[Basic features of the ISUP prostate carcinoma Gleason grading system: a preliminary analysis].

[Article in Chinese]

Abstract

OBJECTIVE:

To explore the basic features of the prostate carcinoma Gleason grading system of the International Society of Urological Pathology (ISUP).

METHODS:

We analyzed the means and proportions of the Gleason score (GS), primary grade (PG), secondary grade (SG) and third grade (TG) of 667 cases of prostate carcinoma.

RESULTS:

The means of GS, PG, SG and TG were 7.06 +/- 1.10, 3.53 +/- 0.66, 3.53 +/- 0.72 and 4.30 +/- 0.96, respectively. The cases with GS 5, 6, 7, 8, 9 and 10 accounted for 0.4% (3/677), 37.2% (252/677), 34.4% (233/677), 13.7% (93/677), 12.0% (81/677) and 2.2% (15/677), respectively; those with GS < or = 6 and > or = 7 constituted 37.7% (255/677) and 62.3% (422/677); those with GS3 + 3, 4 + 3 and 3 + 4 made up 37.2% (252/677), 19.2% (130/677) and 15.2% (103/677); and the TG cases held 10.3% (70/677), including 30.0% (21/70) of grade 3, 10% (7/70) of grade 4 and 60.0% (42/70) of grade 5.

CONCLUSION:

Our study showed a high proportion of GS, a low proportion of GS < or = 6, and a high proportion of GS > or = 7 in the ISUP prostate carcinoma Gleason grading system. TG of GS needs to be further understood.
