ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical features and prognostic factors of primary gastric diffuse large B-cell lymphoma (PG-DLBCL) and to evaluate the staging system and treatment modality of PG-DLBCL.</p><p><b>METHODS</b>The clinicopathological data of 69 patients with PG-DLBCL were retrospectively analyzed. Event-free survival (EFS) and overall survival (OS) were the primary endpoints.</p><p><b>RESULTS</b>The EFS rates at 1, 3, and 5 years were 83.8%, 71.1%, and 69.0%, respectively, with a mean EFS of 91.3 months. The 1-, 3-, and 5-year OS rates were 91.3%, 80.3%, and 72.4%, respectively, with a mean OS of 98.8 months. Univariate analysis revealed that either EFS or OS was significantly prolonged by the following factors (P < 0.05) modified Ann Arbor stage I(E) or II(E1) disease; normal lactate dehydrogenase (LDH) level; normal hemoglobin level; normal albumin level; International Prognostic Index (IPI) of 0 or 1; tumor size < 5 cm; and less depth of invasion. While gender, age, B symptoms at presentation, performance status and treatment modality were not significantly associated with the prognosis (P > 0.05). Cox regression model revealed that only modified Ann Arbor stage and albumin level were independent prognostic factors for EFS and OS.</p><p><b>CONCLUSION</b>The most accurate staging system and the exact role of different therapeutic options for PG-DLBCL are still debated. Further randomized prospective studies with a large number of patients are still needed to establish an optimal management for this disease.</p>
