摘要:

本文提出了一个计算转移瘤的时间发展、大小分布和承载能力的数学模型。该模型用于理论上研究抗癌疗法,如手术和化学治疗(细胞毒性或抗血管生成),单药治疗或联合治疗。手术对转移性集落的大小分布的影响的定量推导。对于全身性治疗,重点放在孤立病变和转移人群的治疗之间的差异。联合治疗,特别是药物给药顺序的问题。理论上的最佳时间表的推导表明,一个节拍的管理计划(定义为在整个治疗周期中的给药量的药物扩散的连续管理)的一个经典的最大耐受剂量方案(其中剂量是作为几个集中管理在周期开始),在生物体中的总转移负荷的优效性。

英文摘要:

A mathematical model for time development of metastases and their distribution in size and carrying capacity is presented. The model is used to theoretically investigate anti-cancer therapies such as surgery and chemical treatments (cytotoxic or anti-angiogenic), in monotherapy or in combination. Quantification of the effect of surgery on the size distribution of metastatic colonies is derived. For systemic therapies, emphasis is placed on the differences between the treatment of an isolated lesion and a population of metastases. Combination therapy is addressed, in particular the problem of the drugs administration sequence. Theoretical optimal schedules are derived that show the superiority of a metronomic administration scheme (defined as a continuous administration of a given amount of drug spread during the whole therapeutic cycle) on a classical Maximum Tolerated Dose scheme (where the dose is given as a few concentrated administrations at the beginning of the cycle), for the total metastatic burden in the organism.
