    Description / Table of Contents: Zusammenfassung Von 1973-1986 wurden 226 Kardiacarcinome operiert. Seit I980 wurde neben dem abdominalen (n = 56) zunehmend das abdominale-transhiatale (n = 3I) gegenüber dem abdominothorakalen Vorgehen (n = 20) bevorzugt. Die Resektionsraten konnten von 58% auf 75% seit 1980 gesteigert werden. Die Letalität nach abdominaler/transhiataler Gastrektomie betrug seit I980 9,1%. Die 5-Jahresüberlebensraten waren nach abdominaler/transhiataler gegenüber abdominothorakaler Gastrektomie statistisch nicht verschieden (29,7 + 8,4% vs. I7,9 + 8,7%), auch nicht in den jeweiligen Tumorstadien I/II und III/IV (UICC 1978). Radikale abdominothorakale Eingriffe scheinen beim Kardiacarcinom keinen Vorteil zu bringen.
    Notes: Summary From 1973 to I986, 226 carcinomas of the gastric cardia were operated on. Since I980, in addition to abdominal gastrectomy (n = 56), an increasing number of abdominotranshiatal (n = 3I) and abdominothoracic (n = 20) operations have been performed. The resection rate has increased from 58% to 75% since 1980. The mortality has been 9.I% after abdominal/transhiatal gastrectomy since I980. The 5-year survival rates after abdominal/transhiatal procedures did not differ statistically in comparison with abdominothoracic operations (29±8%/18±9%), also not in the corresponding tumor stages I/II and III/IV (UICC 1978). Extensive abdominothoracic gastrectomies with a higher risk do not seem to provide anv advantaee in carcinomas of the gastric cardia.

    Description / Table of Contents: Synthesis and NMR Spectroscopic Studies of tert-Butylimino-cyclopentadienylvanadium(V) Compounds tC4H9N=VCpX2 (X=SR, SeC6H5, Br, I)Syntheses of the cyclopentadienylvanadium(V) compounds tC4H9N=VCpX2 (X=SR, SeC6H5, Br, I) tC4H9N=VCp (StC4H9) and tC4H9N=VCp[S—(CH2)3—S] (4) are described starting from tC4H9N=VCpCl2. tC4H9N=VCl3 reacts with BBr3 and BI3 by halogen exchange forming the trihalogenides tC4H9N=VX3 (X=Br, I). All compounds obtained are characterized by 1H and 51V NMR spectroscopy. 4 has been found by X-ray diffraction analysis to be a distorted tetrahedral vanadium complex with a chair conformation of the VS2C3-ring.
    Notes: Die Darstellung der Cyclopentadienyl-vanadium(V)-Verbindungen tC4H9N=VCpX2 (X=SR, SeC6H5, Br, I), tC4H9N=VCp(StC4H9) und tC4H9N=VCp[s—(CH2)3—S] (4) wird beschrieben; als Ausgangsverbindung wird tC4H9N=VCpCI2 eingesetzt. tC4H9N=VCl3 reagiert mit BBr3 und Bl3 unter Halogenaustausch und Bildung der Trihalogenide tC4H9N=VX3 (X=Br, I). Alle dargestellten Verbindungen werden 1H- und 51V-NMR-spektroskopisch charakterisiert. Die Röntgenstrukturanalyse von 4 zeigt das Vanadiumatom in einer verzerrt tetraedrischen Anordnung der Liganden; der VS2C3-Ring liegt in der Sesselkonformation vor.
