한국인 유전성 유방암 연구 이후 국내 유전성 유방암 진료 패턴의 변화

Abstract

Purpose: The objective of this study was to evaluate the change in the practice patterns for managing hereditary breast and ovarian cancer (HBOC) among Korean physicians after the Korean Hereditary Breast Cancer (KOHBRA) study. Methods: The first survey was performed from July to August 2007, at the initiation of the KOHBRA study, and the follow-up survey was conducted from July to December 2009. Members of the Korean Breast Cancer Society were invited to participate in the study by e-mail. The 2009 survey was conducted with a self-administered questionnaire concerning HBOC management and was identical to the previous questionnaire. Results: According to the 2009 survey, most physicians (60.0%) tended to draw a pedigree (48.0% in 2007 survey). The rate of genetic test recommendations for patients at risk for HBOC was higher in the 2009 survey (84.0%) than that in the 2007 survey (64.0%). Physicians tended to select a BRCA genetic testing candidate more appropriately than in the previous survey (42.4% answered right in 2007 survey; 74.4% in 2009 survey). Fifteen of 25 participants (60.0%) provided genetic counseling before their patients underwent a genetic test, which was higher than that (40.0%) in the 2007 survey. According to the 2009 survey, half of the genetic counseling was being conducted by KOHBRA study research nurses; whereas most of the genetic counseling was conducted by physicians in 2007. Conclusion: The KOHBRA study has played an important role in the appropriate selection of candidates for genetic testing. However, more effort should be placed on improving the pre-test genetic counseling rate.
