The present invention relates to a method for diagnosing and screening cancer through measuring the concentration of des-R prothrombin activation peptide fragment F2 (des-R F2) in a serum. More specifically, des-R-prothrombin activation peptide fragment F2 which is the protein marker down-regulated specifically in liver cancer, breast cancer, and stomach cancer, and a method for diagnosis and screening of liver cancer, breast cancer, and stomach cancer by quantifying the protein marker. The protein marker of the present invention can be effectively used for diagnosis and screening of liver cancer, breast cancer and stomach cancer by comparing the expression of the said protein marker in a normal subject with that of a liver cancer, breast cancer, or stomach cancer patients. |
