    Abstract:
    BACKGROUND AND OBJECTIVES: Although salvage surgery after definitive chemoradiotherapy (CRT) is common, the safety and indication has not yet been established. METHODS: We retrospectively compared the mortality and morbidity of 24 patients who underwent salvage surgery with those of historical controls treated with neoadjuvant CRT followed by planned esophagectomy during the same period, and analyzed the prognostic factor of salvage surgery. RESULTS: Preoperative serum albumin (3.7 vs. 4.1 g/dl, P = 0.0157) and lymphocyte count (763 vs. 964/mm(3), P = 0.0111) in the salvage group were significantly lower than those in the neoadjuvant group. A significant difference was also observed in operation time (567 vs. 474 min, P = 0.0381), C-reactive protein (CRP) on postoperative day 1 (11.2 vs. 8.7 mg/dl, P = 0.0021), and postoperative systemic inflammatory response syndrome (SIRS) duration (3.5 vs. 2.9 days, P = 0.0486). There were three hospital deaths in the salvage group, whereas no patient died in the neoadjuvant group. Multivariate analysis showed curability (R0 vs. R1 + R2) to be the strongest prognostic factor of salvage surgery (P = 0.0064). R1 + R2 operation was more frequently performed in the salvage group (33% vs. 13%), and the reason for all cases was unresectable T4, which had been underestimated preoperatively. CONCLUSIONS: Salvage surgery is a highly invasive and morbid operation, which is performed on immunocompromised hosts. The indication must be carefully considered, with care taken to avoid non-curative surgery.
