Prognostic significance of perineural invasion and lymphovascular invasion following robot-assisted radical prostatectomy with negative surgical margins: a retrospective study from a high-volume center.

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
purposePerineural invasion (PNI) and lymphovascular invasion (LVI) represent tumor escape mechanisms at radical prostatectomy (RP). We assessed their prognostic significance for biochemical recurrence (BCR) following complete resection.
methodsWe analyzed 10,471 men with negative surgical margins after RP, stratified into three groups based on pathological PNI and LVI status: Group 1 (PNI-/LVI-, n = 1,925), Group 2 (PNI+/LVI-, n = 7,849), and Group 3 (LVI+, n = 697; 14 with PNI-/LVI + and 683 with PNI+/LVI+). The cumulative probability of BCR (PSA > 0.2 ng/mL after initial undetectable level), cancer-specific mortality, and all-cause mortality were compared using Kaplan-Meier curves and log-rank tests. Multivariable Cox regression adjusted for age, race, comorbidity, PSA at biopsy, final grade group, pathological T and N stage, and tumor diameter.
resultsThe median follow-up was 60 months (IQR: 18-108). Pathological N1 disease was more frequent in Group 3 (5.7%) than in Group 1 (0.1%) and Group 2 (0.3%). Compared with Group 1, the unadjusted hazard ratios (HRs) for BCR were 6.07 (95% CI: 4.30-8.56) in Group 2 and 23.4 (95% CI: 16.3-33.6) in Group 3; adjusted HRs were 2.51 (95% CI: 1.76-3.58) and 3.79 (95% CI: 2.55-5.53), respectively. Mortality outcomes were comparable across groups, both before and after the adjustment.
conclusionOur study demonstrated that the combination of PNI and LVI independently predicted BCR following complete resection. Their integration into postoperative risk assessment may improve BCR prediction and guide individualized follow-up planning. Longer follow-up is required to draw definitive conclusions regarding their impact on mortality outcomes.
