Background: This study aimed to identify the clinical background and treatment outcomes of risk-reducing salpingo-oophorectomy (RRSO) in Japan for women with hereditary breast and ovarian cancer (HBOC). Methods: In the present retrospective observational study, we examined the Japanese HBOC Consortium's (JHC) database. This database contains 11,711 probands who received BRCA genetic testing, or their relatives, with any cancer in 2433 pedigrees. This study was supported by the registration committee of the JHC. Results: We analyzed 488 individuals diagnosed with HBOC, of which 153 (31.4%) underwent RRSO. Of the latter patients, 88 carried BRCA1 mutation (B1); 62 carried BRCA2 mutation (B2); and 3 carried both mutations. During a mean follow-up period of 2.6 years (range 0–12.6), one patient developed a primary peritoneal cancer (PPC). Clinical background comparison for individuals who underwent RRSO vs. those > 45 years of age who did not undergo RRSO revealed that significant factors were represented by B1 (p < 0.0001); child bearing (p < 0.00001); and breast cancer history (p < 0.01). However, family history of ovarian cancer and menopause status were not significantly different. Conclusion: Over 30% HBOC's in Japan underwent RRSO. In Japan, individuals with breast cancer history and B1 generally underwent RRSO, whereas those who did not bear a child mostly avoided RRSO. [ABSTRACT FROM AUTHOR] |
