Abstract
-
PURPOSE: The purpose of this study was to evaluate the differences in survival rates between primary gastric
and intestinal gastrointestinal non-Hodgkin's lymphoma (NHL) and to investigate risk factors for survival.
MATERIALS AND METHODS
We reviewed survival rates and risk factors in 60 cases with stage I and II primary gastrointestinal lymphomas treated at Keimyung University Hospital between January 1972 and August 1999.
RESULTS
No differences in sex, age, histology, stage, or percentage of curative resection were observed between primary gastric and intestinal lymphoma. The overall 10-year survival rates of gastric and intestinal NHL were 68.1% and 39.6%, respectively (p<0.05). The overall 10-year survival rates in stage I gastric and intestinal NHL were 66.7% and 70.0%, respectively, while those in stageII were 65.1% and 23.7%, respectively (p<0.001). A multivariate analysis of risk factors for survival revealed that the site of origin (5.68, CI=1.8-17.5) and stage (4.22, CI= 1.19-14.85) were significantly correlated with prognosis (p<0.05). There was no significant difference in the expression of bcl-2 and p53 between gastric and intestinal NHL. Furthermore bcl-2 and p53 expressions were not correlated with the prognosis.
CONCLUSION
This study indicates that stage II primary intestinal lymphoma has lower survival rate than gastric lymphoma.
