[Purpose] The survival rate of breast cancer cases in the whole population from 1972 to 2019 in Qidong was analyzed to provide a basis for prognosis assessment and prevention. [Methods] Observed survival rate (OSR), relative survival rate(RSR), age-adjusted relative survival (ARS) and average annual change percentage (AAPC) were calculated. ARIMA model was used to predict the trend of breast cancer survival rate. [Results] The 5-year RSR increased from 57.30% in 1972-1977 to 89.01% in 2014-2019, and the uptrend of RSR in the eight periods was statistically significant ( χ2= 534.03, P <0.001). The 5-year ARS increased from 48.12% in 1972-1977 to 85.64% in 2014-2019. The AAPC of 5-ARS was 1.85% (t =10.113, P<0.001), the uptrend were statistically significant . For males, the 5-RSR in 1972-2019 was 85.22%, and for females was 74.51%,. For females, the 5-year RSR increased from 56.44% in 1972-1977 to 88.93% in 2014-2019, the 5-year ARS increased from 46.14% in 1972-1977 to 85.23% in 2014-2019, the AAPC of 5-RSR was 1.29% (t =13.087, P<0.001), and the AAPC of 5-ARS was 1.90% (t =10.369, P<0.001), the uptrend were statistically significant . The 5-year RSR for the age groups of 25-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 66.91%, 74.69%, 76.97%, 75.52%, 73.44% and 66.40%, respectively. The AAPC of 5-RSR aged 25-34 years was 1.02% (t=3.816, P=0.009), aged 35-44 years was 1.03% (t = 4.936, P=0.003), aged 45-54 years was 1.23% (t =5.826, P=0.001), aged 55-64 years was 1.86% (t =5.997, P=0.001), aged 65-74 years was 2.13% (t =10.245, P<0.001), and aged over 75 years was 1.44% (t = 6.405, P=0.001), respectively. The uptrend was statistically significant. After ARIMA modeling for survival trend prediction, 5-RSR and 5-ARS for breast cancer ascended to 94.73% and 93.40%, respectively, by 2023. [Conclusion] The overall survival rate of registered breast cancer cases in Qidong City has been greatly improved, but there is still a proportion for improvement, more attention should be paid to the prevention and treatment of breast cancer. |
