Usefulness of chorionic gonadotropin in premalignantgastric lesions

Abstract

Introduction: knowledge of premalignant gastric lesions is crucial because only in this way can it be informed, educated, and a surveillance plan drawn up when they are diagnosed. Objective: to evaluate the diagnostic value of chorionic gonadotropin as a tumor marker in premalignant gastric lesions in patients treated in the Gastroenterology service of the “Dr. Agostinho Neto” General Teaching Hospital. Guantánamo. January 2021 – january 2023.Method: an analytical, longitudinal, prospective study was carried out in patients treated in the gastroenterology service. Results: the elevated lesion predominated in 55,5%, a greater number of patients with positive chorionic gonadotropin in 75,6%, with high sensitivity of 92,3% for dysplasia, specificity and positive predictive value of 100% and high negative predictive value between 78,4% and 90,5%. Conclusions: in the investigation, there was a predominance of the endoscopic finding of an elevated lesion, a greater number of patients with positive chorionic gonadotropin, and it turned out to be a marker with diagnostic value to be taken into account as a tool in premalignant gastric lesions.
