Salvage surgery(S-surgery)was performed for residual or relapse tumor after definitive chemoradiotherapy (dCRT)for resectable esophageal cancer. When it becomes possible to perform surgery after dCRT for unresectable cases is called conversion surgery(C-surgery). To examine the outcomes of S-surgery and C-surgery after dCRT for thoracic esophageal cancer and clarify the significance as a multidisciplinary treatment. We reviewed 27 patients who underwent S-surgery for thoracic esophageal cancer in our hospital. 23 cases were residual tumor, 4 were relapse after complete response. Sixteen cases(59%)were C-surgery. Five cases(19%)had non-radical resection. Two cases were postoperative hospital death(7%). Postoperative complications(Clavien-Dindo classification Grade II and more) 11 cases(41%). Four cases were anastomotic leakage, 4 cases vocal cord paralysis, etc. Pathological complete response cases 6 cases(22%). The recurrence cases were 7 except for 5 cases of non-radical resection. Three-year overall survival rate was 47%. Twelve cases(75%)in C-surgery could perform radical resection by down stage. The postoperative hospital mortality and complications can be considered as acceptable. dCRT is a powerful pre-operative treatment for such cases, and S-surgery plays an important role.
