Summary
Vascularizing lymph node dissection (VLND) offers a survival benefit for advanced gastric cancer patients compared to non-vascularizing lymph node dissection (NVLND). This technique is safe and feasible for potentially curable cases.
Area of Science:
- Surgical Oncology
- Gastrointestinal Surgery
Background:
- Advanced gastric cancer requires effective lymph node dissection for curative intent.
- Comparing vascularizing lymph node dissection (VLND) and non-vascularizing lymph node dissection (NVLND) is crucial for optimizing treatment outcomes.
Purpose of the Study:
- To compare the short- and long-term outcomes of VLND versus NVLND in patients with advanced gastric cancer.
Main Methods:
- A retrospective analysis of 315 patients with advanced gastric cancer undergoing D2 lymphadenectomy.
- Patients were divided into two groups: 152 received VLND and 163 received NVLND.
- Short- and long-term clinical outcomes were compared between the groups.
Main Results:
- No significant difference in postoperative complication rates between VLND (13.2%) and NVLND (11.7%) groups (P = 0.686).
- The overall 5-year survival rate was higher in the VLND group (64%) compared to the NVLND group (59%) (P = 0.047).
- VLND demonstrated a survival benefit in subgroups with Bormann type III/IV, undifferentiated type, or lymph node metastasis.
Conclusions:
- D2 VLND in advanced gastric cancer treatment provides a survival benefit with acceptable morbidity and mortality.
- VLND is a feasible and safe procedure for potentially curable advanced gastric cancer when performed by experienced surgical teams.
