Epidemiological charactristics of cancer in Zhoushan City / 预防医学

ABSTRACT

Objective@#To investigate epidemiological characteristics of cancers in Zhoushan City in 2018, so as to provide the evidence for the formulation of cancer control strategies.@*Methods@#The cancer data in Zhoushan City in 2018 were captured from Zhejiang Provincial Information Management System for Chronic Disease Surveillance. The gender- and age-specific incidence of cancers was descriptively analyzed. The cancer incidence was standardized to the data of the Sixth National Population Census in China in 2010 ( Chinese standard population ) and Segi's world standard population.@*Results@#The crude incidence rate, age-standardized incidence rate by Chinese standard population ( ASR China ), and age-standardized incidence rate by world standard population ( ASR world ) of cancers were 468.65/105, 300.12/105 and 232.79/105 in Zhoushan City in 2018, and the cumulative cancer incidence rate was 26.91% among residents at ages of 0 to 74 years, while the truncated-age cancer incidence rate was 431.90/105 among residents at ages of 35 to 64 years. The crude incidence rate, ASR China, and ASR world of cancers were 473.00/105, 285.67/105 and 229.03/105 in men, and 464.43/105, 317.66/105 and 241.30/105 in women in Zhoushan City in 2018, respectively. In addition, the mean age of new cases with cancers in 2018 was ( 61.34±13.19 ) years in Zhoushan City in 2018, and the highest crude cancer incidence was seen in residents at ages of 70 to 74 years ( 1 327.50/105 ). The crude cancer incidence rate was higher in new female cases at ages of 25 to 54 years than in new male cases, and the crude cancer incidence rate was higher in new male cases at ages of 60 to 84 years than in new female cases ( P<0.05 ). The 10 most common cancers included lung cancer, female breast cancer, thyroid cancer, gastric cancer, colorectal cancer, liver cancer, cervical cancer, prostatic cancer, pancreatic cancer and bladder cancer, which accounted for 80.20% of all cancers in Zhoushan City in 2018.@*Conclusions@#High cancer incidence was found in Zhoushan City in 2018, and elderly populations are at high risk of developing cancers. The management of lung cancer, female breast cancer, thyroid cancer, gastric cancer and colorectal cancer should be given a high priority.
