Preliminary clinical analysis of concurrent chemoradiotherapy combined with nituzumab for inoperable locally advanced esophageal cancer / 中华放射肿瘤学杂志

ABSTRACT

Objective:The standard treatment for inoperable locally advanced esophageal cancer is concurrent chemoradiotherapy, but the survival was not satisfied. Nituzumab is a humanized IgG monoclonal antibody against EGFR. The purpose of this study is to investigate the toxicity and efficacy of concurrent chemoradiotherapy combined with nituzumab for locally advanced esophageal cancer.Methods:We retrospectively reviewed the clinical data of locally advanced esophageal cancer who were treated with concurrent chemoradiotherapy combined with nituzumab in Peking University Cancer Hospital from June 2015 to June 2020. Kaplan- Meier method was used for analysis. Results:Thirty Patients were enrolled this study.After a median follow-up of 22.5 months, The objective response rate was 93%. The 1-year, 2-year, 3-year overall survival rates were 83%, 57% and 41%, with the progression-free survival rates 75%, 47% and 32%, with the local-recurrence free survival rates 83%, 53% and 37%, with the metastasis-free survival rates 75%, 51% and 36%, respectively.The incidence of grade≥3 hematological toxicity was 32%. There were 16% patients experiencing grade≥3 esophagitis.Conclusion:The preliminary result of concurrent chemoradiotherapy combined with nituzumab is effective and safe for patients with locally advanced esophageal cancer.
