Vitamin A is a crucial nutrient renowned for its role in visual health and cellular regulation. Its derivatives influence cell differentiation, proliferation, and tissue homeostasis, making them significant in cancer research due to their effects on both normal and tumour cells. This review explores the intricate relationship between vitamin A metabolism and the extracellular matrix (ECM) in cancer. The ECM profoundly affects tumour behaviour, including proliferation, invasion, and metastasis. Alterations in the ECM can facilitate tumour progression, and vitamin A derivatives have shown potential in modulating these changes. Through transcriptional regulation, vitamin A impacts ECM components and matrix metalloproteinases, influencing tumour dynamics. The review highlights the potential of vitamin A and its derivatives as adjunctive agents in cancer therapy. Despite promising laboratory findings, their clinical application remains limited due to challenges in translating these effects into therapeutic outcomes. Future research should focus on the modulation of retinol metabolism within tumours and the development of targeted therapies to enhance treatment efficacy and improve patient prognosis.
