Analysis of pre- and postoperative pathological findings in endometrial cancer
Objective: The study was conducted to compare pre- and postoperative histopathological findings in women with endometrial cancer as well as to evaluate the diagnostic value of dilatation and curettage procedure in patients with endometrial pathology. Material and method: We evaluated histopathological findings of patients diagnosed with endometrial cancer during postoperative histopathological examination. All patients were treated in the Clinical Department of Gynecologic Oncology, Nicolaus Copernicus Memorial Specialist Hospital in Łódź between 2010 and 2015. A comparison of postoperative and preoperative findings based on specimens obtained by dilatation and curettage was performed. The vast majority of preoperative diagnoses and pathological assessments were performed outside the Clinical Department of Gynecologic Oncology in Łódź. A total of 115 patients were included in the study. Results: In the analyzed group, the type of cancer in preoperative examination matched the postoperative diagnosis in 86.96%. The compatibility of grading (assessed for endometrioid endometrial cancer) reached only 53.9%. Endometrioid endometrial cancer was the most common cancer in the examined set of curettage specimens. Histopathological compliance was 30.3% for G1 endometrioid endometrial cancer, 73.1% for G2 endometrioid cancer and 37.5% for G3 endometrioid cancer. Preoperative grading was overestimated in 10.75% and underestimated in 30.11% of cases. A shift from G1 to G2 was most commonly reported. Conclusions: Preoperative consultation with pathologists with extensive oncology experience before making medical decisions as well as treatment and postoperative assessment in medical centers experienced in gynecologic oncology seem to be crucial in predicting outcomes in this group of patients.
