Impact of surgical margins on recurrence and survival rate in patients with oral squamous cell carcinoma: A systematic review and meta-analysis.

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
backgroundOral squamous cell carcinoma (OSCC) accounts for approximately 90% of malignant neoplasms of the oral cavity. At early stages, the treatment of choice is surgical resection with clear margins, commonly defined as ≥5mm of tumor-free tissue. However, the optimal surgical margin in relation to recurrence and survival remains controversial. The objective of this study was to evaluate the impact of surgical margin status on local recurrence and overall survival in patients with OSCC through a meta-analysis. MATERIAL AND
methodsAn electronic search was conducted in Medline-PubMed, Web of Science, and Scopus up to January 2025. Two investigators independently selected the studies according to the inclusion criteria. The study included prospective and retrospective studies assessing patients with oral squamous cell carcinoma who underwent surgical treatment and reported data regarding surgical margin status, recurrence rates, and survival outcomes. The Newcastle-Ottawa Scale was used for non-randomized observational studies. Odds ratios were estimated with 95% confidence intervals, and forest plots were generated using random-effects or fixed-effects meta-analyses depending on heterogeneity. Sensitivity analyses and publication bias analyses were performed using funnel plots and Egger's test. All statistical analyses were conducted using Comprehensive Meta-Analysis software, version 3.0.
resultsPositive margins (<5mm) were significantly associated with a higher rate of local recurrence (OR=2.72; 95% CI: 2.04-3.62; p<0.001), while negative margins (≥5mm) were linked to a 1.58 -fold increase in the probability of 5-year survival (RR=0.63; 95% CI: 0.55-0.74; p<0.001).
conclusionsSurgical margin status is a prognostic factor for locoregional control and overall survival in OSCC. A cutoff value of ≥5mm is proposed as the optimal surgical margin.
