Trends in incidence and mortality of esophageal cancer from 1981 to 2002 in Tianjin / 中华消化杂志

ABSTRACT

Objective To investigate the trends in incidence and mortality of esophageal cancer from 1981 to 2002 in Tianjin,China and to predict future trends and facilitate future prevention.Methods All new cancer cases registered in the Tianjin Cancer Registry between 1981 and 2002 were reviewed.Yearly age-specific,crude and age-adjusted incidence rates were calculated for males and females.Secular trends of incidence and mortality were indicated by the estimated annual percentage change(EAPC).Results A total of 8206 cases of esophageal cancer were reported in Tianjin form 1981 to 2002,with 5533 males and before 45 years,but increased rapidly after 45 years.The median age of esophageal cancer cases was 69 years,with quartile range from 62 to 75 years.The peak for age specific incidence in females was 75-80 years,which was earlier than that in males(aged 80-85).But recent data indicated that the peak age in females had increased and became similar to that of the males.The crude and age-standardized incidence rates(ASIR)of esophageal cancer decreased in last 22 years.For male and female,crude incidence decreased by 2.22% and 3.56% per year and ASIR decreased by 5.18% and 6.56% per year.The mortality of esophageal cancer decreased in the last 22 years.Conclusion The incidence of esophageal cancer decreased in the last 22 years in Tianjin,but there is little overall improvement in survival.
