Cancer of the colon and rectum (also known as colorectal cancer) is the most common cancer in Hong Kong. In 2018, there were 5,634 new cases of colorectal cancer in Hong Kong, accounting for 16.6% of the total number of new cancer cases in Hong Kong, which is 75.6 new cases of colorectal cancer per 100,000 population. With the advancement in clinical technology, the early detection of colorectal cancer could significantly improve treatment success. The five-year relative survival rate of patients with stage 1 and stage 2 colorectal cancer is very high, 96% and 87%, respectively.
With the donation from the Hong Kong Jockey Club Charities Trust, the University of Hong Kong (HKU) launched the "Jockey Club Colon Cancer Prevention and Screening Program" and established the HKU Endoscopy Center to conduct clinical research for members of high-risk families with colorectal cancer. Through clinical research, including genetic and microbiota analysis, the Endoscopy Center hopes to find out the causes and high-risk factors of colorectal cancer and help the public to understand colorectal cancer further.
