Objective: There is heterogeneity in non-Hodgkin's lymphoma. The purpose of this study is to investigate the prognostic factors of invasive non-Hodgkin's lymphoma.
Methods: From June 2002 to June 2006, 137 patients with invasive non-Hodgkin's lymphoma were treated by regular regimen consisting of radiotherapy and chemotherapy. The clinical data including prognostic factors was analyzed by SPSS 10.0.
Results: After treated with chemotherapy and radiotherapy, 35 (25.5%) patients achieved CR, 67 (48.9%) PR, 6 (4.3%) SD, 29 (21.2%) PD, ORR (objective response rate) of this series was 74.5%. The overall 4-year survival rate was 70.8%. The PFS (prognosis free survival) was 42.7%. Multivariate analysis using Cox model indicated that clinical stage III-IV, PS score > or = 2, more than 2 external nodal involvement were closely correlated with overall survival.
Conclusion: The overall survival of invasive non-Hodgkin's lymphoma treated with present combined therapy regimen has been improved greatly. However, further investigation is still needed for exploring more effective individualized treatment regimen.
