This comprehensive review explores the complex interplay between adhesion, metastasis, and inhibition in cancer progression. It highlights the pivotal role of adhesion molecules such as integrins and cadherins in cancer cell migration, invasion, and colonization of distant organs. The review discusses various inhibition strategies targeting these molecules, including integrin-blocking antibodies, small molecule inhibitors of focal adhesion kinase (FAK) and the Transforming Growth Factor β (TGF-β) pathway, and combination therapies. These approaches show promise in reducing cancer cell metastasis, with integrin inhibitors demonstrating a 75% reduction in metastatic events, particularly in advanced stages. The review also emphasizes the importance of prolonged treatment regimens and the identification of critical molecular regulators such as FAK, Src, β-catenin, and SMAD4 for further research and the development of targeted therapies. Additionally, it addresses the challenges and ethical considerations in implementing these treatments, including off-target effects, drug resistance, and the need for personalized medicine approaches. The review underscores the potential of advanced 3D culture systems and patient-derived xenografts in preclinical studies and the importance of clinical trials and biomarker-driven research for personalized treatment strategies.This comprehensive review explores the complex interplay between adhesion, metastasis, and inhibition in cancer progression.
