Abstract
INTRODUCTION: We present an epidemiological description of cancer of the lip, oral cavity, and oropharynx focused on South and South-East Asia by cancer site, sex, and population. METHODS: The number of new cases and deaths from lip, oral cavity, and oropharynx cancers was extracted from GLOBOCAN 2022 and Cancer Incidence in Five Continents. We present age-standardized incidence and mortality rates (ASR) per 100,000 and temporal trends between 1992 and 2017 for four populations in the Region. RESULTS: In 2022, there were 177,258 incident cases and 98,735 deaths from oral cancer in this region. ASR for lip and oral cancer in South and South-East Asia was highest in India (14.67), Sri Lanka (14.04), Bangladesh (13.61) and Pakistan (12.07) in males. The highest age-standardized mortality rates for lip and oral cancer were observed in India (8.17), Bangladesh (8.07) and Pakistan (7.74) for males. CONCLUSION: Incidence and mortality rates of oral cancer in South and South-East Asia are among the highest globally. 52% of total global deaths from oral cancer are reported from this region. Data suggest a persisting trend and an increase in the incidence of oral cavity cancer among Indian and Bangladeshi males.
