ABSTRACT
Objective To analyze the prognostic factors associated with three-year survival outcome in patients with serous ovarian adenocarcinoma by classification tree.Methods Retrospectively we analyzed 81 cases with serous ovarian adenocarcinoma who had 3-year clinical outcomes and were hospitalized in People's Hospital from Jan 1991 to Dec 2003 by classification and regression trees(CART)software.Establish the classification tree.Results Among the factors that were associated with the 3-year survival rate,age was the most important factor,other factors in turn were International Federation of Gynecology and Obstetrics(FIGO)stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade.By substitution variable analysis,it was demonstrated that there was cross interaction between age and residual size as well as age and chemotherapy.Conclusion Age,FIGO stage,lymphoid metastasis,residual size after operation,chemotherapy and pathologic grade are important prognostic factors related with three-year survival probability of serous ovarian adenocarcinoma patients.
