Complete response after neoadjuvant therapy for esophageal cancer : Implications for surgery

Chirurg. 2021 Oct 1. doi: 10.1007/s00104-021-01509-3. Online ahead of print.ABSTRACTA relevant number of patients with locally advanced esophageal squamous cell carcinoma and adenocarcinoma show a locoregional complete response of the tumor in the resected material after neoadjuvant therapy with modern chemotherapy and chemoradiation protocols. Due to a high rate of perioperative morbidity and decreased long-term quality of life following esophagectomy, the current treatment algorithm with neoadjuvant therapy and post-neoadjuvant esophagectomy on principle is critically questioned. An individualized treatment algorithm with extended clinical evaluation of post-neoadjuvant remission status and esophagectomy as needed is discussed. Patients with complete remission after neoadjuvant therapy are identified in an extended restaging protocol. Cases of clinical complete remission are treated with an active surveillance concept with esophagectomy as needed, i.e. surgery only when a local tumor recurrence is detected. Retrospective cohort studies have suggested that the active surveillance concept with esophagectomy as needed does not lead to a deterioration of overall survival rates in the patient collective. European prospective randomized, controlled, noninferiority studies with an oncological endpoint are currently evaluating the possibilities of organ-preserving concepts for clinical complete remission of esophageal cancer.PMID:34596707 | DOI:10.1007/s00104-021-01509-3
