Comparative study between prostatic carcinoma G1-G3 and Gleason grading systems.
The need of an accurate and prognostically valuable method for grading the prostatic carcinoma resulted in, in the last decades, a large number of systems, none of them succeeding in being unanimously accepted by the pathologists family. The authors selected and reassessed using Gleason system a group of 221 cases with prostatic adenocarcinoma previously diagnosed using a combined G1-G3 system. The results were converted from Gleason system to G1-G3 system and then compared with the initial diagnostics. The group was divided, following the type of surgical procedure used for drawing the tissue, into three groups: transvesical prostatectomies (TVP), transurethral resections (TUR) and needle biopsies (B). The concordance between the two systems was good, even the number of TUR and B specimens was significant (85% of the studied group) showing that any of them can be successfully used in current practice, depending only on pathologist's experience.
