Additionally, serum levels of stathmin were measured in other patients include head and neck cancer, colorectal cancer, gastric cancer and hepatocellular carcinoma, the results showed that the stathmin concentration was higest in head and neck cancer (8.88±4.34 ng/ml) and lowest in colorectal cancers (5.24±2.34 ng/ml) (Figure 1E). This evidence concerns the gene STMN1 and colorectal cancer.
