Design outcomes

Primary

MeasureTime frame
The primary objective of this study is to describe the real-world MSI/MMR testing pattern in 2L/2L+ treatment of patients with advanced multiple tumors in China.;The rate of MSI/MMR testing (%): calculate and rank the MSI/MMR testing rate by tumor type;Timing of the testing in the course of diseases;Sample sources (count with percentage);Methods and platform of testing (count with percentage for IHC/PCR);The number and sequence of biomarkers co-tested;Information of any other biomarker testing status (count);

Secondary

MeasureTime frame
the present study refer to the detailed treatment pattern of patients with MSI-H/dMMR for the 2L/2L+ treatment setting in the three tumor types in China;Treatment options of 2L/2L+ in patients based on MSI-H/dMMR;The treatment setting in previous line;
