Abstract

Lymph nodes (LNs) are principal orchestrators of the adaptive immune response, yet in the context of malignancy, they are typically the first sites of metastasis. When tumors spread to LNs, they alter the immune repertoire, ultimately reconditioning it in a manner that suppresses anti-tumor immunity and promotes further metastatic dissemination. Conversely, activation of anti-tumor immunity within LNs is essential for immunotherapy, suggesting clinical approaches to radiotherapy in LNs and lymphadenectomy may need to be reconsidered in the context of immune checkpoint blockade (ICB). Herein, we discuss our understanding of the immune remodeling that coincides with LN metastasis as well as recent clinical studies exploring neoadjuvant immunotherapy and the roles of LNs in treatment of solid organ malignancies.

探究淋巴结转移在全身免疫监视中的作用
摘要 淋巴结(LN)是适应性免疫反应的主要协调者,但在恶性肿瘤中,淋巴结通常是最先转移的部位。当肿瘤扩散到淋巴结时,它们会改变免疫程序,最终以抑制抗肿瘤免疫和促进进一步转移扩散的方式重新调节免疫程序。相反,激活淋巴结内的抗肿瘤免疫对免疫疗法至关重要,这表明在免疫检查点阻断(ICB)的背景下,可能需要重新考虑淋巴结放疗和淋巴腺切除的临床方法。在此,我们将讨论我们对LN转移同时发生的免疫重塑的理解,以及最近探索新辅助免疫疗法的临床研究和LN在治疗实体器官恶性肿瘤中的作用。

期刊介绍: The Journal''s scope encompasses all aspects of metastasis research, whether laboratory-based, experimental or clinical and therapeutic. It covers such areas as molecular biology, pharmacology, tumor biology, and clinical cancer treatment (with all its subdivisions of surgery, chemotherapy and radio-therapy as well as pathology and epidemiology) insofar as these disciplines are concerned with the Journal''s core subject of metastasis formation, prevention and treatment.
