Power-Doppler-Sonographie zur Prognoseeinschätzung von Mammakarzinomen: Gegenwärtig keine Änderung des therapeutischen Managements gerechtfertigt

Introduction: Will a simple analysis of Power-Doppler sonography permit preoperative prediction of prognosis in breast cancer patients? Material and Methods: 77 breast cancer patients were preoperatively examined by high resolution ultrasound equipment using the Power-Doppler technology. The semiquantitative parameter was to analyse blood flow by Power-Doppler with regard to the relation to established parameters of prognosis (TNM; Grading; Nodalstatus). Results: Female patients with lymph node metastasis showed in every case blood flow, nodal negative patients in 85.7%. Minor differentiated tumors showed in 86% blood flow, well differentiated only in 45%. All T3 and T4 tumors examined by the Power-Doppler showed blood flow but just 33% of the Tis breast cancer. Conclusion: The assessment of Power-Doppler sonography seems to allow preoperative statements with regard to tumor grading, a possible metastatic invasion of lymph nodes and TNM stage.
