Yang YH. Current advances of oral cancer in Taiwan. Oral Dis 2024. [PMID: 39072913 DOI: 10.1111/odi.15076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 07/01/2024] [Accepted: 07/08/2024] [Indexed: 07/30/2024]
Abstract
OBJECTIVES To provide updated statistics of oral cancer incidence and mortality in Taiwan, and to describe recent developments for oral cancer control to reduce oral cancer incidence and mortality. METHODS The Taiwan Cancer Registry Annual Report 2023, the Taiwan Cancer Registry Online Interactive Search System, and the 2023 Health Promotion Administration Annual Report are consulted and summarized. A literature search using PubMed was also conducted to identify Taiwan oral cancer control-related studies. RESULTS Taiwan, with a long history of areca/betel quid chewing, has battled with oral cancer for decades. In 2021, the male lip and oral cavity cancer incidence is 29.77 (per 100,000 persons) and mortality is 11.25. Over these years, the male chewing prevalence was reduced to 6.2% in 2018. Taiwan has a sustained national oral cancer screening programme provided to high-risk groups biennially. CONCLUSIONS Although the age-standardized incidence rates have been slowly decreasing since 2009, due to Taiwan's ageing population, the actual oral cancer burden is still stringent. The collaboration of multi-ministries and agencies on promoting areca nut and betel quid control, improving oral cancer awareness, and delivering cancer care remains essential to prevent oral cancer and reduce oral cancer deaths.

Abstract
Importance Head and neck cancers (HNCs) are often diagnosed at advanced clinical stages during their symptomatic phase, leading to a reduced treatment window and poor survival. Screening programs have been suggested as a mitigation strategy. Objective To examine the effectiveness of current HNC screening programs in improving diagnosis and survival in adults. Evidence Review This Preferred Reporting Items for Systematic Reviews and Meta-analyses-guided systematic review involved use of peer-reviewed, English-language journal articles identified from MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials between January 1, 2001, and July 15, 2022. Snowballing was applied to retrieve more studies. Eligible articles were original clinical trials and observational studies presenting a universal or risk-targeted screening program of primary HNC in the adult population. Reporting quality was assessed using the JBI's critical appraisal tools. Findings Database searches yielded 3646 unique citations with an additional 8 studies found via snowballing. Five reviewers assessed the full text of 106 studies. Sixteen articles were ultimately included in the review, involving 4.7 million adults (34.1%-100% male; median age, 30-59 years). Fifteen studies were based in Asia and 1 in Europe (Portugal). Five reported data from randomized clinical trials. An oral inspection conducted once or once every 2 to 3 years was described in 11 studies for screening oral cancer, while multistep screening involving Epstein-Barr virus serologic testing for nasopharyngeal carcinoma delivered every 1 to 4 years was presented in 5. In 4 trials and 6 observational studies, screening significantly increased the detection of localized (stage I/II) tumor or was associated with an increased proportion of diagnoses, respectively, regardless of the population and cancer subsites. Universal screening of asymptomatic adults improved 3- to 5-year overall survival but did not increase cancer-specific survival in 4 trials. Targeted screening improved overall and cancer-specific survival or was associated with improved survival outcomes in 2 trials and 2 observational studies, respectively. Studies had low to medium risks of bias. Conclusions and Relevance Evidence from the existing literature suggests that a risk-targeted screening program for oral and nasopharyngeal cancers could improve diagnosis and patient survival. Screening adherence, societal cost-effectiveness, and optimal risk stratification of such a program warrant future research, especially in low-incidence settings outside Asia.

Smokeless tobacco use and oral potentially malignant disorders among people living with HIV (PLHIV) in Pune, India: Implications for oral cancer screening in PLHIV. PLoS One 2022; 17:e0270876. [PMID: 35788753 PMCID: PMC9255739 DOI: 10.1371/journal.pone.0270876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 06/17/2022] [Indexed: 01/12/2023] Open
Abstract
INTRODUCTION In India, smokeless tobacco (SLT) is a predominant form of tobacco used among people living with HIV (PLHIV). Despite SLT being a risk factor for oral potentially malignant disorders (OPMDs), no prior studies have quantified the association of OPMDs with SLT use among PLHIV. This limits the planning of preventive and control strategies for oral cancer among PLHIV, who are at higher risk for the disease. METHODS We enrolled 601 PLHIV and 633 HIV-uninfected individuals in an oral cancer screening study at BJ Government Medical College, Pune, India. Oral cavity images were collected using an m-Health application and reviewed by three clinicians. Participants with two clinician positive diagnoses were deemed to have suspected OPMDs. Prevalence ratios (PRs) were used to quantify the association between suspected OPMDs and SLT use among PLHIV. PRs for current SLT users, across HIV status and use duration were also estimated. Corrected PRs were obtained by modifying the maximum likelihood estimation. Models were adjusted for age, smoking, alcohol use and CD4 counts. RESULTS Of those enrolled, 61% were men, median age was 36 years (IQR: 28-44), and 33% currently use SLT. Proportion of current SLT users was similar across PLHIV and HIV-uninfected groups but use duration for current SLT use was higher among PLHIV(p<0.05). Among PLHIV, current SLT users had a 5-times (95% CI:3.1-7.0) higher prevalence of suspected OPMDs, compared to non-users. Relative to HIV uninfected individuals with the same SLT use duration, significant associations with suspected OPMDs were seen for PLHIV with<10 use years (PR: 3.5, 95% CI: 1.5-8.1) but not for PLHIV with≥10 use years (PR: 1.3, 95% CI: 0.9-1.8). CONCLUSION PLHIV that are current SLT users are at high risk of OPMDs and potentially oral cancer. The development of strategies for screening, early detection, and management of OPMDs must be considered for this group.

J Family Med Prim Care 2020; 9:4381-4385. [PMID: 33110864 PMCID: PMC7586626 DOI: 10.4103/jfmpc.jfmpc_535_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 04/26/2020] [Accepted: 05/11/2020] [Indexed: 12/03/2022] Open
Abstract
Background: Mouth self-examination (MSE) is shown as a speedy, economical, and effortless method of oral cancer detection. As previous studies were conducted in population with high literacy, the current survey was performed to explore the usefulness of MSE for finding the oral cancerous precancerous lesions in indigenous low literate population of Dehradun district. Materials and Methods: It is a cross-sectional survey which was done on the Buksa tribal communities in Dehradun district, India. Out of seven tehsils in the district, two were randomly selected, from which two villages were selected. Individuals belonging to Buksa tribe above the age of 18 years were gathered in commonplace. A total of 539 people who gave their consent were enrolled for study. Using a questionnaire, information regarding sociodemographic details, history of risk factors, and practice of MSE was obtained by interview method, followed by recording oral findings by a single expert. Later, performance of MSE was taught to the participants and they were asked to record the same. Descriptive analysis and Chi-square test were applied wherever applicable and significance level was kept at below 0.05. Results: It was observed that out of 539 participants, 220 (40.8%) practiced MSE and 319 (59.2%) have never practiced MSE. Further analysis showed that a total of 39% males and 42.7% females had MSE habits and this difference was not statistically significant (P > 0.05). In totality, the prevalence of oral lesions identified by health worker was 213 (39.5%), whereas MSE showed only prevalence rate of 69 (12.8%). MSE had low sensitivity (24.6%), whereas high specificity (87.4%) for all the lesions and most sensitive in detecting ulcers (72.7%), and highest specificity in identifying red lesions (99.2%). Conclusion: Even though the sensitivity of MSE for detecting oral premalignant/malignant lesions was low, specificity was very high. Frequent efforts to educate and encourage public on MSE may enhance efficacy and compliance.

Abstract
OBJECTIVES To evaluate the efficacy of mouth self-examination (MSE) as a self-screening tool for detection of oral mucosal lesions among an Indigenous population in Malaysia at high risk for oral premalignant and malignant disorders. METHODS Two villages were selected as the sampling frame based on prevalence of tobacco and betel quid chewing habit. Respondents were asked to check their mouth for presence of lesion or abnormalities. Education on oral cancer, including MSE, was provided. Subsequently, respondents were asked to perform MSE. Finally, a clinical oral examination (COE) was done by a specialist and the presence of oral mucosal lesions was recorded. RESULTS Almost 64.5 percent of respondents exhibited high levels of difficulty and low mucosal visualization and retracting ability, whereas 3.0 percent demonstrated high attention level when performing MSE. Prevalence of oral mucosal lesions was 59.0 percent, whereas the prevalence of oral potentially malignant disorders (OPMDs) was 9.0 percent. Detection of oral lesions by respondents using MSE was lower than detection by the gold standard. Sensitivity and specificity of MSE for detection of all types of lesions were 8.6 and 95.0 percent respectively. When analyzing each lesion type separately, MSE was found to be most sensitive in detection of swellings (10.0 percent), and most specific in identifying white lesions (97.8 percent). For detection of OPMDs, although specificity was high (98.9 percent), sensitivity (0 percent), and +LR (0) was poor. CONCLUSION MSE is not an effective self-screening tool for early detection of potentially malignant lesions for this population.

Abstract
PURPOSE OF REVIEW This article reviews the current literature and summarizes the latest developments in screening and early detection of oral cancers and looks at the future possibilities. RECENT FINDINGS Oral cancer is the best model for screening and prevention. The screening for oral cancer can be population based, opportunistic, or targeted. A long-term 15-year follow-up data of a randomized controlled study from a developing country setting indicated a sustained reduction in oral cancer mortality in high-risk individuals. Visual oral examination remains the mainstay in the screening. Several adjunctive techniques have been described to aid in the clinical examination of these lesions. A Cochrane review revealed that there is no evidence to recommend these adjuncts in clinically visible lesions. Salivary biomarkers seem to be promising as a tool for screening in the future. A Targeted Evidence Update for the US Preventive Services Task Force found no evidence on screening either in the general or selected high-risk population for oral cancer in the United States or on benefit of any adjunctive device affecting the performance of the screening examination. SUMMARY Current evidence shows that community based screening has a value in reducing the oral cancer mortality in high-risk group of population. But this evidence may not be universally applicable.

Abstract
Data collected and generated by radiation oncology can be classified by the Volume, Variety, Velocity and Veracity (4Vs) of Big Data because they are spread across different care providers and not easily shared owing to patient privacy protection. The magnitude of the 4Vs is substantial in oncology, especially owing to imaging modalities and unclear data definitions. To create useful models ideally all data of all care providers are understood and learned from; however, this presents challenges in the guise of poor data quality, patient privacy concerns, geographical spread, interoperability and large volume. In radiation oncology, there are many efforts to collect data for research and innovation purposes. Clinical trials are the gold standard when proving any hypothesis that directly affects the patient. Collecting data in registries with strict predefined rules is also a common approach to find answers. A third approach is to develop data stores that can be used by modern machine learning techniques to provide new insights or answer hypotheses. We believe all three approaches have their strengths and weaknesses, but they should all strive to create Findable, Accessible, Interoperable, Reusable (FAIR) data. To learn from these data, we need distributed learning techniques, sending machine learning algorithms to FAIR data stores around the world, learning from trial data, registries and routine clinical data rather than trying to centralize all data. To improve and personalize medicine, rapid learning platforms must be able to process FAIR “Big Data” to evaluate current clinical practice and to guide further innovation.
