A numerical trend towards a lower risk of ILRR for patients receiving chemotherapy was observed (HR 0.63 95% CI 0.39-1.03; P = .068).

Indeed, extent of nodal involvement at first BC diagnosis was significantly associated with worse DRFI (patients with N3 tumors presented a significantly worse DRFI post-ILRR as compared with those with node-negative disease: HR 5.48, 95% CI 1.16-25.95; P = .032), and patients with larger tumors at first diagnosis showed a trend towards worse DRFI post-ILRR, although not statistically significant (pT4 versus pT1: HR 7.62, 95% CI 0.94-62.02; P = .058) ( Table 3 ).
