Nodal dissemination in locally advanced rectal cancer occurs mainly in two directions: upward and lateral. Lateral node involvement has been demonstrated; however, lateral lymph node dissection (LLND) is not routinely performed in Western countries and the focus is more on neoadjuvant treatment regimens. The main reasons for this are the high morbidity associated with the operation and the uncertain oncological benefit. There is, however, recent evidence that in selected cases, neoadjuvant treatment combined with total mesorectal excision only might not be sufficient. In this article, the historical developments in the East and the West, the current evidence regarding lateral nodal disease, and the surgical steps in the LLND are discussed.
局部进展期直肠癌的淋巴结播散主要发生在两个方向
向上和侧向。侧向淋巴结受累已得到证实;然而,西方国家并不常规进行侧方淋巴结清扫(LLND),而是更侧重于新辅助治疗方案。其主要原因是手术相关的高发病率以及肿瘤学获益的不确定性。然而,最近有证据表明,在某些特定病例中,仅新辅助治疗联合全直肠系膜切除术可能并不足够。本文讨论了东西方的历史发展、关于侧方淋巴结疾病的当前证据以及LLND的手术步骤。
