ions are preferentially formed in the2 P 0 and2 D 0 excited states. The angular distributions of the O+ product ions show an anisotropic behaviour indicating an orientation-dependent charge transfer probability in the He+ −O2 reaction.
