Abstract

Aim: This study aims to examine the association between malignant peritoneal cytology and prognosis in women with endometrial cancer. Methods: We retrospectively analyzed the records of patients with endometrial cancer who underwent surgery with intraoperative peritoneal cytology at our hospital between January 1988 and December 2012. All results were reclassified according to the 2009 International Federation of Gynecology and Obstetrics (FIGO) system, and the relation between intraoperative peritoneal cytology results and recurrence and prognosis was examined. Results: Of the 908 patients analyzed, 205 (22.6%) had positive peritoneal cytology. Patients with positive peritoneal cytology had significantly lower rates of recurrence‐free survival (RFS) and overall survival (OS) than those in the negative cytology group (both p < 0.001). Subgroup analysis of patients with FIGO stage I/II showed significantly lower RFS in the positive‐cytology group (p = 0.005), but there was no significant difference in OS (p = 0.637). In the patients with FIGO stage III/IV or patients classified as "high risk," the RFS and OS were significantly lower in the positive‐cytology group (both p < 0.001). Cox regression analysis identified positive peritoneal cytology as a significant predictor of recurrence in patients with FIGO stage I/II disease. Conclusions: Patients with positive peritoneal cytology for endometrial cancer have a high risk of recurrence, regardless of histopathologic type or FIGO stage. Peritoneal cytology has already been removed from the 2009 FIGO classification of endometrial cancer, but it may deserve reconsideration. [ABSTRACT FROM AUTHOR]

Abstract

Background: In April 2020, insurance coverage for risk-reducing salpingo-oophorectomy (RRSO) for breast cancer patients with hereditary breast and ovarian cancer (HBOC) syndrome and BRCAtesting were started in Japan. We investigated the impact of insurance coverage on the number of RRSO and BRCAtests performed. Methods: The subjects were 370 breast cancer patients and 23 of their relatives who received genetic counseling at our institution between April 2014 and December 2021. Finally, 349 patients and 15 relatives were analyzed. We retrospectively compared the number of BRCAtests, RRSO, insurance status, and co-payment of medical expenses before and after insurance coverage based on medical records. Results: In the 6-year pre-coverage period, 226 patients (mean: 37/year) received genetic counseling and 106 (17/year) received BRCAtesting. In the 21-month post-coverage period, 161 patients (92/year) received genetic counseling and 127 (72/year) received BRCAtesting. The rate of testing/counseling significantly increased in the post-coverage period (46.9% vs. 78.8%; p&lt; .001). The number of patients who were diagnosed with HBOC were 24 (4/year) and 18 (10/year) and RRSO was performed for 7 (1/year) and 11 (6/year) patients in the pre- and post-coverage periods, respectively. The rate of RRSO/HBOC was significantly increased in the post-coverage period (29.1% vs. 61.1%; p= 0.039). RRSO patients' co-payment rates decreased from 64% to 25% pre- and post-coverage. Conclusions: Our findings suggest that decreased co-payments were the primary reason for these increases. Insurance coverage is an important factor when promoting preventive medical services such as RRSO.
