1), and connective tissue projections radiating from this capsule, known as trabeculae, extend into the node. A fibrous capsule surrounds the outer layer of each LN (Fig.

Each LN is comprised of a complex series of lymphatic sinuses associated with organized parenchyma consisting of reticular fibers, fibroblastic reticular cells (FRCs), specialized vasculature, and a range of immune cell populations. 4, 5Īfferent lymphatic vessels deliver lymph to the LNs. 3 The human body contains an estimated 500 to 600 LNs that are surrounded by dense connective tissue and associated with particular nerves, lymphatic vessels, and blood vessels, with many of these LNs presenting in concentrated clusters found in specific anatomical locations. These discussions are further supported by a survey of approaches to the detection, diagnosis, and therapeutic management of metastatic LNs, thereby providing a comprehensive foundation for researchers and clinicians focused on the role of the lymphatic system in cancer.Īs central hubs for the induction of adaptive immunity, individual LNs process lymph containing local information from the tissues that drains via collecting lymphatic vessels from proximal tissues and organs. As such, this review was developed with the goal of providing a systematic overview of the physiological and anatomical characteristics of LNs, as well as the mechanistic basis for LNM and its clinical significance. Recent advances in medical technologies and LNM-focused research have enabled the more effective detection and treatment of LNM. 2 Lymph node metastasis (LNM) is thus a key consideration when evaluating cancer patients, as it has major implications for disease staging, clinical management, and prognostic outcomes.

1 Malignant tumor cells, however, can hijack the lymphatic system to facilitate their metastatic dissemination throughout the body, just like thieves using the ventilation ducts to move to various rooms in a building, and LNs serve as major hubs for metastatic cell growth, secondary dissemination to other tissue compartments, and the modulation of antitumor immune responses. Lymph nodes (LNs) serve as essential components of the mammalian immune system, functioning as a barrier against systemic pathogen dissemination while facilitating the induction and maturation of specific immune responses and serving as central hubs that orchestrate interactions among immune cell populations. And the novel exploration and academic disputes of strategies for recognition, diagnosis, and therapeutic interventions of metastatic LNs are also discussed. The clinical significance of LNM in different anatomical sites is summarized, including the roles of LNM playing in staging, prognostic prediction, and treatment selection for patients with various types of cancers. In this review, current knowledge of the anatomical and physiological characteristics of LNs, as well as the molecular mechanisms of LNM, are described. In recent years, with the updates in both basic and clinical studies on LNM and the application of advanced medical technologies, much progress has been made in the understanding of the mechanisms of LNM and the strategies for diagnosis and treatment of LNM. Therefore, it is important for oncologists to understand the mechanisms of tumor cells to metastasize to LNs, as well as how LNM affects the prognosis and therapy of patients with cancer in order to provide patients with accurate disease assessment and effective treatment strategies. Lymph nodes (LNs) are important hubs for metastatic cell arrest and growth, immune modulation, and secondary dissemination to distant sites through a series of mechanisms, and it has been proved that lymph node metastasis (LNM) is an essential prognostic indicator in many different types of cancer.
