ctDNA
What is ctDNA? Circulating tumor DNA (ctDNA) is cell free DNA- dsDNA and mtDNA- from tumor cells that can be found in the plasma of cancer patients.
What is ctDNA used for?
ctDNA has growing applications as liquid or blood biopsies for:
- Evaluating mutations in tumor cells.
- Monitoring response to treatment.
- Monitoring changes to the tumor as the half-life of ctDNA is from 30 minutes to two hours.
- Use as a surrogate to assess tumor stage, size, and aggressiveness, based on the concentration of the ct DNA and the number of somatic changes.
- Possible advancements in cancer screening.
- Companion diagnostics
- Identification of possible treatment targets
