Abstract
Gastrointestinal (GI) malignancies are a major cause of morbidity and mortality worldwide, accounting for about 35% of cancer deaths. GI malignancies are diagnosed by clinical, laboratory, endoscopic, and imaging data. This chapter explores a variety of GI malignancies and highlights situations in which the combination of radiologic and molecular modalities helps highlight pathology. Esophageal malignancies are seen more commonly in men with a peak age in the sixth to eighth decades. Gastric malignancies represent the fifth most common malignancy, with highest incidence in east Asia. Small bowel malignancies are remarkably rare, accounting for less than 5% of GI malignancies. The incidence is rising, particularly for neuroendocrine tumors (NETs), which are now the most common small bowel malignancy, followed by adenocarcinomas, lymphomas, and gastrointestinal stromal tumors. Primary appendiceal neoplasms are uncommon GI tumors. The vast majority of appendiceal tumors consist of NETs and epithelial neoplasms, including mucinous and nonmucinous types.
