Prevalence and Distribution of High Risk Human Papillomavirus(HPV) Types 16 and 18 in Carcinoma of Cervix,Saliva of Patients with Oral Squamous Cell Carcinoma and in the General Population in Karnataka,India

Background: In view of conducting HPV vaccination in India it is most important to understand the prevalenceof HPV genotypes in this population, not only in squamous cell carcinoma of cervix and oral cavity but also inthe general population. In this study we explored the prevalence and distribution of high-risk HPV types 16 and18 in carcinoma of cervix, saliva of patients with oral squamous cell carcinoma and in general population inKarnataka. Methods: Cervical cancer specimens after punch biopsy (n=60) were obtained from women attendingKarnataka Institute of Medical Sciences and Karnataka Cancer Therapy and Research Institute, Hubli (KCTRI).Saliva rinse of (n=34) OSCC patients from KCTRI and (n=396) normal individuals from different regions ofNorth Karnataka, were collected and PCR based high-risk HPV genotyping was carried out. Results: Usingconsensus PCR primers it was observed that 96.7% patients were infected with HPV irrespective of specific typein cervical cancer. Among them, HPV 16 was observed in 89.7%, HPV 18 in 86.2% and both HPV 16 and 18 in79.3% patients. In OSCC, 70.6% were positive for HPV, among which HPV 16 prevalence was observed in 45.8%,HPV 18 in 54.2%, and HPV 16 and 18 multiple infection in 4.18%. In general population, HPV prevalence wasobserved in 84.4%. Among them, HPV 16 was observed in 2.75% and HPV 18 in 22.0% patients. In generalpopulation, multiple infection with HPV 16 and 18 was not observed but 75.3% were found to be infected byHPV genotypes other than HPV 16 & 18. Conclusions: Our study reveals that multiple infection of HPV 16 and18 is quite high in cervical cancer and in case of OSCC, it was in conformity with the other studies. In generalpopulation HPV 18 prevalence was observed to be high. With this, we can conclude that both HPV 16 and 18vaccinations will reduce the burden of cervical cancer and OSCC in Karnataka.     

Prevalence of Human Papillomavirus Genotypes in Women with Normal and Abnormal Cervical Cytology in Iran

Introduction: HPV infection has a prime etiologic role in development and progression of cervical cancer, one ofthe most frequent forms of cancer among women in developing countries. This study was designed to determine themost prevalent HPV genotypes in women with normal and abnormal cervical cytology in Iran. Materials and Methods:Samples from134 patients, including 127 who attended gynecology clinics and 7 with solid cervical tumors wereused. All 127 patients underwent routine Pap tests for cytological evaluation and at the same visit a sample ofcervical epithelial cells was obtained by scraping the cervix osteum. In each case HPV infection was primarily evaluatedby PCR using GP 5/6 primers and then subtyping was performed in proved infected samples with specific primersfor HPV 16, 18, 31, 33, 11 and 6. After cytological evaluation, 50 patients with abnormal Pap tests were categorizedas the abnormal group and the remaining 77 patients as the normal group. Results: In the normal group, HPVinfection was established in 10 cases (13% infection rate), while 30 HPV positive cases were discovered in the abnormalgroup (60% infected). The most prevalent genotypes among the infected samples were HPV 16 (76%), HPV18 (12.7%)and HPV11/6 (8.5%). Moreover, all 7 tumor samples were positive for HPV general primers of which, 5 sampleswere infected with HPV 16, two were co-infected with HPV16,18 and HPV16,31 genotypes and one was infected withHPV 18. Conclusions: Infection with HPV 16 was found to be significantly higher in abnormal group in comparisonwith normal group (42% vs. 11.6%, P value <0.005), likewise HPV18 genotypes were proved to be more prevalent inabnormal group (8% vs. 0%, P value <0.05). No significant relation between other HPV genotypes and pathologiccervical changes was obtained. According to our study high rates of infection with HPV genotypes in sexually activeIranian women makes molecular investigation for HPV16 and 18 very essential in clinical approaches to patientswith proven dysplasia in their screening tests and also for those patients with borderline (i.e. ASCUS) or incongruouspathology reports. Larger studies are required to determine the most appropriate vaccine with highest protection inIranian women.

Prevalence of human papillomavirus (HPV) infection in Basque Country women using slot-blot hybridization: a survey of women at low risk of developing cervical cancer.

Cervical smears from 1,178 women with cytologically normal cervices and 67 women with cervical intra-epithelial neoplasia (CIN) or cervical carcinoma were analyzed for the presence of HPV 6, 11, 16 and 18 DNA by slot-blot hybridization. HPV DNA was detected in 17% (95% CI: 14%-19%) of the women with a normal smear; 11% of infected women harboured HPV 16 and 18 (95% CI: 9%-13%, each). HPV DNA was detected in 54% (95% CI: 41%-66%) of patients with abnormal smear; the most prevalent virus type in this group was HPV 16 (45%; 95% CI: 32%-38%). In order to verify the slot-blot results, a proportion of the samples was also investigated by PCR. There was 88% correlation between the 2 tests. The high prevalence of HPV 16 and 18 infection demonstrated in our low-cervical-cancer-risk area further support the role of as yet unidentified co-factors as determinants of the different geographic rates of cervical-cancer incidence.

Different human papillomavirus 16/18 infection in Chinese non-small cell lung cancer patients living in Wuhan, China

BACKGROUND: Inconsistency in the prevalence of infection by human papillomavirus (HPV) in lung cancer patients was found between different countries with racial and geographic variations. Our previous reports have indicated that a high-risk HPV 16/18 DNA was frequently detected in Chinese lung cancer patients living in Taichung, Taiwan (Cheng et al. Cancer Res. 2001;61:2799-803). Thus, we conducted this study to verify whether there was a similar HPV 16/18 infection prevalence in lung cancer patients from Wuhan, China. METHODS: To reduce the false positive HPV detection, the paraffin sections of 73 lung tumors and 34 non-cancer controls from Wuhan, China were collected for detection of the presence of HPV 16/18 DNA by in situ hybridization (ISH). RESULTS: Our results showed that the rates of HPV 16 and/or 18 infections in patients with lung tumors were significantly higher than in 34 non-cancer control subjects (26.0 versus 2.8% for HPV 16, P = 0.030; 23.3 versus 5.7% for HPV 18, P = 0.031; 27.7 versus 5.9% for HPV 16 or 18, P = 0.003) with a similar infection frequency of HPV 16 and 18 types in lung tumors. This result indicated that HPV 16/18 infection may be associated with lung cancer development in Chinese patients from Wuhan, China. Further statistical analyses revealed that HPV 16 or 18 infection was not correlated with any clinico-pathological parameter studied, including age, gender, smoking status, tumor type, tumor stage and tumor grades. Interestingly, smoking and male patients had a higher prevalence of HPV 16, although not reaching a statistical significance, compared with non-smoking and female patients, respectively (33.3% for smokers versus 20.0% non-smokers; 33.3% for male versus 17.6% for female). As compared with the HPV 16/18 infection in Taiwan, Chinese patients with lung cancer from Wuhan had a different HPV 16/18 infection prevalence. CONCLUSION: Difference in HPV 16/18 infection in lung cancer patients from Wuhan, China and Taichung, Taiwan suggests that HPV 16/18 might play a different role in lung cancer development among Chinese living in different areas.

The association of human papillomavirus 16/18 infection with lung cancer among nonsmoking Taiwanese women

Lung cancer is the leading cause of cancer death in Taiwanese women since 1982. High lung cancer mortality ratio of male:female in Taiwan (2:1) was observed, although less than 10% of female lung cancer patients are smokers. Until now, the etiological factor remains unknown. We hypothesize that high-risk human papillomavirus (HPV) 16/18 may be associated with lung cancer development based on high prevalence of p53 negative immunostainings in female lung tumors compared with that of male lung tumors. In this study, 141 lung cancer patients and 60 noncancer control subjects were enrolled to examine whether HPV 16/18 DNA existed in lung tumor and normal tissues by nested PCR and in situ hybridization (ISH), respectively. The concordant detection of HPV 16 and 18 DNA between nested PCR and ISH method was 73 and 85.5%, respectively. Our data showed that 77 (54.6%) of 141 lung tumors had HPV 16/18 DNA compared with 16 (26.7%; P = 0.0005) of 60 noncancer control subjects. In addition, ISH data showed that HPV 16/18 DNA was uniformly located in lung tumor cells, but not in the adjacent nontumor cells. When study subjects were stratified by gender, age, and smoking status, nonsmoking female lung cancer patients who were older than 60 years old had significantly high prevalence of HPV 16/18 infection. The odds ratio of HPV 16/18 infection of nonsmoking female lung cancer patients is much higher at 10.12 (95% confidence interval, 3.88-26.38) compared with 1.98 (95% confidence interval, 0.84-4.76) of nonsmoking male lung cancer patients. This result strongly suggests that HPV infection is associated with lung cancer development of nonsmoking female lung cancer patients. The high prevalence of HPV 16/18 infection may explain to a certain extent why Taiwanese women nonsmokers had a higher lung cancer mortality rate.     

人乳头瘤病毒16、18型在乳腺癌组织中的表达

目的：探讨人乳头瘤病毒（ＨＰＶ）１６、１８型感染与人乳腺癌病因学的关系。方法：采用免疫组化法（ＳＰ）检测ＨＰＶ１６、１８Ｅ６蛋白在１０例正常乳腺组织,４５例乳腺癌组织中的表达并对癌组中１３例ＨＰＶ１６、１８Ｅ６蛋白阳性材料进行ＨＰＶ１６、１８ＤＮＡ原位杂交检测。结果：癌组中ＨＰＶ１６、１８Ｅ６阳性率为５３．３％（２４／４５）,而正常乳腺组织中均为阴性表达。ＨＰＶ１６、１８ＤＮＡ阳性率为３８．５％（
