Fibulin1 and mesothelin expressions in pancreas ductal adenocarcinoma.

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
objectiveThe balance between malignant tumor cells and the connective tissue surrounding them determines the aggressiveness of the tumor. We aimed to understand the effects of mesothelin (MSLN) and fibulin1 (FBLN1) expressions on survival in pancreas ductal adenocarcinoma (PDCA), and also whether these proteins have prognostic value for PDCA.
methodsOf 80 patients in total, 40 who underwent the Whipple procedure for diagnosed PDCA between 2009 and 2016, and 40 patients with diagnosed pancreatitis as the control group, were included in the present study. Immunohistochemically, MSLN, and FBLN1 expressions were evaluated retrospectively. We assessed the relationship between the degree of MSLN, FBLN1 expression, clinical-pathological features, and survival rates in PDCA cases.
resultsThe median follow-up duration was 11.4 (3-41) months. All of the patients for MSLN and FBLN1 were immune reactive. We detected a significant difference in MSLN expression between patients with PDCA and control groups, but not in FBLN1 expression. MSLN, FBLN1 expressions were categorized as lower-higher (L/H) groupings. There was no difference in the median overall survival (OS) of patients in the MSLN groups. The L-FBLN1 group had a median OS of 18 months (95% CI: 9.51-26.48) versus 14 months (95% CI: 13.021-14.97) in the H-FBLN1 group (interconnective tissue) (p=0.035). According to Kaplan-Meier analysis, L-FBLN1 expression in the tumor microenvironment was associated with longer survival in PDCA. The FBLN1 expression in the tumor microenvironment was shown to be significantly inversely related to OS (p=0.05).
conclusionThe FBLN1 expression, which is in the tumor microenvironment of PDCA, may serve as a prognostic biomarker.
