Association and prognostic significance of alpha-L-fucosidase-1 and matrix metalloproteinase 9 expression in esophageal squamous cell carcinoma

Figure 3 Immunohistochemical staining for alpha-L-fucosidase-1 and matrix metalloproteinase 9 in esophageal squamous cell carcinoma. A: Stage IA esophageal squamous cell carcinoma (ESCC) with negative expression of alpha-L-fucosidase-1 (FUCA1) (total score, 0); B: Stage IIB ESCC with low expression of FUCA1 (total score, 2); C: Stage IIB ESCC with high expression of FUCA1 (total score, 12); D: Stage IB ESCC with negative expression of matrix metalloproteinase 9 (MMP-9) (total score, 0); E: Stage IB ESCC with low expression of MMP-9 (total score, 3); F: Stage IIIA ESCC with high expression of MMP-9 (total score, 12).
