Impact of microvasculature invasion subtype (MVI vs. LVI) and associated risk factors on survival outcomes in pancreatic cancer after curative surgery.

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
objectiveThis study aims to investigate the risk factors associated with microvasculature invasion (MI) in patients with pancreatic cancer and evaluate its prognostic significance.
methodsA retrospective analysis was conducted on the clinical data of 288 pancreatic cancer patients who underwent radical pancreatectomy between June 2012 and June 2024. The collected data included demographic characteristics, pathological findings, and laboratory results. Logistic regression analysis was performed to identify potential factors associated with the occurrence of MI. The Kaplan-Meier method was employed to estimate disease-free survival (DFS) and overall survival (OS). Univariate and multivariate Cox proportional hazards regression models were applied to assess the impact of various factors on patient prognosis.
resultsAmong 288 patients, MI was detected in 93 patients (32.3%). Positive microvasculature biomarkers, positive regional lymph nodes (RNP), poor differentiation grade, and reduced MCV might be independent risk factors for MI. Multivariate Cox regression analysis showed that MI, tumor site, RNP, grade, chemotherapy, chloride (Cl) and thrombin time were independent risk factors for DFS and OS. Among 93 patients with MI, no statistically significant difference in prognosis was observed between the MVI and LVI subtypes.
conclusionPositive microvasculature biomarkers, positive RNP, poor histological grade, and reduced MCV levels might serve as independent risk factors for the development of MI. The presence of MI was independent risk factors for DFS and OS. However, no significant prognostic association was observed between the specific origin of invasion (whether MVI or LVI).
