Giant gastric ulcers: Malignancy yield and predictors from a 10-year retrospective single centre cohort:

2018 
Background and study aimsGastric cancer is known to reside in some gastric ulcers but what predicts this association is still unclear. Historically it has been thought that the increasing size of gastric ulcers may be a predictor for harbouring malignancy. Giant gastric ulcers are arbitrarily defined as ≥3 cm. The aim of this retrospective study was to examine patients with giant gastric ulcers within a single tertiary centre over a 10-year period. Our primary outcomes included the malignancy yield in giant gastric ulcers and to determine if any demographic, clinical or endoscopic predictors for malignancy exist. Secondary outcomes included the 30-day and 12-month mortality.MethodPatients with giant gastric ulcers ≥3 cm presenting from September 2005 to December 2015 were included in the study. Malignancy yield was obtained by looking at histology reports. Predictors for malignancy were tested using binary logistic regression, after demographic, clinical and endoscopic variables were tested using univaria...
