Objective To describe the epidemiological characteristics of pancreatic cancer incidence in Qidong between 1972 and 2021, and to provide guidelines for prevention and control measures and strategies.
Methods The cancer registry data was collected and analyzed on pancreatic cancer incidence during 1972—2021 in Qidong by sex, age and time. Crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), annual percent change (APC) and average annual change percentage (AAPC) were calculated by Joinpoint software. Age-period-cohort model used to analyze the influence of age, period and birth cohort on the changes in the incidence trend of pancreatic cancer patients.
Results From 1972 to 2021, there were 5 674 patients from pancreatic cancer in Qidong, accounting for 3.85% of all cancer new cases, with a incidence rate of 10.12/105, ASRC of 3.66/105, ASRW of 6.09/105. The truncated incidence of 35~64 years old was 8.05/105, the cumulative incidence rate between the ages of 0 and 74 years old was 0.73%, the cumulative risk was 0.73%. There were 3 122 patients for male, the CR, ASRC, and the ASRW were 11.29/105, 4.47/105 and 7.41/105. the patients for female were 2 552, and the CR, ASRC, and the ASRW were 8.97/105, 2.93/105 and 4.93/105,respectively. the CR of the 0~44, 45~54, 55~64, 65~74, 75~ year-old were 0.63/105, 6.41/105, 19.06/105, 43.46/105, 68.24/105. The AAPC of age-groups were 1.30% (95%CI:-0.60%~3.23%), 1.12% (95%CI:0.10%~2.14%), 0.36% (95%CI:-0.70%~1.43%), 0.86% (95%CI:-0.16%~1.88%), 2.96% (95%CI:1.54%~4.41%). The increasing trend of incidence rate in 45~54 year-old amd 75~ year-old were statistically significant (P<0.05). From 1972 to 2021, the AAPC of CR, ASRC, and ASRW in the pancreatic cancer were 4.40% (95%CI:3.98%~4.81%), 0.95%(95%CI:0.57%~1.33%), 1.21(95%CI: 0.82%~1.59%). The increasing trend of incidence rates were statistically significant (P<0.05). The age-period-cohort model shows that the risk of pancreatic cancer increases with age, and the greater risk of pancreatic cancer with the later the person is born. (P<0.05).
Conclusions The incidence of the pancreatic cancer has presented a rising trend in the past fifty years, The health administrative department should formulate prevention and control measures to reduce the burden of pancreatic cancer. |
