A Two-Parameter Model for the Survival Curve of Treated Cancer Patients
治疗后癌症患者生存曲线的双参数模型
A two-parameter model for representing the survival curve of treated cancer patients is described. If PT is the proportion of the treated patients surviving to time T, and [Ptilde]T is the proportion of a normal population surviving to time T then the survival curve may be represented by: — PT/[Ptilde]T = c.e-loge c,e-βT , where c is the proportion cured and β is the asymptotic value as T approaches ∞ of the instantaneous risk of dying from cancer in the uncured group.
