[Primary malignant lymphoma of the stomach. Analysis of 38 cases].
A retrospective analysis is presented of 38 cases of malignant lymphomas of the stomach, 20 of the reticulum cell type, 6 lymphoblastic, 6 lymphocytic and 4 mixed forms. Two patients had a primary Hodgkin's malignant lymphogranuloma. A follow-up was obtained for 35 patients. There proved to be no significant difference between the symptomatology of carcinoma and lymphoma of the stomach. In patients with lymphomas only signs of stenosis were missing, although the majority of the tumors were located in the antrum. As a consequence of the extreme tendency of the lymphomas to exulcerate (89%), the mean duration of symptoms of 21/2 months (patient's delay) is shorter than that for carcinomas. Malignant lymphomas of the stomach are very difficult to identify as such by radiology and endoscopy, because of their uncharacteristic macroscopic appearance. The best diagnostic method has proved to be endoscopic wire-loop biopsy, which serves to obtain adequate material for histology. An unexpected finding was that at the time of operation half of the patients had clinical stage I E. This indicates that lymphomas remain limited to the stomach longer than carcinomas do. The prognosis depends on both histological type and clinical stage. It is somewhat better than that of nodal malignant lymphomas. The 5-year survival rate of all cases with malignant lymphoma of the stomach is 31%.
