OBJECTIVE: Tumor regression grading (TRG) systems categorize residual tumor volume on the primary tumor after neoadjuvant treatment. Aim was to evaluate the impact of Mandard TRG, residual tumor depth (ypT) and residual lymph node status (ypN) and extent (ELNI) i.e. intracapsular versus extracapsular involvement on overall (OS) and disease-free survival (DFS) in esophageal carcinoma. METHODS: Between 2005 and 2014, 344 patients receiving R0-esophagectomy after neoadjuvant chemoradiation therapy (nCRT) were selected. Mandard TRG, ypTN and ELNI were prospectively recorded. RESULTS: Mandard TRG1 was found in 110 (32%); TRG2 in 120 (35%); TRG3 in 53 (15%); TRG4 in 54 (16%) and TRG5 in 7 (2%) patients. Both OS and DFS showed no significant difference between TRG1 and 2 (p = 0.059 and 0.105, respectively). Therefore, TRG1/2 was classified together as 'major response', TRG3/4 as 'minor response' and TRG5 as 'no response'. Multivariate analysis showed two independent prognosticators for OS (tumor regression response (TRR) and number of positive lymph nodes) and three independent prognosticators for DFS (TRR, ypT and ELNI). CONCLUSION: After nCRT followed by surgery for esophageal carcinoma, number of residual positive lymph nodes as well as TRR are prognosticators for OS. Minor TRR, ypT and extracapsular lymph node invasion are prognosticators for recurrence.
