[The role of bone scintigraphy and its value in the staging and follow up of prostatic carcinoma].

The role and value of bone scintigraphy in the staging and follow-up of prostatic cancer. Bone scintigraphy was performed in 100 patients with prostatic cancer at the time of histological diagnosis, and during 6 years follow-up in predefinied manner. The sensitivity of the method was enhanced by the results in the case of early M0-1 staging (the rate of the skeletal metastasis was 41% at the first seen). During the follow-up only 8 further cases of skeletal metastasis was observed. In most of the cases the skeletal metastasis was already disseminated at the first seen, the hot spots were located mainly at the pelvis and spine. In six cases "super bone scan" was observed. The conventional hormone therapy resulted in regression in 7 of the patients with skeletal metastasis. According to the authors' experiences the bone scintigraphy is indispensable at the diagnosis in the correct staging, and useful in the patient's follow-up.
