ESR1 and neoplasm: To construct a sophisticated model for pCR prediction after NAC in patients with ER+HER2- LABC, the radiomic texture features of MRI were extracted from the tumor, peritumor 1 mm, peritumor 3 mm, area from tumor-to-peritumor 1 mm, and area from tumor-to-peritumor 3 mm for early post-contrast sequences, delayed post-contrast sequences, and T2-weighted fat-saturated sequences.
