This narrative review synthesizes existing literature to evaluate the effectiveness of prehabilitation interventions in improving outcomes for GI cancer patients undergoing surgery. Drawing on a comprehensive analysis of available evidence, the review examines the integration of nutritional, physical, and psychosocial interventions and explores the implications for clinical practice and future research. The review highlights the importance of standardized protocols and interdisciplinary collaboration in optimizing prehabilitation programs for GI cancer patients. It identifies gaps in current research, particularly regarding the synergistic effects of integrating various intervention modalities and the role of innovative strategies such as immunonutrition. Moreover, the review underscores the need for larger studies to assess the effectiveness of multimodal prehabilitation approaches and establish standardized outcome measures. In conclusion, despite advancements in understanding the importance of prehabilitation, significant gaps persist in the literature, warranting further research to refine prehabilitation protocols and improve perioperative outcomes for GI cancer patients.

These technologies enable a deeper understanding of cancer and provide personalized treatment strategies. However, challenges such as standardization and appropriate methods for funneling complex information into clinical consequences remain. The tumor microenvironment (TME) is a complex system containing cancer cells, immune cells, stromal cells, and secreted molecules. To overcome these challenges, researchers can establish standardized protocols for data collection, analysis, and interpretation. Collaborations and data sharing among research groups and institutions can create a comprehensive and standardized multi-omics database, facilitating cross-validation and comparison of results. Multi-omics profiling enables in-depth characterization of diversified tumor types and better reveal their function in cancer immune escape.
