Background and Objectives Since the prognosis of patients with T4 squamous cell carcinoma (SCC) of the esophagus is extremely poor, an effective multimodal treatment needs to be established. Methods Forty‐five patients with SCC of the esophagus at the T4 classification of the disease but no hematogenous metastasis were treated with concurrent chemoradiation therapy followed by surgical resection. Twenty‐eight patients were treated with a regimen (protocol A) of 5‐fluorouracil 750 mg/m 2 on days 1–5 and 22–26, and cisplatin 70 mg/m 2 on days 1 and 22. The remaining 17 patients were treated with a modified regimen (protocol B) of 5‐fluorouracil 400 mg/m 2 and cisplatin 10 mg/m 2 on days 1–5, 8–12, 15–19, and 22–26. Radiation was delivered daily for 5 days/week for 4 weeks at the rate of 2 Gy/day to a total dose of 40 Gy in both protocols. Results A major clinical response was observed in 29 [3 complete response (CR) and 26 partial response (PR)] patients (64.4%). Twenty‐eight patients (62.2%) underwent esophagectomy with no postoperative death. The median survival time of the resected patients (959 days) was significantly longer than that of the non‐resected patients (178 days). Protocol B showed significantly higher pathologic effectiveness than protocol A. The pathologic CR rate for the main tumors was 1 (6.3%) of 16 patients for protocol A and 7 (58.3%) of 12 patients for protocol B. The pathologic CR rate for metastasized lymph nodes was 4/11 (36.4%) for protocol A and 5/5 (100%) for protocol B. Good histological response of the main tumors correlated well with long survival. The treatments were well tolerated except for one treatment‐related death. Conclusions Concurrent chemoradiation therapy followed by surgery is an effective and safe multimodal therapy for patients with primary inoperable T4 SCC of the esophagus. J. Surg.
