Abstract
The incidence of bone metastases in the initial extension assessment was low; consequently, they are not sought systematically. However, their presence radically changes the prognosis and the therapeutic management, raising the question of screening. The technetium-99Â m bone scintigraphy has limits, with many false-positive resulting the need for additional investigations. Defining the risk factors for bone metastases would improve screening. Two questions remain: what factors are involved? The bone pain and the hypercalcemia must be analyzed with a larger number of cases, but they seem to be nonspecific. The node involvement stage could be a more reliable parameter, in particular in cases of jugular vein invasion; what method should be used? In the future, the PET scan could be the key procedure not only in the locoregional extension assessment, but also for general extensions, in a single procedure investigating the whole body.
