Of the 3543 stage III CRC patients included, 1091 had TD (30.8%). Of these, 884 had TD and LNM (25.0%), whereas 207 had TD alone (5.8%). Patients with TD and LNM had significantly poorer survival than those with LNM alone (5-year OS 52.2% versus 69.2%; P &amp;lt; 0.001). On subgroup analyses, the presence of TD was associated with poorer OS across all N categories. On multivariable analysis, TD was independently associated with all-cause mortality (hazard ratio 1.25; 95% confidence interval 1.08 to 1.43; P = 0.002). Patients with TD only were significantly less likely to receive adjuvant chemotherapy than those with LNM or TD and LNM (42.5% versus 52.2% and 55.9%, respectively; P = 0.002).<\/jats:p>\n
