There has historically been a significant divide in the approach to the management of lateral pelvic lymph nodes in patients with rectal cancer. These differing paradigms have developed based upon competing priorities. In the West, the circumferential resection margin has been the main focus because it is a strong predictor of local recurrence, distal recurrence, and survival. This approach was supplemented by radiation and chemotherapy to treat the lateral pelvic lymph nodes and micrometastatic disease. In the East, lateral pelvic lymph nodes are considered to be locoregional; thus, surgical treatment has traditionally included routine dissection of this compartment for low rectal cancers without the use of neoadjuvant chemoradiotherapy. However, neither approach has adequately addressed the important issue of lateral compartment recurrence in patients with clinically evident lateral pelvic lymph node metastasis. The aims of the review were to present the recent key studies and evolution of lateral pelvic lymph node management in locally advanced rectal cancer and secondly to propose a management strategy for the lateral compartment based on the current evidence.
在管理直肠癌患者侧盆淋巴结方面,历史上存在着显著的分歧。这些不同的模式是基于相互竞争的优先事项发展起来的。在西方,环周切缘一直是主要关注点,因为它是局部复发、远端复发和生存的强有力预测因素。这种方法通过放射治疗和化学疗法来治疗侧盆淋巴结和微转移疾病。在东方,侧盆淋巴结被认为是局部区域的;因此,手术治疗传统上包括对低位直肠癌进行常规解剖,而不使用新辅助放化疗。然而,这两种方法都没有充分解决有临床明显侧盆淋巴结转移的患者中侧盆区复发的重要问题。本综述的目的是介绍局部进展期直肠癌中侧盆淋巴结管理的最新关键研究和演变,其次是根据现有证据提出侧盆区的管理策略。
