Abstract
The bone scan in patients with prostate cancer remains to be the most sensitive method to assess the bone metastasis. But it is nonspecific and shows similar finding in either beign or malignant disease. Bone mineral densitometry allows for the
quantification of total body bone mass. So we evaluated the efficacy of the measurement of the bone mieral density with dualenergy X-ray absorptiometry in patients with prostate cancer who had showed hot spot on the bone scan. Of the 15 patients
7
cases
(47%) showed increased bone mineral density. To evaluate the efficacy of bone mineral densitometry, we analyse the 11 patients whose bone scan show hot spot on lumbar spine. Among them 2 cases (18%) show osteoblastic finding on the bone x-ray,
but
5
cases (45%) show increased density and 2 cases show decreased density on the bone mineral densitometry.
These results show that the bone mineral densitometry is more valuable than bone x-ray in the detection of abnormal bone density. Therefore we suggest that bone mineral densitometry can be used as a helpful method of bone scan to detect the
metastatic
bone lesion in the advanced prostatic cancer.
