AACR 2025 | Integrating tissue and liquid biopsies in solid tumor management

Paolo Marchetti, MD, PhD, IDI-IRCCS, Rome, Italy, discusses the potential of combined biopsy approaches in advanced tumor management, highlighting their value in cases with multiple metastases or high tumor fraction, as well as their ability to target specific molecular pathways. The ROME trial (NCT04712864) provides strong evidence for the enhanced precision of cancer diagnostics and treatment outcomes achieved through integrating tissue and liquid biopsies. This interview took place at American Association for Cancer Research (AACR) Annual Meeting 2025 in Chicago, IL.

Combined biopsy data can be integrated with additional omics layers through several new approaches. A multimodal data fusion allows the integration of radiomics, proteomics, transcriptomics, and metabolomics with the genomic data from dual biopsies, providing holistic tumor characterization. All intelligence-driven frameworks can integrate these different data types, capturing the longitudinal evolution of biomarkers and complex tumor biology...

Combined biopsy data can be integrated with additional omics layers through several new approaches. A multimodal data fusion allows the integration of radiomics, proteomics, transcriptomics, and metabolomics with the genomic data from dual biopsies, providing holistic tumor characterization. All intelligence-driven frameworks can integrate these different data types, capturing the longitudinal evolution of biomarkers and complex tumor biology. Future evolutions may include the integration of immunomics and spatial transcriptomics with conventional multiomics data to comprehensively characterize the tumor microenvironment. Advanced machine learning techniques excel at extracting meaningful patterns across integrated omics data sets while preserving biologically relevant signals. This allows for more precise therapeutic targeting based on comprehensive molecular profiles. Liquid biopsy combined with artificial intelligence algorithms could identify cancer-specific molecular signatures with remarkable sensitivity and enable dynamic monitoring of tumor evolution and therapeutic response in real-time.
