Abstract

in English, Chinese

OBJECTIVE:

To investigate the clinicopathological features of primary gastrointestinal non-Hodgkin's lymphomas (PGI-NHL) and their prognostic values.

METHODS:

The clinical and pathological data of 216 patients diagnosed as PGI-NHL from Zhejiang Cancer Hospital were analyzed retrospectively. χ² test, log-liner model analysis, COX proportional hazard regression analysis and Life-table survival analysis were used to analyze the survival status of the patients by SAS 8.2 software, and Log-rank test was performed to couple the overall survival rates with different prognostic factors.

RESULTS:

Totally, the age of onset was 8 to 89 years with the median age of 56.5 years. Male versus female was 1.27∶1(121∶95). The most frequently involved location was stomach (147 cases, 68.1%), followed by ileocecus (25 cases, 11.6%), large intestine (20 cases, 9.3%), small intestine (17 cases, 7.9%) and multiple GI involvement (5 cases, 2.3%). 182 cases were classified as B cell lymphomas, 22 cases as T cell lymphomas, and 12 cases not classified exactly due to insufficient data. The 3-year and 5-year survival rates of the patients were 69.4% and 53.3%, respectively. Univariate analysis revealed that age>60 years, ECOG≥2, high LDH level, stage Ⅲ-Ⅳ, IPI≥2, T cell type and intestinal involvement were predictors for poor prognosis. IPI≥2, T cell type and intestinal involvement were independent adverse predictors for prognosis by multiple COX proportional hazard regression analysis. Among different treatment groups, cases received chemotherapy combined with local radiotherapy gained the best survival status.

CONCLUSION:

B-cell lymphoma was the main pathological type in PGI-NHL; IPI≥2, T-cell type and intestinal involvement are independent adverse predictors for prognosis; chemotherapy combined with local radiotherapy might be the choice of approach for advanced stage and aggressive PGI-HNL.
