Abstract

Purpose

The aim of this study is to assess the precision of the Gleason score (GS) obtained through cognitive fusion-targeted biopsy (COG-TB) in comparison to transrectal ultrasonography-guided systematic biopsy (TRUS-SB), and to identify factors that can predict Gleason score upgrading (GSU) in a cohort of Chinese patients.

Methods

A final enrollment of 245 patients was recorded. Between 2020 and 2022, 132 patients underwent TRUS-SB, and 113 patients underwent COG-TB. The Chi-square test was performed to analyze the variation in downgrading, concordance, and upgrading between TRUS-SB and COG-TB. Multivariable analyses were performed to seek factors predicting Gleason score upgrading. Finally, a model which utilizes multivariable logistic regression was developed to predict the likelihood of GSU.

Results

The concordance for TRUS-SB and COG-TB were 42.4% and 65.5%, respectively. TRUS-SB and COG-TB exhibited notable disparities in downgrading, concordance, and upgrading. Age, prostate volume, body mass index (BMI), and the biopsy modality were significant predictive factors.

Conclusion

COG-TB can significantly increase concordance with final histopathology. Age, prostate volume, BMI, and the biopsy modality were predictive factors of GSU.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
