Objective To investigate HPV infection and its correlation with the expression of sur- vivin and proliferating cell nuclear antigen (PCNA) in condyloma acuminatum (CA).Methods HPV6/11 and 16/18 DNA were detected by PCR in 41 cases of CA and 23 specimens of normal skin.The expression of survivin and PCNA was measured by immunohistochemical technique in these two groups. Results The infection rates of HPV6/11 and 16/18 were 87.80% (36/41) and 19.51%(8/41),respective- ly,in CA,and 0 in normal skin epidermis.The expression of survivin and PCNA was found in 53.66% (22/41) and 87.80% (36/41) of CA ,and was 8.70%(2/23)and 47.83% (11/23) in normal skin,respec- tively.The expression of survivin was positively correlated with the high expression of PCNA in CA.The expression of survivin and PCNA was higher in HPV6/11 positive lesions than in HPV6/11 negative lesions. Conclusion HPV infection may up-regulate the expressions of survivin and PCNA,inhibit the apoptosis and promote the proliferation of keratinocytes.
