Oral cancer incidence trends in Delhi (1990–2014): An alarming scenario

Abstract

Background: Oral cancer ranks in the top three of all cancers in India, which accounts for over 30% of all cancers reported in the country, and oral cancer control is quickly becoming a global health priority. We have conducted an age period analysis of oral cancer incidence trends using the Population-Based Cancer Registry (PBCR) data in Delhi over a 24-year period (1990–2014) to address the trends of one of the leading cancer sites in Delhi. Materials and Methods: The data of oral cancer proportion and incidence for the year 1990–2014 were taken from Delhi PBCR which records cancer cases from more than 180 government and 250 private facilities. The data were segregated by sex, age, and anatomical site and were analyzed to calculate age-specific incidence rates and expressed in cases per 100,000 persons/year. Results: The highest incidence for both genders was seen in the age group 50–59 years and the lowest incidence for both genders was in youngest age group (<20 years) for all the years from 1990 to 2014. The relative proportion of oral cancer among all types of cancer in Delhi has shown alarming rise from the year 2003 onward. Conclusion: Increasing relative proportion of oral cancer can be implicated in increased consumption of gutkha chewers in the last decade of the 20th Century. As access to health-care services and cancer-related awareness is highly variable in India, more in-depth analysis of the incidence of oral cancer in rural regions will be required.

Trend Analysis of Head and Neck Neoplasms between 2012–2018 in Patients Residing in Al-Madinah, Saudi Arabia: A Retrospective Study

“…This finding consolidates the findings of previous studies. 18,27 Age is a known risk factor for head and neck malignancies. 28 Like many developing nations, Al-Madinah population age-structure is most of younger cohorts.…”

Opportunistic Screening of Oral Potentially Malignant Disorders: A Public Health Need for India

“…The epidemic of OC reported 2 decades ago 75 has burgeoned and continues to grow at an explosive rate among young Indians, 50,76,77 and with an aging population, OC incidence is projected to increase. 27,78 The projected numbers of OC cases will impose huge family, societal, and economic burdens that are insurmountable for a low-resource country. This is also a barrier to achieving SDG 1 (to end poverty in all its forms everywhere) and SDG 3 (to ensure healthy lives and promote well-being for all at all ages).…”

“…22,23 Compared with the overall population growth, the elderly population (age ≥ 60 years) is growing three times faster in India, 24 and because the incidence of OC increases with age, 25,26 advancing age is a risk factor for OC in India. 25,27 According to a 3-year Population Based Cancer Registry (PBCR) of India report in 2016, mouth cancer was the leading cancer among males in 7 of 27 PBCRs, and tongue and mouth cancers together are projected to increase from 106,794 cases in 2015 to 144,357 cases in 2020. 6 This is a much larger increase than that projected by GLOBOCAN 2012 for India, which is from 77,000 cases in 2012 to 102,579 cases by 2020.…”

Validation of a Point-of-Care Optical Coherence Tomography Device with Machine Learning Algorithm for Detection of Oral Potentially Malignant and Malignant Lesions

“…Cancers of the oral cavity and lips account for approximately 377,713 new cancer cases with a mortality of approximately 177,757 cases worldwide [ 1 ]. India faces the highest age-adjusted incidence rate (15.2) and mortality rate (9.3), which could be attributed to the usage of tobacco and tobacco-related products [ 2 , 3 , 4 , 5 ]. More than 90% of the oral cavity cancers are oral squamous cell carcinoma (OSCC).…”
