Study Population

Patients with ESCC undergoing nCRT at the Department of Thoracic Surgery, Zhongshan Hospital of Fudan University (training cohort), and the Department of Thoracic Surgery, Zhongshan Hospital Xiamen Branch (validation cohort), between January 2010 and February 2019 were reviewed. The inclusion criteria were (I) thoracic ESCC; (II) McKeown or Ivor-Lewis transthoracic approach; (III) locally advanced resectable tumor with cT3-4aNany staging treated with nCRT; (IV) no history of concomitant or prior malignancy.

You may qualify if:

  • \- Neoadjuvant chemoradiotherapy and surgical resection of esophageal squamous cell carcinoma

You may not qualify if:

  • Patients receiving neoadjuvant chemoradiotherapy for esophageal squamous cell carcinoma without surgical resection
