Abstract

Soft tissue sarcomas (STS) are malignancies derived from connective tissue, and regional lymph node metastasis (RLNM), while not common, is an important aspect of prognosis and treatment. Various risk factors, in particular the histological subtype, affect the likelihood of nodal involvement, which can be characterized by imaging features such as nodal dimension and morphology. Currently, surveillance and management vary by institution, as concrete societal guidelines have not been established. Common nodal status assessment strategies include physical exam, US CT, MRI, sentinel lymph node biopsy (SLNB) and radical lymphadenectomy. This article summarizes data regarding relevant risk factors of RLNM, imaging features, and any available data regarding surveillance recommendations.

软组织肉瘤的淋巴结转移：危险因素，影像学发现及其影响

摘要

软组织肉瘤（STS）是源自结缔组织的恶性肿瘤，区域淋巴结转移（RLNM）虽然不常见，但却是预后和治疗的重要方面。各种危险因素，特别是组织学亚型，影响淋巴结受累的可能性，其特征可能在于影像学特征，如淋巴结大小和形态。目前，由于尚未建立具体的社会指导方针，监督和管理因机构而异。常见的淋巴结状态评估策略包括体格检查，US CT，MRI，前哨淋巴结活检（SLNB）和根治性淋巴结清扫术。本文总结了有关RLNM的相关危险因素，影像学特征的数据以及有关监测建议的任何可用数据。
