BRCA mutations: An Appalachian experience.

20111 Background: BRCA1 and 2 mutations are rare in general population and women with these mutations confer a significantly increased risk of invasive breast and ovarian cancer (65% to 85%, and 15% to 65% cumulative lifetime risk, respectively). A few of these are variant mutations also known as Variant of unknown significance (VUS).,Observational study of 155 patients who presented to MBRCC, WVU for genetic counseling between November 2001 and March 2005. Patients underwent genetic testing after detailed genetic counseling. Clinical data, such as patient's age, ethnic origin, follow up period, Myriad risk of mutation, clinical outcome i.e., Mastectomy versus Bilateral Salpingo-oophorectomy versus Surveillance, total numbers of patients screened, tested and reason for not testing, and other data, were available for statistical analysis.,In out patient population who underwent genetic counseling, 46% (71 out of 155) underwent genetic testing. A large number of patients (54%; 84 out of 155) who underwent genetic counseling could not undergo the genetic testing. Total number of patients not genetically tested were 84, out of which, 27 were low risk, 35 had insurance denial, 7 were not interested, 14 were awaiting results or insurance approval and 1 was deceased. 27 out of 71 patients (38%) who underwent genetic testing were positive for a mutation. Among these patients (n = 27), 8 had BRCA 1; 3 had BRCA1 VUS; 7 had BRCA 2 and 9 had BRCA2 VUS. The average age for patients who had a genetic mutation was 42 years. The most prevalent genetic mutation in our study population was BRCA2 VUS (33%; 9 out of 27) followed by BRCA 1 mutation (29%; 8 out of 27). 11 out of 27 (40%) who had a mutation underwent mastectomy. 13 out of 27 patients (48%) who had a mutation underwent bilateral salpingo-oophorectomy. 7 out of 27 patients (26%) who had a mutation underwent total abdominal hysterectomy. 4 out of 27 patients (15%) who had a germline mutation were lost to followup.,We report the prevalence and the clinical outcomes in patients with BRCA mutations in the state of West Virginia, which is comparable to the national database. High number of patients could not undergo genetic testing because of insurance denial. No significant financial relationships to disclose.
