SURGICAL TREATMENT OF PRIMARY GASTRIC LYMPHOMA : A RETROSPECTIVE STUDY OF 13 CASES

Abstract

A retrospective study of 13 patients who were operated on primary gastric lymphoma was made to evaluate the influence of clinicopathologic features and method of treatment on survival. There was an association found between tumor size and depth of invasion, or lymph node involvement especially in the localized type. More specifically, when the tumor measured 10cm or more in diameter, the tumor stage advanced except for the infiltrative-flat type. The estimated 5-year survival rates were 75% for stage Ⅰ, 66.7% for stage Ⅱ and 50% for stage Ⅳ, respectively. We experienced a case of recurrence in the remnant stomach after resection for an early stage lymphoma of the infiltrative-flat type, and two cases of over 10-year survival after extended resection with adjuvant chemotherapy for advanced stage Ⅳ lymphoma. Therefore, we concluded that adequate resection should be performed even for early lymphoma, and also that adjuvant chemotherapy be given for advanced lymphoma.
