ABSTRACT
Objective To explore the role of humall papillomavims (HPV) type 16 E6 variants in the persistent infection and recurrence of the cervical high-grade squamous intraepithelial lesion (HSIL) after conization. Motheds During May to June 2012, 100 HSIL patients with HPV16 positive but negative at the margin after Loop electrosurgical excision procedure (LEEP) were selected from Shanghai People′s Hospital of Pudong District. The gene sequencing was done to the E6. The patients were followed up for 2 years. The E6 gene sequencing was done again to detect the HPV16 variants among those with persistent infections and recurrence. Results Among the 100 cases, E6 variants were detected, 81% of them HPV E6 variants Asian prototype, 14% European variant; 2% European prototype (EP) and 3% African variant 1. LEEP for Asian prototype was susceptible to the clearance of HPV16 (P < 0.001). The European variants of T350G, and A442C were correlated with persistent infection and recurrence (P < 0.001). Conclusion The HPV16 variant is closely related to the HSIL incidence. HSIL caused by HPV16 in Pudong New Area of Shanghai belong to the Asian type variant. The European variants of E6 , T350G/A442C were likely related to the recurrence of HPV16.
