In recent years, neoadjuvant chemoradiotherapy (NCRT) combined with surgery has been gradually applied in patients with locally advanced thoracic esophageal cancer, but its effectiveness and safety remains unclear. In this clinical trial, we prospectively investigated the efficacy and safety of NCRT plus surgery in the treatment of thoracic esophageal squamous cell carcinoma (TESCC).

To investigate the efficacy and safety of NCRT combined with surgery in the treatment of potentially resectable TESCC.

Thirty patients with advanced TESCC hospitalized in our hospital from July 2016 to June 2019 were prospectively studied. All patients received NCRT, which included intensity modulated conformal radiotherapy (40-44 Gy/20-22f, 2 Gy/f) and chemotherapy (paclitaxel 150-175 mg/m²d1, 22 + lobaplatin 25-30 mg/m²d2, 23 for two cycles). Surgery was performed after radiotherapy and chemotherapy. The effectiveness and safety of these treatments were observed.

Among these 30 patients, complete response was achieved in two cases (6.7%) and partial response in 26 cases (86.7%), yielding an objective response rate of 100%. All patients underwent radical surgery successfully. The R0 resection rate was 100%, and the pathologic complete response rate was 33.3%. The incidence of grade III- IV granulocytopenia was 10% during the NCRT, and anastomotic leakage occurred in one patient after surgery.

For patients with potentially resectable TESCC, NCRT can effectively reduce the tumor size, increase R0 resection rate, and achieve obvious pathological degradation, with mild adverse reactions. Thus, it is worthy of wider clinical application.
