Does neoadjuvant chemoradiotherapy for esophageal and gastroesophageal junction cancer patients affect postoperative outcomes? a study using the becker tumor regression grade system and lymph node regression.

In our series, we were unable to demonstrate an association between Becker tumor regression grade and lymph node regression rate with any postoperative complications. Patients with lower lymphatic permeation and vascular invasion have higher overall survival, correlating with a better response in the Becker tumor regression grade system.
