The gastrointestinal tract is the most common extranodal invasion site of non-Hodgkin lymphoma (NHL). Primary gastrointestinal NHL is often discussed together in most survival analyses. Primary intestinal NHL is significantly different from primary gastric NHL with regard to clinical features, pathological subtype, treatment, and prognosis. In this article, we analyzed clinical and pathological characteristics of primary intestinal NHL, and we also explored prognostic factors for primary intestinal NHL. A retrospective analysis was carried out on clinical data from 116 cases of confirmed primary intestinal NHL. The Kaplan-Meier method was used for the survival analysis. A Cox model was used for a multivariate analysis. In 116 patients with primary intestinal NHL, 79 patients were men (68.1%) and 37 patients were women (31.9%). In the cases used in this study, 68 were B-cell NHL and 48 were T-cell NHL. The age, incidence of intestinal obstruction, B symptom and performance status (PS) were closely related with pathological subtype. One-year and two-year survival rates were 76.7 and 58.3%, respectively. The log-rank univariate analysis showed male patients, PS score greater than or equal to two, hypoproteinemia, intestinal perforation, T-cell type, late stage (III/IV), no radical surgery, and no chemotherapy had relatively poor prognoses. Cox multivariate analysis shown that gender (95.0% CI 0.218-0.721), pathological subtype (95.0% CI 1.484-4.179), and radical surgery (95.0% CI 0.110-0.394) were independent prognostic risk factor for primary intestinal NHL. Male patients, T-cell intestinal lymphoma, and no radical surgery had rapid clinical processes and poor prognoses.
