Ricerca di HPV-DNA e tipizzazione virale nella diagnostica di prevenzione del carcinoma della cervice uterina
AbstractPapillomaviruses are relatively ubiquitous and have been described as causative agents for epithelial lesions in a wide variety of animals as well as in humans. Approximately 30 HPV types have been isolated from anogenital epithelium (cervix, vagina, vulva, rectum and penis). HPVs induce a variety of proliferative lesions, but only the “high-risk” types are associated with anogenital cancers. “Low-risk” viral types include HPV-6 and HPV-11; “high-risk” types include HPV-16, 18, 31 and 56. HPVs “high-risk” types are more strongly associated with high-grade lesions (HSIL) than they are with low-grade lesions (LSIL). The traditional process for cervical cancer screening programs (PAP test) is vulnerable to air drying artifacts and has limits to sensitivity, since as many as 90 percent of collectet cells can be discarted with collection device. The present study was undertaken to assess the screening performance of HPV-DNA typing in a sample of 142 women drawn from a routine screening for the prevention of cervical cancer. The results indicate that HPV-DNA screening and typing, used together with PAP test, can improve the detection of patients with cervical disease and can serve as a quality assurance indicator in cervical cancer screening programs.
