Which endometrial pathologies need intraoperative frozen sections?

Area of Science:

• Gynecologic Oncology
• Pathology
• Surgical Diagnostics

Background:

• Endometrial cancer is the most common gynecologic malignancy.
• Endometrial sampling is a routine pre-operative procedure to rule out endometrial cancer.
• Accurate diagnosis of endometrial pathology is crucial for patient management.

Purpose of the Study:

• To evaluate the accuracy of endometrial sampling in diagnosing endometrial pathologies.
• To identify specific findings that warrant intra-operative frozen section analysis.

Main Methods:

• Retrospective study of 309 women undergoing endometrial sampling and hysterectomy between 2010-2012.
• Data collected from patient files and pathology archives.
• Analysis of endometrial sampling accuracy for malignancy detection.

Main Results:

• Endometrial sampling detected malignancy in 10 out of 17 cases (sensitivity 58.8%, specificity 100%).
• Missed malignancies occurred in 7 patients, including those with complex atypical hyperplasia and post-menopausal polyps.
• High negative (97.6%) and positive (100%) predictive values for cancer detection were observed.

Conclusions:

• Endometrial sampling is effective for diagnosing endometrial pathologies.
• Post-menopausal women with endometrial polyps and complex atypia hyperplasia have an increased risk of malignancy.
• Intra-operative frozen section confirmation is advised for these high-risk findings.
