The integration of radiogenomics into personalized therapy has shown promising advancements in understanding and treating various cancers. A notable study characterized the proteogenomic landscape of 242 high-grade serous ovarian cancers (HGSOCs), revealing a 64-protein signature that predicts chemo-refractoriness with high specificity. This signature was validated across two independent cohorts, highlighting the significant association between the absence of Ch17 loss of heterozygosity and resistance to platinum-based therapies (ref: Chowdhury doi.org/10.1016/j.cell.2023.07.004/). In the realm of breast cancer, circulating tumor DNA (ctDNA) was examined for its association with residual cancer burden after neoadjuvant chemotherapy in triple-negative breast cancer (TNBC). The study identified responders and matched non-responders, demonstrating the potential of ctDNA as a biomarker for treatment efficacy (ref: Parsons doi.org/10.1016/j.annonc.2023.08.004/). Furthermore, the efficacy of nivolumab combined with ipilimumab in advanced salivary gland cancer was assessed, showing modest response rates, particularly in cohort 2, which included other salivary gland cancers (ref: Vos doi.org/10.1038/s41591-023-02518-x/). These findings underscore the importance of personalized approaches in cancer therapy, utilizing genomic and proteomic data to tailor treatments effectively. In addition to these findings, the study of anlotinib combined with icotinib for EGFR-mutated advanced non-small cell lung cancer (NSCLC) revealed promising results, particularly in patients with concurrent mutations, achieving a median progression-free survival of 15.6 months (ref: Zhang doi.org/10.1186/s12943-023-01823-w/).
