[Radiological findings in malignant lymphoma of the stomach]

A retrospective review is presented of the clinical and roentgenographic findings of 40 patients with malignant lymphomas of the stomach treated at the Medical University Hannover during the period from 1971-1983. All cases of Non-Hodgkin-Lymphoma (35 primary and 5 secondary) were classified by modified Kiel classification. All patients were staged retrospectively, using modified Ann Arbor staging. In 33 patients the primary choice of treatment were operation, in 4 chemotherapy, and in three patients primary radiation therapy. The male-female ratio was 1:1, the average age at the moment of diagnosis was 58 years. The majority of the tumors were located in the corpus and the antrum with an average diameter of 8 cm. The evaluation of the roentgenographic presentation of gastric lymphoma showed in 75% a combination of different radiologic patterns. According to the main radiologic feature the ulcerating form was found in 11, the polypoid type in 10, the disruption of the mucosal picture (area, folds) in 12, and the gastric wall infiltration was found in 7 of all patients. The 5-year survival rate of all cases with primary lymphoma of the stomach was 55%.
