RESUMO
We report a successful case of chemotherapy with oral fluoropyrimidines. The patient was an 81-year-old woman who complained epigastric discomfort. Endoscopy revealed a type 3 advanced gastric cancer, and the biopsy specimen was defined histologically as poorly-differentiated adenocarcinoma. She didn't hope for an operation, but agreed to receive chemotherapy. S-1 (80 mg/day) was administered for 14 days, followed by 7 days rest. This schedule induced grade 1 thrombocytopenia and fatigue after two weeks administration. Therefore, we reduced the administration dosage to 60 mg/ day. Almost complete response (CR) was observed after 8 weeks of S-1 administration. But she was admitted urgently to other emergency hospital for stumbling due to dizziness accompanied with vomiting and anorexia. We considered it was difficult to continue S-1 administration. Therefore, we changed S-1 to UFT-E and started from 300 mg/day. One month later, as the adverse effects were not recognized, we increased a dosage of UFT-E to 400 mg/day for the purpose of more dose intensity. After 6 months, CR was confirmed continuously. We reduced UFT-E to 300 mg/day, and CR has been continued for 3 years until now without any adverse events. There was no evidence regarding the best timing to syop anticancer administration. As the adverse effect was very mild and her quality of life improved, we continued UFT-E administration for a long time.
