The overall progression rate was 49.3% (Table Characteristics and time to the progression.Abbreviations: CI, confidence interval; ENE, extranodal extension; Sig, log rank (Mantel‐Cox) significance; TD, tumor deposit.The OS rate at 3 years was 55.7% for the whole study group, 60.4% in ENE, and 38.4% in TDs (Kaplan–Meier plots. Overall Survival and differences between extranodal extension (ENE) and tumor deposits (TDs) groups.Overall survival in ENE and TDs.Abbreviations: CI, confidence interval; ENE, extranodal extension; HR, hazard ratio; OS, overall survival; Kaplan–Meier plots. Overall survival (OS) for groups with extranodal extension (ENE) in pN2a, pN3b, and tumor deposits (TDs).In order to assess the impact of patients with both ENE and TDs on our findings, a sensitivity analysis was performed by excluding six patients from the study. After their exclusion, the univariate Cox regression analysis still yielded significant results for ENE/TDs (Exp (B) 0.439, 95% CI 0.196–0.982;
