Abstract:
Androgen deprivation therapy (ADT) is the cornerstone treatment for advanced prostate cancer. Despite frequent responses, the majority of metastatic tumors will progress to castration-resistant prostate cancer. Numerous molecular and genetic perturbations have been described in castration-resistant prostate cancer, which are attributable for gain-of-function changes in the androgen receptor, allowing for cell survival and proliferation with castrate levels of testosterone. The utility of these somatic perturbations, which are selected for in the tumor after ADT, for prognostication of response and response duration in metastatic prostate cancer, is problematic. Here, we discuss recent studies that describe germline polymorphisms that determine the response to ADT. Coding and noncoding germline polymorphisms in genes involved in the androgen pathway affect the response to ADT. These polymorphisms require further study and validation. However, they have the potential to be useful for prognosticating the response to ADT, designing clinical trials for patients who have poor germline prognostic features and designing novel therapies targeted against genes that influence the response to ADT.
Insights
Germline polymorphisms, or inherited genetic variations, can predict how well patients with advanced prostate cancer respond to androgen deprivation therapy (ADT). These variations offer potential for personalized treatment strategies and novel drug development.
Area of Science:
- Oncology
- Genetics
- Urology
Background:
- Androgen deprivation therapy (ADT) is a primary treatment for advanced prostate cancer.
- Most metastatic prostate tumors eventually develop resistance to ADT, progressing to castration-resistant prostate cancer.
- Genetic changes in tumors drive resistance by altering androgen receptor function.
Purpose of the Study:
- To explore the role of germline polymorphisms in predicting response to ADT.
- To evaluate the potential of these genetic variations for patient prognostication and treatment design.
Main Methods:
- Review of recent studies investigating germline polymorphisms.
- Analysis of coding and noncoding polymorphisms in androgen pathway genes.
Main Results:
- Germline polymorphisms in androgen pathway genes influence patient response to ADT.
- Somatic genetic changes in tumors after ADT are less reliable for prognostication.
Conclusions:
- Germline polymorphisms can serve as valuable prognostic markers for ADT response in prostate cancer.
- Further research and validation are needed for clinical application.
- These findings may guide clinical trial design and the development of targeted therapies.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
