HR (−)/HER2-0 BC with high TIL (>10%) levels was not statistically significant in the univariate Cox model; however, after correcting for confounding factors such as age, tumor size, pathological stage, lymph node status, and Ki-67 index, it was statistically significant in the multivariate (HR = 0.16, 95% CI 0.28–0.96, P = 0.045) Cox model. Here, MKI67 is linked to breast cancer.
