Abstract

We determined the prevalence of human papillomavirus (HPV) by DNA chip test in 549 women and cytologic diagnosis. 237 of 549 women (43.17%) subjected with HPV DNA Chip examination were found positive for HPV. 210 (88.60%, High group) were infected with high-risk HPV types. 17 (7.17%, Low group) were infected with low-risk HPV types (6, 11, 40, 44, 70) and 17 (7.17%, Mixed group) were infected with mixed types. According to age, in their twenties, thirties, forties, fifties and over sixties, the prevalence of infection with high-risk HPV types were 1.26% (3/237), 15.61% (37/237), 31.65% (75/237), 23.21% (55/237), and 13.92% (33/237), respectively. In the Low and Mixed group, percentages of infection with HPV were significantly lower than that of the High group. On the comparison of cytologic diagnosis (224 women) by Pap smear and DNA chip positive (237 women) for HPV, 132 out of 194 cases in the High group (68.04%) suffered cervical lesions with ASCUS (atypical squamous cells of undetermined significance, 7.22%), LSIL (low grade squamous intraepithelial lesion, 15.98%), HSIL (high grade SIL, 23.20%) and ICC (invasive cervical cancer, 21.65%). The Low group (14/224 women) showed 1 case of ASCUS and 6 cases of LSIL, whereas the Mixed group (4/224 women) had only 2 cases of ASCUS. According to the HPV subtypes, the high-risk types 16 and 18 induced 26 and 7 cases of ICC, respectively, whereas other HPV subtypes induced lower or no ICC incidence. In conclusion, the present data imply that the prevalence of HPV was 43.17%, high-risk HPV type 16 is a major factor, which causes precancerous and/or cervical cancer in woman and that HPV DNA chip is an accurate and useful tool for detecting HPV.

우리는 549명의 여성을 대상으로 HPV DNA Chip을 이용하여 자궁경부암의 주요 원인인 HPV 감염률을 조사하고 Pap 도말 염색법을 이용한 세포학적 검사를 실시하였다. 전체 대상여성 549명 중 237명 HPV DNA Chip 검사에서 양성 이었다(43.17%). 237명 중 203명이 고위험군 HPV 아형에 감염되었고(88.61%, 고위험군), 17명이 저위험군 HPV 아형에 감염되었고(7.17%, 저위험군), 나머지 17명은 고위험군 아형, 저위험군 아형, 미확인 아형에 감염 되었다(7.17%, 혼합형). 연령별 감염률은 20대가 1.26%, 30대 15.61%,40대 31.65%, 50대 23.21%, 60대 이상이 13.92%으로 확인되었다. 저위험군과 혼합군에서 고위험군보다 HPV 감염의 빈도가 더 낮게 나타났다. 세포학적 진단결과(224명의 여성)와 HPV chip 양성(237명의 여성)여성 간의 비교에서 고위험군의 경우 194명중 132명(68.04%)이 ASCUS (atypical squamous cells of undetermined significance, 7.22%), LSIL (low grade squamous intraepithelial lesion, 15.98%), HSIL (high grade SIL, 23.20%), 자궁경부암(21.65%) 등과 같은 자궁경부질환이 있었다. 저위험군(224 여성 중 14명)의 경우 ASCUS 1예와 LSIL 6예였는데 비해 혼합군(224 여성 중 4명)의 경우에는 단지 2예의 ASCUS 만이 있었다. 고위험 HPV 아형16 및 18에 감염된 여성은 각각 26예 및 7예의 자궁경부암이 있었으나 저위험군 HPV 아형 및 기타 아형의 경우 자궁경부암 발생이 매우 낮거나 없었다. 결론적으로 본 연구에서 43.17%의 HPV 유병률을 보였고 고위험 HPV 아형16이 감염된 여성들에 있어 전암 병변 또는 자궁경부암의 원인이 되는 주요인자이며 HPV DNA chip 검사는 HPV 감염 유무를 진단하는 정밀하고 유용한 방법임을 시사하고 있다.
