Neoadjuvant chemotherapy with or without neoadjuvant radiotherapy compared with neoadjuvant chemoradiotherapy for esophageal cancer

摘要

BackgroundAlthough it was controversial for treating locally advanced resectable esophageal squamous cell carcinoma (ESCC), neoadjuvant chemoradiotherapy (NACR) was more widely accepted rather than neoadjuvant chemotherapy (NAC) worldwide. With the development of paclitaxel, a high response rate to NAC was reported in many studies. Our hypothesis is that lots of patients could get a response from NAC alone and avoid unnecessary NACR. Those who had no response from NAC could still response from the followed radiotherapy. We attempted to circumvent the controversy over the use of NAC, NACR and made a combined version, NAC ± neoadjuvant radiotherapy (NAR).
