Abstract
Four cases of primary gastric malignant lymphoma followed years later by adenocarcinoma of the stomach are described. Review of the literature revealed eleven other cases of these two lesions occurring in the same patient. In our four cases gastric adenocarcinoma developed many years after successful treatment of primary gastric lymphoma by partial gastrectomy. In three patients gastrectomy had been followed by radiation treatment to the upper abdomen. The relationship between the two tumors is discussed, including the possible role of treatment of the lymphoma in the development later of gastric adenocarcinoma. It is important to consider the possibility of the later development of a second primary gastric cancer in a patient who develops gastric symptoms, after successful treatment for primary gastric neoplasm.
