Node-positive Mucosal Gastric Cancer: a Follow-up Study

Background: Lymph node metastasis from mucosal gastric carcinoma is rare and the prognosis of the patients has seldom been reported.

Methods: Forty-five patients with node-positive mucosal gastric cancer were studied. They accounted for 2.5% of 1770 patients with mucosal gastric cancer who underwent gastrectomy with lymphadenectomy at the National Cancer Center Hospital, Tokyo. The clinicopathological features were studied and the current clinical status was sought.

Results: The majority of patients (87%) were treated with D2 lymphadenectomy. The metastasis was confined to the perigastric nodes (pN1 by Japanese classification) in 30 patients (67%). The number of positive nodes was less than seven (pN1 by TNM) in 42 patients (93%). Two patients had para-aortic nodal metastasis. The median follow-up period was 11 years. Four patients died of definite or possible recurrent disease and the disease-specific 5- and 10-year survival rates were 95 and 89%, respectively.

Conclusions: Although nodal metastasis is an important prognostic factor for gastric cancer, the prognosis was excellent as long as the primary tumor was confined to the mucosa and was treated with gastrectomy and lymphadenectomy.
