Oesophageal Cancer
12 January 2024
Introduction
Oesophageal cancer was the twentieth commonest cancer in Hong Kong, accounting for 1.0% of all new cancer cases in 2021.
Incidence
There were 397 new cases of oesophageal cancer in 2021, with 325 male cases and 72 female cases. The disease was more common among male population and the male to female ratio of incidence was about 4.5 to 1. The crude incidence rates of oesophageal cancer were 9.6 for males and 1.8 for females per 100 000 population of respective sex. The age-standardised incidence rates* of oesophageal cancer were 4.4 for males and 0.8 for females per 100 000 standard population.
Trend of incidence
The age-standardised incidence rate of oesophageal cancer of both sexes, males and females all had a downward trend over the past 39 years (average annual percentage change (AAPC)# between 1983 and 2021: -4.3%, -4.2% and -4.7% respectively) and over the past 10 years (AAPC between 2012 and 2021: -4.3%, -4.2% and -4.7% respectively).

Mortality
Oesophageal cancer caused 286 deaths in 2022, accounting for 1.9% of all cancer deaths. It was the tenth leading cause of cancer deaths in Hong Kong. The crude death rates of oesophageal cancer were 6.8 for males and 1.4 for females per 100 000 population of respective sex. The age-standardised death rates* of oesophageal cancer were 2.9 for males and 0.6 for females per 100 000 standard population.
Trend of mortality
The age-standardised death rate of oesophageal cancer of both sexes, males and females all had a downward trend over the past 42 years (average annual percentage change (AAPC)# between 1981 and 2022: -3.5%, -3.4% and -3.8% respectively) and over the past 10 years (AAPC between 2013 and 2022: -4.3%, -4.1% and -4.8% respectively).
