MKI67 and neoplasm: Additionally, no correlation was observed between baseline-CFD and CA15-3 or Ki-67 levels (CA15-3, <20 U/mL vs. ≥20 U/mL; P = 0.227 and Ki-67, 0%–20% vs. 30%–100%; P-value=0.580), where as statistically significant differences were observed between baseline-CFD and tumor-infiltrating lymphocyte (TIL) levels (TILs, ≤40% vs. >40%; P = 0.027; Table 2).
