title: [Intraprostatic spread of prostatic carcinoma: stereographic representation based on ultrasonography and biopsy findings].
abstract: The aim of this study is to identify and evaluate a scheme of graphic representation of the prostate, that allows the reconstruction of cancer diffusion based on ultrasound findings and on histological biopsy findings. A graphical representation of the prostate using transversal and longitudinal sections is represented by the US-operator, who write severy single performed biopsies (site, directions, and angle) and draws the US relieves. Biopsy specimens are separately prepared on a paper-support and marked at one extremity with china ink. The histopathological examination on every single specimen allows to identify the tumor extent, Gleason grading and the percentage occupied by the neoplasia. Were performed 50 transrectal echo-guided mapping biopsies. Comparing biopsy results with the pathological analysis on 13 whole-mount radical prostatectomy: pathological stage was predicted in 6 of 7 cases, Gleason grading was predicted in 85% of cases. In 5 cases in which the core biopsy histological analysis showed only atypical glands suspicious for cancer it has been possible to repeat new biopsies in the same site of the gland. Tumor was this time diagnosed in 3 of 5 cases (60%). The proposed approach can be useful to reduce variables linked to operator, technique, and single clinical situation, but it needs an employment on a higher number of cases and a verification on more surgical specimens. The scheme proposed has been of easy complication and immediate interpretation by clinicians and pathologists.
