RESUMEN
OBJECTIVE: The addition of magnetic resonance imaging (MRI) to mammography for surveillance of women with BRCA mutations significantly increases sensitivity but lowers specificity. This study aimed to examine whether MRI surveillance, and particularly recall, is associated with increased anxiety, depression, or breast cancer worry/distress. METHODS: Women with BRCA mutations in an MRI surveillance study were invited to complete: Hospital Anxiety and Depression Scale (HADS), Lerman's Breast Cancer Worry Scale, Breast Cancer Worry Interference Scale, and a quality of life rating at 3 time points: 1-2 weeks before (T1), 4-6 weeks after (T2) and 6 months after their annual surveillance (T3). Repeated measures analyses were performed over the 3 time points for recalled and non-recalled women. RESULTS: 55 women (30 BRCA1, 25 BRCA2) completed study instruments at T1 and T2, and 48 at T3. Eighteen women (32%) were recalled for additional imaging. At T1, 27 women (49%) were above HADS threshold for "possible cases" for anxiety (score≥8). Recalled (but not non-recalled) women had a significant increase of HADS anxiety at T2 which dropped to below baseline by T3. No group differences were observed in terms of change over time in other quantitative psychological measures. CONCLUSIONS: While breast MRI surveillance did not have a detrimental psychological impact on women with a BRCA1 or BRCA2 mutation, recalling these very high-risk women for further imaging after a false positive MRI scan temporarily increased their global anxiety.

AIMS: In screening studies of women with BRCA mutations, magnetic resonance imaging (MRI) plus mammography has >90% sensitivity for detecting breast cancer, with negligible benefit from the addition of breast self-examination (BSE) or clinical breast examination (CBE). Yet CBE is still frequently recommended, and BSE is encouraged for these women. We sought to determine the attitudes of high-risk women toward CBE and BSE. METHODS: Between November 2005 and May 2006, 137 women with BRCA mutations participating in a screening study consisting of annual MRI and mammography plus semiannual CBE were asked to complete a mailed Likert-type questionnaire. RESULTS: Of the 94 (67%) respondents, mean age 47 (range 28-67), 94% strongly agreed or agreed that CBE was an important way to detect breast cancer, and almost all believed it provided an important connection to the healthcare team. Only 10% said it increased anxiety. Of the 71 (77%) who performed BSE at least occasionally, 53 thought that regular BSE gave them a sense of control over their own health. Of the 21(23%) who did not practice BSE at all, only 3 did not believe that BSE was helpful, and it made 9 more worried about breast cancer CONCLUSIONS: Although CBE adds little to cancer detection rates in women with BRCA mutations screened with MRI, the majority of these women considered CBE to be reassuring and an important means of connecting with the healthcare team. Compliance with BSE was only moderate, but it gave a significant proportion of women a greater sense of control.
