Review of 1,441 bone scans performed on 242 breast cancer patients without known skeletal metastases identified 239 scans with new abnormalities. Findings on 54 of these 239 scans (23%) represented bone metastases. The proportion of scans reflecting metastases, grouped by the number of new abnormalities, was: (1) 20/182 (11%); (2) 9/26 (35%); (3) 4/9 (45%); (4) 1/2 (50%); greater than or equal to 5-20/20 (100%). When metastatic disease presented as a bone scan with 1-4 new abnormalities, the spine was the most common site of involvement (18 of 34 (53%)), followed by the skull (5/34; 15%), extremities and sternum (each 4/34; 12%). Rib lesions were the most common new findings on scans with less than 5 new abnormalities (seen on 76 of 219 scans (35%)) but only infrequently represented metastases (n = 2). Considering as indicative of malignancy only, those bone scans which demonstrated either (a) greater than or equal to 5 new abnormalities, (b) initial radiographic correlation suggestive of metastases, or (c) thoracic spine lesions with normal correlative radiographs, the presence of skeletal metastatic disease could be predicted with a sensitivity of 0.80 and a specificity of 0.94.
