Irsogladine Maleate intensifies the degree of intercellular contact so we expected that a combination of Irsogladine Maleate and UFT would cause tumor-reducing effect and normalization of the malignant cells. A combination of Irsogladine Maleate and UFT was administered to 2 patients with inoperable gastric cancer (Case 1: An 83-year-old male: Borrmann type I, Case 2: A 93-year-old female: A relatively wide early gastric cancer), marked tumor reduction was obtained in both cases. The doses administered were 4 mg/day of Irsogladine Maleate and 200 mg/day of UFT.
