REGRESSION
For this study, the sample size calculation cannot be determined. Based on our experienceDescriptive statistics will include mean (with standard deviation, SD±) and median (interquartile ranges, IQR) for continuous data and absolute and relative frequencies for categorical data. Continuous variables were compared using the standard t-test or Mann-Whitney test, and the chi-square test or Fisher's exact test will be used for categorical variables. Multivariate binary logistic regression, with the odds ratio and the respective 95% confidence intervals, will be used to identify possible factors related to peritoneal response and to identify risk factors related to treatment toxicity.Survival curves will be evaluated using the Kaplan-Meier method and compared using the log-rank test. The prognostic factors associated with survival will be estimated using the univariate and multivariate Cox proportional hazards model. All statistical tests will be two-sided, and p-values<0.05 are considered significant. Statistical analyses will be performed using the SPSS software, version 20 (SPSS, Chicago, IL).
