Special Issue Information

Dear Colleagues,

Liver metastases are a critical complication in colorectal cancer (CRC), significantly impacting patient survival and quality of life. Despite extensive research, challenges remain in understanding the underlying molecular mechanisms and improving the treatment outcomes for patients with CRC liver metastases. This Special Issue highlights the latest advancements in research, focusing on the biological processes, genetic alterations, and immune evasion strategies that drive the metastatic spread to the liver. Additionally, it discusses innovative diagnostic techniques, such as liquid biopsy and advanced imaging, which are crucial for early detection and monitoring disease progression. Therapeutic strategies, including surgical resection, liver-directed therapies, chemotherapy, targeted treatments, and immunotherapy, are examined for their clinical applicability and effectiveness. However, the Special Issue also underscores the major challenges, such as tumor heterogeneity, therapy resistance, and the need for personalized treatment approaches. The aim of this Special Issue is to provide a comprehensive review of the state-of-the-art research on CRC liver metastases, address current challenges, and propose future directions to optimize clinical management and improve patient outcomes.

Background: To overcome the limitations of conventional CRC (colorectal cancer) mouse models in replicating metastasis and enabling efficient therapeutic evaluation, we developed a novel implantation method using tissue adhesive to establish reproducible orthotopic and metastatic tumors. Conventional models using injection or suturing techniques often suffer from technical complexity, inconsistent tumor establishment, and limited metastatic reliability. Methods: We developed and validated a novel orthotopic and metastatic CRC model utilizing tissue adhesive for tumor transplantation. Uniform tumor fragments derived from bioluminescent HCT116/Luc xenografts were affixed to the cecum of nude mice. Tumor growth and metastasis were monitored through bioluminescence imaging and confirmed by the results of histological analysis of metastatic lesions. The model’s utility for therapeutic testing was evaluated using MK801, an NMDA receptor antagonist. Results: The biological-based model demonstrated rapid and reproducible tumor implantation (<5 min), consistent primary tumor growth, and robust metastasis to the liver and lungs. The biological-based approach achieved 80% tumor engraftment (4/5), with consistent metastasis to the liver and lungs in all mice, compared with lower and variable metastasis rates in injection (0%, 0/5) and suturing (20%, 1/5) methods. MK801 treatment significantly suppressed both primary tumor growth and metastasis, validating the model’s suitability for preclinical drug evaluation. Conclusions: By enabling rapid, reproducible, and spontaneous formation of metastatic lesions using a minimally invasive tissue adhesive technique, our model represents a significant methodological advancement that supports high-throughput therapeutic screening and bridges the gap between experimental modeling and clinical relevance in colorectal cancer research.
