Abstract

PURPOSE
In spite of many published reports about the primary gastrointcstinal lymphoma in Korea, the majority of them unfortunately involved a small number of patients with diverse results conceming treatment, patient survival, and prognostic factors. There also were few reports mainly focusing on primary intestinal lymphoma alone. Therefore we studied the patient-survival and prognostic factors in 52 cases of intestinal lymphomas.
MATERIALS AND METHODS
We reviewed fifty two patients who received treatment due to primary intestinal lymphoma at Severance hospital, from January 1980 to June 1995.
RESULTS
The intestinal lymphomas were located in descending order of frequency at the terminal ileum, i1eocecal region, right colon, and the jejunum. The most common histologic type was diffuse large cell type and the majority showed an intermediate grade of differentiation. The average survival time was 40.7 months with a 5 year survival rate of 41.4%. The overall and complete remission rate of the intestinal lymphoma were 76.2%, 64.3%, respectively. Additional chemotherapy or radiotherapy to surgery improved remission rate. The overall 5 year survival rates were 50.4%, 47.3%, 33.3%, and 25.0% in stage I, II1, II2 and III~IV, respectively. The 5 year survival rate after curative resection was 57.0% and 16.6% after incomplete resection. The significant prognostic factors were residual tumor, site of the lesion, multiplicity, and adjacent organ invasion. However, the site of the lesion alone (worst in the jejunum) was the sole independent variable on multivariate analysis.
CONCLUSION
We concluded that early diagnosis and curative resection were important to improve survival rates in the primary intestinal lymphoma. More number of such cases are needed for further comparison of various treatment methods and results.
