Utility of bone scanning in detecting occult skeletal metastases from cervical carcinoma.

Bone scans were obtained in 100 patients with carcinoma of the cervix in order to search for occult skeletal metastases. Scans revealed metastases in 4 patients with advanced stages of disease, but the scans in 79 patients with Stage 0, I, or II disease were negative. The scans in 14 patients showed renal asymmetry; 11 of these had obstructive uropathy due to tumor invasion or radiation therapy. Bone scanning does not seem warranted as a screening test in asymptomatic patients with Stage 0, I, or II carcinoma. If the test is done, renal symmetry should be carefully evaluated.
