    Description / Table of Contents: Zusammenfassung. Anhand der Daten der prospektiven deutschen Multizenterstudie der Studiengruppe Kolorektales Karzinom (SGKRK) wurden die Klinikunterschiede im 5-Jahres-Überleben mit speziellen für ein sog. Ranking geeigneten biometrischen Methoden unter Wahrung der Anonymität analysiert. Weiterhin wurde nach sog. Surrogatendpunkten gesucht, die bereits früher als 5 Jahre nach Ersttherapie eine Aussage über die Ergebnisqualität der chirurgischen Therapie ermöglichen. Hierzu ist eine gesonderte Analyse für Rectum- und Coloncarcinompatienten erforderlich. Für das Rectumcarcinom ist die Kombination von Häufigkeit örtlicher Tumorzelldissemination bei Tumorresektion (intraoperativer Einriß im Tumor und/oder Schnitt in oder durch Tumorgewebe) und Rate locoregionärer Rezidive (innerhalb von 2 Jahren) nach Operation als verläßlicher Surrogatendpunkt anzusehen. Beim Coloncarcinom konnte ein solcher nicht gefunden werden. Die postoperative Morbidität ist als Indikator für die definitive Ergebnisqualität ungeeignet. Eine sehr niedrige Rate postoperativer Todesfälle bietet keine Gewähr auf zufriedenstellende Langzeitergebnisse in der colorectalen Carcinomchirurgie.
    Notes: Summary. The data of the German Prospective Multicenter Study of the Study Group Colorectal Carcinoma (SGCRC) were analyzed with regard to interinstitutional differences in 5-year survival by statistical methods adequate for ranking and observing anonymity. Furthermore, possible so-called surrogate endpoints that allow an assessment of definite outcome after surgical treatment earlier than after 5 years were also analyzed. This requires a separate analysis for rectal and colon carcinoma patients. For rectal carcinoma, the combination of the frequency of local tumor cell spillage during tumor resection (iatrogenous tumor perforation and/or incision into or through tumor tissue) and the rate of locoregional recurrences (within 2 years after surgery) could be demonstrated as realiable surrogate endpoint. For colon carcinoma, no reliable surrogate endpoint could be found. Surgical morbidity is not an indicator of definite outcome. A very low rate of surgical mortality does not ensure satisfactory long-term results in colorectal cancer surgery.

    Description / Table of Contents: Zusammenfassung. Einleitung: Um zu prüfen, ob die Operationsmethodik die 5-Jahres-Rezidivrate und -Überlebensrate bestimmt, haben wir die Ergebnisse von 2 chirurgischen Kliniken mit unterschiedlicher Operationsmethodik (Klinik A: Entfernung des Tumors und der tumornahen Lymphknoten, Klinik B: En bloc-Resektion nach den Regeln der standardisierten Tumorchirurgie) analysiert. Patienten und Methoden: Analyse der Operationsergebnisse aller zwischen 1984–1988 operierten Patienten mit colorectalem Carcinom (Klinik A: 152 Colon- und 53 Rectumcarcinome; Klinik B: 124 Colon- bzw. 177 Rectumcarcinome). Ergebnisse: Die Lokalrezidivraten bei Klinik A signifikant höher (Coloncarcinome Klinik A 25 %, Klinik B 10 %; Rectumcarcinome Klinik A 54 %, Klinik B 16 %. Die 5-Jahres-Überlebensrate betrug bei den Coloncarcinomen in Klinik A 65 %, in Klinik B 66 %, bei den Rectumcarcinomen in Klinik A 49 %, in Klinik B 72 %. Schlußfolgerungen: Aus dieser Analyse läßt sich ableiten, daß ein colorectales Carcinom nur dort operiert werden sollte, wo die Standards der colorectalen Carcinomchirurgie eingehalten werden.
    Notes: Summary. Introduction: In order to investigate whether operative technique determines the 5-year recurrence and survival rates, we analysed the results obtained by two surgical departments using two different operative techniques. Department A: Removal of the tumour and a number of lymph nodes; department B: En-bloc resection in accordance with the requirements of standardised tumour surgery. Patients and methods: The surgical results obtained with all patients with colorectal carcinoma operated on between 1984 and 1988 (department A: 152 colon and 53 rectal carcinomas; department B: 124 colon and 177 rectal carcinomas). Results: The local recurrence rate achieved by department A was signicantly higher (colon carcinoma: department A 25 %; department B 10 %; rectal carcinoma: department A 54 %; department B 16 %). The 5-year survival rate for colon carcinoma was 65 % in department A, and 66 % in department B, the corresponding figures for rectal carcinoma being 49 % and 72 %, respectively. Conclusion: The results indicate that carcinoma of the colorectum should be operated on only at an institution that complies with the standards required for surgery of colorectal carcinoma.

    Notes: Abstract In the epidermal cells of onion (Allium cepa L.) bulb scales the endoplasmic reticulum (ER) can be subdivided into three domains: a peripheral tubular network, cisternae, and long tubular strands. The latter are the form in which the ER is moved in onion cells. During cold treatment the arrangement of the three domains changes drastically. The cisternae and long tubular strands disintegrate into short ER tubules which show rapid agitational motion. Long-distance movement is inhibited. The peripheral tubular ER network is presumably retained during cold treatment. Rewarming of previously chilled bulb scales initiates the reorganization of the ER into the three domains. The ER is partly relocated during recovery from cold treatment. Redistribution and reorganization of the ER is not affected by the microtubule-destabilizing herbicides oryzalin and trifluralin (5 μM). Cytochalasin D (2μM), however, inhibits not only the relocation of ER material, as is evident by the absence of long tubular ER strands, but also the movement of other cell organelles. The latter cluster on top of the cisternae in a manner which is characteristic of treatment with the actin-filament inhibitor. The array of actin filaments is similar in unstressed, cold-treated cells, and cells which recover from low temperatures in the presence of oryzalin or tap water alone. In the presence of cytochalasin D the actin filaments are severely fragmented. The results indicate that low temperatures most likely influence either the interaction of the force-generating system, probably myosin, with actin filaments, or the force-generating mechanism of the actomyosin-driven intracellular movement, but do not affect actin-filament integrity.
