Li B, et al. - Researchers investigated if survival is improved by using the right thoracic approach (extended lymphadenectomy) compared with the left thoracic approach (limited lymphadenectomy) for esophageal cancer. The right thoracic approach was observed to be associated with increased disease-free survival and overall survival in esophageal squamous cell carcinoma patients when compared with the left thoracic approach. This was particularly observed in patients with lymph node involvement and/or R1–2 resection margins.
