Lateral lymph node dissection in advanced low rectal cancer treatment

Area of Science:

• Surgical Oncology
• Gastroenterology
• Rectal Cancer Research

Background:

• Lateral lymph node (LLN) metastasis is a key factor in local recurrence for advanced low rectal cancer.
• While neoadjuvant chemoradiotherapy (nCRT) and total mesorectal excision (TME) are standard, LLN metastasis and recurrence persist.
• Lateral lymph node dissection (LLND) is employed in Japan for Stage II/III advanced low rectal cancer to address LLN metastasis.

Purpose of the Study:

• To review existing literature on Lateral Lymph Node Dissection (LLND) for advanced low rectal cancer.
• To evaluate the efficacy and application prospects of LLND in improving oncological outcomes.
• To discuss the role of LLND in enhancing patient survival and quality of life.

Main Methods:

• Retrospective review of previous reports on LLND.
• Analysis of LLND's effectiveness in reducing local recurrence rates.
• Examination of minimally invasive approaches like laparoscopic and robotic-assisted LLND.

Main Results:

• LLND has demonstrated effectiveness in removing metastatic lymph nodes, leading to decreased local recurrence rates.
• Despite its benefits, LLND is associated with complexity and complications, leading to ongoing debate regarding its use.
• Minimally invasive LLND techniques are recognized as valuable tools for pre-operative LLN status evaluation.

Conclusions:

• LLND is a crucial component in the surgical management of advanced low rectal cancer, particularly in regions like Japan.
• Further research is essential to refine LLND techniques and improve oncological outcomes.
• LLND holds significant potential for enhancing long-term patient survival and quality of life in rectal cancer treatment.
