Background: Frozen section (FS) has a valuable role in the diagnosis of ovarian tumors. It is considered a pivotal point in guiding the surgical therapy, particularly in premenopausal women. In postmenopausal women, it may be required as well to avoid unnecessary surgical staging in benign ovarian tumors. Aim: This study aims to evaluate the accuracy of intraoperative frozen section in ovarian neoplasms in postmenopausal women. Materials and Methods: A retrospective analysis was done for intraoperative FS for suspected ovarian neoplasms. The study was conducted in Oncology Center, Mansoura University from March 2008 to December 2014. The frozen and paraffin section reports were compared, and overall accuracy, sensitivity, specificity, positive and negative predictive values were determined. Results: The study included 105 patients and the overall accuracy of FS in determining malignancy was 81.7%. The sensitivity for malignant tumors was 75.32% with specificity of 100%. For benign tumors, the sensitivity and specificity were 100% and 93%, respectively. Borderline tumors had the lowest sensitivity of 100% with specificity of 95.19%. Conclusion: The present study concurs that frozen section is an accurate test for diagnosis of benign and malignant tumors in postmenopausal women thus determining the extent of surgery done for them. On the other hand, accuracy rates for borderline tumors are low.

Introduction: Nowadays the more accepted surgical option for treating early breast cancer is breast conserving surgery. The main challenge in this type of surgery is to get free safety margins without need of second surgical operation, so many breast surgeons have started to depend on intraoperative frozen sections to ensure free safety margins. Aim of work: To assess our policy that we prefer to depend on intraoperative frozen section analysis to get free safety margin in breast conserving surgery from the 1st surgery, and its oncologic outcome. Patients and Methods: This is a retrospective study conducted in Oncology Center—Mansoura University (OCMU), where the data of 219 patients with breast cancer, who were managed by breast conserving surgery with intraoperative frozen section analysis of the safety margins, was analyzed. Results: The intraoperative frozen section analysis of safety margin was negative from the start in 183 (83.6%) patients, while it was positive in 36 patients (16.4%). Intraoperative decision of margin re-excision was applied for 29 patients (13.2%) in order to reach negative margin, modified radical mastectomy was offered for 4 patients (1.8%), while nipple sparing mastectomy with immediate breast reconstruction using latissimus dorsi flap was offered for 3 patients (1.4%). The postoperative paraffin results were typical with intraoperative frozen section analysis results in 216 patients (98.6%) and different results were obtained in only 3 patients (1.4%) who were managed by modified radical mastectomy in a second operation. Only 4 patients had local recurrence (1.8%) during the period of follow-up duration which was ranged from 1 to 86 months with mean ± SD (22.3 ± 14.1). Conclusion: The intraoperative frozen section analysis of safety margins in breast conserving surgery has very high-rate typical results with the paraffin section analysis and it is very helpful in decreasing the rate of second surgical operation in cases of infiltrated m
