Abstract: Abstract Statistical methodologies for evaluation of surrogate endpointsSurrogate endpoint have been developed actively since 1989. A meta-analytic approach is frequently applied with data from several randomized controlled trials, and the surrogacySurrogacy measures are evaluated at the individual level and at the trial level. This approach needs individual patient dataIndividual patient data for each trial and requires collaborative work with several professionals. In this chapter, we introduce the Global Advanced/Adjuvant Stomach Tumor Research International Collaboration (GASTRIC) project, which is an academic, worldwide project that conducts individual patient data meta-analyses of randomized controlled trials of post-operative adjuvant chemotherapy for resectable gastric cancer or chemotherapy for advanced/recurrent gastric cancer. We describe our statistical method for the evaluation of surrogate endpoints. In particular, we focus on the practical aspects of group establishment, data collection, and data analysis. Finally, future perspectives for the evaluation of surrogate endpoints are discussed.
