  1. Human papillomavirus and cervical neoplasia : a case-control study in Taiwan.

    Article - En anglais

    As part of a large-scale, community-based cervical neoplasia screening project in rural Taiwan, a case-control study was undertaken to evaluate the etiologic role of human papillomavirus (HPV) infection in this mainly monogamous (2% reported having multiple sexual partners) female population.

    A total of 88 biopsy-confirmed cases and 261 cytologically normal controls were selected for the study.

    The case group included 40 cases of cervical intraepithelial neoplasia (CIN) 1,9 of CIN 2,36 of CIN 3 and 3 cases of invasive cancer.

    Cervical swabs collected at screening from study subjects were tested for HPV DNA by an LI consensus primer polymerase chain reaction (PCR) - based technique.

    HPV DNA was found in 92% of high-grade cases (CIN 2-3 and invasive cancer) ; 54% of low-grade cases (CIN 1) ; and 9% of controls.

    HPV was significantly associated with both high-grade and low-grade cervical neoplasia.

    As reported in Western countries, HPV 16 was the predominant type among HPV-positive high-grade cases.

    However, HPVs 52 and/or 58 combined were the most common types among HPV-positive low-grade cases and controls.

    Among women without any high-risk HPV infection (types 16,18,31 or 45), those with multiple-type HPV infection had a higher risk for high-grade cervical neoplasia than those with single-type infection.

    Our results show that, even in this monogamous population, HPV is the major risk factor for high-grade cervical neoplasia.
