Further study details as provided by Japan Clinical Oncology Group:

Primary Outcome Measures:
  • overall survival

Secondary Outcome Measures:
  • relapse-free survival
  • operative morbidity and mortality
  • length of postoperative hospital stay
  • quality of life

Estimated Enrollment: 520
Study Start Date: July 1995
Estimated Study Completion Date: April 2006
Detailed Description:
Radical gastrectomy with regional lymphadenectomy is the only curative treatment option for gastric cancer. The extent of lymphadenectomy, however, is controversial. The two European randomized trials only reported an increase in operative morbidity and mortality, but failed to show survival benefit, in the D2 lymphadenectomy group. We conducted a randomized controlled trial to compare the Japanese standard D2 and D2 + para-aortic nodal dissection.
