Objective:To explore the expressions of c-fos and c-myc in skin lesion of cutaneous squamous cell carcinoma(CSCC).Methods:Using retrospective analysis.73 cases of CSCC were selected from Department of Dermatology,the Second Affiliated Hospital of Xi’an Jiaotong University.which were removed between January 2000 and January 2012.It was considered as experimental group.Meanwhile.11 cases of normal skin specimens of non tumor patients were selected as control group.The expression level of c-fos and c-myc was compared in the two groups.Results:The expressions of c-fos[72.60%(53/73)]and c-myc[83.56%(61/73)]in experimental group were statistically significant(P≤0.05)compared with control group(0%).Expression of c-myc protein was negatively related to differentiation of CSCC.The difference was statistically significant(X~2=7.26.P=0.001<0.05).While expression of c-fos protein was positively related to differentiation of CSCC.which was statistically significant(X~2=7.47,P=0.0012<0.025).Conclusions:The expression level of c-fos and c-myc can be used as an importan indicator of CSCC differentiation,and it has closely connection with the differentiated degree,which can guide clinical prognosis.
Objective: To explore the expressions of c-fos and c-myc in skin lesion of cutaneous squamous cell carcinoma (CSCC). Methods: Using retrospective analysis. 73 cases of CSCC were selected from Department of Dermatology, the Second Affiliated Hospital of Xi ’ an Jiaotong University. Which were removed between January 2000 and January 2012. It was considered as experimental group. Min. 11 cases of normal skin specimens of non-tumor patients were selected as control group. The expression level of c-fos and c-myc were compared in the two groups. Results: The expressions of c-fos [72.60% (53/73)] and c-myc [83.56% (61/73)] in experimental group were statistically significant (P ≦ 0.05) compared with Control group (0%). Expression of c-myc protein was negatively related to differentiation of CSCC. The difference was statistically significant (X ~ 2 = 7.26.P = 0.001 <0.05) .While expression of c-fos protein was positively related to differentiation of CSCC.which was statistically significant (X ~ 2 = 7.47, P = 0.0012 <0.025) .Conlu sions: The expression level of c-fos and c-myc can be used as an importan indicator of CSCC differentiation, and it has closely connection with the differentiated degree, which can guide clinical prognosis.
