Keratins 6, 13 and 19. Differential expression in @entity957 of the XXXX .

@entity135 @entity4166 @entity5 @entity957 @entity189 @entity7435
One hundred forty-one @entity135 @entity957 were analyzed for keratin (K) 6, 13 and 19. Staining was evaluated by light microscopy (with or without grading) and image analyzer and expressed as a percentage of positive versus all @entity5 surface (PSA). Both techniques rendered strongly correlated results. Strong expression was noted in 108 @entity189 (76.1%) for K6, in 18 (12.7%) for @entity4166 and in 21 (14.8%) for @entity7435 (P = .001). One hundred thirty-six (96%) @entity5 were positive for K6, and their PSA ranged from 0.6% to 48.8%; @entity4166 , 48 cases (0.2-44%); @entity7435 , 59 (0.2-38.1%). Expression of K6 was related to differentiation. @entity4166 was expressed mainly in moderately and poorly differentiated @entity5 , and @entity7435 was manifest more in well-differentiated @entity189 or in keratinized areas of less-differentiated ones. Nineteen (13.38%) @entity5 were positive for both @entity7435 and @entity4166 . @entity4166 thus was related to @entity5 progression and @entity7435 to differentiation. There was no correlation with @entity5 site or TNM category.
