  S-1, an oral anticancer drug, is comprised of tegafur (a prodrug of 5-fluorouracil) and two biochemical modulators that have effect-enhancing and adverse reaction-reducing activities. Neoadjuvant chemotherapy (NAC) using S-1 has not been reported. Between April 2003 and March 2008, 103 patients with previously untreated oral squamous cell carcinoma (OSCC) received some courses of S-1 NAC (S-1 80 mg/m2/day as the NAC until 1 week preoperatively).
