Effect of extensive lymph node dissection on the survival of early gastric cancer
1First Department of Surgery, Kyoto Prefectural University of Medicine, Japan.
Background/Aims:
A retrospective analysis of 628 cases of early gastric cancer was performed to evaluate prognostic significance of extensive lymph node dissection.
Methodology:
The patients were assigned to either D0/D1 (n=177) group or D2/D3 group (n=451) according to the extent of lymph node dissection and the survival of the two groups was compared.
Results:
The survival rate of D2/D3 group was significantly higher than D0/D1 group in the case of both including and excluding unrelated cause of death (p<0.0001 and p<0.005, respectively).
Conclusions:
Though early gastric cancer is excellent prognostic disease, very few numbers of patients with recurrence really remain. Our data show extensive lymph node dissection was effective to prolong the survival of patients with early gastric cancer.
