Diagnostic accuracy of prehysterectomy curettage in determining tumor type and grade in patients with endometrial cancer.

Objectives: We sought to determine the reliability of tumor typing and grading at the prehysterectomy curettage biopsy in patients with endometrial carcinoma. We also wanted to evaluate the overall rate of false-negative diagnosis in the detection of the disease.

Methods: The final pathologic reports of 263 patients whose diagnosis was endometrial carcinoma were compared with their prehysterectomy curettage reports.
