Purpose The aim of this study was to evaluate the activity and safety of oxaliplatin/5-Xuorouracil-based chemo-radiotherapy in patients with not radically resectable locally advanced esophageal cancer. Methods Fifty-nine patients with adeno or squamous-cell carcinoma received oxaliplatin (60 mg/m(2)), and leucovorin (20 mg/m2 on days 1,8,15,29,36,43,50,57) followed by continuous infusion fluorouracil (200 mg/m2 per day on days 1-22 and 29-64) with radiotherapy (1.8 Gy daily fractions to a total dose of 45 Gy, from days 29 to 64). When feasible, surgery was scheduled 6-8 weeks after chemoradiotherapy completion. The primary endpoint was 1-year progression-free survival. Results Forty (68%) patients completed treatment without modifications. An objective clinical response was seen in 35 patients (59%). Esophagectomy was possible in 33 patients and a complete resection (R0) was achieved in 26 (79%) with 6 pathologic complete responses (pCR) and 3 near pCR. At a median follow-up of 39.7 months for the surviving patients, the median progression-free and overall survivals were 11 months (95% CI 6.5-14) and 18.5 months (95% CI 13-29). The 1-year progression-free and overall survivals were 47.5% (95% CI 34-59.5%) and 63% (95% CI 49 74%). Major toxicities were esophagitis (20% G3 and 5% G4) and diarrhea (8.5% G3 and 8.5% G4). Hematological toxicity (7% G3 and 3% G4) was less common; severe neurotoxicity (3% G3) was infrequent. Conclusions Concurrent oxaliplatin, leucovorin, fluorouracil and radiotherapy followed or not by esophagectomy has a tolerable toxicity and promising activity in locally advanced esophageal cancer.

Methods Fifty-nine patients with adeno or squamous-cell carcinoma received oxaliplatin (60 mg/m(2)), and leucovorin (20 mg/m2 on days 1,8,15,29,36,43,50,57) followed by continuous infusion fluorouracil (200 mg/m2 per day on days 1-22 and 29-64) with radiotherapy (1.8 Gy daily fractions to a total dose of 45 Gy, from days 29 to 64). When feasible, surgery was scheduled 6-8 weeks after chemoradiotherapy completion. The primary endpoint was 1-year progression-free survival. Results Forty (68%) patients completed treatment without modifications. An objective clinical response was seen in 35 patients (59%). Esophagectomy was possible in 33 patients and a complete resection (R0) was achieved in 26 (79%) with 6 pathologic complete responses (pCR) and 3 near pCR. At a median follow-up of 39.7 months for the surviving patients, the median progression-free and overall survivals were 11 months (95% CI 6.5-14) and 18.5 months (95% CI 13-29).
