Correlation between extent of metastatic lesions in whole body bone scintigraphy of patients with prostatic cancer and prostatic acid phosphatase in serum with Eiken PAP RIA kit.

The whole body bone scintigraphy of 13 patients whose prostatic cancer were histologically confirmed, was processed in four colors, and the bone metastases were quantitatively estimated. On the basis of this estimation, the extent of bone metastases was classified into 4 divisions (grades 0, 1, 2 and 3). And then, the correlation between the extent of bone metastases and prostatic acid phosphatase, acid phosphatase, and alkali phosphatase levels in serum were investigated.
