Castration-resistant prostate cancer was subjected to a paradigm switch from hormone resistance to androgen deprivation therapy resistance during the last decade. Indeed, new therapeutics targeting the androgen receptor showed clinical efficacy in patients with progressive disease under castration. Thus, it is a proof that the AR remains a dominant driver of oncogenesis in earlier-called hormone resistant prostate cancer. This review summarizes the molecular mechanisms involved in castration-resistant prostate cancer.

Androgen deprivation therapy (ADT) is the primary treatment strategy for prostate cancer. However, despite an initially favorable response, tumors inevitably progress to castration-resistant prostate cancer (CRPC). Therefore, the exploration of new therapeutic approaches targeting CRPC has become imperative.

Prostate cancer (PCa) is the second most common cancer among men worldwide. The main screening tool remains the prostate-specific antigen (PSA), which shows significant limitations, including poor sensitivity/specificity. Therefore, establishing accurate non-invasive diagnostic biomarkers remains an unmet clinical need in PCa.

Background/aim: Although multiple treatments are available for metastatic castration-resistant prostate cancer, data to determine the optimal treatment sequence are limited. This study aimed to investigate the current status of drug therapy for castration-resistant prostate cancer and clarify the sequential treatment in actual clinical practice.
Patients And Methods: This retrospective study included 425 patients diagnosed with castration-resistant prostate cancer at Showa University Hospital and affiliated hospitals between January 2014 and December 2021, who were treated with any of the following four drugs: novel androgen receptor signal inhibitors (abiraterone acetate and enzalutamide) and anticancer drugs (docetaxel and cabazitaxel).

Rationale And Objectives: Recently, the Response Evaluation Using PSMA PET/CT in Patients with Metastatic Castration-Resistant Prostate Cancer (RECIP 1.0) was proposed to better evaluate treatment response in prostate cancer patients using PET/CT with prostate-specific membrane antigen (PSMA) than more traditional approaches like metabolic PET evaluation response criteria in solid tumor (PERCIST 1.0).

Treatment for castration-resistant prostate cancer (CRPC) primarily involves the suppression of androgen receptor (AR) activity using androgen receptor signaling inhibitors (ARSIs). While ARSIs have extended patient survival, resistance inevitably develops. Mechanisms of resistance include genomic aberrations at the AR locus that reactivate AR signaling, or lineage plasticity that drives emergence of AR-independent phenotypes.
