Relative impact of lymph-node metastasis and seminal vesical invasion on oncologic outcomes following radical prostatectomy.

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
backgroundWhile both seminal vesicle (SVI) and lymph-node invasion (LNI) have been identified as adverse prognostic variables among men undergoing radical prostatectomy (RP), the relative impact of each of these features on subsequent oncologic outcomes has not been well defined. We assessed the impact of LNI on long-term oncologic outcomes among patients with SVI at RP.
methodsWe reviewed 19,519 patients who underwent RP and identified 2043 with SVI. Metastasis-free (MFS), cancer-specific (CSS), and overall survival (OS) were estimated for patients with SVI, stratified by the presence and number of pelvic lymph node metastases. Cox proportional hazards models were used to evaluate the independent association of the number of metastatic nodes and lymph node density with oncologic outcomes among patients with SVI, controlling for age, year of surgery, margin status, preoperative PSA, pathologic Gleason score, extraprostatic extension, and use of adjuvant therapies.
resultsAt a median follow up of 12.1 years (IQR 7.0,18.6), 548 patients developed metastatic disease and 1331 died, including 406 who died from prostate cancer (PCa). We found that, among patients with SVI, the presence of a single positive lymph node was not associated with incrementally adverse oncologic outcomes compared to no nodal metastasis at RP, with 10-year MFS, CSS, and OS rates of 81.3% versus 78.3%(p = 0.18), 86.5% versus 89.8%(p = 0.32), and 72.8% versus 76.7%(p = 0.53), respectively. In contrast, on multivariable analyses, the presence of ≥2 metastatic nodes and a 20% lymph-node density cut off remained independently associated with worse survival.
conclusionsSVI represents an adverse pathologic feature such that the presence of a single positive pelvic lymph node did not further adversely impact prognosis. Meanwhile, a significant number of involved nodes was associated with decreased survival. These findings may aid in risk-stratification as well as clinical trial design for such high-risk patients following surgery.
