    Notes: Abstract Purpose: A new hemostatic puncture closure device (HPCD) was evaluated following femoropopliteal angioplasty. Efficacy in hemostasis and complications were compared between manual compression and the new system. Methods: One hundred patients undergoing percutaneous interventional procedures were randomly assigned to receive either manual compression or HPCD. The time to complete hemostasis (when a compression bandage was applied) was noted as well as complications such as hematoma or arterial stenosis at the puncture site. Follow-up was by clinical examination and color-coded duplex sonography (CCDS). Results: With the HPCD, immediate hemostasis was achieved in 22 patients (44%). Discrete oozing without the necessity of external compression or further consequences was observed in 11 patients. Mean manual compression time was 25 (± 20) min including application of the pressure bandage. Eleven patients needed additional manual compression and technical failures were observed in 6 patients (12%). The compression time in these 17 cases was 27 (± 12) min. Subcutaneous hematomata with a diameter of more than 5 cm developed in 15 of 48 patients in the HPCD group and in 14 of 48 patients in the manual compression group. No surgical or percutaneous intervention was necessary. The complication rate was comparably low in the experimental and control groups. Conclusion: Compared with manual compression HPCD is faster and more accurate for sealing the arterial puncture defect following angioplasty. After an initial learning curve, it is easy to handle and time-saving as well as convenient for the patient. Furthermore, immediate and full anticoagulation is possible and arterial inflow is not compromised. A drawback is the necessity of an 8 Fr sheath. Nevertheless, the complication rate is comparably low for both methods.

    Description / Table of Contents: Purpose: This retrospective study was designed to evaluate the role of adjuvant radiotherapy for surgically treated endometrial carcinoma. Patients and Methods: From 1980 through 1988, 541 patients were treated with either intravaginal cuff irradiation with a high-dose-rate (HDR) Iridium-192 remote afterloading technique (n = 294) or with combined HDR-brachytherapy and additional external pelvic irradiation to 54 Gy (n = 247) after surgery for endometrial cancer. Afterloading irradiation was administered in 4 fractions 4 to 6 weeks after surgery. A dose of 30 Gy was delivered at a depth of 0,5 cm from the vaginal mucosa. Results: Patients with HDR-brachytherapy alone showed a 5-year survival of 94.3% for Stage I and 73.6% for Stage II (p = 0.0007). Patients who received both brachytherapy and additional external pelvic irradiation had a 5-year survival of 94.1% for Stage I, 81.1% for Stage II, 70.4% for Stage III and 46.9% for Stage IV (p = 0.0001). The main predictors for survival in a multivariate analysis were stage and grading. Patients with combined radiotherapy had a local recurrence rate of 3.2%, whereas patients with brachytherapy alone who were better selected and had more favorable prognostic factors showed a recurrence rate of 2%. Low-risk patients (Stage I, Grade 1, low infiltration) in the HDR-brachytherapy group had 6 relapses, mainly caused by insufficient treatment on the basis of papillary histology. High-risk patients with poorly differentiated tumors, which infiltrate more than half the myometrial wall might benefit from additional external radiotherapy in terms of reduction of local recurrence and better survival. Fife-year actuarial survival rate was 93.6% after combined radiotherapy vs 86.7% after brachytherapy alone. Complications were graded according to the RTOG scoring system. Severe late complications were fistulas of bladder and/or bowel, which orrurred in 2.8% in the comnbined radiotherapy group, and 0.7% in the HDR brachytherapy group. Conclusions: Low-risk patients should be generally treated postoperative with HDR-brachytherapy alone. Combined radiotherapy decreased pelvic relapses for high-risk patients with overall low complication rates. We conclude that an individually adjusted postoperative radiotherapy allows a well tolerated treatment with excellent results.
    Notes: Ziel: Im Rahmen der Diskussion um die Wertigkeit der postoperativen Strahlentherapie bei Patientinnen mit einem Endometriumkarzinom haben wir das Patientengut der Klinik und Poliklinik für Strahlentherapie der Martin-Luther-Universität Halle-Wittenberg analysiert. Patienten und Methode: In diese retrospektive Analyse wurden die Daten von 541 zwischen 1980 und 1988 postoperativ bestrahlten Patientinnen aufgenommen. Die Auswertung der Daten erfolgte getrennt nach Therapiemodi, entweder einer alleinigen intravaginalen Strahlentherapie (HDR-AL) mit Iridium-192 oder aber einer Kombination von HDR-AL und zusätzlicher perkutaner Bestrahlung. Ergebnisse: Im Stadium I betrug die Fünf-Jahres-Überlebensrate nach HDR-AL 94,3%, im Stadium II 73,6% (p=0,0007). Ebenfalls signifikant war die Abhängigkeit der Fünf-Jahres-Überlebensrate vom Grading: Sie betrug 94,1% bei G1-, 91,9% bei G2- und 78,9% bei G3-Formen (p=0,0007). Nach kombinierter Strahlentherapie betrug die Fünf-Jahres-Überlebensrate im Stadium I 91,8%, Stadium II 81,1%, Stadium III 70,4% sowie im Stadium IV 46,9% (p=0,0001). Durch eine multivariate Analyse der Daten wurde die Abhängigkeit der Überlebensraten vom Stadium und Differenzierungsgrad gefunden. Lokalrezidive traten bei 2% der Patientinnen nach HDR-AL und bei 3,2% nach kombinierter Strahlentherapie auf. Ein wichtiger Einflußfaktor auf das Auftreten von lokoregionären Rezidiven war die Infiltrationstiefe. Low-risk-Patientinnen, die zusätzlich perkutan bestrahlt worden waren, hatten mit 93,3% eine ebenso gute Überlebenswahrscheinlichkeit wie Patientinnen mit alleinigem HDR-A: (94,8%), wobei in dieser Gruppe sechs Rezidive auftraten. Die Risikofaktoren Diabetes Mellitus, Hypertonie und/oder Adipositas bestanden bei 31,6% aller Patientinnen. Die Rate an schweren chronischen Nebenwirkungen betrug 2,8% bei allen kombiniert strahlentherapeutisch behandelten Patientinnen. Nach alleinigem HDR-AL wurden bei zwei diabetisichen Patientinnen (0,7%) Rektum-Scheiden-Fisteln beobachtet. Schlußfolgerung: Mit dem Einsatz der individuellen postoperativen Strahlentherapie bei möglichst exaktem Staging steht ein relativ nebenwirkungsarmes Behandlungskonzept mit ausgezeichneten Therapieergebnissen zur Verfügung. Der Verzicht auf eine postoperative Strahlentherapie ist nach unserer Auffassung derzeit nicht angebracht und sollte sehr sorgfältig begründet werden.
