The impact of surgical downgrading on prostate cancer recurrence: systematic review and analysis of a multiethnic population.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo perform a systematic review and a retrospective cohort analysis evaluating the rates of surgical downgrading of prostate cancer (PCa) from biopsy (PBx) to radical prostatectomy (RP), and their association with biochemical recurrence (BCR) in a multiethnic population.
methodsA systematic review of PubMed and other databases was performed. We included retrospective studies evaluating the relationship between surgical downgrading and BCR-free survival. Data regarding Gleason score (GL) downgrading were abstracted from the articles and categorized as follows: GL8-10 to GL7, GL7 to GL6, and GL 7(4 + 3) to GL7(3 + 4). We also performed a retrospective cohort review of patients who underwent RP at our institution from 2005 through 2020. Kaplan-Meier survival analysis and Cox proportional hazards models were used to compare BCR among downgraded versus non-downgraded men.
resultsSystematic review yielded 137 abstracts; of these, 36 full-texts were reviewed, 8 of which were included in our systematic review. Despite substantial variability, all showed that GL at RP is one of the most important factors of BCR-free survival. A total of 1,484 men with PCa were analyzed from our institution. On multivariate analysis, GL7 to GL6 downgrading (HR = 0.50, p = 0.022) and GL8-10 to GL7 downgrading (HR = 0.42, p = 0.011) were associated with reduced risk of BCR when compared to men with GL7 and GL8-10 concordance, respectively. However, GL7(4 + 3) to GL7(3 + 4) downgrading was not significantly associated with reduced BCR (HR = 0.56, p = 0.12), when compared to GL7(4 + 3) concordance, although HR was similar.
conclusionSurgical downgrading at RP was associated with a reduced risk of BCR compared to GL concordant disease, and these findings have been validated within our multiethnic population. Pathologic downgrading at the time of RP may be a more useful predictor of subsequent BCR in comparison to that associated with GL concordant pathology.
