Histopathological features of gastrointestinal and pancreatic neuroendocrine neoplasms: An 11-year retrospective study from a tertiary center in Saudi Arabia.

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
objectivesTo evaluate the clinicopathological features of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) over 11 years at a single tertiary institution in Saudi Arabia.
methodsIn a retrospective review, data from 71 patients diagnosed with GEP-NEN, at a tertiary academic center in Jeddah, Saudi Arabia, between January 2014 to December 2024, were analyzed for demographics, clinical presentation, tumor location, size, pathology, grade, and immunohistochemistry. The statistical analyses included Chi-square, Mann-Whitney-U, and Spearman's correlation tests.
resultsThe cohort had a mean age of 54.9±15.1 years and comprised 62% males. Most tumors originated in the foregut (62.0%) and were unifocal (83.1%). Abdominal pain (29.6%) and weight loss (9.9%) were the most common symptoms, and 18.2% of cases were incidentally detected. Well-differentiated neuroendocrine tumors represented 77.5% of the cases, with grade 1 being the most prevalent (60.0%). Synaptophysin was detected in 100% of patients and chromogranin A was detected in 90.1% of patients. The tumor size was significantly positively correlated with the tumor grade (r=0.57,
conclusionWell-differentiated neuroendocrine tumors originating in the foregut were predominant in this cohort. These findings provide important regional insights into GEP-NENs and support the need for further research to enhance the diagnostic and treatment strategies.
