PROBLEM TO BE SOLVED: To provide a method and a reagent for detecting a gastric cancer, colorectal cancer, pancreatic cancer or biliary tract cancer patient by analyzing genes with expression levels in peripheral blood that vary in association with gastric cancer, colorectal cancer, pancreatic cancer or biliary tract cancer cases, compared with normal healthy subjects.SOLUTION: A method for detecting a gastric cancer, colorectal cancer, pancreatic cancer or biliary tract cancer patient based on expression profiles includes: obtaining the expression profile of at least one gene selected from the group consisting of probes corresponding to genes with expression levels in peripheral blood that vary in gastric cancer, colorectal cancer, pancreatic cancer or biliary tract cancer cases, compared with normal healthy subjects. A reagent for detecting gastric cancer, colorectal cancer, pancreatic cancer or biliary tract cancer contains nucleotides or partial sequences thereof consisting of the nucleotide sequence of at least one gene selected from the group consisting of probes with expression levels that vary in gastric cancer, colorectal cancer, pancreatic cancer or biliary tract cancer, or nucleotides containing sequences complementary thereto. |
