For example, a patient was randomly selected from the training group: a 50‐year‐old man (0 points); primary cancer located in the colon (11.25 points); TNM stage III (0 points); chemotherapy (0 points), cancer metastasising to the liver and lung (18.25 and 8.87 points); MSH6 test positive (0 points) and tumour marker CEA, CA199, CA125 and CA724 levels (35.00, 23.75, 54.00 and 17.00 points respectively) that exceeded the normal reference range. This evidence concerns the gene MSH6 and neoplasm.
