Abstract
- The nuclear bone scan is a highly sensitive means of detecting skeletal metastases in patients with prostatic cancer. The results of bone scan with technetium 99m-labeled methylene diphosphonate in 61 patients with biopsy-proven primary prostatic cancer demonstrated bone metastases in 60.7% of cases. The addition of bone scanning to radiographic survey increased the detection rate of bone metastasis by 45.2% and only 1 patient had abnormal roentgenograms but normal scans, a yield of 5.3% false-negative scans. Of those with proved bone metastases by bone scan with radiography, 44.4% had no bone pain, 55.6% had normal acid phosphatase level and 3l.2% had normal alkaline phosphatase levels. Of those without bone metastases by bone scan with radiography, 4.3% had bone pain, 9.1% had elevated acid phosphatase levels and 9.1% had elevated alkaline phosphatase levels.
