Purpose: Transcriptomic profiling was performed for microsatellite instability-high (MSI-H)/mismatch repair-deficient (dMMR) gastrointestinal (GI) tumors to determine the predictors of response to PD-1 blockade. Experimental design: Thirty-six patients with MSI-H/dMMR GI tumors, including gastric cancer, colorectal cancer (CRC), cholangiocarcinoma, small intestine cancer, …
The patients with high microsatellite instability (MSI-H)/mismatch repair deficient (dMMR) tumors recently have been reported that can benefit from immunotherapy, and MSI can be used as a genetic instability of a tumor detection index. However, many studies have shown that there are many heterogeneous phenomena in patients with MSI tumors in terms of …
