Background/Aims:
We retrospectively analyzed clinicopathologic data on 83 patients with advanced gastric cancer who underwent noncurative gastrectomy, with respect to the relation between the extent of lymphadenectomy and survival benefit.
Methodology:
These 83 patients were divided into 44 patients with limited or simple lymph node dissection (D0 in 14 and D1 in 30: Group A) and 39 patients with extended lymph node dissection (D2: Group B).
Results:
The 1-year survival rate in Group B (82.1%) was significantly higher than in Group A (49.0%). However, the 3-year and 5-year survival rates did not significantly differ between Group A versus Group B, 39.7% versus 25.7% and 39.7% versus 20.5%, respectively. Median survival time after surgery with and without distant metastasis in Group B (21.5 months) was longer than in Group A (16.4 months), although not significant.
Conclusions:
While gastrectomy with extended lymphadenectomy did not contribute to improve long-term survival in patients with noncurable advanced gastric cancer, the utility of extended lymph node dissections may be relevant to improved locoregional control, at least in the prognosis within 1 year after surgery. Not only extended lymphadenectomy but also aggressive chemotherapy may be needed to improve the long-term survival for such patients.
