Impact of Cribriform Pattern on Progression-Free Survival After Radical Prostatectomy in Gleason Score 8-10 Prostate...

Area of Science:

• Urology
• Oncology
• Pathology

Background:

• Cribriform pattern 4 (CP4) is known to negatively impact survival in non-high-risk prostate cancer (PC).
• The prognostic value of CP4 in high-risk PC remains unclear.

Purpose of the Study:

• To investigate the association between cribriform pattern 4 and progression-free survival (PFS) in patients with high-risk prostate cancer.
• To evaluate the prognostic significance of CP4 in the context of radical prostatectomy for high-risk PC.

Main Methods:

• Retrospective analysis of individual patient data from The Cancer Genome Atlas (TCGA) database.
• Inclusion of patients who underwent radical prostatectomy for high-risk prostate cancer (Gleason score 8-10).
• Statistical analysis to assess the relationship between CP4 presence and PFS, adjusted for covariates.

Main Results:

• The study included 135 patients, with CP4 identified in 66 (48.9%).
• Median follow-up duration was 45.93 months.
• The presence of CP4 was significantly associated with reduced PFS (subdistribution hazard ratio, 1.99; P=.045) after adjusting for other factors.

Conclusions:

• Cribriform pattern 4 is a significant adverse prognostic indicator in high-risk prostate cancer (Gleason 8-10).
• The findings suggest CP4 presence portends worse progression-free survival following radical prostatectomy.
• Further research is needed to clarify the role of CP4 in risk stratification and guiding post-operative management strategies for PC.
