Validez de la tomografía multicorte en la invasión local (t) del adenocarcinoma gástrico en pacientes atendidos en el Instituto del Cáncer SOLCA - Cuenca 2010 - 2017

Abstract

Objectives: to determine the validity of multislice tomography in the local invasion (T) of gastric adenocarcinoma in patients treated at the Institute of Cancer Society "SOLCA" center of Cuenca, in the period July 2010 - July 2017. Method and materials: a diagnostic test validation study was conducted with 129 patients, taking histopathology as a gold test. It were reviewed the clinical histories of each patient with a confirmed diagnosis of gastric adenocarcinoma. The variables studied were age, sex, histological type, tumor report, nodule, tomographic metastasis (TNM) given before surgery and / or sample taking for biopsy as well as the degree of invasion reported by histopathology by tumor, nodule, metastasis (pTNM). The data was entered into a database. Information was obtained on sensitivity, specificity, positive predictive value, negative predictive value, positive and negative likelihood indexes. Results: The distribution of gastric adenocarcinoma was similar in both men and women, presenting more frequently in older adults, the intestinal variant was more prevalent. The highest prevalence of T (Tumor) by tomography was in T3 and T4. The highest prevalence for pTNM (pathology) was for pT4. The highest sensitivity of multislice tomography was for T3 and the highest specificity corresponded to T1. The test proved invalid in sensitivity for T2. Conclusion: Multislice tomography is especially useful for diagnosis in stage T3, similar to that reported in published studies
