Pathologic response in the vitD cohort was significantly associated with HR negative (OR, 0.26; 95% CI, 0.15–0.47), moderate or high tumor grade (OR, 9.64; 95% CI, 1.26–73.93), low levels of Bcl2 (OR, 0.41; 95% CI, 0.22–0.79), and Ki67 >10 (OR, 2.46; 95% CI, 1.13–5.31). Here, BCL2 is linked to neoplasm.
