of borderline significancep = 0.051
A positive correlation of borderline significance ( r = 0.39; p = 0.051) was found between baseline‐to‐follow‐up changes in serum TNFα and tumor cell Ki67, though correlations between TNFα in the sera and TNFα tumor staining, as well as TNFα tumor staining and Ki67 were nonsignificant ( p ‐values ranging between 0.50 and 0.58).
