    Abstract:
    BACKGROUND: To analyze the main clinical and biological data and the response to therapy in 15 patients with primary gastrointestinal lymphoma (PGIL) from a series of 76 patients with HIV related non-Hodgkin's lymphoma (NHL) diagnosed in a single institution in a 13 years period. PATIENTS AND METHODS: The main clinical, biological and evolutive data were recorded. Pathologic diagnosis of PGIL was made according to the REAL classification. Clinical stage was determined by the Ann Arbor system modified by Rohatiner et al. Response to therapy as well as overall survival (OS) were studied. Results were compared with non-PGIL HIV-related NHL patients. RESULTS: Mean age of the series was 38 years. Thirteen patients were male, and 8 intravenous drug abusers. Then had bad performance status (ECOG 2-4) and 11 B symptoms. All patients had a high grade malignant PGIL and the localization was gastric in 10 cases. The most frequent symptoms were abdominal pain (11 cases), gastrointestinal bleeding (4) and dysphagia (3). Ten patients had advanced stages (IIE2-IV). The median CD4 cell count was lower in PGIL patients (92 x 10(6)/l vs 148 x 10(6)/l; p < 0.05). Thirteen patients received intensive chemotherapy with CHOP regimen (in 5 surgical procedures were previously made). Complete response (CR) was obtained in 4 patients (31%) and 1 of them relapsed. Median OS was 10 months vs 16 months non-PGIL HIV-related lymphoma patients (p < 0.05). CONCLUSIONS: PGIL in HIV patients often presented advanced stages and high grade of malignancy. The most common localization is the stomach, and these patients usually have bad performance status and a low CD4 lymphocyte count. Response to therapy is poor. In our series OS was worse in PGIL patients than in the rest of HIV-related NHL, possibly due to the high degree of immunosuppression in the formers.
