ERBB2 and neoplasm: Tumor volumes in the HER2/neu group remained relatively low, with a mean volume of less than 50 mm3 by day 45, representing a statistically significant reduction compared to both the Control and LV-neg groups (p< 0.05 and p< 0.0001, respectively, Kruskal-Wallis with Dunn’s post-hoc test; Figure 4B) with no statistically significant differences observed between the Control and LV-neg groups.
