ASBS: Value of <12-Month Interval Imaging Examined
Imaging performed less than 12 months post benign biopsy has low yield for breast cancer detection
THURSDAY, May 2 (HealthDay News) -- For patients with benign radiologic-pathologic concordant minimally invasive breast biopsy, interval imaging performed after less than 12 months has a low yield and high cost for detection of breast cancer, according to research presented at the annual meeting of the American Society for Breast Surgeons, held from May 1 to 5 in Chicago.
Demitra Manjoros, M.D., from Bryn Mawr Hospital in Pennsylvania, and colleagues conducted a retrospective chart review involving 689 patients who underwent image-guided breast biopsy at the Comprehensive Breast Center between January and December 2010. Interval imaging was obtained less than 12 months after benign biopsy for 337 radiologic-pathologic concordant patients.
The researchers found that, for 95.9 percent of the concordant patients, interval imaging at less than 12 months was benign with Breast Imaging-Reporting and Data System (BI-RADS) 1, 2, or 3. A further 1.2 percent (two patients) received BI-RADS 0 and were deemed benign after further imaging. BI-RADS 4 was identified in five patients (3.0 percent), three at the original biopsy site and two at a distant site. Only one breast cancer was identified, representing 0.6 percent of all those concordant patients who underwent interval imaging. Detecting a missed cancer with interval imaging following benign radiologic-pathologic concordant minimally invasive biopsy cost an estimated $192,745.
"Interval imaging performed less than 12 months after benign radiologic-pathologic concordant breast biopsy had a low yield for the detection of breast cancer (0.6 percent) and resulted in increased health care costs," the authors write. "These data support the policy for discontinuation of interval imaging less than 12 months after benign radiologic-pathologic concordant biopsy."
