title: [A prospective study on the relationship between nutrition intervention and incidence of malignant tumors in Lin County, China].
abstract: OBJECTIVE
  To analyze the tendency in the incidence of malignant tumors in nutrition-intervened population of Lin County.
  
  
  METHODS
  Subjects who had been enrolled in the General Population Trial, Lin County Nutrition Intervention Trial were followed up and the data of malignant tumors were collected with collaboration of National Cancer Institute/National Institute of Health. Incidences of malignant tumors during and after nutrition intervention were calculated and compared.
  
  
  RESULTS
  Esophageal cancer, cardiac cancer, and stomach cancer were constantly the three leading cancers, accounting for 84.06% and 83.74% of the malignant tumors in men and women, respectively. The incidences of lung cancer and liver cancer in men showed increasing tendencies, while similar tendencies were found in those of stomach cancer, colorectal cancer, and liver cancer in women. With the prolonging of the follow-up, the incidences of upper digestive tract cancers declined (except stomach cancer in women).
  
  
  CONCLUSIONS
  The upper digestive tract cancers remain the leading malignant tumors, although their incidences may decline with longer-term follow-up. Prevention and control of tumors in Lin County should still be focused on the esophageal cancer, cardiac cancer, and stomach cancer, as well as lung cancer and liver cancer.
