Tumor deposits (TDs) are clusters of tumor cells found in adipose and fibrous tissues near the primary tumor in various cancers, including colorectal and gastric cancer. They lack lymphoid structures and are not directly linked to the primary tumor. The 8th edition of TNM staging defines TDs as tumor cell deposits without identifiable vascular or neural structures, affecting patient survival and increasing the risk of metastasis. However, current diagnostic methods rely on postoperative pathology, limiting early evaluation. Research on preoperative imaging methods to predict TDs is ongoing to improve patient outcomes through more tailored treatment plans.
