本文讨论了独立死因校正后生存率的计算方法，提出了一种最大似然法，并用瑞士日内瓦结肠癌患者的生存率作了说明。如果人口的预期寿命各不相同，则目前用于进行此类计算的方法在估计净存活率时会出现各种偏差。建议的最大似然法将消除这些偏差，使相关的协变量影响生存的调整。常规使用这些方法将能够更好地比较人口内和人口之间的生存情况。
The methods of calculation of survival corrected for independent cause of death are discussed, and a maximum likelihood method is proposed and illustrated by survival of colon cancer patients in Geneva (Switzerland). The methods which are at present favoured for doing such calculations are subject to various biases when estimating net survival if the populations are heterogeneous for life expectancy. The proposed maximum likelihood approach would eliminate these biases by enabling relevant adjustment for covariates which influence survival. The routine use of such methods would permit better comparison of survival within and between populations.
