![]() 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. March 9, 2023.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. Labeling of drug preparations containing salicylates.Recommendations for prevention and control of influenza in children, 2022-2023. Acute mesenteric lymphadenitis in children: Findings related to differential diagnosis and hospitalization. Causes of acute abdominal pain in children and adolescents. ![]() Risk factorsĪny infection that causes inflammation and swelling in the lymph nodes in the tissue that attaches the bowel to the abdominal wall increases the risk of mesenteric lymphadenitis.Ĭonditions that raise the risk of mesenteric lymphadenitis include: Other causes of mesenteric lymphadenitis include bacterial infection, inflammatory bowel disease and lymphoma. This infection causes inflammation and swelling in the lymph nodes in the thin tissue that attaches the intestine to the back of the wall around the stomach area, called mesentery. Gastroenteritis is often called stomach flu. The most common cause of mesenteric lymphadenitis is a viral infection, such as gastroenteritis. Tenderness to touch of the stomach area.Īlso, call a healthcare provider for a child who has pain in the stomach area that doesn't get better in a short time and who also:.Stomach area pain with diarrhea or vomiting.Sudden, severe pain in the stomach area.So it can be hard to know when to seek medical advice.Ĭall a healthcare professional right away for a child who has: Pain in the stomach area is common in children and teens. General tenderness of the stomach area.ĭepending on what's causing the condition, symptoms also might include:.Pain in the stomach area, often on the lower right side, but the pain can be more spread out.Possible symptoms of mesenteric lymphadenitis include:
