Aim: To clarify the clinical significance of definitive chemoradiotherapy (CRT) and CRT followed by esophagectomy for cT4 esophageal cancer. Patients and Methods: The treatment results for cT4 esophageal cancer were examined in 81 patients who received definitive CRT [radiation 50-70 Gy, cisplatin and 5-fluorouracil; group I] and 19 patients who underwent esophagectomy after preoperative CRT [40Gy, Group II]. Results: Among the 81 patients in group I, toxicities (grade 3 or 4) were observed in 32 patients, while partial response and complete response were recognized in 8 and 47 patients, respectively. Of the 19 group II patients, an R0 resection was performed in 16 patients, and the mortality rate was 5%. The 5-year survival rates were 19% and 42% in groups I and II, respectively. Conclusion: Long-term survival can be expected after multimodal therapy, even for patients with cT4 esophageal cancer. Esophagectomy is therefore a valid treatment option when down-staging can be achieved.
