ASO Perspectives: Adjuvant Nivolumab in Resected Esophageal or Gastroesophageal Junction Cancer: Never Stop Questioning.

The use of postoperative immunotherapy represents a significant paradigm shift for managing patients who have had limited evidence-based treatment options after completing neoadjuvant chemoradiation followed by resection for these aggressive malignancies.
