Phase I/II trial of induction chemotherapy with docetaxel, cisplatin, and fluorouracil (DCF) followed by concurrent chemoradiotherapy in locally advanced esophageal squamous cell carcinoma.

4074 Background: Standard of care for unresectable locally advanced esophageal squamous cell carcinoma (ESCC) is concurrent chemoradiotherapy (CRT). However, its survival remains limited. Neoadjuvant chemotherapy with docetaxel, cisplatin and 5-FU (DCF) demonstrated promising activity with pathological complete response (CR) of 22% for resectable stage II/III ESCC (Hara H et.al, ASCO 2012). This study was performed to assess the efficacy and safety of induction chemotherapy with DCF followed by CRT in patients with unresectable locally advanced ESCC. Methods: Eligibility criteria included clinically T4 and/or M1 lymph node (LYM) ESCC, PS 0-1, and 20-70 years old. Treatment consisted of docetaxel 70 mg/m2, cisplatin 70 mg/m2 on day 1 and fluorouracil 750 mg/m2 on days 1 to 5, repeated every 3 weeks for three cycles, followed by cisplatin 70 mg/m2 on days 64 and 92, and fluorouracil 700 mg/m2on days 64 to 67 and 92 to 95 concurrently with radiotherapy (60Gy in 30 fractions, 5 days/week). Results: From Augus...
