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
