    Cervical cancer is a common malignancy which poses a significant health burden among women, especially those living in the developing countries. Although human papillomavirus (HPV) infection has been unequivocally implicated in the etiopathogenesis of the cancer, it alone is not adequate to contribute to the malignant transformation of cervical cells. Most HPV infections regress spontaneously, and only a small proportion of women have persistent infections which eventually lead to malignancy. This suggests that interplays between HPV infection and other cofactors certainly exist during the process of cervical carcinogenesis, which synergistically contribute to the differential susceptibility of an individual to the malignancy. Undoubtedly, host genetic factors represent a major element involved in such a synergistic interaction, and accumulating evidence suggests that polymorphisms in apoptosis-related genes play an important role in the genetic susceptibility to cervical cancer. This review consolidates the recent literatures on the role of common polymorphisms in apoptosis-related genes in genetic susceptibility to cervical cancer.

    The present study was undertaken to evaluate the prevalence of HPV in formalin-fixed, paraffin-embedded cervical carcinoma tissues using PCR followed by non-radioactive Southern hybridization with type-specific oligonucleotides for HPV 16 and 18. In addition, the tissue sections were immunohistochemically screened with two monoclonal antibodies, for expression of HPV 16 L1 and HPV 18 E6 proteins. A total of 57 of 60 cervical carcinomas (95.0%) were found with HPV using both techniques. HPV 16 and HPV 18 were present in equal proportions. Results of both DNA hybridization and immunohistochemistry were in agreement for the majority of the cases. HPV 16 and 18 DNA and virus-encoded antigens, L1 and E6 were found highly prevalent in these cervical carcinomas. Due to the high prevalence of HPV with cervical carcinoma in Malaysia, the implementation of routine diagnosis for the virus in cervical biopsies would be clinically useful.

    Specific human papillomavirus (HPV) types have been implicated in the development of cervical carcinoma worldwide. Novel molecular techniques have facilitated the detection and typing of HPV in cervical lesions. DNA preparations from a series of 23 histopathologically confirmed cervical carcinoma patients were analyzed by polymerase chain reaction (PCR) using degenerate primers for the presence of HPV DNA sequences. A total of 22 of 23 cases studied (95.7%) were found positive for HPV DNA sequences. Further studies by DNA hybridization with viral specific probe and restriction enzyme analysis demonstrated the presence of HPV 16 in 73.9% (17/23) and HPV 18 in 65.2% (15/23) of the cases examined. Interestingly, the uncommon HPV 31 and 33 were also found but with a lower percentage (16.9%). It was noted that HPV 16 frequency in the carcinoma increased with age but HPV 18 was evenly present at all ages investigated. We found that HPV was frequently associated with the majority of the cervical carcinomas, and in all but one case, oncogenic high risk HPV genotypes were present. We conclude that HPV infection of the genital tract has an important role in the development of the disease in Malaysia.

    Human papilloma virus (HPV) affects predominantly the genital area, which includes vagina, cervix, penis, vulva scrotum, rectum and anus. Among 100 types of HPV, 14 types are considered to cause the risky cancer. The gene HPV-16 E7 is responsible for the development of cancer with the infected women. Earlier identification of this gene sequence avoids the cancer progression. The targeted HPV-16 E7 sequence was sandwiched by capture and reporter sequences on the carbodiimidazole-modified interdigitated electrode (IDE) surface. Target sequence at 100 f. was paired to the capture sequence immobilized on IDE sensing surface. To this surface, different concentrations of reporter sequence with and without gold rod (GNR) were evaluated. In both cases the detections were attained 1 aM by the reporter sequence pairing and with GNR increments in current were found. This enhancement was found to be 1000 folds, considering the condition was revealed in the absence of reporter. This sandwich detection strategy of capture-target-reporter sequences for HPV-16 detection on the IDE sensing surface helps to diagnose the association of cervical cancer.

    Since licensing in 2006, there has been poor uptake of the HPV vaccine among the targeted population in the South East Asia Region (SEAR) and Western Pacific Region (WPR). A systematic review was conducted to identify the studies exploring the relationship between factors and intention for HPV vaccination among women in SEAR and WPR countries. Nineteen studies were identified as suitable for qualitative synthesis, and three as suitable for meta-analysis. Most women had a positive intention to have an HPV vaccine (range 57%-85%). Having a positive intention to vaccinate was significantly higher among women not aware of HPV infection (OR: 1.34, 95% CI: 1.02-1.76) and HPV vaccine (OR: 1.57, 95% CI: 1.26-1.96). Lower knowledge level and less confidence in safety and efficacy of the vaccine, negatively affected intention to vaccinate. Perceiving the vaccine to be expensive, low perception of contracting HPV infection and cervical cancer, and lack of concrete recommendations from healthcare providers also negatively affected intention to vaccinate. This review suggests the decision-making processes of women in SEAR and WPR is influenced by the cost of vaccination, perceived efficacy and safety of vaccine, provision of information on vaccination, and the awareness about HPV infection and the HPV vaccine.

    Cervical cancer is caused by HPV infection and can be prevented by early vaccination.

    OBJECTIVE: To assess Syrian women's level of knowledge and determinants of good knowledge of cervical cancer, HPV infection and its vaccines.

    METHODS: A cross sectional survey was undertaken among mothers with daughters in sixth grade classes enrolled in primary schools in Aleppo city, Syria. Samples were selected through cluster sampling and data collected using a self-administered questionnaire.

    RESULTS: Less than a third of the mothers had heard of HPV infection and vaccines against cervical cancer and levels of knowledge were generally low. Good knowledge was associated with high education level, higher family monthly income, having few--less than four children, positive history of cervical cancer screening, and working or having relatives working in the medical field. The main source of information was television and few reported health care providers as a source of knowledge on HPV infection and vaccine.

    CONCLUSION: Since knowledge of HPV infection and its connection with cervical cancer and its vaccine are low, more efforts must be made to educate Syrians prior to introduction of any HPV vaccination programme. Public health efforts must focus on educating mothers, the public as well as health care providers.

    Cervical cancer is the third most common cancer in women in peninsular Malaysia and very prevalent worldwide. HPV vaccination and routine Pap smear testing are the best preventive measures. The objective of this study was to determine the knowledge level of secondary school students from Sarawak, East Malaysia regarding cervical cancer and its prevention. Multistage random sampling with various methods in each step was employed to select the sample of 76 students. Results showed that 61.8% had poor knowledge level of cervical cancer and its prevention. There were 60.5% of students who were aware of cervical cancer with Chinese and form four students showing significantly the highest awareness (p<0.05). The main source of cervical cancer information was from their parents (25.9%). HPV vaccination acceptance among students was 22.3% and an association was found between knowledge of cervical cancer with race and HPV vaccination acceptance (p<0.05). In conclusion, the students had poor knowledge level of cervical cancer, its prevention and HPV vaccination acceptance. More efforts should be made to improve cervical cancer knowledge and awareness of the public especially secondary school students in Sarawak. This in turn will enhance the practice of prevention against cervical cancer among students.

    A cross-sectional study was conducted among 300 Malaysian women in the obstetrics and gynecology outpatient clinic in a selected hospital in Bangi, Selangor to determine the level of knowledge of HPV and HPV vaccines, attitudes toward HPV vaccination and barriers of being vaccinated. Factors associated with knowledge and attitudes were also addressed with a questionnaire. Seventy eight women (26%) had heard about the HPV virus and 65 about HPV vaccines (21.7%). Marital status was associated significantly with awareness of HPV and HPV vaccine (p=0.002, p=0.002; respectively), in addition to level of education (p=0.042). The percentages of women who reported correct answers for the questions on knowledge of HPV and HPV vaccine ranged from 12% to 25%. One hundred fifty nine respondents (53%) had a positive attitude toward HPV vaccination. Age, marital status, and level of education were associated significantly with attitude (p<0.001, p<0.001, p=0.002; respectively). The most important barriers reported were 'unawareness of the vaccine' 'concerned about side effects' and 'afraid of needles'. This study found a very low level of knowledge of HPV and HPV vaccine. Education of population is highly recommended and barriers to being vaccinated should be dealt with seriously.

    Association of High-risk Human Papillomavirus (HR-HPV) with oral cancer has been established recently. Detecting these viruses in oral cavity is important to prevent oral lesions related to them. The purpose of this study was to evaluate the prevalence of HR-HPV in the oral cavity of women with cervical cancer, and their children. A total of 70 women, previously diagnosed with cervical cancer, and 46 children of these women, born by vaginal delivery only, were selected for this study. Buccal swabs were collected from their oral cavity and HPV detection was carried out using Hybrid Capture 2 high-risk HPV (HC2 HR-HPV) detection system.

    To determine why HPV vaccination uptake is low in Asia, we surveyed attitudes, knowledge and communication about cervical cancer and HPV vaccination amongst 480 physicians and 1617 randomly selected urban mothers who could afford HPV vaccines in Korea, Malaysia, Taiwan and Thailand. HPV vaccine rejection by mothers was linked with poor knowledge and low perceptions of self-relevance. Physicians' likelihood of raising the subject and/or recommending vaccination was linked to how proactively they advocate preventive health, their attitude to the subject's sensitivity and their knowledge levels. Because most Asian mothers seek doctors' advice and prefer them to take the initiative, physicians should be more proactive in discussing and recommending HPV vaccination.

    Cervical cancer is the second most common female malignancy in Malaysia. Despite advances in treatment, the overall survival for this disease has not changed in the last decade. Infection by certain types of HPV is recognized as a causal and necessary factor for its development. This study was carried out to determine the prevalence of HPV infection in abnormal cervical smears in Malaysian patients using archival cervical smears retrieved from the Cytopathology Unit, Universiti Kebangsaan Malaysia Medical Centre (UKMMC) between the years 1992-1995. DNA was extracted from 38 abnormal smears comprising 25 intraepithelial lesions and 13 cervical carcinomas and 10 normal smears. Amplification of HPV genes was carried out using the polymerase chain reaction (PCR) technique. HPV genotypes were determined using direct sequencing and the results were compared to the database from Genebank. DNA was successfully extracted from all 48 cervical smears. High-risk HPV (HR-HPV) genotypes were detected in 95% of the abnormal smears. Eight high-risk oncogenic types were identified: 16, 18, 31, 51, 52, 56, 58 and 66. All (100%) cervical cancer smears showed presence of HR-HPV compared to 92% of the cervical intraepithelial lesions. Among the eight HR-HPV genotypes identified, HPV 16 and 52 were the commonest (23.7% each) HPV genotypes encountered and among the CIN lesions, HPV 16 (28%) was the most frequent. We conclude that HPV 16 is the most prevalent HPV genotype present in abnormal cervical smears in Malaysian patients, and that the use of archival material to assess the presence of HPV is potentially worthwhile, and can be utilized for longitudinal studies of HPV presence and persistence.

    In order to investigate the reliability of detecting HPV DNA in cervical smears, we compared the performance of nested MY/GP PCR and FDA approved-Hybrid Capture II (HCII) using clinical cervical scrapings from 40 patients. It was found that PCR was more sensitive (81.8%) in comparison to HCII (36.4%) in detecting HPV although specificity of HCII was much higher (96.6%) than PCR (58.6%). The Negative Predictive Value (NPV) of both the techniques were quite similar but Positive Predictive Value (PPV) of HCII was much higher (80.0%) compared to PCR (42.9%). While the HCII method showed good specificity for HPV detection, its lack of sensitivity as compared to PCR may be a drawback for diagnostic use.

    Cervical carcinoma, the second most common malignancy in Malaysian females, is aetiologically linked to the human papillomavirus (HPV). A study was conducted at the Department of Pathology, University of Malaya Medical Centre to compare the identification of HPV 6, 11, 16 and 18 in 40 archived formalin-fixed, paraffin-embedded cervical carcinoma by non-isotopic in-situ hybridisation (NISH) and polymerase chain reaction (PCR). HPV L1 ORF consensus PCR was also carried in cases which were negative on HPV type-specific PCR. NISH detected HPV 16 in 13 (32.5%) cases with one case demonstrating a concomitant HPV 18. beta-globin DNA PCR was carried out on the same paraffin block as for NISH in 27 cases and on a different paraffin block in 13, with amplification in 9 of the former and 3 of the latter. Thus only 12 cases were subjected to further HPV PCR. HPV was detected in 10 (83.3%) with HPV 16 in 9 cases and HPV L1 ORF in one. When using the same paraffin block for both methods of HPV detection, NISH detected HPV in 6 and PCR in 7. NISH failed to detect HPV in a case detected by PCR. 2 cases were negative for HPV using both methods. Hence, HPV detection results by NISH and PCR were concordant in 88.9%. Interestingly, NISH detected HPV in 2 cases with non-amplifiable beta-globin DNA. Using an alternative paraffin block for HPV PCR from NISH, HPV DNA was detected in 3 cases, two of which also showed type-specific positivity on NISH. The third case did not reveal type-specific positivity with NISH or PCR but demonstrated HPV DNA on L1 ORF consensus PCR. It thus appears that PCR and NISH can be successfully used to detect HPV in formalin-fixed, paraffin-embedded tissue and in the presence of intact DNA NISH may be as sensitive as PCR.

    BACKGROUND: Cervical cancer is the fourth most common cancer among women worldwide. Studies evaluating the effect of health education on knowledge and perception of cervical cancer have generated conflicting results. Thus, this study aimed to evaluate the effect of educational intervention towards knowledge of HPV vacccination for cervical cancer prevention among pre-university students in Malaysia.

    MATERIALS AND METHODS: This was an experimental before and after study performed between October 2014 and March 2015. Five hundred and eighty students were randomly assigned into intervention and control groups. All were required to complete both pre-intervention and post-intervention questionnaires. Those in the intervention group were given an information leaflet to read before answering the post-intervention questionnaire.

    RESULTS: Almost half (48.3%) of the students had poor knowledge, with a score less than 5, and only 51 (8.8%) exhibited good knowledge, with a score of 11 and above. After educational intervention, the number of students with poor knowledge was reduced to 177 (29.3%) and the number of students who exhibited good knowledge increased to 148 (25.5%). Students from the intervention group demonstrated significant higher total scores in knowledge regarding 'HPV infection and cervical cancer' (p=0.000) and 'HPV vaccination and cervical cancer prevention' (p=0.000) during post-intervention as compared to the control group.

    CONCLUSIONS: Knowledge on HPV infection and vaccination is low among pre-university students. Educational intervention in the form of information leaflets appears effective in creating awareness and improving knowledge.

    Historical cottontail rabbit papillomavirus studies raised early indications of a mammalian DNA oncogenic virus. Today, molecular cloning recognises numerous animal and human papillomaviruses (HPVs) and the development of in vitro transformation assays has escalated oncological research in HPVs. Currently, their detection and typing in tissues is usually by Southern blotting, in-situ hybridization and polymerase chain reaction methods. The complete papillomavirus virion constitutes a protein coat (capsid) surrounding a circular, double-stranded DNA organised into coding and non-coding regions. 8 early (E1-E8) open reading frames (ORFs) and 2 late (L1, L2) ORFs have been identified in the coding region of all papillomaviruses. The early ORFs encode proteins which interact with the host genome to produce new viral DNA while late ORFs are activated only after viral DNA replication and encode for viral capsid proteins. All papillomaviruses are obligatory intranuclear organisms with specific tropism for keratinocytes. Three possible courses of events can follow papillomaviruses entry into cells: (1) viral DNA are maintained as intranuclear, extrachromosomal, circular DNA episomes, which replicates synchronously with the host cell, establishing a latent infection; (2) conversion from latent into productive infection with assembly of complete infective virions; (3) integration of viral DNA into host cellular genome, a phenomenon seen in HPV infections associated with malignant transformation. Human papillomaviruses (HPVs) essentially induce skin and mucosal epithelial lesions. Various skin warts are well known to be HPV-associated (HPVs 1, 2, 3, 7 and 10). Besides HPVs 3 and 10, HPVs 5, 8, 17 and 20 have been recovered from Epidermodysplasia verruciformis lesions. Anogenital condyloma acuminatum, strongly linked with HPVs 6 and 11 are probably sexually transmitted. The same HPVs, demonstrable in recurrent juvenile laryngeal papillomas, are probably transmitted by passage through an infected birth canal. HPVs described in uterine cervical lesions are generally categorized into those associated with high (16, 18), intermediate (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) and low (6, 11, 26, 40, 42, 43, 44, 53, 54, 55, 62, 66) risk of cervical squamous carcinoma. Cervical adenocarcinoma, clear cell carcinoma and small cell neuroendocrine carcinoma have also been linked to HPVs, especially HPV18. Other lesions reported to be HPV-associated are: papillomas, dysplasia and carcinomas in the nasal cavity (HPV 6, 11, 57); squamous papilloma, condyloma acuminatum, and verruca vulgaris of the oral cavity (HPV 6, 11), oral focal epithelial hyperplasia (HPV 13, 32); warty lip lesions (HPV 2): and conjunctival papillomas (HPV 6, 11).

    BACKGROUND: Human herpesvirus type 6 (HHV-6), an ubiquitous virus, is the causative agent for exanthem subitum. The virus is frequently associated with lymphoproliferative disorders and other diseases. Recently, we have reported the frequent presence of HHV-6 in oral carcinoma and the present study extends the observation to cervical carcinoma.

    OBJECTIVE: To examine the presence of HHV-6 in cervical carcinoma.

    STUDY DESIGN: Formalin-fixed, paraffin-embedded cervical carcinoma tissues were examined for the presence of HHV-6 by immunohistochemistry using two monoclonal antibodies that react to HHV-6-encoded p41/38 and gp116/64/54. In situ hybridization with variant-specific probes were used to type the HHV-6 DNA sequences present.

    RESULTS: A total of 14/26 (53.9%) carcinoma tissue specimens and 5/8 (62.5%) normal tissue specimens were positive for viral antigens. In situ hybridization studies revealed the presence of HHV-6 DNA sequences in 10/26 (38.5%) carcinoma tissue specimens and 1/8 (12.5%) normal tissue specimens. In the normal tissue, the HHV-6 was present in the endocervical ciliated columnar-epithelial cells and some cells in the subepithelial mucosa but in the carcinoma, the transformed cells were positive for the virus.

    CONCLUSIONS: HHV-6 viral proteins and DNA were found in more than one third of the cervical tissue examined suggesting possible viral expression in these tumours. The significance of the distribution and role of the HHV-6 in cervical tissue remains unclear. Since HHV-6 has an oncogenic potential, the virus may cooperate with other transforming agents for the progression of the disease.

    Human papillomavirus (HPV) is a double-standard DNA virus, as well as the source of infection to the mucous membrane. It is a sexually transmitted disease that brings the changes in the cervix cells. Oncogenes, E6 and E7 play a pivotal role in the HPV infection. Identifying these genes to detect HPV strains, especially a prevalent HPV16 strain, will bring a great impact. Among different sensing strategies for pathogens, the dielectric electrochemical biosensor shows the potential due to its higher sensitivity. In this research, HPV16-E7 DNA sequence was detected on the carbodiimidazole-modified interdigitated electrode (IDE) surface with the detection limit of 1 fM. To enhance the sensitivity, the target sequence was conjugated on gold nanoparticle (GNP) and attained detection to the level of 10 aM. This produced ~100 folds improvement in detecting HPV16-E7 gene and 4 folds increment in the current flow. The stability of HPV16-E7 DNA sequences on GNP was verified by the salt-induced GNP aggregation. The current system has shown the higher specificity by comparing against non-complementary and triple-mismatched DNA sequences of HPV16-E7. This demonstration in detecting HPV16-E7 using dielectric IDE sensing system with a higher sensitivity can be recommended for detecting a wide range of disease-causing DNA-markers.

    Human papillomavirus (HPV) genotype 52 is commonly found in Asian cases of cervical cancer but is rare elsewhere. Analysis of 611 isolates collected worldwide revealed a remarkable geographical distribution, with lineage B predominating in Asia (89.0% vs 0%-5.5%; P(corrected) < .001), whereas lineage A predominated in Africa, the Americas, and Europe. We propose that the name "Asian lineage" be used to denote lineage B, to signify this feature. Preliminary analysis suggested a higher disease risk for lineage B, although ethnogeographical confounders could not be excluded. Further studies are warranted to verify whether the reported high attribution of disease to HPV52 in Asia is due to the high prevalence of lineage B.
