Our previous trial with a docetaxel, cisplatin, and 5-fluorouracil (DCF) regimen showed high response rates in metastatic squamous cell carcinoma of the esophagus (SCCE). The observed increased toxicity of the DCF regimen, however, was clinically harmful. S-1, an oral anticancer drug, has been approved as a combination therapy for SCCE, and alternate-day regimen with S-1 has shown lower levels of toxicity. This prospective single-center phase I/II trial examines the efficacy and toxicity of a combination of docetaxel, cisplatin, and an alternate-day regimen of S-1 (modified DCS) for patients with metastatic SCCE...
