Unifocal bone findings by scintigraphy. Clinical significance in patients with known primary cancer.
Preliminary findings suggest that in patients with known primary cancer, a large percentage of unifocal lesions seen on radionuclide bone scans are not metastatic. In a survey of radionuclide bone studies done on 861 consecutive patients, 30 patients with known primary cancer had solitary lesions. Adequate follow-up information was available on 21 of these 30 patients. In only four did the lesions prove to be caused by metastatic malignancy.
