The significance of neoadjuvant chemoradiotherapy (NACRT) for esophageal squamous cell carcinoma (ESCC) remains controversial with regard to the pathological response and long-term survival. We herein review the current status of and future perspectives regarding NACRT followed by esophagectomy for locally advanced ESCC. Some studies have suggested that a pathological complete response with NACRT is more common in patients with ESCC than in those with adenocarcinoma and that NACRT provided a survival benefit limited to patients with ESCC. However, NACRT may increase the risk of postoperative complications after esophagectomy. It is obvious that a favorable pathological response is the most important factor for obtaining a survival benefit, although no established parameters have been implemented clinically to predict the response to NACRT. Prospective clinical studies and basic research studies to identify predictive biomarkers for the response to NACRT are needed to aid in the development of NACRT treatment strategies for patients with ESCC.
新辅助放化疗(NACRT)对食管鳞状细胞癌(ESCC)的意义在病理反应和长期生存方面仍存在争议。我们在此回顾了NACRT联合食管切除术治疗局部晚期ESCC的现状及未来展望。一些研究表明,NACRT后病理完全缓解在ESCC患者中比在腺癌患者中更常见,且NACRT带来的生存获益仅限于ESCC患者。然而,NACRT可能会增加食管切除术后并发症的风险。显然,良好的病理反应是获得生存获益的最重要因素,尽管目前尚无已在临床上实施的既定参数来预测对NACRT的反应。需要开展前瞻性临床研究和基础研究以确定NACRT反应的预测生物标志物,以助力ESCC患者NACRT治疗策略的制定。
