Eric Rupe, from George Washington University Medical Center, and colleagues evaluated the outcomes of BSGI-guided biopsy in women with suspicious BSGI findings. Thirty-eight women had 40 BSGI-guided biopsies between January 2011 and October 2013.
Of the 38 women with 40 suspicious BSGI findings not visible by mammography or ultrasound, BSGI-guided biopsy found eight cancers (20%); five were invasive and three were ductal carcinoma in situ. There were also six cases of atypia (15%) -- for a total of 14 (35%) cancer or high-risk lesions identified, Rupe's team wrote.
"When a lesion is visible by BSGI, and not by mammography or ultrasound, our findings support BSGI-guided biopsy as a reasonable and accurate approach to biopsy the lesion," Rupe and colleagues concluded. "Our results compare favorably to those reported for MR-guided biopsy."
