Fig. 4

Demonstrates the fluctuations of ctDNA with respect to tumor and nodal volumes during the course of the experiment. The vertical dotted lines indicate the days that rabbits underwent radiation. Plasma ctDNA shows a good correlation with primary tumor volumes and mirrors closely the pattern of tumor volume. Plasma ctDNA elevation is noted during the initiation of radiation in both first and second cycles
