The use of bone and brain scans as screening procedures in patients with malignant lesions

A retrospective study to determine the value of bone and brain scans was performed in preoperative patients with melanoma, sarcoma, cancer of the head and neck and carcinoma of the pelvis. No occult metastases were identified in 170 patients in whom brain scan was performed. On late follow-up data, eight patients had neurologic symptoms develop and had brain metastases identified on scan. Of 223 bone scans performed, only one distant metastatic lesion was identified. It is, therefore, suggested that, in these types of patients, bone and brain scans be reserved for those with symptoms referable to the neurologic or skeletal systems.
