Objectives: Gastric cancer is currently the fifth cancer in prevalence and the third cause of cancer mortality globally. Gastric cancer staging has become the axis of decision-making for the proper management of this type of cancer. This research seeks to evaluate the quality of contrast computed tomography (CT) of the abdomen for gastric cancer staging, whether early or advanced, in a high-complexity hospital in Medellín, Colombia.
Methods: A total of 160 patients diagnosed with gastric cancer confirmed by histology were retrospectively evaluated in a tertiary institution in the city of Medellín, Colombia, between January 2015 and September 2022. In 50 patients who met the inclusion and exclusion criteria, the results of the preoperative abdominal contrast CT and the findings of pathological anatomy in the surgical gastrectomy specimen were evaluated and correlated.
Results: Accuracy for tumor stage (T) was 30% (15/50), and accuracy for nodal stage (N) was 32% (16/50). The diagnostic accuracy of abdominal contrast CT for early gastric carcinoma was 75%, with high specificity (91%) but moderate sensitivity (83%).
Conclusion: Abdominal contrast CT in our population had a limited role in gastric cancer staging, both for tumor stage (T) and lymph node stage (N).
