[The expression of Smac and survivin in sinonasal inverted papilloma].

Abstract

OBJECTIVE:

To explore the expression of Smac(second mitochondria-derived activator of caspase)and survivin on the growth, development, recurrence and carcinogenesis of the sinonasal inverted papilloma(NIP).

METHOD:

Immunohistochemical method was used to detective the expression of Smac and survivin in 10 cases of (nasal cavity mucosae, NM), 45 cases of NIP. The NIP group including 25 cases of NIP without dysplasia, 11 cases of NIP with dysplasia, and 9 cases of NIP with malignant transformation to squamous cell carcinoma(SCC).

RESULT:

The intensity of the positive expression of Smac in NIP was lower than NM, the intensity of the positive expression decreased with the decreasing degree of histological differentiation. There was significantly difference between NIP without dysplasia and SCC. The expression of survivin was negative in the control group, the expression intensity of NIP was enhanced. The degree of histological differentiation was lower, the intensity of the positive expression was higher. The expression between NIP without dysplasia and SCC had significantly differences. Smac negatively correlated with survivin(rs = -0.403, P<0.01).

CONCLUSION:

Smac and survivin were associated with the growth and carcinogenesis of NIP.
