ABSTRACT
OBJECTIVE@#To investigate the expression of Survivin and its relationship with the expression of Bcl-2 in sinonasal inverted papilloma (SNIP).@*METHOD@#Immunohistochemical method was used to determine the expression of Survivin and Bcl-2 in 30 cases of SNIP, 10 cases of sinonasal squamous cell carcinoma (SCC) and 10 cases of normal inferior concha tissues.@*RESULT@#Survivin was expressed in 22 of 30 (73.3%) cases of SNIP, 8 of 10 (80.0%) cases of SCC and not expressed in 10 (0%) cases of normal inferior concha tissues. Expression of Survivin was significantly higher in SNIP and SCC than in normal tissues. Bcl-2 was expressed in 9 of 10 (90.0%) cases of SCC and 2 of 10 (20.0%) cases of normal inferior concha tissues. Expression of Bcl-2 was significantly higher in SCC than in normal tissues. Bcl-2 was expressed in 14 of 30 (46.7%) cases of SNIP, higher than normal tissues. Expression of Bcl-2 was positively related to expression of Survivin.@*CONCLUSION@#Survivin may play an important role in the pathway of progression of SNIP and SCC. It may be identified as a new therapeutic target. Bcl-2 may play a synergic role with Survivin in progression of SNIP.

Objective:To investigate the expression of Survivin and it's relationship with the expression of Bcl-2 in sinonasal inverted papilloma (SNIP).Method:Immunohistochemical method was used to determine the expression of Survivin and Bcl-2 in 30 cases of SNIP,10 cases of sinonasal squamous cell carcinoma(SCC) and 10 cases of normal inferior concha tissues.Result:Survivin was expressed in 22 of 30(73.3%)cases of SNIP,8 of 10(80.0%)cases of SCC and not expressed in 10(0%)cases of normal inferior concha tissues.Expression of Survivin was significantly higher in SNIP and SCC than in normal tissues.Bcl-2 was expressed in 9 of 10(90.0%)cases of SCC and 2 of 10(20.0%)cases of normal inferior concha tissues.Expression of Bcl-2 was significantly higher in SCC than in normal tissues.Bcl-2 was expressed in 14 of 30(46.7%)cases of SNIP,higher than normal tissues.Expression of Bcl-2 was positively related to expression of Survivin.Conclusion:Survivin may play an important role in the pathway of progression of SNIP and SCC.It may be identified as a new therapeutic target.Bcl-2 may play a synergic role with Survivin in progression of SNIP.
