Large-scale cancer genome-sequencing projects, such as the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA), have been instrumental in analyzing various cancer genomes, including prostate cancer, to explore genomic alterations and their diversity comprehensively (Nakagawa er al., 2015). These collaborations enable the sharing of data, resources, and expertise, which is essential for tackling the complexity and heterogeneity of cancer genomes. 5.3.2 Examples of global initiatives in prostate cancer genomics Several global initiatives have made significant contributions to prostate cancer genomics. For example, the ICGC and TCGA projects have focused on exome sequencing to analyze many types of cancer genomes, including prostate cancer, and have provided valuable insights into somatic mutations, copy number alterations, and other genomic features (Nakagawa er al., 2015). Additionally, multi-institutional efforts, such as the study on mCRPC that involved whole-exome and transcriptome sequencing of tumor biopsies from multiple institutions, have identified clinically actionable aberrations and new genomic alterations that could inform treatment strategies (Robinson et al., 2015). These examples highlight the importance of global collaborative efforts in advancing our understanding of prostate cancer genomics and improving patient outcomes. In conclusion, the future of whole-genome sequencing studies in prostate cancer lies in technological advancements, integrative approaches, and global collaborative efforts. By addressing current challenges and leveraging emerging technologies and international collaborations, researchers can continue to make significant strides in understanding and treating prostate cancer. 6 Concluding Remarks Whole-genome sequencing studies have significantly advanced our understanding of prostate cancer's genetic landscape. Key findings include the identification of novel driver mutations and pathways involved in disease progression. For instance, new putative driver genes such as NEAT1 and FOXA1 have been identified through noncoding mutations, and early events in cancer development like the loss of CHD1 and BRCA2 have been established. Additionally, frequent genomic alterations in genes such as AR, ETS, TP53, and PTEN have been observed, with specific mutations enriched in metastatic castration-resistant prostate cancer (mCRPC). Studies have also highlighted the genomic complexity and heterogeneity of prostate cancer across different ethnic populations, identifying unique genetic alterations in Chinese patients. Furthermore, the feasibility of using circulating tumor cells (CTCs) for genomic analysis has been demonstrated, providing a non-invasive method to study metastatic prostate cancer. The insights gained from WGS studies have profound clinical and research implications. Clinically, the identification of actionable genetic alterations can guide personalized treatment strategies. For example, alterations in DNA damage repair genes such as BRCA2 and ATM suggest potential responsiveness to PARP inhibitors. The discovery of novel therapeutic targets, such as those identified through computational chemogenomic analysis, opens new avenues for drug development and clinical trials. Research-wise, the enhanced understanding of prostate cancer's genomic landscape facilitates the development of precision medicine frameworks, enabling more accurate prognostic assessments and tailored therapeutic interventions. Additionally, the ability to perform genomic profiling using archival FFPE tissue samples broadens the scope of genomic studies, allowing for retrospective analyses and the inclusion of diverse patient cohorts. The advances in WGS have undeniably transformed prostate cancer research and treatment. However, several challenges remain. The heterogeneity of prostate cancer necessitates comprehensive genomic profiling to capture the full spectrum of genetic alterations. Future research should focus on integrating multi-omics data to provide a holistic view of the disease. Clinically, there is a need to establish standardized protocols for the implementation of genomic findings in routine practice, ensuring that patients benefit from the latest scientific advancements. Additionally, expanding genomic studies to include underrepresented populations will enhance the
