Surgical outcome of node-positive early gastric cancer with particular reference to nodal status.

Abstract

BACKGROUND:

The risk of recurrence according to nodal status in patients with node-positive early gastric cancer (EGC) remains unclear and no appropriate treatment approaches have yet been established for such patients.

MATERIALS AND METHODS:

The surgical outcome of gastrectomy in combination with lymphadenectomy was examined in a total of 100 patients (54 males and 46 females, ranging in age from 25 to 84 years; average 56.6 years) with EGC and metastasis to lymph nodes. The outcome was assessed with particular reference to the extent of lymph node metastasis.

RESULTS:

The 5 and 10-year overall survival rates were 93.5 and 89.8%, respectively. Significant differences in survival were detected when anatomical distribution of lymph node metastasis (p < 0.0001), number of positive nodes (p = 0.0004) and tumor size (p = 0.0085) were examined. In particular, in 73 patients for whom the metastasis was limited to a perigastric node, prognosis was excellent and no recurrence was observed during the follow-up period. On the other hand, 27 patients with metastasis to a lymph node beyond the perigastric region were defined as comprising a high risk group for recurrence among node-positive EGC patients due to their poor prognosis (10-year survival rate, 58.5%).

CONCLUSION:

The results of the present study have suggested that radical gastrectomy combined with lymphadenectomy is essential to achieve complete remission in patients with lymph node metastasis restricted to perigastric nodes. For patients with a high risk of recurrence in EGC, whose condition is complicated by lymph node metastasis beyond the perigastric region, care should be taken to prevent recurrence by conducting long-term follow-up even after radical surgery. In order to improve survival, an appropriate protocol for post-operative adjuvant therapy may be needed for patients such as those with advanced gastric cancer.
