<p><b>OBJECTIVE</b>To evaluate the clinical characteristics, results of treatment, and prognostic factors of patients diagnosed as having primary female genital system lymphoma (PFGSL).</p><p><b>METHODS</b>Twenty-eight cases of PFGSL were retrospectively surveyed and the clinical data of the patients were analyzed by statistic software package of SPSS10.0 for relation between clinical stage, grade, pathologic feature, treatment and prognosis.</p><p><b>RESULTS</b>The median age was 44 in the cohort. It mainly involved cervix uterus, ovary and vulva. The disease had a broad range of pathologic type and 20 patients were diagnosed as suffering from B-cell by immunophenotyping, 4 patients were diagnosed as T-cell and 4 patients lesions were indefinite. According to International Working Formulation (IWF), 66.7% belonged to the intermediate-grade. The Ann Arbor stage included Stage I(E)-12 pts (42.86%), Stage II(E)-3 pts (10.7%), Stage III(E)-1 pts (3.6%) and Stage IV-12 pts (42.86%). According to International Prognostic Index (IPI), 10 were low risk, 9 low-medium risk, 3 medium-high risk and 6 high risk, The median follow-up of the surviving patients was 2.0 years (range 3 months-17 years), The 5-year overall survival rate was 39.3%. Most patients were given comprehensive treatment without any mode showing significant advantage over the others in survival (P = 0.2554), The involved organs, Ann Arbor stage, IWF and also IPI were significant prognostic factors for survival,</p><p><b>CONCLUSION</b>The management of PFGSL should be based on comprehensive treatment including chemotherapy as the chief means. The significant prognostic factors of survival is Ann Arbor stage, IPI, IWF and the kind of involved organs.</p>
