Abstract
Bone scintigraphy was performed on 163 new cases of nasopharyngeal carcinoma without clinical evidence of distant metastases. Among the 10 abnormal bone scans one patient had radiographic skeletal metastases corresponding to the areas of increased tracer uptake. Two patients with abnormal bone scans subsequently developed radiographic metastases at the site of abnormal tracer uptake. The detection rate of asymptomatic skeletal metastases on presentation was thus 1.8% (3/163), and the predictive value of an abnormal scan for metastases 30% (3/10). Bone scintigraphy is not justified as a routine staging investigation for nasopharyngeal carcinoma, although it can be considered for a subset of patients considered at high risk of distant metastases.
