Introduction: Current Status and Future Advances in Cancer Biomarkers

Abstract

Cancer is a major health problem and a leading cause of morbidity and mortality worldwide. The cancer burden can be reduced significantly using reliable, robust, sensitive, accurate, validated and specific biomarkers for early diagnosis, better prognosis and prediction. Traditionally, a number of biomolecules exhibit the potential to be used as diagnostic, prognostic and predictive biomarkers roles, however, they failed to be used in point-of-care settings for routine analysis. Recent advancements in sequencing techniques and analytical methods facilitate the development of novel and effective cancer biomarkers (liquid biopsies) with the fidelity of clinical application. These biomarkers provide personalized “omics” based information on the pathological state, molecular nature and biological aggressiveness of individual patients. Nevertheless, standardized platforms and/or methods for these biomarkers are yet to be established. Thus, adopting a combination of classical and new cancer biomarkers would offer a better understanding of the disease, resulting in improved clinical outcomes for patients with cancer.<br>
