Area of Science:

  • Oncology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Sentinel node mapping and biopsy (sentinel node navigation surgery) theoretically limit surgical dissection and associated morbidity in gastric cancer.
  • Clinical application challenges have previously dampened interest, but the rise of laparoscopic techniques has reignited research.
  • Double tracer methods show promise over single tracer techniques for improved accuracy.

Purpose of the Study:

  • To explore the principles and evolving role of sentinel node navigation surgery in gastric cancer.
  • To highlight advancements in lymph node detection technologies and their potential impact.
  • To define the current applicability of sentinel node navigation surgery in early gastric cancer management.

  • Review of the theoretical basis for sentinel node navigation surgery.
  • Discussion of advancements in minimally invasive laparoscopic gastric cancer resection.
  • Overview of emerging lymph node detection technologies (e.g., infrared endoscopy, fluorescence imaging, near-infrared technology).
  • Assessment of the role of hematoxylin/eosin staining in metastatic evaluation.
  • Intraoperative sentinel lymph node status determination guiding further lymph node dissection.

    • Main Results:

    • Double tracer methods are considered superior to single tracer techniques.
    • New detection methods utilizing advanced technologies are under development.
    • Hematoxylin/eosin staining remains the standard for lymph node metastasis assessment despite limitations.
    • Intraoperative confirmation of metastasis in sentinel nodes mandates further lymph node dissection.
    • Sentinel node status characterization guides tailored lymphadenectomy.

    Conclusions:

    • Sentinel node navigation surgery, combined with laparoscopic resection, is a viable option for early gastric cancer.
    • This approach aims to minimize unnecessary lymph node dissection and reduce patient morbidity.
    • For T3 or more advanced gastric cancers, conventional resection with standard lymph node dissection remains the recommended management.
