However, in patients with BRAF-mutated melanomas, those who received BRAF inhibitors exhibited improved survival outcomes in advanced disease stages (p = 0.0025). Our study indicates that BRAF-mutated melanoma patients with distant metastases receiving BRAF inhibitors have significantly improved survival compared to those not receiving targeted therapy, supporting the clinical benefit of BRAF inhibitor use in appropriately selected patients.

This study establishes a high-performance inflammatory pathway-based prognostic model for melanoma and demonstrates that driver mutation subtypes differentially shape the immune microenvironment landscape. CCNE1 functions as a key oncogenic immune regulator whose modulation of antigen presentation and immune checkpoint expression is contingent on mutational context, most prominently in NF1-mutant tumors, underscoring the value of mutation-informed personalized immunotherapy strategies in melanoma.

Molecular-risk stratification and integrated modeling identify clinically meaningful prognostic groups in CRLM. These findings support incorporation of genomic profiling into precision surgical and transplant evaluation, while emphasizing the need for prospective validation.

The SWOG S1801 trial demonstrated better event-free survival with perioperative pembrolizumab compared to adjuvant therapy alone. Lastly, the phase III NADINA trial showed that neoadjuvant ipilimumab plus nivolumab followed by response-adapted adjuvant therapy significantly improves outcomes. Biomarkers such as PD-L1, IFN-γ signature, tumor mutational burden and imaging (PET scan) appear promising to predict response, but none have been sufficiently validated for routine clinical practice.

While significant progress has been made, the integration of melanoma biomarkers into routine clinical practice remains limited. This review summarizes current advancements in melanoma biomarkers, including traditional serum and immunohistochemical markers, as well as developments in molecular, genetic, circulating, and predictive biomarker approaches.

Trametinib monotherapy offers limited CB in patients harboring NRAS-mutant malignancies. Future research should further explore the biological and clinical significance of specific NRAS codon mutations to identify biomarkers and optimize treatment approaches.

This study demonstrated that dynamic changes in plasma RAS mutation status may occur during disease progression in patients with mCRC, potentially reflecting tumor clonal evolution. The observed survival advantage in patients with RAS mutation clearance suggests potential prognostic relevance. Reassessment of RAS status using liquid biopsy at disease progression may provide clinically relevant information; however, these findings should be considered exploratory and require prospective validation in larger cohorts.

Radiotherapy significantly contributes to long-term severe anastomotic complications. Male patients exhibiting low BMI and diminished PFS at inferior tumor margins demonstrate the highest risk profile.

Evidence is emerging to position ctDNA as a dynamic biomarker that complements conventional melanoma staging by capturing real-time tumor burden, treatment response, and residual disease. Its clinical utility is most robust in high-risk and advanced melanoma, where ctDNA reliably informs prognosis, molecular residual disease, and early relapse, while sensitivity constraints limit its current role in early-stage disease with low tumor burden.

Anti-CD69 monoclonal antibody treatment was associated with reduced generation of granulocyte-macrophage progenitor cells, prolonged survival, and decreased Treg accumulation in the BME. Our findings suggest that CD69 may serve as a biomarker of BME immunological dysfunction in CMML.
