title: [Incidence of colorectal cancer in Guangzhou City from 2000 to 2002].
abstract: OBJECTIVE
  The incidence of colorectal cancer is increasing with the change of the diet habit. This study was to analyze the incidence of colorectal cancer in Guangzhou City, thus to provide references and information for the prevention and treatment of this disease.
  
  
  METHODS
  Data of colorectal cancer patients during 2000-2002 were collected from Guangzhou population-based cancer registry. Incidence and mortality of colorectal cancer were calculated and analyzed.
  
  
  RESULTS
  The crude incidence and mortality of colon cancer in Guangzhou from 2000 to 2002 were 13.4 per 100000 (13.5 per 100000 in males, 13.3 per 100000 in females) and 7.1 per 100000 (7.3 per 100000 in males, 6.9 per 100000 in females), respectively. The crude incidence and mortality of rectal cancer in Guangzhou from 2000 to 2002 were 9.6 per 100000 (10.8 per 100000 in males, 8.2 per 100000 in females) and 5.0 per 100000 (5.5 per 100000 in males, 4.5 per 100000 in females), respectively. The incidence of colon cancer and rectal cancer ranked the fifth and seventh respectively among all cancers. The incidence of colorectal cancer was increased with age.
  
  
  CONCLUSIONS
  The incidence rate of colorectal cancer is high in Guangzhou. Studies on prevention and treatment of colorectal cancer should be enhanced.
