Relation between location and histology type of gastric adenocarcinoma at IAHULA Merida Venezuela patients. Surgical implications

Abstract

Gastric cancer is a common cancer worldwide; his anatomic pattern did change with differences between populations. It is important to know the relation between localization and histology, because of different surgical exigencies. Objective: in order to determinate the behavior of gastric cancer in Merida, Venezuela. Methods: transversal and observational study, with IAHULA gastric adenocarcinoma patients between January 2016 to December 2020. Results: the anatomical localization distribution was: 47 antro pyloric, 33 at cardias and the other cases at the gastric body. Histological distribution: Diffuses or signet ring cells adenocarcinomas were most common in every gastric localization but similar numbers to the proximal location were placed, different results at antro/pyloric with 36 diffuses and 11 intestinal according the Laurent classification. The antro/pyloric cases had significant relation with resection of subtotal gastrectomy (p 0,000). There was not association between the gastric location and the Laurent classification (p 0,073). Conclusion: no matter the importance described to the initial anatomical location and the histology type talking about surgical implications, there was no relation between both factors, so there is a big heterogeneity in gastric adenocarcinoma in Merida, Venezuela.
