ALDH2 polymorphism for the risk of cervical carcinogenesis

To investigate the clinical significance of ALDH2 genetic polymorphisms in cervical carcinogenesis. ALDH2 polymorphisms together with human papillomavirus (HPV) types were examined in a total of 195 cervical smear in exfoliated cervical cell samples using Real-Time polymerase chain reaction (PCR) System. The frequency for the AG+AA genotype was seven in the normal group (70.0 %), 16 in the LSIL group (57.1 %), and 27 in the HSIL group (90.0 %). A significant difference was found between the LSIL and HSIL groups (P = 0.0064). Patients with HSIL lesions frequently had high-risk HPV infections and concurrently belonged to the AG+AA group. ALDH2 genotype in cervical cell samples may be associated with more severe precancerous lesions of the cervix in a Japanese population.     

Germline polymorphisms of glutathione-S-transferase GSTM1, GSTT1 and p53 codon 72 in cervical carcinogenesis

The clinical significance of glutathione-S-transferase GSTM1, GSTT1 and p53 codon 72 polymorphisms in cervical carcinogenesis was investigated. Germline polymorphisms of GSTM1, GSTT1 and p53 codon 72 together with human papillomavirus (HPV) types were examined in a total of 457 blood and cervical smear samples from normal healthy women and the patients with premalignant and malignant cervical lesions. The 167 patients with low-grade squamous intraepithelial lesion (LSIL), 49 with high-grade SIL (HSIL) and 83 with squamous cell carcinoma (SCC) had significantly higher frequency of high-risk HPV than 158 controls. The 49 patients with HSIL and 83 with SCC had statistically higher frequency of null GSTT1 genotype than 158 controls. There was an increased odds ratio for null GSTT1 genotype in HSIL and SCC cases compared with controls among 191 patients with high-risk HPV. The 67 cases with HPV types 16 and/or 18 had higher frequency of the GSTT1 null genotype than 186 with other types of HPV. There was no statistical difference in the polymorphic frequency of GSTM1 and p53 codon 72 genotypes between SILs and controls with or without high-risk HPV. These results suggest that GSTT1 null genotype may increase the risk of cervical cancer particularly in the cases with high-risk HPV types in a Japanese population.     

Prevalence of human papillomavirus among Croatian women attending regular gynecological visit

Human papillomavirus (HPV) infection has been identified as major risk factor for cervical intraepithelial neoplasia (CIN) and invasive cervical cancer. About 40 HPV viral types are commonly found in the genital tract. Most HPV infections resolve spontaneously, while persistent infection with oncogenic types, namely HPV 16 and 18 is necessary for CIN to occur and progress to cancer. Cervical screening is presently based on the Pap smear that is designed to diagnose precancerous lesions and cervical cancer The aim of this study was to investigate the prevalence of HPV DNA and to determine HPV types distribution among 361 women attending regular gynecological visit. There were 205 women (29+/-8 years old) without determined abnormal cervical lesions and 156 women (34+/-15 years old) with abnormal Pap smear; low grade squamous intraepitehelial lesions (LSIL, n=69), high grade squamous intraepithelial lesions (HSIL, n=72) and atypical squamous cells of undetermined significance (ASCUS, n=15). HPV DNA detection and genotyping was performed by Hybrid Capture 2 assay and additionally by consensus and type-specific primers directed PCR. The overall prevalence of high-risk HPV (hrHPV) in women with abnormal Pap smears was 67.9% (106/156), of which in ASCUS 33.4% (5/15), LSIL 62.3% (43/69) and HSIL 80.6% (58/72). In HPV positive specimens, HPV 16 was found as predominant type in 60.4% cases, followed by HPV 31 (8.5%), HPV 33 (6.6%) and HPV 18 (3.7%). In the group of women without obvious cervical changes the overall hrHPV prevalence was 35.6% with HPV 16 found in 43.8% cases, followed by HPV 31 (17.8%), HPV33 (9.5%) and HPV18 (6.8%). In both study groups, women with and without cervical lesions, the prevalence of HPVof indeterminate type was 14.2% and 13.7%, respectively. Our results indicate that cervical intraepithelial lesions are largely associated with HPV type 16, followed by HPV types 31, 33, 18 and HPV of indeterminate type. Although there is a significant difference in hrHPV DNA prevalence among two groups, no significant differences between particular hrHPV types distribution were observed.     

Prevalence of human papillomavirus infection and genotype distribution determined by the cyclic-catcher melting temperature analysis in Korean medical checkup population

Although cytology screening has reduced the incidence and mortality rate of cervical cancer significantly, its usefulness is limited to samples from the site of the lesion, resulting in its low sensitivity and unsuitability for use in medical checkups. The purpose of the present study was to evaluate the prevalence of HPV infection using genotype distribution and to analyze the correlation of the HPV DNA test results with cytological results. We also evaluated the benefits of quantitative information obtained from cyclic-catcher melting temperature analysis (CMTA) in screening for cervical cancer. We performed cyclic-CMTA using Anyplex? II HPV28 Detection in combination with cervical cytology for 2,181 subjects. The following HPV positivity types were detected using cyclic-CMTA and HPV positivity was found to increase together with the severity of the cytology results: (1) For 419 HPV positive specimens, HPV DNA was detected in 18.1% of normal specimens, 78.3% of ASCUS, and all of LSIL and HSIL; (2) high-risk HPV DNAs were detected in 63.3% of normal (N=547), 65.9% of ASCUS (N=41), 76.9% of LSIL (N=13), and 88.9% of HSIL (N=9) among total detected HPV DNA regardless multiple detection; (3) multiple HPV genotypes were detected in 4.8% of normal specimens (N=2,146), 52.2% of ASCUS (N=23), 57.1% of LSIL (N=7), and 40.0% of HSIL (N=5). In addition, a high level of viral DNA was observed using cyclic-CMTA in all specimens beyond the LSIL stage according to cytology, while only 6% of specimens with normal cytology showed a correlation with viral quantitation by cyclic-CMTA. The combination of HPV genotyping with a quantitative assay and cytology will allow for a more accurate diagnosis of cervical cancer.

Retrospective study of the prevalence of high-risk human papillomaviruses among Croatian women

The infection with Human papillomavirus (HPV) is the necessary cause for cervical cancer. There are at least 15 High-Risk (HR) HPV types that are significantly associated with progression of cervical intraepithelial neoplasia to cervical cancer. Since previous studies showed that the prevalence of HPV in cervical cancers varies among different geographic regions, we wanted to investigate the prevalence of HPV types in Croatia, especially low abundant HR HPV types. By means of consensus primers directed polymerase chain reaction (PCR), we analysed cervical DNA samples of 2,136 Croatian women, mostly with abnormal cervical smears, in order to detect the presence of HPV Type-specific primers were then used to determine Low-Risk (LR) HPV types 6/11 and HR HPV types 16, 18, 31, 33, 45, 52 and 58. Out of 2,136 specimens, 1,255 (58.8%) were positive for HPV More than half of positive samples were typed (64.5%) and 35.5% still remained untyped. Multiple HPV infections were found in 10.3% of the cases. The most prevalent type, including both single and multiple infections, was HPV16 with the prevalence of 15.9%, followed by HPV types 31, 6/11, 33, 18, 52, 45 and 58 with 8.7%, 7.1%, 4.5%, 3.8%, 2.3%, 1.2% and 1.1%, respectively. The significant increase of frequency from Low-grade Squamous Intraepithelial Lesions (LSIL) to High-grade Squamous Intraepithelial Lesions (HSIL) was observed for HR HPV types 16, 18, 31 and 33 but not 45, 52 and 58. The frequency of unknown HPV types was almost the same in cervical specimens of women with LSIL and those with HSIL, 19.8% and 21.1%, respectively. The prevalence of HPV infection rate decreased significantly with patient age from 68.5% (age group 12 to 24 years) to 38.8% (age group 45 to 54 years). But, in women aged 55 or older the overall prevalence increased to 56.6%. Our results indicate that prevalence of HR HPV types in Croatia is similar to other countries. We suggest that HPV positive women in Croatia should be closely monitored by typing for HR HPV types: 16, 18, 31, 33, 45, 52 and 58.     

Immunocytochemical detection of HPV high-risk type L1 capsid proteins in LSIL and HSIL as compared with detection of HPV L1 DNA

OBJECTIVE: To investigate the prevalence of HPV L1 capsid proteins in HPV-infected HSIL and LSIL. STUDY DESIGN: Cervical smears from 74 women with cytologically and histologically confirmed LSIL (n = 32) and HSIL (n = 42) were collected prospectively to detect HPV high-risk (hr) types 16, 18, 33, 35, 39, 45, 56 and 58 L1-DNA by standardized L1-consensus primer PCR (MY 09/11) and L1 capsid proteins by immunocytochemistry using monoclonal antibodies T31 (HPV16) and T16 (HPV hr) in a standardized protocol. RESULTS: In HSIL and LSIL, L1 DNA was found for HPV hr in 93% and 59% and for HPV16 in 69% and 37% of the specimens, respectively. HPV L1 capsid proteins were detected in HSIL and LSIL for HPV hr in 33% and 44% and for HPV16 in 29% and 31% of the specimens, respectively. Expression of L1 capsid proteins was significantly reduced, by 59.6% for HPV hr L1 DNA-positive HSIL (P < .01) and by 40.4% for HPV 16 L1 DNA-positive HSIL (P < .01). In HPV 16 DNA-positive and HPV hr DNA-positive LSIL, no significant reduction of corresponding L1 capsid protein expression could be demonstrated. CONCLUSION: These data suggest a disturbed viral cellular interaction in HPV 16 and HPV hr-infected HSIL, with loss of viral L1 capsid antigen. In this context there is a possible role of T31 and T16 as prognostic markers to predict the prognosis of CIN.

目的:探讨乳头瘤病毒定性检测( HPV- DNA)与液基薄层细胞学检查技术(TCT)在宫颈癌前病变中的诊断价值.方法:分别采用HPV- DNA及TCT法检测1536例患者,对TCT阳性、HPV- DNA阳性病例者进行阴道镜下活检.结果:随着病理诊断级别的升高,高危型HPV感染率上升,而低危型HPV感染多见于轻度不典型增生(CINⅠ)及其以下病变,HPV混合感染在各组间未见明显趋势.HPV-DNA检测与宫颈活检的符合率为66.78％.随着病理级别的升高,不典型鳞状细胞(ASCUS)组的感染率呈降低趋势,鳞状上皮内低度病变(LSIL)组感染率亦呈下降趋势,而鳞状上皮内高度病变(HSIL)组和鳞癌(SCC)组感染率均呈上升趋势,TCT检测与组织学诊断的符合率为66.67％,与HPV-DNA检查比较,差异无统计学意义(x=0.001,P＞0.05).结论:HPV-DNA、TCT及宫颈活检三者检测相结合,能明显提高诊断的正确性.
