title: [The usefulness of early whole body bone scintigraphy in the detection of bone metastasis from prostatic cancer].
abstract: Early whole body bone scintigraphy was performed on 25 patients with prostatic cancer (15 cases with bone metastases and 10 cases without bone metastasis) to obtain anterior and posterior whole body images five minutes after administration of 99mTc-HMDP. The results were compared with the findings of routine bone scintigraphy after three hours, and the usefulness of the above method for the diagnosis of bone metastasis from prostatic cancer was evaluated. In cases in which increased activity was found in the upper and lower lumbar vertebrae by routine bone scintigraphy but no abnormality was seen by early whole body bone scintigraphy, senile degenerative bone changes such as spondylosis deformans were observed by bone radiography. In cases with multiple bone metastases, abnormal multiple accumulations were found by both early whole body bone scintigraphy and routine bone scintigraphy. In addition, in cases showing super bone scan, high accumulation in the skeletal system had already been detected by early whole body bone scintigraphy. When the courses before and after treatment in nine cases of multiple bone metastases were passaged from the results of early whole body bone scintigraphy and from changes in tumor markers (prostatic specific antigen, gamma-semino protein and prostatic acid phosphatase), increased activity and the appearance of new hot spots as well as an increase in tumor markers were detected by early whole body scintigraphy in three of the four advanced cases, whereas decreased accumulations and a decrease in and normalization of tumor markers were observed in five improved cases.
