LYMPHOSARCOMA originating in the stomach presents the surgeon with an unusual and challenging problem. Although in the past it has accounted for only a small number of gastric neoplasms, it is currently being seen with increasing frequency. The prognosis for patients with these lesions appears to be much more favorable than for gastric adenocarcinoma (10.5%-66% five-year survival rate,1-5 as compared to 7%-27%6). However, the diagnosis is seldom made preoperatively and, in our experience, rarely correctly identified at surgery. Therefore, if our results with these lesions are to improve, it is imperative that the surgeon suspect the lesion, and effect proper treatment based on knowledge of its histopathology. We have reviewed the histories of patients with gastric lymphosarcoma seen at the Henry Ford Hospital with the purpose of improving our ability to make the correct diagnosis preoperatively, and to evaluate the treatment employed on the basis of a
