It is necessary to distinguish between disease-related and drug-related biomarkers.Disease-related biomarkers give an indication of the probable effect of treatment on patient (risk indicator or predictive biomarkers), if a disease already exists (diagnostic biomarker), or how such a disease may develop in an individual case regardless of the type of treatment (prognostic biomarker).
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. [2]
Those selected genes can be identified as diagnostic biomarkers for further validation. mRNA biomarker validation: The mRNA biomarkers are selected by bioinformatic methods. Thus, they need to be tested with real samples with reliable experiment on real identified samples with clear and accurate clinical diagnosis.
Prognostic markers are biomarkers used to measure the progress of a disease in the patient sample. [1] Prognostic markers are useful to stratify the patients into groups, guiding towards precise medicine discovery. The widely used prognostic markers in cancers include stage, size, grade, node and metastasis. In addition to these common markers ...
For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.
An imaging biomarker is a biologic feature, or biomarker detectable in an image. [1] In medicine, an imaging biomarker is a feature of an image relevant to a patient's diagnosis. For example, a number of biomarkers are frequently used to determine risk of lung cancer .
