Liquid Biopsies for Molecular Biology-Based Radiotherapy

Area of Science:

• Oncology
• Molecular Biology
• Radiotherapy

Background:

• Cancer initiation and progression are driven by molecular alterations.
• Personalized radiotherapy requires understanding tumor biology and individual risk.
• Circulating nucleic acids offer a non-invasive method for biomarker analysis.

Purpose of the Study:

• To explore the potential of liquid biopsies beyond biomarker discovery.
• To investigate tumor clonal evolution and acquired resistance using ctDNA.

Main Methods:

• Analysis of circulating tumor DNA (ctDNA).
• Application of liquid biopsy techniques.
• Translational research into tumor evolution and resistance mechanisms.

Main Results:

• Circulating tumor DNA analyses are powerful tools for precision radiotherapy.
