    Abstract:
    The purpose of these studies is to evaluate the anticancerous effects of tegafur suppository and Glutathione (GSH) as enhanced drug and compare the difference of the histopathological effects and tissue concentration of 5-FU and FT-207 in gastric and colon cancer. Thirty three patients with gastric cancer and 17 with colon cancer were treated by tegafur suppository at a dose of 1,500 mg/day and GSH, 1,200 mg/day intravenously. These patients were clinically divided into two groups, one of which was treated with tegafur suppository (Group A) and another administered with suppository and GSH (Group B). Five-fluorouracil was measured by GC-MF method and FT-207 was also done by HPLC method. After surgery, relationship between tissue concentration of 5-FU and histopathological effects were investigated. In gastric cancer, 5-FU concentration in cancer tissue was significantly kept high level in cancer tissue in patients treated with tegafur and GSH (Group B). However, there was no same results in colon cancer. These results seemed to be the difference of organ specificity. According to histopathological studies, well differentiated adenocarcinoma including papillary carcinoma were markedly effective compared to poorly differentiated adenocarcinoma in both cancer. This difference of anticancerous effect was supposed to be microangiographically different of microvascular architecture and quantity of anticancerous agents in tumor.
