Lymph Node Dissection Techniques in Gastric Cancer Surgery
Summary
Gastric cancer remains one of the leading causes of cancer-related death worldwide, and surgical resection with lymphadenectomy is the only potentially curative option. Lymphadenectomy—the systematic removal of regional lymphatic tissue—serves both staging and therapeutic purposes by identifying micrometastatic spread and reducing residual disease. The classification into D1 (perigastric stations only) and D2 (extended clearance of second-tier nodes along the coeliac axis and major vessels) underlies most international guidelines. Randomised trials and meta-analyses have shown that D2 dissection offers a clinical trend towards improved long-term survival compared with D1, albeit with greater technical complexity and potential for morbidity. Contemporary practice seeks to preserve uninvolved organs, avoiding routine splenectomy or pancreatectomy, and to harness minimally invasive approaches—laparoscopic and robotic—to enhance precision and reduce recovery times. Sentinel node navigation and augmented intraoperative imaging are emerging tools to tailor the extent of dissection in early disease. High-volume centres increasingly implement structured quality assurance frameworks, using photographic landmarks and standardised checklists to ensure consistency across surgeons and institutions. As neoadjuvant therapies evolve and multidisciplinary care expands, the balance between oncological radicality and patient safety continues to drive refinement of lymph node dissection strategies in gastric cancer surgery.

Lymph Node Dissection Techniques in Gastric Cancer Surgery publication trend
The graph below shows the total number of articles in lymph node dissection techniques in gastric cancer surgery across all publications each year (not limited to Nature Index journals).
Technical terms
Lymphadenectomy: Surgical removal of regional lymph nodes and surrounding tissue for staging and therapeutic clearance of metastatic spread.
D1 lymphadenectomy: Limited dissection of perigastric lymph node stations immediately adjacent to the stomach.
D2 lymphadenectomy: Extended dissection including second-tier nodes along the coeliac trunk, hepatic and splenic arteries.
Gastrectomy: Surgical excision of part or all of the stomach as treatment for gastric malignancy.
Minimally invasive gastrectomy: Gastrectomy performed via laparoscopic or robotic techniques to reduce surgical trauma.
Restricted mean survival time: A statistical measure of average survival up to a specified follow-up period, used to compare treatment efficacy.
Surgical quality assurance tool: A structured set of anatomical landmarks and scoring criteria designed to assess lymphadenectomy completeness.
