Summary

The purpose of this study is to observe and evaluate the efficacy and safety of pembrolizumab plus paclitaxel, cisplatin followed by Da Vinci robot radical surgery for locally advanced esophageal squamous cell carcinoma.

Detailed description

The Preoperative chemoradiotherapy with surgery is the standard treatment in NCCN guideline. But many patients refused or abandon radiotherapy because of the intolerable adverse effects. We designed a single-arm, open-label, phase II trial of pembrolizumab plus paclitaxel, cisplatin followed by Da Vinci robot radical surgery for locally advanced (stage III) esophageal squamous cell cancer. The purpose of this study is to observe and evaluate the efficacy and safety.

Conditions

• Esophageal Squamous Cell Carcinoma
• Stage III

Interventions

Type	Name	Description
DRUG	Pembrolizumab Injection [Keytruda]	Neoadjuvant period:preoperative therapy with three cycles: Pembrolizumab 200mg D1; Paclitaxel 135mg/m2 D2; Cisplatin 20mg/m2 D2-D4; repeated every 3 weeks. Da Vinci robot radical surgery: Before surgery, head/abdomen/chest CT scan, type B ultrasonic, upper gastrointestinal contrast, endoscopic ultrasound (EUS), and gastroscopy with biopsy will be done. Surgery should be done within 4-6 weeks after last neoadjuvant treatment finished. Adjuvant period: Adjuvant treatment with pembrolizumab 200mg every 3 weeks (6 cycles) should be performed within 3-6 weeks after surgery if the surgical pathology result is not pCR. abdomen/chest CT scan will be performed every 3 month after surgery.
