    Nucleolar organizer regions in myogenic stromal tumours of the stomach (1989)
    Springer
    Virchows Archiv 415 (1989), S. 317-321 
    Details
    ISSN: 1432-2307

    Notes: Summary Silver staining of nucleolar organizer regions (AgNOR) was studied in 26 primary benign and malignant gastric stromal tumours of myogenic origin. The absolute number of AgNOR per nucleus and the size of AgNOR were compared with histomorphologic features of the tumours. The total number of AgNOR per nucleus in epithelioid and spindle cell leiomyosarcomas significantly (p〈0.001) exceeded that in leiomyomas, cellular leiomyomas and epithelioid leiomyoblastomas. The mean number or the size of AgNOR did not correlate with the number of mitoses or the tumour size. In addition, large and bizarre AgNOR were seen predominantly in histologically malignant tumours. Only one exceptional epithelioid leiomyoblastoma recurred despite a lack of conventional characteristics of malignancy and a low AgNOR count. Therefore, quantitative determination of the number of AgNOR is a new independent variable in myogenic gastric tumours. It provides additional information for the histopathological evaluation of this heterogenous group of mesenchymal tumours.

    Nachweis von Carotisthrombosen mit 113m-Indium-Fibrinogen (1971)
    Springer

    Description / Table of Contents: Zusammenfassung Es wurden bei 35 Probanden extrakranielle Carotisthrombosen mit intravenös injiziertem 113m-Indium-Fibrinogen markiert und szintigraphisch nachgewiesen. Davon besaßen 10 Verschlüsse und 7 Stenosen der A. carotis interna; in 18 Fällen waren die extrakraniellen Carotiden bds. angiographisch unauffällig. 14mal war das Computerszintigramm in der Gruppe der Stenosen und Verschlüsse positiv, 3mal negativ. Negative Szintigramme fanden sich 2mal bei beidseitigen Thrombosen und bei einem mindestens 3 Jahre alten Verschluß. Unterschiede zwischen Stenosen und Verschlüssen ergaben sich im Szintigramm nicht. In der Kontrollgruppe waren 13 Szintigramme negativ und 5 positiv. Die 5 positiven Befunde betrafen 1 Vertebralisstenose und 4 gleichseitige intrakranielle Thrombosen (Syphon und A. cerebri media). Der Methode kann für die Vorfelddiagnostik extrakranieller Carotisthrombosen Bedeutung zukommen, weil sie eine gezieltere Anwendung der Angiographie gestattet.
    Notes: Summary An extracranial thrombosis of the carotid artery was visualized by scintigraphy in 35 patients through the intravenous injection of 113m Indiumfibronogen. 10 of them showed occlusions and 7 a stenosis of the internal carotid artery, in 18 other cases the extracranial carotids were angiographically inconspicuous on both sides. In the patient group with stenoses and occlusions the computer scintigram was positive in 14 cases and negative in 3. Negative scintigrams were obtained twice in the presence of a bilateral thrombosis and an occlusion dating back a minimum of three years. There was no difference between stenoses and occlusions as regards the scintigrams. The control group showed 13 negative and 5 positive scintigrams. These 5 positive findings included 1 vertebral artery stenosis and 4 bilateral intracranial thromboses (siphon and arteria cerebri media). This technique can be of great importance as a screening method in the diagnosis of thromboses of the extracranial carotid artery because it permits a more exact application of angiography.

    Metastatic potential of small and minimally invasive breast carcinomas (1994)
    Springer

    Notes: Abstract Invasive ductal mammary carcinomas (IDC) of 1 cm in tumour size or less account for less than 20% of all IDC. We have observed 167 such cases at our Institution between 1985 and 1989. These were divided into carcinomas with an extensive or predominant intraductal component (EIC or PIC, being least 2× or 4× larger than the invasive component; 90) and compared statistically with the control group (no EIC or PIC; 77) for known prognostic factors and for their metastatic behaviour. Lymph nodes were step sectioned in order to detect occult micrometastases. The median follow up time was 62.6 months. Lymph node metastases were seen in 10% of pT1a and 19% of pT1b cases. Significant differences were found when comparing the EIC/PIC group with the control group (pT1a: 11% vs. 0%, pT1b: 37% vs. 11% lymph node metastases). Also, axillary and infraclavicular recurrence rates were higher for EIC/PIC carcinomas compared with other IDC of ≤1 cm (9.3% vs. 4.2%). This significantly adverse metastatic behaviour of the EIC/PIC tumours may be in part due to the more frequent occurrence of multifocal tumours in this group (in 43% vs. 6%), resulting in a greater tumour burden. We conclude that the overall risk of lymph node metastasis is not negligible in carcinomas of 1 cm or less in diameter with the risk being more than doubled for carcinomas with an intraductal component exceeding the invasive tumour by a factor of two. These differences were relevant only to regional metastases; the risk for distant metastasis and survival was identical after 5 years.
