Postoperative Radiotherapy in Pathological T2-3N0M0 Thoracic Esophageal Squamous Cell Carcinoma: Interim Report of a Prospective, Phase III, Randomized Controlled Study.

ABSTRACT:

Background

The role of postoperative radiotherapy in pathological T2-3N0M0 esophageal squamous cell carcinoma is unknown. We aimed to evaluate the efficacy and safety of postoperative radiotherapy in patients with pathological T2-3N0M0 thoracic esophageal squamous cell carcinoma.

Materials and methods

Patients aged 18-72 years with pathological stage T2-3N0M0 esophageal squamous cell carcinoma after radical surgery and without neoadjuvant therapy were eligible. Patients were randomly assigned to surgery alone or to receive postoperative radiotherapy of 50.4 Gy in supraclavicular field and 56 Gy in mediastinal field in 28 fractions over 6 weeks. The primary endpoint was disease-free survival. The secondary endpoints were local-regional recurrence rate, overall survival, and r
