TDSEVs are known to orchestrate the invasion-metastasis cascade via diverse pathways. Regulation of early metastasis processes, pre-metastatic niche formation, immune system regulation, angiogenesis initiation, extracellular matrix (ECM) remodeling, immune modulation, and epithelial-mesenchymal transition (EMT) are among the pathways regulated by TDSEVs. MicroRNAs (miRs) carried within TDSEVs play a pivotal role as a double-edged sword and can either promote metastasis or inhibit cancer progression. TDSEVs can serve as excellent markers for early detection of tumors, and tumor metastases. From a therapeutic point of view, the risk of cancer metastasis may be reduced by limiting the production ofTDSEVs from tumor cells. On the other hand, TDSEVs represent a promising approach for in vivo delivery of therapeutic cargo to tumor cells. The present review article discusses the recent developmentsand the current views ofTDSEVs in the field of cancer research and clinical applications.  \nKeywords Biomarkers, Cancer, Epithelial-mesenchymal transition, Metastasis, MicroRNA, Oncogenic transformation, Tumor-derived small extracellular vesicles, Tumor microenvironment  \n†Chi Zhang and Chaoying Qin contributed equally to this work.  \n*Correspondence:  \nSaikat Dewanjee[saikat.dewanjee@jadavpuruniversity.in](saikat.dewanjee@jadavpuruniversity.in)[ ](saikat.dewanjee@jadavpuruniversity.in)Saurabh Kumar Jha  \n[jhasaurabh017@gmail.com](jhasaurabh017@gmail.com)[ ](jhasaurabh017@gmail.com)Qing Liu [liuqingdr@csu.edu.cn](liuqingdr@csu.edu.cn)  \n1 Department of Neurosurgery, Xiangya Hospital, Central South University, Changsha 410008, China  \n2 The Institute of Skull Base Surgery and Neuro-Oncology at Hunan Province, Changsha 410008, China  \n3 Advanced Pharmacognosy Research Laboratory, Department of Pharmaceutical Technology, Jadavpur University, Kolkata 700032, West Bengal, India  \n4 Centre of Research Impact and Outreach, Chitkara University Institute of Engineering and Technology, Chitkara University, Punjab, India  \n5 Department of Biotechnology, School of Applied & Life Sciences (SALS), Uttaranchal University, Dehradun 248007, India  \n6 Department of Biotechnology, School of Life Science and Biotechnology, Adamas University, Barasat, Kolkata 700126, West Bengal, India  \n7 Department of Zoology, Kalindi College, University of Delhi, New Delhi, Delhi 110008, India  \n© The Author(s) 2024.
