Public awareness of oral cancer among adults in Jakarta, Indonesia

Oral Cancer Awareness of Tertiary Education Students and General Public in Singapore

OBJECTIVES

Oral cancer confers high morbidity and mortality rates. Late diagnosis of oral cancer is linked to a lack of awareness of its existence and known risk factors. The purpose of this survey was to examine the knowledge and awareness of oral cancer amongst different groups in Singapore.

METHODS

A self-administered questionnaire (including questions on awareness, risk factor knowledge, and health beliefs about oral cancer) was distributed to undergraduate students from the medical and dental schools and other faculties at the National University of Singapore, as well as the general public.

RESULTS

A total of 470 responses were analysed. Both medical and dental students were almost universally aware of the disease and correctly identified recognised risk factors for oral cancers. Dental students had a significantly higher level of knowledge of chewing betel quid as a risk factor than medical students (98% vs 74%; P < .0001), although 1 in 10 dental students did not identify alcohol as a risk factor. In contrast, undergraduate students from other faculties were the least aware of oral cancer (62%). Within the general public, knowledge of the risk factors of oral cancer aside from smoking was low, with only 41% aware of viruses as a possible aetiology. However, the younger population group, aged 18 to 34 years old, in general had better knowledge of the risk factors of oral cancer compared with older participants.

CONCLUSIONS

There is a general lack of awareness about oral cancer and its associated risk factors amongst certain cohorts of the Singapore population. There exists room for further targeted education.

Estimated projection of oral squamous cell carcinoma annual incidence from twenty years registry data: a retrospective cross-sectional study in Indonesia

Background

The incidence of oral squamous cell carcinoma (OSCC) has not been well documented in Indonesia. Thus, we aimed to analyze trends and clinicopathological profiles of OSCC cases in Indonesia, focusing on differences between age and sex groups.

Methods

A cross-sectional study was conducted in Indonesia's main referral hospital, analyzing 1,093 registered OSCC cases from 2001 to 2020. Trend analysis was performed using Joinpoint regression analysis to determine the annual percentage change (APC) for overall cases and each case group based on age, sex, and anatomical subsites. APC significance was assessed using a Monte Carlo permutation test. The projection of case numbers for the following 5 years (2021-2025) was estimated using linear/non-linear regression analysis and presented as a mathematical function. The significance of the trend slope was measured using an ANOVA test. Demographic and clinicopathological characteristics of OSCC were analyzed according to age and sex, and their comparative analysis was assessed using Chi-square and its alternatives.

Results

The incidence of OSCC in female patients and in the tongue and buccal mucosa showed a positive trend (APC 2.06%; 3.48%; 8.62%, respectively). Moreover, the incidence of OSCC overall, and in women with OSCC, is projected to increase significantly in the next 5 years following the quadratic model. The mean age of patients was 51.09 ± 14.36 years, with male patients being younger than female patients. The male-to-female ratio was 1.15, and 36.5% of these patients were categorized as young (≤45 years old). The tongue was the predominantly affected site. Prominent pathologic characteristics included well-differentiation, keratinization, and grade I of Bryne's (1992) cellular differentiation stage. Most patients presented with advanced staging, lymphovascular invasion, and uninvaded margins. Tumor sites and staging varied according to age, while age and tumor sites differed between sexes.

Conclusion

The rising incidence trends of OSCC among Indonesian patients, both in the past and projected future, are concerning and warrant attention. Further research into risk factors should be conducted as preventive measures.

The duration of intervals on the oral cancer care pathway and implications for survival: a systematic review and meta-analysis

Introduction

Previous studies measuring intervals on the oral cancer care pathway have been heterogenous, showing mixed results with regard to patient outcomes. The aims of this research were (1) to calculate pooled meta-analytic estimates for the duration of the patient, diagnostic and treatment intervals in oral cancer, considering the income level of the country, and (2) to review the evidence on the relationship of these three intervals with tumor stage at diagnosis and survival.

Materials and methods

We conducted a systematic review with meta-analysis following PRISMA 2020 guidelines (pre-registered protocol CRD42020200752). Following the Aarhus statement, studies were eligible if they reported data on the length of the patient (first symptom to first presentation to a healthcare professional), diagnostic (first presentation to diagnosis), or treatment (diagnosis to start of treatment) intervals in adult patients diagnosed with primary oral cancer. The risk of bias was assessed with the Aarhus checklist.

Results

Twenty-eight studies reporting on 30,845 patients met the inclusion criteria. The pooled median duration of the patient interval was 47 days (95% CI = 31-73), k = 18, of the diagnosis interval 35 days (95% CI = 21-38), k = 11, and of the treatment interval 30 days (95% CI = 23-53), k = 19. In lower-income countries, the patient and treatment intervals were significantly longer, and longer patient intervals were related to later stage at diagnosis. In studies with a lower risk of bias from high-income countries, longer treatment intervals were associated with lower survival rates.

Conclusion

Interval duration on the oral cancer care pathway is influenced by the socio-economic context and may have implications for patient outcomes.

Factors associated with follow-up attendance of patients with oral squamous cell carcinoma: A retrospective cohort study

BACKGROUND

This study examined the postoperative follow-up attendance of oral squamous cell carcinoma (OSCC) patients, evaluated some of the factors associated with it, and assessed its relationship with early detection of postoperative disease progression.

METHODS

An exploratory retrospective cohort study of 430 OSCC patients was conducted. We examined associations of follow-up attendance within the first year after surgery with selected demographic and clinical factors, and with early detection of disease progression.

RESULTS

The mean number of follow-up visits within the first year after surgery was 3.9 out of the 12 recommended at our center; few patients were fully adherent. Age ≥70 years, unmarried status, high education level, and negative history of surgery for premalignant or malignant lesions from oral cavity or other sites were significantly associated with lower follow-up attendance. Greater follow-up attendance was significantly associated with early detection of disease progression during the first year after surgery (p = 0.025).

CONCLUSIONS

Adherence to follow-up visits was poor. Several sociodemographic and clinical factors were related to follow-up attendance, greater follow-up attendance was significantly associated with early detection of disease progression, and these should be further explored in future research.

Assessment of Knowledge of and Attitude Toward Oral Cancer Among the Outpatient Population in a Tertiary Care Rural Hospital

Introduction Lack of knowledge and awareness about oral cancer and its risk factors and negligence of the early warning signs play a crucial role in raising the incidence of the disease. Therefore, the aim of this present study is to assess the awareness of oral cancer among the local population regarding the prevalence, etiology, early signs of oral cancer, and treatment options available for the same. Materials and methods  The study was approved by the institutional ethics committee. A cross-sectional study was done on 158 patients from 15-70 years. The questionnaire comprised closed-ended questions to assess the subject's awareness, knowledge, and attitude toward the prevalence, causative factors, early signs that suggest oral cancer, and treatment options available for oral cancer. Results The study population consisted of 61% females and 39% males; the participants were aged between 15 and 70 years and the majority of them belonged to the 46-60-year age group (39.2%). Most of the participants (46%) had completed secondary education. Thirty-two point nine percent (32.9%) had not heard about oral cancer, 43.7% considered tobacco chewing and smoking risk factors, but only 25.8% were aware of early signs of oral cancer. Individuals who were unaware of oral cancer were educated. Conclusion This is a simple method to understand the participants' knowledge of oral cancer and its risk factors. Based on the results, we can identify the populations that are unaware of oral cancer, and they can be educated regarding early screening, prevention, and control.

Cancer signs and risk factors awareness in Addis Ababa, Ethiopia: a population-based survey

BACKGROUND

There is a paucity of data on public awareness of cancer in Ethiopia. This study assessed cancer signs, symptoms, and risk factors awareness among individuals aged 18 and older in Addis Ababa, Ethiopia.

METHOD

A population-based face-to-face interview was conducted applying a validated cancer awareness measure (CAM) tool. A total of 600 adults (315 males and 285 females) were recruited using a multistage sampling technique. One open-ended and ten closed-ended questions were used to assess awareness of cancer signs and symptoms. To assess awareness of cancer risk factors, one open-ended and twelve closed-ended questions were used. Logistic regression analysis was used to test the association between sociodemographic status and awareness of cancer signs, symptoms, and risk factors.

RESULTS

Based on the responses for the open-ended questions, unexplained bleeding (23.16%) and smoking (24.17%) were the most frequently recalled cancer sign and risk factor, respectively. Based on the responses for the closed questions, the majority of respondents identified tiredness all the time (80.7%) as a cancer symptom and alcohol use (82.5%) as a cancer risk factor.  The odds of cancer signs and symptoms awareness was higher in those with primary (AOR = 4.50, 95% CI, 1.72-11.79, p = 0.02), secondary (AOR = 4.62; 95% CI 1.86-11.43; p = 0.001), and tertiary (AOR = 7.51; 95% CI 3.04-18.56; p < 0.001) education than those who were illiterate. The odds of awareness about cancer signs and risk factors was 0.28 (95% CI 0.12-0.65; p = 0.003) and 0.22 (95% CI 0.83-0.58; p = 0.002) times lower, respectively, among individuals aged 60 and older than those aged 18 to 29.

CONCLUSIONS

Young adults who attended formal education of primary or higher level may have a better cancer signs and symptoms awareness. Future education interventions to increase awareness of the society in Addis Ababa may target illiterate and the elderly.

Trend Analysis of Global Web Searches (2004–2022) on Oral Cancer and Its Major Risk Factors

Background Oral cancer is the 15th leading cause of mortality globally. The Internet is an online source of information pertaining to oral cancer and its major risk factors. This study aims to analyze the trend of global online interest on oral cancer and its major risk factors through an analysis of web searches of oral cancer.

Materials and Methods This study analyzed the web searches conducted, from 2004 to January 2022, on oral cancer and its major risk factors (tobacco use, harmful alcohol use, and human papillomavirus [HPV] infection) using data obtained from Google Trends.

Results Within the time frame under study, oral cancer had multiple peak search periods, with the highest relative search volume index (SVI) for a period being 1; the peak search period for alcohol was March 2020 (SVI = 100); the peak search periods for tobacco were March to April 2004 (SVI = 17); and the peak search period of HPV was April 2004 (SVI = 1). Globally, alcohol was the most common searched term among these four terms (oral cancer, alcohol, tobacco, and HPV) except in Turkey where tobacco was the most common (55%) searched term. The top 25 search queries for oral cancer, HPV, tobacco, and alcohol had SVI ranges of 22 to 100, 12 to 100, 28 to 100, and 18 to 100, respectively. From these search queries, it was observed that people have interest in oral cancer symptomatology, and the adverse effects of tobacco, alcohol, and HPV.

Conclusion This study revealed an overall decline in the online interest on oral cancer and its major risk factors on a global scale.

Oral Cancer Awareness and Individuals' Inclination to Its Screening and Risk Prediction in Hong Kong

Assessing the baseline knowledge status and expectations of the target population of any health promotion and secondary prevention program is essential to the success of such intervention. To obtain this information about the Hong Kong population a priori to implementing these preventive strategies for oral cancer in addition to determining the willingness of potential screening participants to take risk-profiling assessments, a cross-sectional survey was conducted between November 2019 and March 2020. A total of 964 residents between the ages 18 and 86 years were invited to participate in this study across the three geographical areas in Hong Kong. Most participants self-reported being aware of oral cancer (86.3%), although the proportion of those with substantial knowledge on salient risk factors and early identifiable signs were very low (2.9%). Age and level of education were the only demographic characteristics associated with the knowledge status. The proportion of participants willing to attend community screening and partake in risk profiling assessment was high (83.9% and 80.9% respectively). Willingness to attend community screening was directly associated with respondents' self-reported oral cancer awareness status (OR: 1.9, 95% CI: 1.22-2.96). Also, we observed that those participants who were willing to attend screening are more inclined to take risk prediction assessments that those not willing to attend. These findings have showcased the need to intensify health promotion via personal skills development to encourage early disease presentation and will assist in the planning of these programs accordingly in the Hong Kong population.

Assessment of the oral cancer control activities through care seeking behavior of hospital attendees and their level of awareness

Oral cancer is the most common cancer among males in the Sri Lankan population. The aim of this study was to assess the health seeking behaviors and associated factors for OPMD. A hospital based descriptive cross-sectional study was conducted among Out Patients Department attendees of the Institute of Oral Health, Maharagama, from July 1, 2018 to December 31, 2019 by administering a questionnaire followed by an intra oral examination. The total number of 110 OPMD/oral cancer patients were identified. Awareness on OPMD was that 40 ​%. Majority were unaware of the danger of areca nut and alcohol use. Out of the identified cases during oral examination, 47.3 ​% were incidental findings while only 7.3 ​% were referred by the General Medical Practitioners (GMP). None were referred by the Primary Health Care (PHC) staff. The level of awareness on OPMD and its risk factors were very low. Incidental findings during the dental screening being the main mode of detection of OPMD, highlights the importance of conducting opportunistic screening at dental settings. Implementation of the Risk Factor Model (RFM) approach for the early detection of oral cancer through PHC staff and GMP is validated to encourage more early referrals.

Knowledge and Practice Regarding Oral Cancer: A Study Among Dentists in Jakarta, Indonesia

Objective

To assess Indonesian dentists' knowledge of risk factors and diagnostic procedures related to oral cancer (OC) and to determine the factors that influenced their level of knowledge.

Methods

A modified version of a questionnaire that had been used to assess dentists’ knowledge regarding OC in Canada was used. A total of 816 dentists were invited to participate in the study.

Results

The total response rate was 49.2%; however, the number of dentists from 5 regions in Jakarta were equally represented. Use of tobacco or alcohol and history of previous OC were the top 3 risk factors that were answered correctly by dentists, but there was a high proportion of dentists who considered some without any evidence as risk factors. Almost half of the dentists did not know the early signs of OC and that erythroplakia and leukoplakia were associated with increased risks of developing OC. Only about 27% of dentists had a high level of knowledge of risk factors and fewer dentists demonstrated a good knowledge of diagnostic procedures. Dentists’ age group, year of graduation, and experience of continuing education significantly influenced the level of knowledge of diagnostic procedures (P < .05).

Conclusion

Dentists in Jakarta had a considerable level of knowledge of major risk factors of OC, although some gaps in their knowledge, especially in diagnostic procedures, were present. Increasing these competencies may aid in the prevention and early detection of OC.

Adolescents' Perceptions About Cancer and Preferences for Cancer Education

BACKGROUND

Cancer is one of the leading causes of death within the United States. Adolescence remains a critical stage of development in which new cognitive skills and lifestyle factors related to cancer are acquired. It is critical to understand adolescents' knowledge of cancer and preferences for receiving clear and easy-to-comprehend information about cancer and cancer prevention. The purpose of this study was to explore adolescents' perceptions of cancer and cancer risk factors and identify their preferences for receiving cancer prevention education.

METHODS

The survey used in this study was based on the Health Belief Model framework, the Youth Risk Behavior Survey, and the Cancer, Clear & Simple (CC&S) Curriculum. The survey evaluated adolescents' knowledge, attitudes, and health-related behaviors regarding cancer and cancer prevention among adolescents. Three Midwestern middle and high schools were recruited, and 235 students completed the survey. Survey responses were analyzed using descriptive statistics.

RESULTS

Study participants had some basic knowledge of cancer; however, only 66% recognized that individuals have control over their risk of developing cancer. Participants (95%) reported that cancer prevention was important, yet only 37.3% stated they knew how to lower their risk of getting cancer and 50% indicated that they currently try to make decisions that lower their chances of getting cancer. About 82% stated that an educational game would be a useful tool to learn about cancer and prevention.

CONCLUSION

Study findings indicate the need for an increase in adolescent knowledge of cancer, specifically how they can control their cancer risk, and prevention strategies through development of game-based education to teach adolescents about cancer-related topics.

Cancer Warning Symptoms Awareness and Associated Factors Among Individuals Living in Assella Town, Ethiopia

Introduction

Community awareness about cancer warning symptoms and risk factors in the general population is essential and can be considered as a basis for cancer control programs. Since Patients are rarely aware of the early warning symptoms and cancer risk factors, the burden of disease is increasing everywhere in the world. Evidences has been shown that cancer is highly prevalent in Ethiopia in which the diagnosis is made at later stages of the disease.

Objective

To assess Cancer Warning Symptoms awareness and associated factors among individuals living in Assella Town, Ethiopia.

Methods

A community-based cross-sectional study was employed in Assella town from May 1^st to June 1^st, 2020 among 410 adult residents 18 years old and above. A systematic random sampling technique was employed to select the households from which the study subjects randomly identified. Data were collected through face-to-face interview by using pre-tested structured questionnaire and entered into Epi data version 3.1 then exported to SPSS version 25.0 for analysis. Logistic regression analyses were used to identify factors associated with outcome variables. Odds ratio and 95% CI at P-values <0.05 was used to determine the presence of association.

Results

The findings of this study revealed that the overall level of awareness of cancer warning symptoms is 214 (52.2% (AOR = 95% CI 47.1, 56.8)). Educational level (AOR = 3.44, 95%CI, 1.50–7.88 (p = 0.003)), awareness of cancer risk factors (AOR = 2.56, 95% CI, 1.67, 3.93, (p < 0.001)) and economic status (AOR = 3.13 (95% CI 1.84, 5.33, p < 0.001)) were identified as factors significantly associated with awareness of cancer warning symptoms among adult populations.

Conclusion

Almost one-out-of-two adults residing in Assella town has awareness about cancer warning symptoms. Educational level, awareness of cancer risk factors, and economic status among Assella town residents were identified as factors associated with good level of awareness about cancer warning symptoms.

Oral cancer awareness among aged patients with chronic oral mucosal diseases in Russian Federation

The secret of longevity is not only in healthy lifestyle and genetics, but in the forehanded prevention of diseases. Nowadays the preservation of health is much more the patient’s responsibility. This mission can be realized only through the high level of patient’s awareness and treatment compliance. Oral cancer has one of the highest mortality rates among all malignancies worldwide. A gap in patient knowledge about oral cancer, specifically related to risk factors and signs and symptoms, is posited to be among the key modifiable factor contributing to high morbidity and mortality. The purpose of this study is to evaluate the oral cancer awareness among patients of the risk group (aged patients with chronic oral mucosal diseases). Results of the study showed the lack of oral cancer awareness among patients: the mean knowledge score for the risk factors – 3, 1 ± 1, 2 out of 8, 0, for the signs and symptoms – 4, 9 ± 1, 3 out of 12, 0. It was found that women had higher oncological awareness than men, as well as participants with high educational level, and patients with premalignant oral lesions (oral lichen planus, oral leukoplakia). Educational programs are essential for improvement of oral cancer awareness among population.
