Abstract:
Metastatic castration-resistant prostate cancer (CRPC) is associated with substantial clinical, pathologic, and molecular heterogeneity. Most tumors remain driven by androgen receptor (AR) signaling, which has clinical implications for patient selection for AR-directed approaches. However, histologic and clinical resistance phenotypes can emerge after AR inhibition, in which the tumors become less dependent on the AR. In this review, we discuss prostate cancer variants including neuroendocrine (NEPC) and aggressive variant (AVPC) prostate cancers and their clinical implications. Improvements in the understanding of the biologic mechanisms and molecular features underlying prostate cancer variants may help prognostication and facilitate the development of novel therapeutic approaches for subclasses of patient with CRPC.
Insights
Metastatic castration-resistant prostate cancer (CRPC) shows significant heterogeneity. Understanding variants like neuroendocrine prostate cancer (NEPC) and aggressive variant prostate cancer (AVPC) is crucial for developing targeted therapies.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Metastatic castration-resistant prostate cancer (CRPC) presents considerable heterogeneity.
- Androgen receptor (AR) signaling drives most CRPC, guiding treatment selection.
- Resistance to AR-directed therapies can lead to tumor dependence on AR diminishing.
Purpose of the Study:
- To review prostate cancer variants, including neuroendocrine prostate cancer (NEPC) and aggressive variant prostate cancer (AVPC).
- To discuss the clinical implications of these prostate cancer variants.
- To highlight the importance of understanding biologic mechanisms and molecular features for improved prognostication and novel therapeutics.
Main Methods:
- Literature review of prostate cancer variants.
- Analysis of clinical, pathologic, and molecular heterogeneity in CRPC.
- Discussion of resistance phenotypes and AR signaling.
Main Results:
- CRPC exhibits significant heterogeneity.
- AR signaling remains a key driver, but resistance mechanisms emerge.
- NEPC and AVPC represent distinct aggressive subtypes with unique clinical implications.
Conclusions:
- Understanding the molecular features of prostate cancer variants is essential for prognostication.
- Novel therapeutic strategies for CRPC subclasses can be developed by studying these variants.
- Further research into the biology of NEPC and AVPC is critical for advancing treatment.
