Mutation analysis of the 41 ESCCs and 11 ESCC cell lines. In the 20 responders and 21 non-responders, mutations of 55 cancer-related, 46 repair-related, and 18 SWI/SNF-related genes were analyzed. There was no difference in the incidence of mutations between the two groups. When a sample had two or more mutations in one gene, the box is colored in black. When a sample had one mutation in one gene, the box is colored in gray.
