ABSTRACT
Gastric neoplasms are an important contributor to cancer-related mortality. Of the various neoplasms that can affect the stomach, adenocarcinoma is the most common and accounts for up to 95% of all gastric neoplasms. Less common are gastric lymphomas, gastrointestinal stromal tumors, neuroendocrine tumors, and metastatic disease involving the stomach (Table 1). This chapter considers the epidemiology, pathogenesis, clinical presentation, diagnostic evaluation, treatment, and prognosis of these neoplastic diseases.
