ABSTRACT
The stomach is the most frequent site of extranodal lymphoma and primary gastric lymphoma might be distinguished from the nodal lymphoma by its different pathogenesis and prognosis. Based on the Isaacson's classification, clinico-pathologic reviews of 38 resected primary gastric lymphomas were done. Immunohistochemical stainings for PCNA, B and T cell markers, bcl-2 and p53 were performed. Eighteen were of low grade and 20 were of high grade. There were significant differences between low and high graders in the aspect of the size, depth of lesion, gross type, immunophenotype, staining intensity for PCNA, expressions of bcl-2 and p53. The overall 2-year survival rate was 85.3%. Factors with prognostic significance on survival by univariate analyses included immunophenotype, histologic grading and PCNA staining pattern. After multivariate analyses, immunophenotype proved to be a significant factor. We think that the histologic grading by Isaacson's classification and the immunohistochemical stainings performed were useful in pathologic and/or clinical aspects. The excellent survival rate in this study was partly due to the selection of resectable cases. However, earlier diagnosis and appropriate treatment might have contributed to the improved prognosis of gastric lymphoma in recent years.
