相对生存率为实际生存率和期望生存率之比,它表示由于生癌症引起的超额死亡数。本文推荐应用相对生存率来评价宫颈癌普查的效果。其资料来自江西靖安12年(1974～1985)宫颈癌人群普查结果。根据每二年一次普查的结果,头三轮普查5年相对生存率由72.9、85.6到99.6%,普查人群相对生存率接近标准人群,普查效果显著。后3轮由于普查人数、强度减少,相对生存率降至90.7%。5年相对生存率还与晚期病人的多少有关,可用于不同地区、国家和阶段相互对比。它比发病率、死亡率、减寿率和标化死亡率比等指标为好,可用作控制肿瘤效果考核的指标。
The relative survival rate is the ratio between the actual survival rate and the expected survival rate, and it represents the excess death caused by cancer. This article recommends the use of relative survival rates to evaluate the effectiveness of cervical cancer screening. The data from the census of cervical cancer in 12 years (1974-1985) in Jingan, Jiangxi Province. According to the results of a census every two years, the relative survival rate for the first three rounds of the census is 72.9, 85.6 to 99.6%, and the relative survival rate of the census population is close to that of the standard population. The census has a significant effect. In the last three rounds, the relative survival rate was reduced to 90.7% due to the decrease in the number and intensity of the census. The 5-year relative survival rate is also related to the number of late-stage patients and can be used to compare with each other in different regions, countries, and stages. It is better than indicators such as morbidity, mortality, life-threatening rate, and standardized mortality ratio, and can be used as an indicator to control the assessment of tumor effects.
