Inclusion of genetic alterations (mutations, translocations, etc.) and telomere modifications.

Main Results:

Nucleic acid biomarkers provide a unique diagnostic and prognostic approach.
Epigenetic and genetic alterations are key molecular events in cancer transformation.
Telomere dynamics are significant in cancer progression.

Conclusions:

Nucleic acid biomarkers are valuable tools for clinicians in urologic oncology.
These biomarkers can improve disease diagnosis, risk stratification, and treatment decisions.
Further research into these molecular markers can enhance patient management and outcomes.
