UroToday.com- In the August issue of Urology, Dr. Kang and associates from the SEARCH database report that Gleason score 7(4+3) CaP has a similar risk profile to Gleason (4+4). A Gleason cohort of 374 men was studied and included men with a Gleason score of 3+4, 4+3, or 4+4 or more. Clinical, pathologic, and biochemical outcomes were assessed in univariate and microvariate analysis.

A biopsy Gleason score of 4+3 was associated with higher risk disease than was 3+4 as noted by higher pathologic grade and more extracapsular extension (ECE) and seminal vesicle invasion (SVI). No significant differences were identified between Gleason score 4+3 and 4+4 or more in any clinicopathologic characteristic other than for higher grade pathologic tumors in the 4+4 cohort. While Gleason score 4+3 had increased odds of ECE and SVI, the 4+3 group did not differ in ECE, SVI, or positive surgical margins from the 4+4 cohort. During the follow-up period 37% experienced biochemical progression and Gleason score 4+3 were associated with an increased risk of progression relative to 3+4 but it was similar to 4+4. Furthermore, men with an RP Gleason score of 4+3 had an increased risk of progression relative to an RP Gleason score of 3+4, but it was similar to those with an RP score of 4+4. These data suggest that men with a biopsy Gleason score 4+3 should be counseled similar to those with a Gleason score 4+4, due to the risk of adverse pathologic outcomes and tumor progression.
