Radiologic Evaluation Of Early Gastric Cancer

Gastric cancer, if detected in the early stage, has a considerably better diagnosis than advanced carcinoma. Early gastric cancer is characterized by limitation of the malign cells to the mucosa and submucosa. It does not infiltrate the deep layers of the stomach. Lymph node involvement and distant metastasis are rare. Collaboration of gastroenterologists, radiologists, pathologists and surgeons is fundamental for the detection of the cancer in the early phase and for the achievement of a complete cure by surgical operation or endoscopic mucosal resection.
In the countries where the prevalance of gastric cancer is high, the radiologic investigation as well as gastroscopy is very important in the survey and early diagnosis. In this article, imaging modalities and radiologic findings in the diagnosis of early gastric cancer will be emphasized. The double contrast upper gastrointestinal examination is widely recognized as the best radiologic technique in the diagnosis of early gastric cancer. The macroscopic classification of the early gastric cancer defined according to the endoscopic observations can be adapted to the radiologic data. The radiographic findings include mucosal granularity and nodularity, filling defect due to elevated lesions that protrude into the lumen, plaque-like elevations, shallow areas of ulceration with spiculated margins, blunted, nodular, or fused folds converging to the edge of the ulcer, or some combination of these findings. In addition to the double contrast examination, the diagnostic role of the computed tomography, virtual gastroscopy, endoscopic ultrasonography, transabdominal ultrasonography, magnetic resonance imaging, and positron emission tomography will also be mentioned throughout the text.Keywords: Stomach; neoplasm; radiologyTurkiye Klinikleri J Surg Med Sci 2007, 3(44):38-48
