BACKGROUND: Primary lymphoma of the gastrointestinal tract is an unusual disease for which the
optimal management strategy has not been clearly defined. The role of surgery in the management of
primary gastrointestinal lymphoma remains controversial.
METHODS
We retrospectively reviewed the management and the outcome of 55 patients a diagnosis of gastrointestinal lymphoma who were treated at Kyung-Hee University Medical Center during the period 1986-1997. Thirty-seven of them underwent a resection for cure, and 23 patients of them underwent chemotherapy. 18 patients underwent chemotherapy only. Radiation therapy was excluded due to the small number of patients. Surgery consisted of wide local resection of the primary tumor (curative for stages I and II, and palliative for stages III and IV), and regional lymph nodes, with re-establishment of bowel continuity. Chemotherapy involved 6-10 courses of CHOP-B (cyclophosphamide, adriamicin, vincristine, prednisone, and bleomycin). Survival curves were calculated by using the Kaplan and Meier method.
RESULTS
The mean age was 51 years (range: 3-82), the peak incidence of age was the fifth decades (34%), and the male-to-female ratio was 1.3:1. Common signs and symptoms at presentation were abdo minal pain (n=46), palpable mass (n=28), nausea/vomiting (n=26), and weight loss (n=18). The diagnostic sensitivities of ultrasound, contrast radiography, endoscopic biopsy, and computed tomography were 52%, 57%, 76%, and 78%, respectively. The primary tumor sites were the stomach (n=18), the terminal ileum & cecum (n=15), the small bowel (n=13), and the large bowel (n=9). The respective cumulative overall 5-year survival rates for stage I, II, III tumors were 89%, 74%, and 43% (p<0.05). The respective overall 5-year survival rate for resection only, resection with chemotherapy, and chemotherapy only were 100%, 78%, and 40% (p<0.05). By the Kaplan-Meier method, the prognostic factors of survival were stage and curative resection (p<0.05).
CONCLUSION
A curative resection in a stage I, II lymphoma confined to the gastrointestinal tract and to regional involvement may improve patient survival.
