ASSESSING COLORECTAL CANCER BY MEASURING HEMOGLOBIN AND M2-PK IN A STOOL SAMPLE
First Claim
1. A method for assessing in vitro the absence or presence of colorectal cancer in a patient, the method comprisingproviding a stool sample from the patient,measuring in the sample a concentration of hemoglobin and a concentration of pyruvate kinase isoform M2 (M2-PK), andcorrelating the concentrations measured to the concentrations of hemoglobin and M2-PK known to be associated with the absence or presence of colorectal cancer in a population.

Abstract
The present invention relates to a method aiding in the assessment of colorectal cancer. The method especially is used in assessing the absence or presence of colorectal cancer in vitro. The method is, for example, practiced by analyzing biochemical markers, comprising measuring in a stool sample the concentration of hemoglobin and M2-PK and correlating the concentrations determined to the absence or presence of colorectal cancer. To further improve the assessment of colorectal cancer in a method of this invention the level of one or more additional marker may be determined together with hemoglobin and M2-PK in a stool sample and be correlated to the absence or presence of colorectal cancer. The invention also relates to the use of a marker panel comprising hemoglobin and M2-PK in the early diagnosis of colorectal cancer, and it teaches a kit for performing the method of the invention.
