OBJECTIVE: To study the clinicopathological characteristics and prognostic factors in Chinese patients with primary intestinal non-Hodgkin's lymphomas (PINHL). METHODS: The clinical symptoms, pathological features, diagnostic and prognostic factors of 273 cases diagnosed with PINHL from our center were analyzed. RESULTS: Among 273 cases, 189 were male and 84 female, the male to female ratio was 2.3:1. The age of patients ranged from 2 to 85 years old with the median age of 46. The most frequent site of the lesions was ileocecus (n=83, 30.4%). The clinical symptoms of PINHL were unspecific with abdominal mass frequently seen in B-cell lymphoma, and perforation, hypogastric pain and "B" symptoms more common in T-cell lymphoma. Endoscopic biopsy diagnosis rate was 90.3%. Of 273 cases, B-cell lymphoma (n=232, 85.0%) dominated PINHL with the most common subtype of diffuse large B-cell lymphoma-not otherwise specified (DLBCL-NOS) (n=132, 48.4%), while the T-cell lymphoma (n=41, 15.0%) were much less seen with the most common subtype of enteropathy-associated T-cell lymphoma (EATL) (n=15, 36.6%). There were 245 cases were followed up, including 206 cases of B-cell lymphoma and 39 cases of T-cell lymphoma, it was found that the prognosis of B-cell lymphoma is much better than that of T-cell lymphoma (P<0.05). Operation had no significant effect for the overall survival rate. But for patients with aggressive lymphoma, operation can improve the survival rate. CONCLUSION: It indicates that PINHL often occurs as B cell type, DLBCL-NOS is the most common histological type. Ileocecus is the most common site involved and enteroscope biopsy is a good method of diagnosis. Compared with T-cell lymphoma, B-cell lymphoma has different clinical manifestations and a better prognosis. Patients with aggressive lymphoma can benefit from operation.
