Neoadjuvant Radiochemotherapy

Neoadjuvant chemoradiotherapy(Neo-CRT) plus surgery has been regarded as a standard of care for patients with resectable locally advanced esophageal cancer. Many studies suggest that definitive Radiochemotherapy(CRT) has similar efficacy as neoadjuvant chemoradiotherapy plus surgery for esophageal cancers who respond to chemoradiation. Herein, a single center prospective randomized phase Ⅲ multicenter clinical trial will be carried out to compare efficacy and safety of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection in patients who achieved clinical complete response (CCR) after neoadjuvant radiochemotherapy for resectable locally advanced esophageal cancer.

1. Compare progression-free survival (PFS) and overall survival (OS) of definitive radiochemotherapy versus(VS) neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete response after neoadjuvant treatment;
2. Compare the toxic and side effects of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete remission after neoadjuvant treatment;
3. Compare the relationship and consistency between pathological complete response of endoscopic biopsy specimens after neoadjuvant treatment and pathological complete response of surgical specimens in neoadjuvant radiochemotherapy plus radical resection group;
4. Assess impact of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection on quality of life of patients.
5. Clinical Complete Response After Neoadjuvant Treatment: Endoscope biopsy pathologic diagnosis indicate pathologic complete response after Neoadjuvant treatment; upper gastrointestinal/chest CT and symptom assessment indicate major response after Neoadjuvant treatment (Concurrent Radiochemotherapy: Radiotherapy, Intensity Modulation Radiation Therapy(IMRT), 40Gy; Chemotherapy, Docetaxel （25mg/m2）+Cisplatin (25mg/m2), 1st/8th/15th/22nd day

A Phase Ⅲ Trial to Compare Efficacy and Safety of Definitive Chemoradiation VS Neoadjuvant Chemoradiation Plus Surgery in Patients Who Achieved Clinical Complete Response After Neoadjuvant Treatment for Locally Advanced Esophageal Cancer

Compare overall survival of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete response after neoadjuvant radiochemotherapy

Compare progression-free survival of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete response after neoadjuvant radiochemotherapy

In the group of neoadjuvant radiochemotherapy plus surgery, we will compare the pathological diagnosis between specimens of endoscopic biopsy after neoadjuvant treatment and surgically resected.

Neoadjuvant chemoradiotherapy(Neo-CRT) plus surgery has been regarded as a standard of care for patients with resectable locally advanced oesophageal cancer. Many studies suggest that definitive Radiochemotherapy(CRT) has similar efficacy as neoadjuvant chemoradiotherapy plus surgery for esophageal cancers who respond to chemoradiation. Herein, a single center prospective randomized phase II clinical trial will be carried out to compare efficacy and safety of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection in patients who achieved clinical complete response(CCR) after neoadjuvant radiochemotherapy for stage II-III esophageal Cancer.

1. Compare progression-free survival (PFS) and overall survival (OS) of definitive radiochemotherapy versus(VS) neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete response after neoadjuvant treatment;
2. Compare the toxic and side effects of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete remission after neoadjuvant treatment;

A Phase II Trial to Compare Efficacy and Safety of Definitive Radiochemotherapy VS Neoadjuvant Radiochemotherapy Plus Surgery in Patients Who Achieved Clinical Complete Response After Neoadjuvant Treatment for Stage II-III Esophageal Cancer

Compare progression-free survival of definitive radiochemotherapy versus neoadjuvant radiochemotherapy plus radical resection for esophageal cancer patients who achieved clinical complete response after neoadjuvant radiochemotherapy.

patients undergo titanium clips placement on tumor boundaries under ultrasonic endoscopy before radiotherapy CT simulation. According to the clips, the reference GTVs are contoured by one experienced radiation oncologist. With the help of Eclipse treatment planning system, clips on CT are concealed. Two other radiation oncologists of expertise in oesophageal cancer delineate GTVs, defined as conventional GTVs, on the basis of endoscopy and oesophageal barium radiography. The two sets of GTVs are compared and analysed.

after titanium clips placement adjacent to esophageal cancer under ultrasonic endoscopy, clips movements in different borders and different directions are observed during radiotherapy simulation to determine the ITV of esophageal cancer, with or without swallowing.
