BACKGROUND: Among patients with T4 thoracic esophageal squamous cell carcinoma (TESCC), it is unclear whether the outcomes of late responders who undergo high-dose chemoradiotherapy (CRT) followed by salvage esophagectomy differs from those of early responders who undergo low-dose CRT followed by esophagectomy. METHODS: A total of 153 patients with T4 TESCC were treated with CRT. The first evaluation was performed after 40 Gy of CRT for downstaging. Of these, 28 patients could be downstaged, and underwent subsequent surgery (early responders). For the remaining patients, additional CRT was administered, and patients were re-evaluated after treatment and underwent salvage surgery. In total, 40 patients (early + late responders) were analyzed. RESULTS: The primary tumors exhibited a grade 3 response in six (21.4 %) of the early responders and two (16.7 %) of the late responders (p = 1.000). The rate of residual tumor in the primary tumor was 80 % (32/40 patients). The proportions of resected lymph nodes and positive metastatic nodes were similar between early and late responders (p = 0.406 and p = 0.859, respectively). The 5-year overall survival rates among the early and late responders were 25.9 and 36.5 %, respectively, and the median survival times were 24.8 and 24.3 months (p = 0.925), respectively. The 5-year cause-specific survival rates in the early and late responder groups were 61.5 and 72.9 % (p = 0.425), respectively. CONCLUSION: The outcomes of both early and late responders to CRT were similar, and salvage surgery for T4 TESCC outweighs the risks in patients with T4 TESCC.
