Test grouping:~Group A: radical chemoradiotherapy group; Group B: radical chemoradiotherapy combined with consolidation chemotherapy group;~Specific chemotherapy regimens:~Concurrent chemotherapy (2 courses): Lipusu (T) + Cisplatin (DDP) scheme: T 135mg/m2 ivgtt, d1, 3week*2cycles; DDP 75mg/m2 ivgtt, d2, 3week*2cycles; Consolidation chemotherapy (4 courses): After the concurrent chemoradiotherapy is over, after 2-3 weeks of rest, the patients in the consolidation chemotherapy group will be given 4 cycles of consolidation chemotherapy, and the chemotherapy regimen is the same as the concurrent chemotherapy regimen; Radiotherapy scheme: intensity modulated radiotherapy PTV50-54Gy, PGTV 56-60Gy, conventional fractionation.~Primary efficacy endpoints: 3-year overall survival (OS), 5-year overall survival (OS) Secondary efficacy endpoints: 3-year progression-free survival (PFS), 5-year progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), toxic and side effects, and patient quality of life
This study is a phase III, multicenter, prospective randomized controlled clinical study comparing the efficacy of non-surgical esophageal squamous cell carcinoma with radical chemoradiotherapy and radical chemoradiotherapy combined with consolidation chemotherapy. The survival time and side effects of patients were observed and compared.
