In the latter two groups, successful outcomes may not be achieved due to the development of drug-resistant cells in the tumor environment during treatment. To overcome this challenge, a secondary drug can be used to control the population of drugresistant cells, potentially leading to a longer period of disease inhibition. This paper proposes using a combination of Docetaxel and Abiraterone in some polytherapy methods to control both the overall cancer cell population and the drug-resistant subpopulation. To investigate the competition and evolution of mCRPC cancer phenotypes, as in previous studies, the Evolutionary Game Theory (EGT) has been used as a mathematical modeling of evolutionary biology concepts.  \nIntroduction  \nProstate cancer is a common cancer among men and the second-leading cause of cancer death in men [ 1] . Early diagnosis is possible through Prostate-Specific Antigen (PSA) testing, improving men’s life expectancy [2] . High levels of androgens are associated with the development and progression of prostate cancer in men. CYP17A, AR, SRD5A2, HSD3B1, and HSD3B2 genes play a special role in androgen metabolism and cell proliferation in the prostate [3] . Androgen deprivation therapy (ADT) is used to slow the growth of prostate cancer by reducing the androgen concentration in blood or preventing androgens from affecting the prostate cancer cells [4] . The CYP17A enzyme is involved in androgen synthesis and the pathogenesis of prostate cancer. Inhibitors of CYP17A, such as abiraterone, stop the production of androgens by prostate cancer cells by inhibiting the CYP17A enzyme in the prostate [5, 6] .  \nMetastatic castration-resistant prostate cancer can still grow and spread despite reduced testosterone production [7, 8] . There are three phenotypes of mCRPC: T+, TP, and T− . T+ cells require testosterone to survive and multiply, while TP cells produce the necessary testosterone through rearrangement of CYP17A. T− cells, which are resistant, can multiply without relying on testosterone [9, 10] .  \nOne common treatment for mCRPC is the use of maximum tolerated dose (MTD) treatment, in which medications are used at their highest tolerable dose as long as there are no side effects. However, the MTD treatment approach can lead to the elimination of sensitive phenotypes and the competitive release of the resistant population","cbCaiivBExHLZIte","https://ap.wps.com/l/cbCaiivBExHLZIte","pdf",1091355,"English","# Abstract\n# Introduction","[{\"question\":\"How are mCRPC patients grouped based on response to abiraterone?\",\"answer\":\"They are divided into best responder, responder, and non-responder groups according to treatment response to abiraterone.\"},{\"question\":\"Why can treatment fail in the responder and non-responder groups?\",\"answer\":\"Because drug-resistant cells can develop in the tumor environment during treatment, preventing successful outcomes.\"},{\"question\":\"What modeling framework is used to study competition and evolution of mCRPC phenotypes?\",\"answer\":\"Evolutionary Game Theory (EGT) is used as a mathematical modeling approach to represent evolutionary biology concepts and phenotype competition.\"}]","Abiraterone-Docetaxel scheduling for metastatic castration-resistant prostate cancer based on evolutionary dynamics | PDF",1790256260,23]
