Rendimiento de la biopsia por aspirado en el diagnóstico del carcinoma de endometrio

Abstract

Objective: Analyze pre and post operative histological concordance of endometrial cancer (EC) diagnosed by Cornier biopsy cannula. Methods: 82 patients under going out patient biopsy aspirate blindly with EC in the hysterectomy specimen. We study the type and histological grade accuracy by two groups for each analysis: EC endometrioid/non-endometrioid and low/high grade. Results: The sensitivity for detecting malignancy was 100[%]. The histological type agreement was 94[%] (96.7[%] for the endometrioid type and 85[%] for non-endometrioid type). The histological grade accuracy was 90.2[%] (94.3[%] in low-grade tumors and 82.7[%] in high grade) with a rate of under estimation of tumor grade of 6[%]. Conclusions: Cornier aspiration biopsy is safe in the diagnosis of EC. Grade and histological type accuracy between preoperative biopsy and surgical specimen is high. The most discordant is EC G3 endometrioid type.
