Abstract:
Objective To study the clinicopathological significance of Skp2 and E2F1 in the rhinosinus squamous cell carcinoma and chronic sinusitis. Methods Immunohistochemical method was used to detect the expression of Skp2 and E2F1 in the routinely paraffin-embed-ded sections of specimens from patients with rhinosinus squamoas cell carcinoma (n=49), chronic sinusitis (n=28). Results The expres-sive positive rates and scores of Skp2 and E2F1 in rhinosinus sqnamous cell carcinoma were significantly higher than those in chronic sinusitis (P<0.01). The expression positive rates and scores were significantly decreased in middle-differentiated rhinosinus squamous cell carcino-ma. The maximal diameter of mass was less than 3cm, and no-metastasis of lymphnode or no-infiltration of regional rhinosinus can be found in T1N0M0. While in the low-differentiated rhinosinus squamous cell carcinoma, the maximal diameter of mass was larger than 3cm, and metasta-sis of lymphnode or infiltration of regional rhinosinus can be found(T3N1M0,T3N2M0) (P<0.01). The closely positive correlation was found between the expression of Skp2 and E2F1 in the rhinosinus squamoas cell carcinoma. Conclusions Skp2 and E2F1 might be important biologi-cal markers for carcinogenesis, progression, biological behaviors and prognosis of rhinosinus squamous cell carcinoma.
