Abstract
OBJECTIVE
To date, few attempts have been made at clinical features and prognostic factors of primary peritoneal carcinoma (PPC) because of low prevalence. The aim of this study is to evaluate the clinical characteristcs and determine the prognosis factors of PPC. METHODS: From March 1996 to March 2004, a total of 23 women newly diagnosed with PPC were recruited into the study. Overall survival and prognostic factors were evaluated using Kaplan-Meier method and Cox regression model. RESULTS: The mean age of patients was 58.7+/-7.6 years and the FIGO stage was advanced disease; stage IIIc (73%) and IV (27%). The mean survival time for patients enrolled was 26.0 months. By univariate analysis, tumor state (p=0.028), performance status (p=0.045), the presence of initial debulking operation (p=0.035), and normalization of CA125 at 3 months of treatment (p=0.003) were significantly correlated with survival. On multivariate analysis, only the normalization of CA125 at 3 months of treatment remained as the independent factor for survival (Odds ratio, 6.896; 95% Confidence interval, 1.504-31.623; p=0.013). CONCLUSION: The mean survival time for patients with PPC was 26.0 months, and the normalization of CA125 at 3 months of treatment was identified as the independent prognostic factor. From this study, we analysis the clinical characteristics of PPC and provide more precise understanding of this disease.
