Nimotuzumab Combined With Concurrent Chemoradiotherapy for Locally Advanced Treatment Esophageal Cancer in Old Age
In Brief
A Phase 2 clinical trial evaluating Nimotuzumab, S-1, and 1 other intervention for Esophageal Carcinoma. Completed, enrolled 56 participants across 1 site.
Detailed Summary
The research subjects of this project are mainly aimed at patients with locally advanced esophageal cancer who cannot be treated surgically, in nimotuzumab 3 months after the end of concurrent chemoradiotherapy, RECIST is pressed as based on physical examination and esophageal barium dialysis or esophageal contrast-enhanced CT Criteria assessed short-term and long-term efficacy separately. By detecting the expression of EGFR in patients with locally advanced esophageal cancer, the relationship between the efficacy of EGFR monoclonal antibody therapy and the long-term prognosis of patients was evaluated. Evaluation of safety, toxicity and side effects during treatment and in the near and long term.

Timeline
Interventions
Nimotuzumab 400mg plus normal saline 250ml intravenous infusion for not less than 60 minutes. Starting from week 1 of radiotherapy, 1 dose of the same dose each time for a total of 6 doses. The use of nimotuzumab is not interrupted due to interruption of radiotherapy during the administration until the end of radiotherapy.
Oral chemotherapy with the S-1 regimen is given on days 1 to 2 of radiotherapy, with the drug dose calculated based on body surface area, and the oral S-1 course from Monday to Friday is synchronized with radiation therapy.
Outline the target area layer by layer on the enhanced CT image, PGTV, PTV. The endangered organs are delineated layer by layer on the cross-section, and extended 0.3cm to form a corresponding plan to endanger the organs. The reverse intensity modulated radiotherapy plan was designed on the Monaco treatment plan system, with a prescribing dose of 56Gy/30F for PTV and 60Gy/30F for pGTV, and the target dose distribution and organ exposure dose were evaluated layer by layer on a cross-sectional surface, and combined with dose-to-volume histogram (DVH) evaluation and optimal treatment plan, the maximum dose of radiation in the spinal cord \< 40 Gy and lung V20\<30%. After the treatment plan is confirmed, the dose is verified on the treatment machine, and the treatment plan is executed after it is accurate. govern
