Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Background:

  • Lateral lymph node dissection (LLND) is crucial for low rectal cancer treatment.
  • Its goal is to resect lateral pelvic lymph nodes, preventing metastasis and recurrence.
  • LLND is standard in Japan but controversial in Europe and North America, where neoadjuvant chemoradiotherapy (nCRT) is dominant.

Purpose of the Study:

  • To provide a comprehensive analysis of LLND for low rectal cancer.
  • To review the technical evolution, clinical efficacy, and controversies surrounding LLND.
  • To guide the rational application and optimization of LLND in clinical practice.

Main Methods:

  • Integration of the latest clinical research findings on LLND.
  • Analysis of the technical evolution and clinical efficacy of LLND.
  • Objective presentation of academic controversies and future developments.

Main Results:

  • LLND aims to improve outcomes in low rectal cancer by addressing lateral pelvic lymph nodes.
  • The efficacy and application of LLND are debated, with differing standards in Japan versus Europe/North America.
  • Ongoing research and technical advancements are shaping the future of LLND.

Conclusions:

  • LLND remains a significant intervention for low rectal cancer, despite ongoing debate.
  • A thorough understanding of its efficacy, controversies, and technical aspects is essential for optimal patient care.
  • Future developments may further refine the role of LLND in rectal cancer treatment.
