ABSTRACT
OBJECTIVE: To analyze the infection condition of human papillomavirus (HPV) type 16 and 18 in the squamous cells and columnar cells of patients with common anorecatal lesions. METHODS: Infections of HPV type 16 and 18 were determined with real-time fluorescent quantitative PCR in the wax-embedded surgical specimen of 805 patients with common anorectal diseases. RESULTS: The overall infection rate among 805 patients with anorecatal lesions was 66.1% (532/805). The infection rate was 82.6% (95/115) in patients with mixed hemorrhoids, 76.5% (88/115) in anal papillary fibromas, 74.8% (86/115) in internal hemorrhoids, 72.2% (83/115) in fistulas, 69.6% (80/115) in external hemorrhoids, 47.8% (55/115) in anal perianal abscesses, and 39.1% (45/115) in anal fissures. CONCLUSION: Infection rate of HPV type 16, 18 in common anorectal lesions is high.
