[The diagnosis of prostate cancer dissemination]

Prostate cancer preferentially metastasizes to regional lymph nodes and bone. The incidence of dissemination has been reduced over the last years mainly due to the compost use of PSA. For this reason, the indication of complementary diagnostic tests has evolved with the aim of improving the diagnostic yield. Some of these techniques are currently under evaluation and may contribute in the close future to change the study of dissemination in the clinical practice. CT scan or MRI are the standard imaging studies for lymph node dissemination, whereas bone scan continues to be the routine test for bone dissemination.
