Survey of 1725 Bone Scans in Patients with Malignant Disease with Particular Emphasis on Carcinoma of the Breast

Abstract

1725 bone scans, done for evaluation of metastatic involvement from malignant neoplasms, were reviewed. The fraction of positive scans (multiple lesions in the bone scan) was 34% of the patients with different malignancies. In 251 patients (12%) a single bone lesion was detected and 114 of these patients were followed-up and re-scanned once or twice within 1 to 4 years. 39 of the 93 patients with solitary bone lesion who on follow-up developed multiple lesions had carcinoma of the breast as the primary.
