Abstract
Forty-one patients with advanced gastric cancer underwent gastrectomy and the correlation between tissue uptake of the adjuvant drug and the prognosis were studied. The patients were preoperatively administered Tegafur (Futraful, Taiho Pharmaceutical Co. Ltd, Japan) and samples of tissue were obtained intraoperatively. 5-FU levels in the tumor and lymph nodes were measured by gas chromato-massfragmentography (GCMF). The patients in whom the 5-FU uptake by the tissues was measured and who were given over 60 g of Tegafur as postoperative adjuvant chemotherapy, were divided into two groups; namely, one group in whom the 5-FU uptake by the tumor tissue and lymph nodes was over 0.05 μg/g and the other in whom the uptake was lower than 0.05 μg/g. There were no significant differences in the background factors of either group. Each survival rate was calculated by the Kaplan-Meier method, and the generalized Wilcoxon method was used for statistical analysis. There was no statistically significant correlation between the 5-FU uptake by the tumor and the prognosis, however the 5-year survival rate in the group whose 5-FU uptake of the lymph nodes was over 0.05 μg/g was statistically significant (p=0.018).
