In this paper we present a new version of a mathematical model of Elishmereni et al. describing androgen deprivation therapy (ADT) for hormone sensitive prostate cancer patients (HSPC). We first focus on the detail description of the model, and then we present mathematical analysis of the proposed model, starting from the simplified model without resistance and ending on the full model with two resistance mechanisms present. We make a step towards personalization proposing an underlying tumor growth law base on a cohort of patients from Mayo hospital. We conclude that the model is able to reflect reality, that is in clinical scenarios the level of testosterone in HSPC patients inevitably rises leading to the failure of ADT.
在本文中,我们提出了一种新的数学模型版本,用于描述伊莱舍梅里尼等人描述的去势治疗(ADT)对激素敏感前列腺癌患者(HSPC)的作用。我们首先专注于模型的详细描述,然后对所提出的模型进行数学分析,从没有抵抗机制的简化模型开始,最后得出包含两种抵抗机制的完整模型。我们通过基于梅奥医院的患者队列提出了一种潜在的肿瘤生长规律,朝着个性化治疗迈出了一步。我们的结论是,该模型能够反映现实,即在临床情况下,HSPC 患者的睾丸激素水平不可避免地上升,导致 ADT 失败。
