There was a 96.5% average reduction in the tumor volume for the group treated with the combination of HisDianthin‐EGF and SO1861 compared to the placebo (tumor volume 84.5 ± 51.9 mm3 for placebo and 3.0 ± 3.3 mm3 for combination) and four of five mice showed complete regression (Fig. 5). Here, EGF is linked to neoplasm.
