For 81 CRC and AA stool samples, methylated SEPT9 was detected in 66.7% of AA (8/12), 86.7% of stage I (13/15), 94.4% of stage II (17/18), 78.3% of stage III (18/23), 77.8% of stage IV (7/9), and 71.4% of unknown stage (5/7) samples (Table 2 and Figure 2A). This evidence concerns the gene SEPTIN9 and colorectal carcinoma.
