Summary of article contents:

Introduction

Colorectal cancer (CRC) ranks as one of the leading causes of cancer-related deaths worldwide, underscoring the importance of early diagnosis and accurate staging for improved patient outcomes. Metabolomics serves as a promising tool to identify metabolite profile changes associated with different cancer stages, paving the way for non-invasive diagnostic methodologies. This review aims to systematically explore metabolomic alterations in human biological samples throughout the stages of CRC, pinpointing key metabolic pathways involved in cancer progression and potential biomarkers for prognosis.

Distinct Metabolite Changes in CRC Progression

A notable finding from the systematic review is the identification of metabolites related to redox status, energy metabolism, and amino acid metabolism that exhibit significant changes during CRC progression. Notably, metabolites such as glycine were found to have increased levels in late-stage cancer, indicating a potential role in tumorigenesis. For instance, studies revealed that glutathione and branched-chain amino acids (leucine and isoleucine) were consistently upregulated across various stages of CRC, highlighting the metabolic reprogramming that supports cancer growth. Conversely, certain metabolites, such as butyrate and glucose, were downregulated, likely reflecting alterations in metabolic pathways essential for cellular function in cancer development.

Conclusion

In conclusion, this systematic review illustrates that metabolic changes associated with CRC can be effectively identified through metabolomics, revealing crucial insights into the progression of the disease. While some metabolites showed consistent upregulation or downregulation across various studies, the differences noted in metabolite profiles suggest that multiple factors—such as study population, sample types, and analytical approaches—may influence the findings. Given the limited published data on metabolomics in CRC stages, further research is warranted to standardize methodologies and enhance understanding of CRC progression, potentially leading to the identification of novel biomarkers for diagnosis and treatment strategies.
