Abstract:Objective: Design tables of the required sample sizes for survival studies including 1,530 projects were made out based on the generalized asymptotic normal procedure for clinical applications. Methods: The procedure was programmed in the C language and the output was printed in the destgn tables with usual form. Results: Common projects can be found in the tables. They are matched with the test on two survival rates, reducible when there is no censoring, free from the assumption of proportional hazards, The observed power coinccides with the prescribed power in usual clinical situations. Conclusion: The tables are appropriate with planning clinical cancer studies, especially useful for clinicians or the relevant investigators.
Keywords:asymptotic normal procedure  censorship  experimental design  sample size  survival rate
