[Usefulness of bone gammagraphy versus tumor markers (PSA/PAP) in monitoring cancer of the prostate].

In this paper, data obtained through bone gammagraphia, prostatic specific antigen and prostatic acid phosphatase in 159 measurements carried out in 76 patients with treated prostate cancer, 41 locoregional and 35 metastatic, is compared. Sensitivity to detect progression was higher for PSA (89% in LR and 92% in M) versus bone GF (22% in LR an 83% in M) and PAP (11% in LR and 79% in M). The results indicate that it is possible to use bone gammagraphia optimizing its efficacy.
