Prostate cancer is a health problem in many Countries worldwide. Understanding the essential function of androgens in the prostate physiology led to the development of hormonal blockade as a therapeutic option in advanced disease, with limited response with time and development of resistance. In this stage, where castration resistant prostate cancer (CRPC) is defined, it is associated with poor prognosis because survival varies between 18 and 24 months. Even with castration levels, tumors are dependent on the functional androgen receptor (AR). In this paper, we analyze pretreatment clinical parameters such as prognostic or progression-predictive biomarkers, castration resistance mechanisms, the development of new technologies for the use of the so called liquid biopsies from biological ayufluids and the identification of circulating tumor cells as CRPC response and progression biomarkers. Currently ongoing clinical trials are partially oriented to the search of new prognostic and predictive biomarkers, that will enable to open up precision medicine and so to improve oncological patient's quality of life with it.

Background: Metastatic prostate cancer (PCa) has much lower survival and ultimately develops castration resistance, which expects novel targets and therapeutic approaches. As a result of iron-dependent lipid peroxidation, ferroptosis triggers programmed cell death and has been associated with castration-resistant prostate cancer (CRPC).
Subjects: To better understand how ferroptosis can be used to treat CRPC, we reviewed the following: First, ferroptosis mechanisms and characteristics.

Background And Objective: Castration-resistant prostate cancer (CRPC) is caused by resistance to androgen deprivation treatment and leads to the death of patients and there is almost no chance of survival. Therefore, finding a cure to overcome CRPC is challenging and important, but discovering a new drug is very time-consuming and expensive. To overcome these problems, we used Drug repositioning (drug repurposing) strategy in this study.

Purpose: No currently available phase III trial compared docetaxel vs. androgen receptor pathway inhibitors (ARPI) regarding cancer-control outcomes in metastatic hormone-sensitive prostate cancer (mHSPC). Moreover, few is known about the effect of sequential therapies in mHSPC and subsequent metastatic castration resistant prostate cancer (mCRPC).

Neoadjuvant therapy (NAT) has been studied in clinically localized prostate cancer (PCa) to improve the outcomes from radical prostatectomy (RP) by 'debulking' of high-risk PCa; however, using androgen deprivation therapy (ADT) at this point risks castration resistant PCa (CRPC) clonal proliferation. Our goal is to identify alternative NAT that reduce hormone sensitive PCa (HSPC) without affecting androgen receptor (AR) transcriptional activity. PCa is associated with increased expression and activation of the epidermal growth factor receptor (EGFR) family, including HER2 and ErbB3.

Immunotherapy with checkpoint inhibitors produced significant clinical responses in a subset of cancer patients who were resistant to prior therapies. However, Castration-resistant prostate cancer (CRPC) is seriously lack of T cell infiltration, which greatly limits the clinical application of immunotherapy, but the mechanism is unclear. In the present study, in silico analyses and experimental data show that HnRNP L was significantly negatively correlated with CD4+ and CD8+ T cells infiltration in patients; besides, we found deficiency of HnRNP L recruites CD4+ and CD8+ T cells infiltration and impairs tumorigenesis.
