| Abstract: [Purpose] To analyze the incidence and mortality, trends, and survival of gallbladder cancer in Nantong from 2013 to 2017. [Methods] The gallbladder cancer incidence and mortality data from 2013 to 2017 were collected from Nantong cancer registries. The incidence and mortality were calculated by gender, age and urban and rural areas. Joinpoint software was used to analyze the incidence and mortality trends of gallbladder cancer. The observed survival rate and relative survival rate were calculated by using life table method and Ederer II method respectively. [Results] From 2013 to 2017, the gallbladder cancer incidence and mortality rates were 6.36/105 and 4.91/105 , respectively; the age-standardized incidence and mortality rates by Chinese standard population in 2000 (ASIRC,ASMRC) were 2.62/105 and 1.94/105 , respectively. The crude incidence and mortality , and ASMRC showed an increasing trend (P<0.05). The ASIRC for male and female was 2.43/105 and 2.83/105 respectively; The ASMRC for male and female was 1.74/105 and 2.16/105, respectively, with ASIRC and ASMRC in female being higher than those in male. The average age of onset is 70.33 years old, and the median age of onset is 72 years old. The ASIRC in urban and rural areas was 2.40/105 and 2.69/105, respectively, and the ASMRC was 1.61/105 and 2.05/105, respectively. ASIRC and ASMRC in Rural areas were higher than those in urban areas. The crude incidence and mortality rate and ASMRC of gallbladder cancer in rural areas showed an increasing trend (P<0.05). The 5-year observed survival rate was 12.90%, and the 5-year relative survival rate was 14.47%. Both the 5-year observed survival rate and relative survival rate showed an increasing trend (P<0.05).[Conclusion]It is suggested that targeted prevention and control measures should be taken to strengthen the comprehensive prevention and control capacity of gallbladder cancer in Nantong, focus on rural areas and middle-aged and elderly women, reduce the incidence rate and mortality of gallbladder cancer in Nantong, and improve the survival rate of patients. |
