Beta-Catenin and Epithelial Tumors: A Study Based on 374 Oropharyngeal Cancers
Figure 2
Persistent detection of membranous staining for beta-catenin (a)–(d) and sporadic nuclear staining for beta-catenin (e)–(h). Membranous expression of the study marker was more observable in the lip and palate carcinomas (M, ) (a), in <2 cm tumor () (b), and in well-differentiated cancers () (c), in early stage (St I) tumours () (d). Sporadic nuclear positivity for beta-catenin was more observable in <2 cm tumor () (e), in early stage (St I) tumours () (f), without nodal metastases (N0) () (g), and with a better clinical followup () (h).
