Summary
Complete tumor removal in gastric cancer surgery is key. Extensive lymph node dissection (LND) improves survival for moderate metastatic involvement, but its risks are debated in Western surgery.
Area of Science:
- Surgical Oncology
- Gastroenterology
Background:
- Complete tumor removal with clear margins is the goal in gastric cancer surgery.
- The extent of lymphadenectomy (LND) in gastric cancer treatment remains controversial.
- Japanese centers favor extensive LND, while Western surgeons cite risks of morbidity and mortality.
Purpose of the Study:
- To evaluate the impact and extent of lymphadenectomy in gastric cancer surgery.
- To determine the prognostic significance of lymph node involvement in gastric cancer.
Main Methods:
- Review of current surgical practices and randomized trials regarding lymphadenectomy in gastric cancer.
- Analysis of prognostic parameters including lymph node ratio and number of involved nodes.
Main Results:
- Extensive lymph node dissection is advocated by Japanese centers for excellent outcomes.
- Western surgeons express concerns about increased postoperative risks associated with extensive LND.
- Lymph node ratio and number of involved nodes are significant prognostic indicators.
- Survival improvement is achievable with moderate metastatic node involvement (pN0,1).
Conclusions:
- Systematic lymph node dissection should be integral to curative gastric cancer resection.
- Limited or no lymphadenectomy may be suitable for noncurative cases or specific early gastric cancers.
