Introduction: from the discovery of the Philadelphia chromosome to the advent of next-generation sequencing (NGS), cancer genomics has transformed the molecular understanding of cancer. This article presents a narrative review with historical reconstruction, key milestones, major barriers, and future perspectives in tumor genomics.
Methods: a systematic search was conducted in three international databases; out of 137 records, 29 articles were selected for full review, along with various primary historical sources.
Results: this work examines technological evolution, clinical milestones, and the impact of genomics on oncology practice. In addition, some current challenges and future perspectives for its implementation were discussed.
Discussion: despite reviewing a time span of just over half a century, the research team acknowledges that these concepts are still constantly evolving and that overcoming current genomic barriers will likely be the next major milestone. Oncogenomics may be entering a golden era; its clinical implementation is increasingly becoming a reality and a standard.
Conclusion: in the era of massive data analysis, artificial intelligence, and robust global collaboration consortia, critically looking back at the past can also strengthen future steps. Cancer is now understood as a disease of the genome; however, it remains necessary to continue overcoming theoretical, scientific, implementation, accessibility, and cross-disciplinary obstacles.
