Liquid Biopsy Market Analyse in New Research Report
Cancer diagnostics based on measuring biomarkers in tissue samples has already in the past decade provided revolutionary advances in diagnosis, prognosis, and therapy selection. A major drawback of the tissue-based approach centers on the need for invasive surgical procedures in sample collection, which in a great many instances preclude following the progression or regression of disease during therapy.
In recent years, an impressive number of cancer biomarker researchers have turned their attention to the analysis of markers present in biological fluids, which can be collected with minimal invasiveness and permit following the disease over time. This highly dynamic field has come to be called liquid biopsy. In the past few years a significant and growing number of startups and several major companies have taken up the challenge of commercializing and offering liquid biopsy products and services to the market.
These procedures, for the most part, query blood samples for information to be gleaned from circulating tumor cells (CTCs), circulating tumor DNA (ctDNA) fragments, and extracellular vesicles (EVs). CTCs have the longest history as subjects for liquid biopsy. Indeed, one decade-old commercial product has already garnered FDA approval for in vitro diagnostic use. Circulating tumor DNA, a more recent entry on the liquid biopsy scene, is fast becoming an alternative or adjunct to CTC assays. EVs are the newest and least developed of the three liquid biopsy sample sources, and while highly promising; their ultimate value has yet to be fully established.
The report delves deeply into recent progress and emerging trends in this highly dynamic area of research and commerce. Following an introductory chapter that sets the stage for what is to follow, Chapter 2 provides a survey of historical and evolutionary aspects of liquid biopsy, and provides required background and definitions helpful in understanding subsequent material. Chapter 3 covers basic research activities arranged according to the three aforementioned analyte classes (CTCs, ctDNA, and EVs).
CTCs, the first such entities on the liquid biopsy scene, have accounted for much of what’s been learned to date. However, the relative ease of isolating cell-free DNA has quickened research activity in this field, and ready access to ctDNA has provided important insights that enhance and complement those derived from CTCs. EVs, though a recent arrival on the liquid biopsy scene, are rising rapidly in importance based on their perceived ability to add yet another important perspective to cancer diagnostics.
