Prognostic Classification of Histopathologic Response to Neoadjuvant Therapy in Esophageal Adenocarcinoma [1]
The histologic response to induction therapy is usually a binary function. In the current study, the authors explored methods of refining the histologic response classification to improve prediction of prognosis for patients with esophageal adenocarcinoma. They identified 3 unique groups: major response in the primary tumor with ypN0; either major response with ypN+ or minor response with ypN0; minor response and ypN+. The 5-yr survivals were 64%, 42%, and 18%, respectively.
