Purpose: This study was conducted to identify the factors influencing of HPV vaccination and vaccination intention among Korean adult women through a systematic review. Methods: A systematic review was conducted across international and domestic electronic databases and nine of 193 studies were identified for this review. Results: Meaningful variables influencing HPV vaccination and its intention included socioeconomic status (age, economic level, and education level), knowledge level, health beliefs, attitudes toward HPV vaccination, and previous experiences. Economic level and knowledge influenced HPV vaccination and vaccination intention, which was consistent with the results of previous studies. Eight studies measured knowledge level regarding cervical cancer or HPV vaccination; however some instruments lacked reliability and validity report. Conclusion: There is a need for governmental support to reduce the burden of HPV vaccination cost, to publicize the benefits and to provide general information regarding HPV vaccination. Finally, it is necessary to develop an instrument with confirmed reliability and validity to measure HPV knowledge.

The genotypes of Human Papilloma Virus (HPV) are important in the carcinogenesis of uterine cervical cancer. Diagnosis of uterine cervical cancer screening has been executed using Papanicolau method (Pap) and HPV DNA Chip method. We researched the interrelation of HPV DNA genotypes in single and multiple infections and analyzed the results of Pap and HPV DNA Chip tests at Gunsan Medical Center (GMC). The correlation analysis was surveyed on collected results from 599 patients who have been tested with both Pap and HPV DNA chip tests from November 2004 to May 2010 at GMC. The inconsistency between Pap and HPV DNA Chip tests was 41.1%. The HPV DNA Chip genotype related with high risk cases were type 16 (13.5%), type 52 (10.5%), type 58 (10.1%), and type 18 (3.4%). Those related with low risk cases were type 70 (8.9%), type 6 (1.7%), type 40 (1.2%), type 11 (1.3%), and other types (14.3%). Among the 195 cases of HPV positive status, 161 cases were associated with single infection; 108 (67.1%) cases were related with high risk genotype; 19 (11.8%) cases were low risk genotype; 31 (21.1%) cases were related with other types. 29 cases were associated with double infections; 23 (79.3%) cases were high risks; 5 (17.2%) cases were mixed high and low risks; 1 (3.5%) case was low risk.

This study focused on infection rates and subtypes of human papillomavirus (HPV) in patients with oropharyngeal squamous cell carcinoma (OSCC), and the relationship between HPV status and prognosis of the disease. We evaluated sixty-six OSCC patients who met the enrollment criteria during the period from January 1999 to December 2009. The presence or absence of oncogenic HPV types in tumors was determined using the SPF10 LiPA25 assay. Overall survival (OS) and disease specific survival (DSS) for HPV positive and HPV negative patients were estimated using Kaplan-Meier analysis. The Cox regression model was applied for multivariate analysis. HPV-DNA was detected in 11(16.7%) of all specimens. Among them, 7 were type HPV-16, while other types were HPV-16/11, HPV-35, HPV-58/52, and HPV-33/52/54. Patients with HPV positive tumors were more likely to be female, non-smokers and non-drinkers (p=0.002, 0.001 and 0.001, respectively). After a median follow-up of 24.5 months, patients with HPV positive tumors had significantly better overall survival (HR=0.106[95%CI=0.014-0.787], p=0.016,) and disease specific survival (HR=0.121[95%CI=0.016-0.906], p=0.030). Patients with HPV positive OSCC have significantly better prognosis than patients with HPV negative tumors. HPV infection is an independent prognostic factor.

Background: Human papillomavirus (HPV) infection is the main cause of cervical cancer. Limited epidemiologic data of HPV prevalence are available for women attending hospitals in southern China. This study aimed to evaluate the profiles of HPV infection and cytology status in gynecological outpatients in Chaozhou City. Methods: A total of 2833 eligible women were enrolled. The HPV GenoArray test was used for HPV detection and genotyping. Nearly one half of the HPV positive women received liquid-based cytology test. Logistic regression analysis was performed to assess the predictable effects of age and genotype for categories of abnormal cytology. Results: The prevalence of overall, high-risk, and low-risk HPV infection were 24.5%, 19.5% and 8.4%, respectively. A U-shaped age-specific prevalence curve was observed in overall HPV and high-risk HPV, but not in low-risk HPV, which declined with age increasing. The 6 most common high-risk HPV type in descending order, were types 52, 16, 58, 18, 68, and 33. Age and HPV genotype were both important determinants of abnormal cytology incidence, the older women (>45 years) and those infected with HPV type 16 and/or 18 having the highest risk for abnormal cytology. Conclusion: Our findings support the hypothesis that second-generation HPV prophylactic vaccines including HPV-52 and -58 may offer higher protection for women residing in Chaozhou and neighboring cities in Guangdong.

Background: Currently it is believed that human papillomaviruses (HPV) are associated with the development of some oral/oropharyngeal cancers. It has been suggested that these viruses influence carcinogenesis in both smokers and non-smokers. Data on the prevalence of HPV in healthy adults are thus needed to estimate the risk of oral/oropharyngeal cancer. The aim of this study was to assess the prevalence of oral HPV in healthy female adults in Indonesia and Thailand. Materials and Methods: Healthy female students from the Faculties of Dentistry of Universitas Indonesia and Chiang Mai University were asked to participate in this pilot study. DNA was extracted from saliva specimens and screened for HPV16 and HPV18 using PCR. Results: The age, marital status and sexual experience of the subjects between the two countries were not significantly different. Eight (4%) and 4 (2%) samples were positive for HPV16 and HPV18, respectively. Fisher's Exact test found a significant difference between HPV16 positivity in subjects who were married and had sexual intercourse but not for HPV18. Conclusions: This study successfully detected presence of HPV16 and HPV18 DNA in a number of saliva samples from female dental school students. Marital status, experience of sexual intercourse and safe sexual practice are related to the possibility of finding HPV DNA finding in saliva. Dentists, physicians and other health care professionals may gain significant value from the findings of this study, which provide an understanding of the nature of HPV infection and its risk to patient health and disease.

Background: Limited human papillomavirus (HPV) related knowledge might be a barrier to future vaccine acceptance. From 2008-2010, PATH conducted an HPV vaccination demonstration project in partnership with the government immunization program in Vietnam, which included awareness campaigns prior to vaccination. Objective: To assess and compare knowledge and attitudes about cervical cancer and HPV vaccines between mothers and daughters, and whether knowledge was associated with vaccination status. Methods: We analyzed HPV-related knowledge and attitude data from mother-daughter paired responses to a cross-sectional household survey. After parents completed the survey, daughters were asked the same questions. We calculated the frequency of responses for each question and devised a scaled composite measure for knowledge. Results: Participants believed they had received enough information about cervical cancer and HPV vaccines and it was sufficient to make a decision about vaccination. Fifty percent of the participants knew HPV causes cervical cancer and 80% knew the HPV vaccine prevented cervical cancer. Mothers had more knowledge about cervical cancer and HPV infection (p<0.01), compared to daughters, who had more vaccine specific knowledge (p<0.01). However, the total mean knowledge score was similar for the groups. Girls not fully vaccinated had a lower mean knowledge score than fully vaccinated girls (p<0.001). Conclusions: Our results suggest that the purpose of the HPV vaccine was clearly messaged; however, some misconceptions about cervical cancer and HPV still exist. Limited knowledge about the magnitude of cervical cancer, HPV as a cause of cervical cancer, and HPV vaccines may have contributed to incomplete vaccination.

Background: To investigate the infection status and predominant genotype distribution of human papillomavirus (HPV) infection among Chinese patients with mucopurulent cervicitis (MPC) or cervical cancer (CC) in Hangzhou. Methods: Initially, 217 cases of healthy cervix controls (n=50), acute MPC (n=89), and CC (n=78) were included; samples were collected between January 1, 2010, and January 30, 2013. Cervical specimens were screened for HPV using a nested polymerase chain reaction assay and DNA sequencing. Results: Overall prevalence of HPV infection was 16.7% in the control group, 51.9% in the MPC group, and 84.4% in the CC group. The predominant genotype detected in all 3 groups was the oncogenic variant HPV 16 (55.8%, 17.3%, and 6.3% in the CC, MPC and control specimens, respectively), HPV58 was the second most predominant HPV type in CC (9.1%), MPC (8.6%), and control group (4.2%). Most or all of the genotypes were oncogenic in the three groups. Conclusions: Infection with HPV was found to be prevalent among Chinese women with MPC or CC and oncogenic variants were in the majority. Therefore, peoples who suffered MPC with HPV DNA positive should be regularly followed-up, for prevention and early treatment of cervical cancer.

Cervical cancer is one of the most common cancers in women worldwide. During their life time the vast majority of women become infected with human papillomavirus (HPV), but interestingly only a small portion develop cervical cancer and in the remainder infection regresses to a normal healthy state. Beyond HPV status, associated molecular characterization of disease has to be established. However, initial work suggests the existence of several different molecular classes, based on the biological features of differentially expressed genes in each subtype. This suggests that additional risk factors play an important role in the outcome of infection. Host genomic factors play an important role in the outcome of such complex or multifactor diseases such as cervical cancer and are also known to regulate the rate of disease progression. The aim of this review was to compile advances in the field of host genomics of HPV positive and negative cervical cancer and their association with clinical response.

Background: The aim of this study was to screen for human papillomavirus (HPV) infections in head and neck squamous cell carcinomas (HNSCCs) using P16 immunostaining. Materials and Methods: A retrospective study was performed on 150 samples from patients diagnosed with HNSCCs. HPV status was determined using $p16^{INK4A}$. Results: 31 of the 150 (20.7%) HNSCCs were HPV positive. Conclusions: A large proportion of HNSCCs in Sudan are associated with HPV infection. The fact that the prevalence of HPV is high among Sudanese patients with head and neck cancers (HNC) has obvious implications for vaccine therapy.
