Table 2 Peri-tumoural monounsaturated, polyunsaturated and saturated fatty acids (MUFA, PUFA, SFA) mean, skewness, entropy and kurtosis were compared between molecular subtypes and in tubule formation Scores 2 and 3. The Spearman’s rank correlation coefficients (ρ) between lipid constituents against proliferative activity marker Ki-67 and tumour-infiltrating lymphocytes (TILs) are also shown. Statistical significant differences (p < 0.05) are marked by ‘*’
