Figure 3. Dose- and time-dependent increase in plasma cfDNA levels in stage IV NSCLC patients in response to radiotherapy.
(A) Plasma cfDNA levels in stage IV NSCLC patients (cases 12–17) in response to different irradiation doses are shown. (B) Plots show time course of plasma cfDNA levels in stage IV NSCLC patients (cases 12–17) before (pre-RT) and after radiation therapy.
