An elevated concentration of M2-PK in the stool should always be clarified by undergoing colonoscopy. The gold standard of early detection of colon polyp/cancer is the invasive colonoscopy, but with high expense about $557, while tumor marker M2-PK Test expense only about $15-$25. The invasive colonoscopy makes acceptance of it low among ...
M2-PK, as measured in feces, is a potential tumor marker for colorectal cancer. When measured in feces with a cutoff value of 4 U/ml, its sensitivity has been estimated to be 85% (with a 95% confidence interval of 65 to 96%) for colon cancer and 56% (confidence interval 41–74%) for rectal cancer. [1] Its specificity is 95%. [2]
Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [2] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging. [2]
Lymphocyte antigen 6E is a protein that in humans is encoded by the LY6E gene. [5] [6] [7] Increased expression of Ly6E is associated with poor survival outcome in multiple malignancies as determined by a survey of more than 130 published clinical studies of gene expression studies on cancer tissue samples and adjacent normal tissues.

Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
Cancers and precancerous lesions that are ulcerated or rubbed by passing stool also may shed blood into the stool, which can be identified by a hemoglobin assay. [ 4 ] The American Cancer Society and the U.S. Preventive Services Task Force recommended colorectal cancer screening with a fecal immunochemical test every year, or a multi-target ...
The average "normal" blood pressure is 120/80, according to the American Heart Association. Almost half of all U.S. adults have elevated blood pressure (systolic pressure between 120 and 19 and ...
Three of these microRNAs (miR-16, miR-196a and Let-7a) [46] [57] have methylated promoters and therefore low expression in colon cancer. For two of these, miR-15 and miR-16, the coding regions are epigenetically silenced in cancer due to histone deacetylase activity. [ 58 ]
