Low-grade appendiceal mucinous neoplasm encountered during risk-reducing salpingo-oophorectomy: A case of laparoscopic surgery.

Low-grade appendiceal mucinous neoplasm (LAMN) is a rare epithelial malignancy of the appendix. If it perforates the abdominal cavity, it can cause a serious clinical syndrome called pseudomyxoma peritonei. In the present case, we laparoscopically removed a LAMN encountered during risk-reducing salpingo-oophorectomy (RRSO).

Impact of lower co-payments on risk-reducing salpingo-oophorectomy and BRCA testing in Japan.

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 BRCA testing were started in Japan. We investigated the impact of insurance coverage on the number of RRSO and BRCA tests 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.

Significance of positive peritoneal cytology for recurrence and survival in patients with endometrial cancer.

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.

Possible significance of degeneration and decreased expression of progesterone receptor in postmenopausal uterine leiomyoma.

Background: The growth of uterine leiomyomas is dependent on the levels of sex steroid hormones, and they usually shrink after menopause. However, there are cases in which leiomyomas continue to grow and/or surgery is required after menopause. In addition to estrogen, progesterone has recently been implicated in leiomyoma enlargement, but its relevance to postmenopausal leiomyoma remains unknown.

Total Laparoscopic Hysterectomy for Anterior Cervical Myoma: Possible Significance of Presurgical Assessment by Magnetic Resonance Imaging.

Hysterectomy for large uterine anterior cervical myoma is a challenging surgical procedure. We summarize our experience in the management of large uterine anterior cervical myoma. Three patients underwent hysterectomy for uterine anterior cervical myoma with similar sizes and different positions treated by laparoscopic surgery.
