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
