Resection margin status showed a marginal trend with TSR in the overall cohort ( p = 0.058): margin-negative resections were 35/37 (94.6%) in the TSR < 13% group versus 37/47 (78.7%) in the TSR ≥13% group.

The distribution of pT category approached significance ( p = 0.060); the NAC cohort included more pT1 and fewer pT2, with a modest excess of pT3 (NAC: pT1 13/35, 37.1%; pT2 13/35, 37.1%; pT3 9/35, 25.7% vs.
In multivariate models, β-CTN/m-CK index < 0.5 (HR 2.230, 95% CI 1.106–4.500; p = 0.025) was the independent predictor of shorter RFS, and TSR ≥ 13% showed marginal significance for CSS (HR 2.536, 95% CI 0.947–6.790; p = 0.064).
