Peritoneal cancer arising after total abdominal hysterectomy and bilateral salpingo-oophorectomy for cervical cancer in a patient with right breast cancer and germline mutation of BRCA1 gene: a case report and literature review

Abstract

Primary peritoneal carcinoma is usually advanced at diagnosis and curability is low unless the patient has a small tumor burden. Peritoneal carcinoma can occur in association with hereditary breast and ovarian cancer syndrome, which is thought to account for 5–6% of all breast cancer. Mutations of two breast cancer susceptibility genes, BRCA1 and BRCA2, are responsible for hereditary breast and ovarian cancer. Women with BRCA1/2 mutations often undergo risk-reducing salpingo-oophorectomy (RRSO) to prevent both ovarian and breast cancer. However, peritoneal carcinoma has been reported to develop after RRSO in patients with BRCA1/2 mutations. We experienced a patient with peritoneal carcinoma and inguinal lymph node metastasis after surgical resection of breast cancer and subsequent RRSO. This report describes the first case of peritoneal carcinoma arising after RRSO in a Japanese patient with BRCA1 mutation, including a review of the literature on peritoneal carcinoma associated with BRCA1/2 mutation.
