They comprise a group of malignant tumours originating from various locations along the GI tract, from the oesophagus to the anus, including supportive glands like liver and pancreas [1] . The most common GI cancers arise in the epithelial tissue of the oesophagus, stomach, pancreas, liver, and colorectum. With 4 .9 million new cases and 3 .9 million deaths in 2020, GI cancers are among the leading cause of cancer-related fatality in both genders [2] .  \nThe majority of GI cancer mortality is associated with metastasis—a complex, multistep process involving systemic spread of tumour cells from the primary site throughout the body, followed by colonisation of secondary organs. The standard of care for GI cancer patients includes approaches such as surgery, chemotherapy, radiotherapy, targeted therapy and immunotherapy. However, once the tumour has metastasised to distant organs, with lungs and liver being the most frequent sites, therapeutic options become increasingly narrower [3–6] . Typically, metastatic lesions become clinically visible in GI cancer patients in the years that follow surgical removal of the primary tumour [7–10] . Hence, identifying key drivers of the metastatic process is an essential step to facilitate the development of novel therapeutic strategies that may prevent and/or eradicate metastasis.  \nIn case of most solid tumours, including GI malignancies, growing cancerous lesions may shed cells in the bloodstream which can travel to distant organs and form metastases. These pioneers of the metastatic process are referred to as circulating  \ntumour cells (CTCs) . Though relatively little is known about the mechanisms that inﬂuence dissemination and seeding of CTCs, it is well proven that increased numbers of CTCs in blood correlate with poor prognosis in patients [11] . Owing to the rarity of these cells in the peripheral circulation and a limited set of biomarkers for their identiﬁcation, isolation of CTCs has been notoriously challenging [12] . Several technologies, each with their own set of advantages and disadvantages, are employed for CTC isolation in GI cancers. They can be broadly divided into two categories: antigen-dependent (based on the unique markers expressed by tumour cells but absent in other circulating blood cells) and antigen-independ","cbCaidFOHJWiT51N","https://ap.wps.com/l/cbCaidFOHJWiT51N","pdf",729992,"English","# Introduction\n## Clinical relevance of CTCs in GI cancers\n## CTC isolation technologies (antigen-dependent vs antigen-independent)\n## Prognostic utility and clinical monitoring","[{\"question\":\"What role do circulating tumour cells (CTCs) play in gastrointestinal cancer metastasis?\",\"answer\":\"CTCs support metastasis formation by traveling from the primary GI site to secondary organs.
