Sumario:BACKGROUND: We compared the efficacy, safety, and costs of hypofractionated radiotherapy (HFRT) and conventional fractionated radiotherapy (CFRT) for the neoadjuvant treatment of esophageal cancer. MATERIALS AND METHODS: Overall, 110 patients with esophageal cancer treated with neoadjuvant chemoradiotherapy from October 2002 to July 2017 were retrospectively included and divided into a HFRT group (42 patients received 30 Gray [Gy]/10 fractions for 2 weeks) and a CFRT group [68 patients received 40 Gy/20 fractions for 4 weeks]. Concurrent chemotherapy comprised cisplatin combined with either 5‐FU or taxane. Surgery was performed 3‐8 weeks after radiotherapy. We compared the outcomes, adverse events, and costs between the two groups. RESULTS: Pathological downstaging was achieved in 78.6% of the HFRT group and 83.8% of the CFRT group (P = 0.612). Compared with the CFRT group, the HFRT group had similar pathological complete response (pCR) (33.3% vs 35.3%; P = 0.834), median overall survival (OS) (40.8 months vs 44.9 months; P = 0.772) and progression free survival (32.7 months vs 35.4 months; P = 0.785). The perioperative complication rates were also similar between the groups, but the treatment time and costs were significantly reduced in the HFRT group (P < 0.05). Finally, multivariate analysis identified cN0 stage, pathological downstaging and pCR as independent predictors of better OS. CONCLUSION: Preoperative HFRT is effective and safe for esophageal cancer. Moreover, it is similar to CFRT in terms of overall survival and toxicity and is cost effective and less time consuming.
