Purpose
Adjuvant chemotherapy is an indispensable component of treatment for preventing recurrence in advanced gastric cancer patients after macroscopically complete tumor resection (R0). However, the efficacy of this treatment for patients with T2N0 and T3N0 gastric cancer is not well characterized.
Methods
This study examined 1019 T1, 126 T2N0, and 67 T3N0 gastric adenocarcinoma patients who underwent gastrectomies at our institution between 1975 and 2005 to determine the predictive factors for recurrence in T2N0 and T3N0 gastric cancer patients.
Results
Among 193 T2N0 and T3N0 patients, 14 patients (7.3 %) have recurred. The prevalence of ly2/3 and v2/3 was significantly higher in patients with recurrence compared with those without recurrence. The prognosis for either T2N0 or T3N0 gastric cancer patients was significantly worse than that for T1 gastric cancer patients. Multivariate analysis indicated that lymphatic and blood vessel invasion were independent prognostic indicators in T2N0 and T3N0 gastric cancer patients. Ten-year survival rates for T2N0 and T3N0 gastric cancer patients with both ly2/3 and v2/3, with either ly2/3 or v2/3, and without ly2/3 and v2/3 were 42.9, 86.1, and 96.7 %, respectively. T2N0 and T3N0 gastric cancer patients with both ly2/3 and v2/3 had a significantly worse prognosis than that of patients with either ly2/3 or v2/3 and those without ly2/3 and v2/3.
Conclusions
Our data indicate that T2N0 and T3N0 patients with both ly2/3 and v2/3 have a high risk of recurrence. Therefore, adjuvant chemotherapy should be administered to these patients.
