Zusammenfassung
Hintergrund
Die Stanzbiopsie zur pathologischen Diagnostik von Weichgewebstumoren wird bzgl. ihrer Spezifität kontrovers diskutiert. Wir haben die Spezifität der Methode bei unseren eigenen Patienten untersucht und den Einfluss einer Spezialisierung des durchführenden Chirurgen überprüft.
Patienten und Methode
Sechsundneunzig Patienten mit Stanzbiopsie und ggf. im Verlauf durchgeführter Resektion wurden eingeschlossen. Evaluiert wurden Spezifität, logistische Anforderungen sowie eventuelle Komplikationen der Methode. Ein besonderes Augenmerk lag auf dem Einfluss der Erfahrung des behandelnden chirurgischen Teams auf die Spezifität.
Ergebnisse
In 69,7 % der Fälle stimmte die Entität, in 75,0 % die Dignität und in 72,0 % das Grading überein. In der Gruppe der durch ein spezialisiertes Team biopsierten Patienten lag die Spezifität bzgl. der Entität bei 84,6 %, der Dignität bei 84,6 % und des Gradings bei 80 %. Bei der Entitätsbestimmung ergab sich hier ein signifikant höherer Wert für die Spezifität (p < 0,05).
Schlussfolgerung
Die perkutane Stanzbiopsie stellt aus unserer Sicht eine logistisch einfache, effiziente und komplikationsarme Methode in der Diagnostik von Weichgewebstumoren dar. Hierzu sollte die Überweisung des Patienten in ein spezialisiertes Zentrum erfolgen.
Abstract
Background
The role of percutaneous needle biopsy in the diagnostics of soft tissue tumors is controversially discussed. The specificity of this method has been examined in this study based on the collective of patients treated in our university hospital. Secondly, the influence of the specialization of the treating surgeon has been evaluated.
Patients and methods
This study included 96 patients who underwent percutaneous needle biopsy and, if necessary, surgical resection. The specificity, logistic requirements and possible complications of percutaneous biopsy were evaluated. Special attention was paid to the influence of specialization of the treating surgical team on the specificity of the method.
Results
The results of the biopsy were able to define the entity of the lesion correctly in 69.7 %, the dignity in 75.0 % and the grading in 72.0 % of the cases. In the group treated by a specialized team, the specificity of the method was 84.6 % concerning the entity of the lesion, 84.6 % concerning the dignity and 80 % concerning the grading. With regard to the entity the specificity was significantly increased (p < 0.05).
Conclusion
The findings show that percutaneous needle biopsy represents a logistically simple and efficient diagnostic method for soft tissue tumors which is rarely associated with complications. Subsequent treatment should be performed in a specialized centre.
