Problem:Question: Does american Joint Committee on Cancer staging system accurately predict survival in patients receiving multimodality therapy for esophageal adenocarcinoma?
Answer: The current AJCC staging system is not a good predictor of survival after CRT. Although patients with a pCR do have improved long-term survival relative to patients with residual disease, this method places too much emphasis on residual depth of invasion and fails to identify patients with residual disease who have good long-term survival. Recursive partitioning analysis more accurately identifies nodal disease and metastatic disease as the most important prognostic variables. Degree of treatment response is less prognostic than nodal involvement.
Solution:
no
