Oral Cancer Screening

Abstract Background: Oral cancer is a major public health challenge, and about one-fifth of all oral cancer cases reported globally are from India. In spite of the potential for early detection by simple visual examination, the majority of patients report in later stages of the disease, especially in low and middle-income countries. We report the results from a district level population-based oral cancer screening program. Methods: A cross-sectional survey was carried out among people aged >15 years in 48 panchayats of Kannur district in Kerala, India. This comprehensive multi-stakeholder district-wide screening was carried out in six stages including planning, sensitization, recruiting of community volunteers and training, survey, organization of specialist camps and referring to cases to cancer center. The descriptive statistical analysis was performed using EpiData analysis software (Version 2.2.2.180). Results: Among the 1,061,088 people in 265,272 houses surveyed, 2507 of them attended the screening camps, and 13 oral cancers and 174 oral precancers were detected. Majority of the oral cancer patients were male (69%), with primary education or illiterate (62%) and low socioeconomic status (61%). Five of the patients diagnosed with early-stage cancer are alive and have good oral health-related quality of life. Conclusion: Detection of precancerous and early-stage cancers should be a priority of oral cancer screening programs. The possible key for addressing cancer screening needs of the rural population is to equip the primary health centers in cancer screening activities with available human resources while adapting to local context.

Oral Cancer Screening

Management of advanced-stage oral cancer adds a great burden to individuals and health care systems. Community-based oral cancer screening can be beneficial in early detection and treatment. In this study, a novel oral cancer screening program was conducted utilizing an existing network of health care personnel, facilities, and digital database management for efficient coverage of a large population. The screening program considered 392,396 individuals aged ≥40 from four northeastern provinces in Thailand. Three levels of screening were performed: S1 by village healthcare volunteers to identify risk groups, S2 by dental auxiliaries to visually identify abnormal oral lesions, and S3 by dentists for final diagnosis and management. A total of 349,318 individuals were interviewed for S1, and 192,688 were identified as a risk group. For S2, 88,201 individuals appeared, and 2969 were further referred. Out of 1779 individuals who appeared for S3, oral potentially malignant disorders (OPMDs) were identified in 544, non-OPMDs in 1047, doubtful lesions in 52, and no results in 136 individuals. Final treatment was carried out in 704 individuals that included biopsies of 504 lesions, exhibiting 25 cancerous lesions and 298 OPMDs. This study is so far one of the largest oral cancer screening programs conducted in Thailand and showed effective implementation of community-based oral cancer screening.

Oral Cancer Screening

Background: Oral cancer is a major public health burden in Taiwan. Studies have suggested that habits of betel quid chewing, tobacco smoking and alcohol drinking as well as their interaction effects are important risk factors for oral cancer and oral potentially malignant disorders (OPMD). A population-based oral cancer screening program has been implemented by Health Promotion Administration, Ministry of Health and Welfare, Taiwan. People with betel quid chewing and/or cigarette smoking habits are recommended for biennially screening. Previous studies found that majority of betel quid chewers were in labor intensive occupations. Given the fact that high risk groups of oral cancer are often reluctant to attend screening, targeted approach should be applied to improve the effectiveness of screening program. Aim: The aims of this study are to identify occupations with high prevalence of betel-quid chewing and also to investigate changing trends using the National Health Interview Survey (NHIS) database. Methods: The NHIS database of 2009 and 2013 were used to conduct this study. We identified current users of betel quid and/or cigarette from adults with aged 20-64 years old and working on jobs. Occupations were classified using the International Standard Classification of Occupations (ISCO-88). Statistical analyses included indirect standardized rate ratios and cluster analysis of chewing/smoking habits. Results: From the total survey participants (2009: 19,201, 2013: 17,249), we extracted 11,507 and 10,760 persons for the study. In the year of 2013, using the 2-digit code of ISCO-88, drivers and mobile-plant operators (code 83 in ISCO-88) had the highest prevalence of betel quid chewing habit (30.9%), followed by extraction and building trades workers (code 71 in ISCO-88, 29.6%). These two groups also had the 2 highest smoking prevalence (61.2% and 62.2%). The betel quid chewing prevalence decreased from 2009 to 2013 slightly (32.3%-30.9%). However, the prevalence of smoking increased (60.0%-62.2%). Among the betel quid chewers of the two focused occupations, the corresponding rates of receiving oral cancer screening were rather low (35.47% and 21.52%). The indirect standardized ratios using the total sample as the reference showed 6 occupations (2 digit of ISCO-88) with significantly higher ratios (larger than 2). Cluster analysis demonstrated that the group with high prevalence of betel quid chewing also had high prevalence of cigarette smoking habit. Conclusion: The betel quid chewing prevalence has been decreased in all occupations. While at the same time, prevalence of cigarette smoking did not largely decrease. We analyzed the NHIS databases and found that workers in some occupations tend to have higher prevalence in both betel quid chewing and smoking. The oral cancer screening and cancer awareness need be targeted on certain occupations.

Oral Cancer Screening

Background: Pap smear screening was the first nation-wide population-based organized screening since 1999 in Taiwan. After that, nationwide screening programs for breast cancer, colorectal cancer, and oral cancer have been launched since 2004. The national online information system was built for the infrastructure, monitoring, delivery, evaluation, and management of health care services in our nationwide screening program. Aim: To develop a comprehensive health information system for cancer screening to assist health professionals in processing screening with quality assurance and evaluation. Methods: A Web-based solution combining data gathering and processing capabilities was developed. Application design in a server was based on the ASP, HTML, DHTML, Java Script, Java Applet technology and SQL-SERVER relational database. Web-based software programs were developed to facilitate the structure, process, and outcome for screening. Individual screening data were transferred to centralized databases via the Internet. The client-users now include 25 health bureaus, 369 health centers and over 6500 clinics or hospitals. Results: The Taiwanese cancer screening system incorporates nationwide breast cancer screening with mammography, colorectal cancer with fecal immunochemical test, oral cancer with visual inspection. The key performance index for screening including screening rate, positive rate, referral rate, positive predictive rate, detection rate, and interval cancer rate were provided in the system. The system allows for the flow of information among different health services and country areas to monitor participants in the whole process screening. It has an alert system to prevent delayed referral for cases in need of diagnosis and treatment. A total of 2.27 million women aged 45-69 years have attended biennial mammography screening program at least once between 2004 and 2014. More than 4.6 million subjects with the exposure of betel quid and/or cigarette have attended the biennial oral cancer screening. Around 3.8 million subjects aged 50-74 years have attended the biennial FIT screening. Information on organized features appertaining to screening, diagnosis, and outcomes after long-term follow up were collected for the systematic evaluation. The proposed health information system for cancer screening is centered on modules that would allow for the computerization, process, update of screen data, and link with other registry data (e.g., population registry, cancer registry, and mortality). Conclusion: A nation-wide information system for breast cancer, colorectal cancer, and oral cancer screening was successfully developed to support health professionals and health decision makers for planning, delivery, management, and evaluation in population-based cancer screening program.

Delay In Treatment

Background: Previous studies have indicated the issue of delay treatment in patients diagnosed as oral cancer in population-based screening because oral cancer patients often lack the knowledge to understand rapid progress of oral cancer. Aim: To evaluate the impact of delay in treatment on the survival of oral cancer detected by screening. Methods: We enrolled residences aged 18 years or older with cigarette smoking and/or betel quid chewing who attended Nationwide Oral Cancer Screening program between 2004 and 2009. Cases with prior history of oral cancer were excluded. Demographic characteristics, oral habits, time of delay in treatment after screening and cancer stage were collected. The survival status of oral cancer was ascertained by following up this cohort until the end of 2012. Results: A total of 6353 oral cancers were detected by screening with a median of 19 (interquartile range 12 to 29) days for treatment. Oral cancer with earlier clinical stage had less delay in treatment ( P < 0.01) while gender, age, and diagnostic year had no difference in delay. In univariate analysis, older age (hazard ratio, HR = 1.01), clinical stage (HR = 1.96 for stage II, 3.13 for stage III, 6.42 for stage IV as compared with stage I), and delay in treatment after screening longer than 3 weeks (HR = 1.11) or 6 weeks (HR = 1.64) were highly associated with worse prognosis. In multivariate analysis, delay in treatment more than 6 weeks (HR = 1.34, 95% CI 1.21-1.48) led to poor survival of oral cancer. Conclusion: Subjects with cigarette smoking and/or betel quid chewing who attended oral cancer screening and were detected as oral cancer patients should be advised to undergo treatment no more than 6 weeks.
