BMI was slightly different between groups (LR: 22.4 ± 3.0 kg/m 2 , OR: 23.4 ± 2.8 kg/m 2 , P = 0.048, borderline significance), and most patients were ASA II (P = 0.693).

Although the T4a group showed a trend towards lower recurrence rates compared to the T4b group (18.3% vs. 31.4%, P = 0.083), the 3-year OS (81.6% vs. 72.0%, P = 0.596) and DFS (74.4% vs. 55.3%, P = 0.228) were numerically higher in the T4a cohort, though none of these differences reached statistical significance (Table 6 , Fig. 3 ).
