On day 9 after MWA, the abscopal tumor volume in the MWA group (990.167 ± 321.343 mm3) was less than that in the control group (1513.833 ± 331.515 mm3) (p < 0.001, Figure 2C), suggesting that MWA at 3 w–3 min activated the abscopal effect in CT26 tumor-bearing mice. This evidence concerns the gene DDX53 and neoplasm.
