[Prognostic factor analysis of 116 cases of primary gastrointestinal non-Hodgkin's lymphoma].

ABSTRACT

OBJECTIVE: To investigate the factors that affect the prognosis of primary gastrointestinal non-Hodgkin's lymphoma (PGI-NHL). METHODS: The clinical data of 116 patients with pathologically confirmed PGI-NHL we treated from January 1993 to December 2003 were analyzed retrospectively. Kaplan-Meier survival analysis was used for analyzing the survival of the patients, and Log-rank test was performed to compare the survival rates in relation to different prognostic factors. RESULTS: The 3-year and 5-year survival rates of the patients were 63.8% (74/116) and 48.2% (40/83), respectively. Univariate analysis revealed that the factors affecting the prognosis of the patients included the presence of B symptom, tumor size, clinical stage, pathological type, depth of invasion, and treatment methods. The patients with B symptom, tumor size no less than 10 cm, advanced clinical stage (stages III(E) and IV(E)), T-cell type, and invasion beyond the serosa who received only surgical management had poorer prognosis than those free of B symptom with tumor size <10 cm, early clinical stage (stages I(E) and II(E)), B-cell type, and submucosal or serosal invasion managed with chemotherapy alone or in combination with surgery. Multivariate analysis showed that B symptom, tumor size no less than 10 cm, advanced clinical stage (stages III(E) and IV(E)), T-cell type, invasion beyond the serosa, and surgery alone were independently associated with poor prognosis. CONCLUSION: The tumor size, clinical stage, pathological type, treatment methods are the independent factors affecting the prognosis of patients with PGI-NHL.
