  • Patent number: 11193172
    Abstract: Novel means that enables prediction of prognosis of a patient with cancer or inflammatory disease is disclosed. In the method for prediction of prognosis of a patient with cancer or inflammatory disease according to the present invention, the expression level of the FROUNT gene in a sample collected from the patient is measured. Since FROUNT is a poor prognostic factor, the lower the expression level of the FROUNT gene is, the better the prognosis in the patient is predicted to be. Or, the expression level of the CC chemokine receptor/ligand gene in a sample collected from the patient is measured. Since the CC chemokine receptor/ligand gene such as CCR2 or CCR5 is a good prognostic factor, the higher the expression level of the CC chemokine receptor/ligand gene is, the better the prognosis in the patient is predicted to be.
