Legacy Good Samaritan Hospital Surgeons Find BSGI Effective in Determining Extent of Breast Cancer in Patients With Known Diagnosis

NEWPORT NEWS, Va., June 9 A group of surgeons from LegacyGood Samaritan Hospital (Portland, Oregon) have found Breast-Specific GammaImaging (BSGI) has a significant value in the pre-operative assessment for theextent of breast cancer in patients with known diagnosis. The findings werepresented at The Society of Black Academic Surgeons Annual meeting held inCleveland, Ohio.

BSGI is a molecular breast imaging technique used for the early detectionof breast cancer and in the differentiation of malignant and benign tumors. Itrelies on advanced gamma imaging technology and mammographic positioning tooptimize results. For this study BSGI was conducted with a commerciallyavailable high-resolution gamma camera, the Dilon 6800.

The study evaluated 138 patients with a cancer diagnosis. In this group,additional disease was found in a total of 11 percent of patients. Six percentwere in the same breast and 5 percent were in the opposite breast. Thisfinding is very similar to that of an MRI study conducted by Bilimoria fromNorthwestern University; however, BSGI provided a significantly lower falsepositive rate of 7 percent compared to 78 percent with the MRI study.

Member of the Legacy Good Samaritan Hospital group of surgeons, Dr. M.Zhou, concluded that BSGI parallels MRI in sensitivity in the preoperativesetting, demonstrates better specificity than MRI, and is less expensive thanMRI.
