Title: Definitive Chemoradiation Therapy With Docetaxel, Cisplatin, and 5-Fluorouracil (DCF-R) in Advanced Esophageal Cancer: A Phase 2 Trial (KDOG 0501-P2)

Purpose: A previous phase 1 study suggested that definitive chemoradiation therapy with docetaxel, cisplatin, and 5-fluorouracil (DCF-R) is tolerable and active in patients with advanced esophageal cancer (AEC). This phase 2 study was designed to confirm the efficacy and toxicity of DCF-R in AEC. Methods and Materials: Patients with previously untreated thoracic AEC who had T4 tumors or M1 lymph node metastasis (M1 LYM), or both, received intravenous infusions of docetaxel (35 mg/m{sup 2}) and cisplatin (40 mg/m{sup 2}) on day 1 and a continuous intravenous infusion of 5-fluorouracil (400 mg/m{sup 2}/day) on days 1 to 5, every 2 weeks, plus concurrent radiation. The total radiation dose was initially 61.2 Gy but was lowered to multiple-field irradiation with 50.4 Gy to decrease esophagitis and late toxicity. Consequently, the number of cycles of DCF administered during radiation therapy was reduced from 4 to 3. The primary endpoint was the clinical complete response (cCR) rate. Results: Characteristics of the 42 subjects were: median age, 62 years; performance status, 0 in 14, 1 in 25, 2 in 3; TNM classification, T4M0 in 20, non-T4M1LYM in 12, T4M1LYM in 10; total scheduled radiation dose: 61.2 Gy in 12, 50.4 Gy in 30. The cCRmore » rate was 52.4% (95% confidence interval [CI]: 37.3%-67.5%) overall, 33.3% in the 61.2-Gy group, and 60.0% in the 50.4-Gy group. The median progression-free survival was 11.1 months, and the median survival was 29.0 months with a survival rate of 43.9% at 3 years. Grade 3 or higher major toxicity consisted of leukopenia (71.4%), neutropenia (57.2%), anemia (16.7%), febrile neutropenia (38.1%), anorexia (31.0%), and esophagitis (28.6%). Conclusions: DCF-R frequently caused myelosuppression and esophagitis but was highly active and suggested to be a promising regimen in AEC. On the basis of efficacy and safety, a radiation dose of 50.4 Gy is recommended for further studies of DCF-R.« less
