Therapeutic comparison of chemotherapy and surgery for early stage diffuse large B-cell gastric lymphoma.


ABSTRACT: PURPOSE:The use of surgery versus stomach-preserving treatment for primary gastric lymphoma has caused controversy among doctors. This retrospective, single center study aims to evaluate the efficacy and benefit of stomach-preserving treatment against surgery for early stage diffuse large B-cell lymphoma of stomach. MATERIALS AND METHODS:From August 1991 to January 2006, 43 cases of early-stage diffuse large B-cell gastric lymphoma were reviewed. RESULTS:Eleven cases were treated with chemotherapy or chemotherapy plus radiation (CT +/- RT), 17 were treated with surgery alone (OP), and 15 were treated with surgery plus adjuvant chemotherapy (OP + CT). The complete remission and response rates were 63.6% and 90.9% in those treated with CT +/- RT (7 complete responders, 3 partial responders, 1 non-responder), 100% and 100% in those treated with OP, and 100% and 100% in those treated with OP + CT, respectively. Five-year overall survival rates were 85.7%, 87.5%, and 100% in those treated by CT +/- RT, OP, and OP + CT, respectively (p=0.76). The five-year disease free survival rates were 100%, 87.5% and 100% in those treated by CT +/- RT, OP, and OP + CT, respectively (p=0.99). There was no significant difference in overall survival and disease free survival between modalities. Even though there are no definite differences in the number of complications between those treated by CT +/- RT or OP, these facts reflect little concern on complications after surgery. CONCLUSION:In preventing morbidity arising from early or late complications from surgery and promoting quality of life, chemotherapy should be a primary consideration for early stage diffuse large B-cell lymphoma of the stomach.
