Fig. 3From: Dentate line invasion as a predictive factor of poor distant relapse-free survival in locally advanced lower rectal cancer with anal sphincter involvementForest plot of HRs for DLI versus non-DLI of LALRC with anal sphincter involvement in the subgroup analysis of distant relapse-free survival. Abbreviations: HRs = hazard ratios, DLI = dentate line invasion, DRFS = distant relapse-free survival, LALRC = locally advanced lower rectal cancer, CEA = carcinoembryonic antigen, c = clinical, ECOG = Eastern Cooperative Oncology Group. *Evaluated by pretreatment diagnostic biopsy. Low indicates well or moderately differentiated; high indicates poorly differentiated, mucinous, or signet ring cell carcinomaBack to article page
