In 1976, zur Hausen postulated that HPV played a role in anogenital carcinoma. Until advances were made in molecular biology with hybridization techniquesĭiscovery of Nonpapillomatous HPV-Associated Genital Lesions Or to transfer it to suitable animal hosts, further progress was slow 4 Because it was, until recently, impossible to grow HPV in tissue culture Shown to induce rabbit papillomas that developed into malignant squamousĬell carcinomas when exposed to chemical mutagens and radiation. 3 The cottontail rabbit papillomavirus was later named after Shope and was Nature of warts by infecting rabbits with papilloma extracts from wildĬottontail rabbits. Theįormation of the neoplasms was not interpreted as being related toĪn infectious event until Shope, in 1933, demonstrated the infectious Of the vulva and penis were first reported in the 19th century. Isolated cases of conversion of genital warts into squamous cell carcinomas In some squamous cell carcinomas of the skin, tongue, oral cavity, hypopharynx, larynx, and lung. 1 DNA of specific HPV types also has been found outside the anogenital sphere In women, with 460,000 cases diagnosed each year. Importance among anogenital cancers because it is the most common cancer That HPV contributes to about 10% of the worldwide tumor burden and up STRUCTURE AND GENOMIC ORGANIZATION OF PAPILLOMAVIRUSESĭuring the past 20 years, a large number of studies have shown a strongĪssociation between the presence of specific types of human papillomavirus (HPV) and Northern Virginia Pelvic Surgery Associates, PC, Annandale, virginia Co-director of Gynecologic Oncology, Department of Obstetrics and Gynecology, The Fairfax Hospital, Falls Church, Virginia Clinical Professor, Department of Obstetrics and Gynecology, George Washington University Hospital, Washington, DC ( Vol 4, Chap 30) Human Papillomavirus Infection and Genital Tract Cancer
