Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Context:

  • Open surgery is the standard approach for gastric cancer treatment in Japan.
  • Guidelines recommend open surgery for standard gastrectomy and extended procedures.
  • Advanced gastric cancer (AGC) and specific patient groups benefit from open surgery.

Purpose:

  • To outline the advantages of open surgery for gastric cancer.
  • To discuss standard and extended surgical procedures for gastric cancer.
  • To highlight the need for evidence-based validation of extended surgical strategies.

Summary:

  • Open surgery is recommended for gastric cancer, encompassing standard gastrectomy (resection of two-thirds of the stomach with D2 lymphadenectomy) and various extended procedures.
  • Extended surgeries include para-aortic lymph node dissection, pancreatectomy, and resection for liver metastasis or esophageal invasion.
  • While beneficial for specific cases like Stage IV or remnant stomach cancer, extended surgical treatments for AGC are considered experimental and require further scientific evidence.

Impact:

  • Emphasizes the established role of open surgery in gastric cancer management.
  • Identifies specific advanced gastric cancer scenarios where open surgery is applied.
  • Stresses the critical need for scientific validation of extended surgical approaches in multidisciplinary treatment plans.
