ABSTRACT
BACKGROUND/AIM: Between 1976 and 1991, 25 patients underwent surgical therapy for primary gastric lymphoma. Clinical records were reviewed retrospectively to evaluate prognostic factors and impact of treatment on survival. RESULTS: Diagnostic sensitivity of endoscopic biopsy was 68%, positively of barium contrast studies for tumor was 33%. The overall 5-year survival rate was 67.3% (51.7% "free disease"): it was for stage I E 88.9%, for stages II 1E and II 2E respectively 68.6% and 44.4% and for stage IV 33.4%. Patients with tumors smaller than 5 cm had a 5-year survival rate of 80.8% whereas for patients with larger lesions survival rate was 44% (p < 0.05). Patients with low grade malignancy tumors had a 5-year survival rate of 81.9% versus 37.5% for high grade malignancy tumors (p < 0.03). Chemotherapy as adjuvant therapy was used in 17 cases (68%). 53% of them are "free disease" at minimum 4 years from the operation. CONCLUSIONS: We conclude that, surgical management of primary gastric lymphoma is mandatory but a planned multimodality therapy may produce complete remission and long-term "free disease" survival rate even in patients with relapse.
