111 Indium‐Bleomycin ( 111 In‐Blm), a new radiopharmaceutical, was administered intravenously to 37 patients with benign and malignant breast lesions. Early and delayed images of both the breasts and axillae were made, and results were correlated with physical examination, histopathology of the excised lesion, mammography, and thermography. In 18 patients with malignant disease, clinical examination of the breast and axilla correlated with histopathology in 78 and 54% of the cases, respectively. Images of the breast were accurate (true positives) in 83% of the cases. Images of the axilla were accurate in 62% of the cases. Mammography was correct and suggested malignancy in 88%, and thermography in 73% of the cases. In 19 patients with benign breast lesions, clinical examination of the breast and axilla correlated with histopathology in 68 and 95% of the cases, respectively. Scans of the breast and axilla were correct (true negative) 79 and 95% of the time, respectively. Mammography was correct, and suggested benignancy, in 53% and thermography in 25% of the cases. Imaging of the breasts using 111 In‐Blm appears to be as accurate as physical examination and mammography for palpable benign and malignant breast tumors. It is less accurate than mammography for microscopic malignancies. Axillary imaging does not appear to be worthwhile because many axillary metastases are too small for detection with current nuclear medicine instrumentation.
