The spectrum and clinical sequelae of human papillomavirus infection

Abstract

Infection with the human papillomavirus (HPV) is the most common sexually transmitted disease afflicting approximately 80% of the population. HPV infection is an essential factor in cervical carcinogenesis and cervical carcinoma is the second most common cause of cancer among women worldwide. In addition to cervical cancer, other malignancies in both men and women such as esophageal, oropharyngeal, and anal cancer have been causally associated with this virus. Other gender-specific HPV-related cancers include penile, vulvar and vaginal cancer. HPV-16 is the most common HPV type associated with a malignant phenotype regardless of organ of origin. HPV-16 together with HPV-18 accounts for approximately 70% of cervical cancers. Other non-oncogenic HPV types including HPV types 6 and 11 are associated with over 90% of benign HPV-related lesions such as genital warts and juvenile respiratory papillomatosis. © 2007 Elsevier Inc.
