Abstract
BACKGROUND:
We sought to determine the number of patients with known breast cancer who were found to have an additional, mammographically occult lesion detected on breast-specific gamma imaging (BSGI).
METHODS:
An institutional review board-approved review of all patients who underwent BSGI at Beth Israel Medical Center from 2006 to 2008 was performed.
RESULTS:
A total of 82 patients underwent BSGI for newly diagnosed breast cancer. Of these, 18 had an additional abnormality, and 17 were biopsied. There were 4 cases of invasive ductal carcinoma, 1 invasive lobular carcinoma, 1 ductal carcinoma in situ, 1 lobular carcinoma in situ, 2 papillomas, and 8 benign biopsies. One patient proceeded directly to mastectomy and an area of ductal carcinoma in situ was found, corresponding to the BSGI.
CONCLUSIONS:
In our study group, 22% of patients had a surgical change in management based on BSGI findings. BSGI detected additional carcinoma in 9%. BSGI plays an important role in the clinical management of patients with known breast cancer.
