The average expression level of the ABCA3 (p = 0.007), ABCB9 (p = 0.000), ABCC1 (p = 0.000), ABCC4 (p = 0.000), ABCC5 (p = 0.000), and ABCC6 (p = 0.000) genes was statistically significantly higher in patients without tumor cell infiltration in the lymph vessels (Figure 6). Here, ABCC6 is linked to neoplasm.
