[High tissue concentration of 5-FU reduced local recurrence after administration of tegafur suppositories].
1995
Forty-two patients with head and neck cancer were treated with tegafur suppository for 7 days preoperatively and clinical value of this treatment was assessed. In a group which indicated tumor tissue concentrations of 5-FU were more than 0.5 micrograms/g, local recurrence decreased in the period of postoperative observation for 42 months. A survival rate of this group was better than others. From these results, preoperative tegafur suppository treatment seemed to have a role in expectation of improvement of local control in head and neck cancer therapy.
