Lack of knowledge regarding HPV and its relation to oropharyngeal cancer among medical students

Knowledge and attitude among Egyptian medical students regarding the role of human papillomavirus vaccine in prevention of oropharyngeal cancer: a questionnaire-based observational study

Squamous cell carcinomas in several anatomical sites are caused by human papillomaviruses (HPV), and oncogenic double-stranded DNA viruses. There are about 200 genotypes; HPV16 is the most often occurring variant. Potential ways of infection are skin warts, sexual activity, exposure, immunization, or oral sex. The growing incidence of OPSCC in Western countries makes vaccination increasingly vital. The FDA has approved the 9-valent vaccination as an OPSCC prophylactic agent. Still, political will, inadequate financing, and inadequate infrastructure help to explain the slow dissemination of anti-HPV vaccination. This study sought to evaluate Egyptian medical students' knowledge, awareness, and attitude toward the advantages of HPV vaccination to prevent HPV-associated OPC. The study was a cross-sectional questionnaire-based study consisting of 696 participants from the first to fifth-year students enrolled in any Egyptian medical school registered in the academic year 2023-2024, specifically from June to August 2024, except non-medical, graduate, and non-Egyptian students who met the exclusion criteria. We privately gathered answers via colleagues and electronically via online Google forms posted on social media groups. This study concentrated on the poor knowledge of HPV among Egyptian medical students, particularly urban male students with a mean age of 21.72 ± 1.6 enrolled in clinical years mostly in Cairo, Sharqia, and Gharbia governorates. There was a clear fair attitude regarding the HPV vaccination, especially among urban male students with a mean age of 21.64 ± 1.65 enrolled in clinical years mostly in Cairo, Sharqia, and Alex governorates. Notably, only 7.7% of the students enrolled in the study knew the link between HPV and OPC. However, only 28.5% of participants have received the vaccine. The students said that lack of awareness (82.4%) was the most important obstacle to vaccination; followed by cultural attitudes (44.5%), vaccine accessibility (42.7%), and vaccine cost (41.3%). Ultimately, it was found that Egyptian medical students-especially those enrolled in clinical years in the governorates of Cairo, Sharqia, and Gharbia-have a low degree of knowledge of HPV-related oropharyngeal cancer and its vaccination role. Although preclinical students' knowledge had greatly improved, the limited awareness-especially among clinical students-was concerning.

Medical students' knowledge about human papillomavirus (HPV), HPV vaccine and head and neck cancer

The Human Papillomavirus (HPV) is a sexually transmitted infection that significantly affects the population worldwide. HPV preventive methods include vaccination, prophylactics, and education. Different types of cancers associated with HPV usually take years or decades to develop after infections, such as Head and Neck Cancer(HNC). Therefore, HPV prevention can be considered cancer prevention. A sample of medical students in Puerto Rico was evaluated to assess their knowledge about HPV, HPV vaccine, and HNC through two previously validated online questionnaires composed of 38 dichotomized questions, we measured HPV, HPV vaccination(HPVK), and HNC knowledge (HNCK). Out of 104 students surveyed, the mean HPVK score obtained was 20.07/26, SD = 3.86, while the mean score for HNCK was 6.37/12, SD = 1.78. Bidirectional stepwise regression showed study year and HPV Vaccine name had been the most influential variables on HPVK and HNCK. MS1 participants scored lower than MS2-MS4 participants, with no significant difference between MS2-MS4 scores. The results reveal knowledge gaps in HPV/HPV Vaccine and HNC among surveyed medical students. Our findings also suggest an association between knowledge of personal vaccination status, self-perceived risk, and how uncertainty in these factors may affect the medical students' understanding of HPV, HPV vaccination, and associated cancers.

Awareness and acceptance of human papillomavirus vaccine in the Middle East: A systematic review, meta-analysis, and meta-regression of 159 studies

Cervical cancer, closely linked to human papillomavirus (HPV) infection, is a major global health concern. Our study aims to fill the gap in understanding HPV vaccine awareness and acceptance in the Middle East, where national immunization programs are often lacking and cultural perceptions hinder acceptance. This systematic review and meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive literature search across several databases was conducted on 5 September 2023. We included quantitative studies on HPV vaccine awareness and acceptance in Middle Eastern countries. Data extraction and quality assessment were conducted independently by multiple reviewers to ensure accuracy. Statistical analyses, including subgroup analyses, were performed using R to calculate pooled estimates, assess heterogeneity, and publication bias. We reviewed 159 articles from 15 Middle Eastern countries, focusing on 93,730 participants, predominantly female and healthcare workers. HPV vaccine awareness was found to be 41.7% (95% CI 37.4%-46.1%), with higher awareness among healthcare workers. The pooled acceptance rate was 45.6% (95% CI 41.3%-50.1%), with similar rates between healthcare and non-healthcare workers. Our study highlights the critical need for increased HPV vaccine awareness and acceptance in the Middle East, emphasizing the importance of integrating the vaccine into national immunization programs and addressing cultural and religious factors to improve public health outcomes.

Awareness of the Link Between Human Papilloma Virus Infection and Head and Neck Cancer Among the General Population and Practitioners: A Literature Review

Background: Human papilloma virus (HPV) infection is responsible for 4.5% of cancers worldwide, i.e., for around 630,000 new cases per year. Around 38,000 cases per year of HPV-related cancers arise in the head and neck region, of which 21,000 cases are oropharyngeal squamous cell carcinomas (OPSCCs), with an increasing frequency in high-income countries. In our work, we aimed to collect the available evidence about the awareness of the relation between HPV infection and head and neck cancer among patients and practitioners. Methods: This review was based on all available prospective and retrospective studies, case reports, and review articles published up to May 2024 in PubMed. The search keywords used included "human papilloma virus" plus "head and neck cancer", "awareness", "infection", "vaccination", "awareness in patients and practitioners", "oropharyngeal squamous cell carcinoma", "HPV16-18", "HPV awareness", "cervical cancer". Results: In the U.S.A., with more than 150.00 participants interviewed through different studies, the identification of HPV infection as a risk factor for head and neck cancer (HNC) was made by only 12-39% of the participants. Similar conclusions were drawn from European studies in which only 10-52% of the participants recognized HPV as a risk factor for HNC. HPV-related HNC awareness in health care providers and medical/dental students showed a high variability among studies, being otolaryngology and dental sciences specialists the most conscious in comparison to general practitioners, who demonstrated a low level of awareness. Conclusions: There is a dangerous lack of awareness about HPV infection and its potential role in HNC among both general populations and health care practitioners. A great effort should be made to increase awareness in both practitioners and the general population on this topic, also aiming to increase the HPV vaccination coverage.

Willingness to get HPV vaccination among female university students in Kuwait and its relation to vaccine conspiracy beliefs

A substantial burden of high-risk human papillomavirus (HPV) infections and HPV-related cancers can be mitigated by vaccination. The current study aimed to investigate the willingness of female students at the University of Kuwait to get HPV vaccination and its possible association with general vaccine conspiracy beliefs (VCBs). This cross-sectional survey study was conducted during September-November 2022 using a validated VCB scale as the survey instrument. The final sample comprised 611 respondents with a median age of 22 y and a majority of Arab ethnicity (n = 600, 98.2%). Only 360 respondents (56.9%) heard of HPV before participation and these students showed an above-average level of HPV knowledge (mean knowledge score of 12.7 ± 2.6 out of 16 as the maximum score), of whom only 33 self-reported HPV vaccine uptake (9.2%). The willingness to accept free-of-charge HPV vaccination was seen among 69.8% of the participants, with 20.1% who were hesitant and 10.1% who were resistant. The acceptance of HPV vaccination if payment is required was 23.1%. Reasons for HPV vaccine hesitancy/resistance included complacency to the HPV disease risks, lack of confidence in HPV vaccination, and inconvenience. The embrace of VCBs was associated with significantly higher odds of HPV vaccine hesitancy/resistance. The current study showed the detrimental impact of endorsing vaccine conspiracy beliefs manifested in lower intention to get HPV vaccination among female university students in Kuwait. This should be considered in vaccine promotion efforts aiming to reduce the burden of HPV cancers.

Awareness and knowledge of physicians and residents on the non-sexual routes of human papilloma virus (HPV) infection and their perspectives on anti-HPV vaccination in Jordan

BACKGROUND AND OBJECTIVES

Although penetrative sex is the most common route of HPV infection, there is strong evidence of non-sexual modes of transmission. As the first of its kind, this study aimed to investigate the knowledge and awareness of Jordanian physicians on such routes.

METHODS

A questionnaire was conducted among a national Jordanian sample of physicians from Jordanian health sectors. The survey included questions assessing participants' knowledge on HPV, non-sexual routes of infection and HPV vaccines. Physicians' attitudes towards HPV screening and vaccination were covered. Statistical analysis was carried out using SAS 9.4, ANOVA, post-hoc Tukey-Honest test and Kruskal-Wallis test. All significant differences were set at α = 0.05.

RESULTS

A total of 412 participants completed the survey. Physicians showed a huge deficit in knowledge on nonsexual routes of HPV transmission. They agreed that the most and least common routes of non-sexual transmission are skin to mucosa (64%) and contaminated water (15%), respectively. Females showed significantly better knowledge in all aspects of HPV transmission and vaccination (p<0.0001) and more positive attitudes towards HPV screening and vaccination compared to males (p = 0.03). Age group ≤ 25 and academic physicians demonstrated higher knowledge on HPV vaccines compared to their counterparts in non-academic places (p = 0.002). Specialty and experience seemed to have no impact on knowledge or attitudes of participants. Higher knowledge physicians had more positive attitude towards vaccination and screening compared to lower knowledge fellows (p<0.001).

CONCLUSIONS

The noteworthy findings of this study is the extremely low level of knowledge on non-sexual routes of HPV infection among Jordanian physicians. Increasing the level of awareness of physicians and healthcare workers on these routes and their association with cervical and other cancers through university curricula and other reliable sources is strongly recommended.

Evaluation of the Knowledge of the Most Common Cancers Among Health Students at Jazan University, Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Cancer is a major public health problem worldwide, and medical students are expected to have adequate knowledge and awareness of the most common types of cancer. This study aimed to assess the cancer knowledge of medical students at Jazan University, Saudi Arabia, focusing on breast cancer (BC), prostate cancer (PC), cervical cancer (CC), and colorectal cancer (CRC).

METHODS

This study employed a self-administered survey to evaluate both general and specialized knowledge of cancer types. A total of 321 medical students from different academic years participated in the study. The questionnaire used a scoring system where each correct answer was given one point, and each incorrect answer or "I don't know" response was given zero points.

RESULTS

The overall knowledge scores were 18.75 ± 4.43 out of 28 (67%). The students had a good level of general knowledge about cancer (5.26 ± 1.44 out of 7, 75%) and breast cancer (5.47 ± 1.44 out of 7, 78%) and a moderate knowledge level of prostate cancer (2.83 ± 1.07 out of 4, 71%), cervical cancer (2.74 ± 1.53 out of 5, 55%), and colorectal cancer (2.55 ± 1.61 out of 5, 50%). There were significant differences in cancer knowledge by gender, academic year, and having a relative or friend with cancer. All types of cancer knowledge were positively and significantly correlated with each other.

CONCLUSION

This study revealed the strengths and weaknesses of cancer knowledge among medical students at Jazan University, Saudi Arabia. The overall score for knowledge indicated a moderate level. The students had some knowledge about cancer prevention, detection, and treatment, but some gaps and misconceptions need to be addressed. More education and awareness programs are necessary to improve cancer literacy among students and promote healthy behaviors that can reduce cancer risk.

Identification Level of Awareness and Knowledge of Emirati Men about HPV

One of the most frequent cancers that affects males globally is cervical cancer (CC) that kills hundreds or even thousands of women each year, particularly in underdeveloped nations. The study focuses on human papillomavirus (HPV) that contributes to cervical cancer (CC) development. In the majority of Arab nations, there seems to be no public education or vaccination programs. In research, methodological rigor is employed to find solutions to both theoretical and practical difficulties. This research aims to assess the knowledge and awareness of the HPV vaccination among Emirati men. Results of the research showed that Emirati males had a poor understanding of HPV and its vaccination. According to the findings of this research, Emirati males lack a basic understanding of HPV, which necessitates the implementation of national HPV education initiatives. We have identified several critical knowledge gaps that can be filled in the future regarding HPV infection and vaccination.

HIV Knowledge and Stigmatizing Attitude towards People Living with HIV/AIDS among Medical Students in Jordan

The stigmatizing attitude towards people living with HIV/AIDS (PLWHA) can be a major barrier to effective patient care. As future physicians, medical students represent a core group that should be targeted with focused knowledge and adequate training to provide patient care without prejudice. The aim of the current study was to examine HIV/AIDS knowledge, and the stigmatizing attitude towards PLWHA, among medical students in Jordan. The current study was based on a self-administered online questionnaire, which was distributed during March-May 2021, involving students at the six medical schools in Jordan, with items assessing demographics, HIV/AIDS knowledge, and HIV/AIDS stigmatizing attitude, which was evaluated using the validated HIV-stigma scale. The total number of respondents was 1362, with predominance of females (n = 780, 57.3%). Lack of HIV/AIDS knowledge among the study participants was notable for the following items: HIV transmission through breastfeeding (40.8% correct responses), HIV is not transmitted through saliva (42.6% correct responses), and vertical transmission of HIV can be prevented (48.8% correct responses). Approximately two-thirds of the respondents displayed a positive attitude towards PLWHA. For six out of the 14 HIV/AIDS knowledge items, lack of knowledge was significantly correlated with a more negative attitude towards PLWHA. Multinomial regression analysis showed that a significantly more negative attitude towards PLWHA was found among the pre-clinical students compared to the clinical students (odds ratio (OR): 0.65, 95% confidence interval (CI): 0.43-0.97, p = 0.036); and that affiliation to medical schools that were founded before 2000 was associated with a more positive attitude towards PLWHA compared to affiliation to recently founded medical schools in the country (OR: 1.85, 95% CI: 1.42-2.42, p < 0.001). About one-third of medical students who participated in the study displayed a negative attitude towards PLWHA. Defects in HIV/AIDS knowledge were detected for aspects involving HIV transmission and prevention, and such defects were correlated with a more negative attitude towards PLWHA. It is recommended to revise the current medical training curricula, and to tailor improvements in the overall HIV/AIDS knowledge, which can be reflected in a more positive attitude towards PLWHA, particularly for the recently established medical schools in the country.

Attitude towards HPV Vaccination and the Intention to Get Vaccinated among Female University Students in Health Schools in Jordan

Cervical cancer is a leading cause of morbidity and mortality in women worldwide. The availability of prophylactic vaccines for high-risk types of human papillomavirus (HPV) infection represents an important advancement in the prevention of cervical cancer. In Jordan, the availability of the HPV vaccination is restricted to individuals who are willing to pay. The aim of the current study was to evaluate the willingness and attitude of female university students in health schools/faculties in Jordan to get HPV vaccination and their knowledge about the virus. A self-administered online questionnaire was distributed in October 2021, which comprised 27 items to evaluate HPV knowledge, history of HPV vaccination, intentions to get the HPV vaccine, and the reason(s) behind vaccine refusal for those who rejected vaccination. The study sample comprised 836 participants: medical students (39.7%), pharmacy students (26.0%), dental students (21.2%), and nursing students (13.2%). Only 524 participants had heard of HPV prior to the study (62.7%), of which 48.7% knew about the availability of HPV vaccines. The lowest level of HPV knowledge was observed among nursing students. Only 19/524 students reported a history of HPV vaccination (3.6%). The overall willingness to receive HPV vaccination if provided freely was 75.0%, while only 16.0% were willing to pay for the vaccine. The most common reason for HPV vaccine rejection was the perceived low risk to get HPV infection. Significantly higher intentions to get HPV vaccination were found among older participants and medical students. The embrace of vaccine conspiracy beliefs was associated with a significantly less willingness to get the HPV vaccination (p < 0.001). Dependence on the internet/social media as the source of HPV knowledge was associated with a significantly lower intention to get HPV vaccination (p = 0.002). The coverage of the HPV vaccination among female university students in health schools in Jordan appeared extremely low; however, three-fourths of the students who had heard of HPV were willing to receive the HPV vaccination if provided freely. Complacency appeared as a major factor for HPV vaccine rejection. Increasing the levels of knowledge and awareness of HPV infection and its association with cervical cancer through reliable sources is recommended. This can be helpful for the individual benefit of the students besides the potentially positive role they can play in community education. Countering vaccine conspiracy beliefs with proper education and awareness programs can be helpful to appraise the role of HPV vaccines in cancer prevention.
