Two-field Versus Three-field Lymph Node Dissection in ESCC After Neoadjuvant Therapy
Two-field Versus Three-field Lymph Node Dissection for Esophageal Squamous Cell Carcinoma Patients Without Cervical Lymph Node Metastasis After Neoadjuvant Therapy: A Multi-center, Prospective Randomized Controlled Study
Study Overview

Detailed Description
In locally advanced esophageal squamous cell carcinoma patients, neoadjuvant therapy has become a standard therapeutic strategy and been widely administered. Neoadjuvant therapy drastically reduces the metastatic lymph nodes rate as verified in numerous studies including CROSS (Netherlands), JCOG9907/1109 (Japan), NEOCRTEC5010 and CMISG1701 (China) trials, which entails a study to characterize the distribution of lymph node metastasis, and to identify the optimal extent of lymphadenectomy in ESCC patients who received neoadjuvant therapy.
This study aims to clarify whether three-field (cervical-thoracic-abdominal) lymphadenectomy will improve survival over two-field (thoracic-abdominal) lymphadenectomy for ESCC patients after neoadjuvant therapy.
An estimated 323 patients will be enrolled. Eligible patients will undergo right recurrent laryngeal nerve lymph node dissection (106recR), which will be subjected to intra-operative frozen resection pathological evaluation. If 106recR lymph node reports POSITIVE, patients will undergo esophagectomy with Three-Field lymphadenectomy (n=75). If 106recR lymph node reports NEGATIVE, patients will be randomized at 1:1 ratio into two groups: A) Esophagectomy with Two-Field lymphadenectomy (n=124) or B) Esophagectomy with Three-Field lymphadenectomy (n=124). Analyses will be done according to the intention-to-treat principle.
The primary end point is overall survival (OS), calculated from the date of randomization to the date of death from any cause. Secondary end point is Disease-free survival. Other exploratory end points include tumor recurrence pattern, quality of life, peri-operative complications, and the correlation between metastases of 106recR and cervical lymph nodes.

Description
Inclusion Criteria:
- Squamous cell carcinoma was diagnosed by the pathological type of gastroscopic biopsy;
- The primary tumor is located in the thoracic, and the primary site of esophageal cancer is determined by the location of the esophagus where the upper edge of the mass is located (upper thoracic esophagus: from the entrance of the thoracic cavity, down to the level of the lower edge of the azygos vein arch, 20 cm from the incisors to the endoscopy <25 cm; middle thoracic esophagus: from the lower border of the azygos vein arch, down to the level of the inferior pulmonary vein, 25 cm to 30 cm from the incisors on endoscopy; lower thoracic esophagus: from the level of the inferior pulmonary veins, down to the stomach, internal Endoscopy 30 cm to 40 cm from the incisors);
