There was also a significant difference in EGFR (Figure 1F–G–H) and VEGF (Figure 1J–K–L) expressions between G I and II tumours (p = 0.02 and p = 0.05, respectively) and between G II and III tumours (p = 0.01 and p = 0.04, respectively) (Table 2). The gene discussed is EGFR; the disease is neoplasm.
