低位直肠癌选择性侧方淋巴结清扫研究进展

盆腔侧方淋巴结(Lateral pelvic lymph node,LPLN)是低位直肠癌患者常见的局部转移部位,同时也是术后局部复发的主要部位,然而目前对于LPLN转移的治疗方案仍没有明确的定论.同时LPLN的转移应被看作是局部而不是全身,新辅助放化疗(Chemoradiotherapy,CRT)并不能替代手术清扫,...

Research progress of selective lateral lymph node dissection in low rectal cancer

Lateral pelvic lymph node(LPLN)is a common local site of metastasis in patients with low rectal cancer,and it is also the main site of postoperative local recurrence.However,there is still no clear conclusion about the treatment plan for LPLN metastasis.At the same time,the metastasis of LPLN should be regarded as local diseases rather than systemic.Neoadjuvant radiotherapy and chemotherapy(CRT)cannot replace surgical dissection.Lateral lymph node dissection(LLND)is still indispensable.However,since LLND may mean longer operative time and more postoperative complications,it may be over-treatment for all patients with low rectal cancer,so it is particularly important to select patients who can benefit.The size of the LPLN,the reduction ratio of the short path,the signal strength,and the edge characteristics should all be considered in the screening.
