Abstract Purpose The aim of the study was to evaluate the prognostic value of free fatty acid (FFA) and high-density lipoprotein cholesterol (HDL-C) in predicting colorectal neuroendocrine tumours (NETs). Methods One hundred patients with pathologically diagnosed colorectal NETs in 2011-2017 were enrolled, and the levels of FFA, HDL-C, low-density lipoproteincholesterol (LDL-C), triglycerides (TGs), cholesterol (CHOL), apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) between colorectal NET patients and healthy controls matched by age and sex were compared. In addition, the association of clinicopathological characteristics and follow-up data with FFA and HDL-C was analysed. Results FFA was overexpressed (0.55±0.23 vs. 0.48±0.11, P= 0.006) and HDL-C was underexpressed (1.31±0.41 vs. 1.41±0.29, P=0.046) in colorectal NETs. FFA ≥0.52 mmol/L predicted lymph node metastasis (LNM) (χ2 = 5.964, P=0.015), and HDL-C ≤1.0 mmol/L predicted tumour size ≥2 cm (χ2 = 5.647, P=0.017). No significant association was found between FFA and tumour size (P=0.142) or HDL-C and LNM (P=0.443). FFA ≥0.52 mmol/L (χ2 = 6.016, P=0.014) and HDL-C ≤1.0 mmol/L predicted worse overall survival (OS) (χ2 = 5.488, P=0.019). FFA ≥0.52 mmol/L in combination with HDL-C ≤1.0 mmol/L predicted an even worse prognosis in terms of OS (χ2 = 4.818, P=0.028). Conclusion FFA ≥0.52 mmol/L and HDL-C ≤1.0 mmol/L were promising cut-off values in predicting LNM, tumour size and worse OS in colorectal NETs.

Abstract Background: free fatty acids (FFAs) and high-density lipoprotein cholesterol (HDL-C) were associated with various malignancy. However, whether FFA, HDL-C and FFA/HDL-C can play a potiential role in predicting patients with colorectal neuroendocrine tumours (NETs) was unclear. Meanwhile, FFA/HDL-C has a superior prognosis ability was unknown, too.Methods: One hundred patients with pathologically diagnosed colorectal NETs in 2011-2017 were enrolled, and the levels of FFA, HDL-C, low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), cholesterol (CHOL), apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) between colorectal NET patients and healthy controls matched by age and sex were compared. In addition, the association of clinicopathological characteristics and follow-up data with FFA, HDL-C and FFA/HDL-C was analysed.Results: FFA was overexpressed (0.55±0.23 vs. 0.48±0.11, P= 0.006), and HDL-C was underexpressed (1.31±0.41 vs. 1.41±0.29, P=0.046) in colorectal NETs. FFA ≥0.52 mmol/L predicted lymph node metastasis (LNM) (P=0.015), HDL-C ≤1.0 mmol/L predicted tumour size ≥2 cm (P=0.017), and FFA/HDL-C>0.75 predicted tumour grade (P=0.030), LNM (P=0.014), and tumour size(P=0.018). No significant association was found between FFA and tumour grade (P=0.613) or HDL-C and tumour grade (P=0.594) or FFA and tumour size (P=0.142) or HDL-C and LNM (P=0.443). FFA ≥0.52 mmol/L (P=0.014) and HDL-C ≤1.0 mmol/L predicted worse overall survival (OS) (P=0.019). FFA/HDL-C predicted an even worse prognosis in terms of OS (P<0.001).Conclusion: FFA ≥0.52 mmol/L HDL-C ≤1.0 mmol/L and FFA/HDL-C>0.75 were promising cut-off values in predicting LNM, tumour size and worse OS in colorectal NETs.

The effect of combining omega-3 fatty acid (n-3 FA) supplementation and exercise training treatment on postprandial lipemia (PPL) has not been studied. The purpose of this study was to examine the interaction of n-3 FA and exercise training in attenuating PPL after a high-fat meal. Previously sedentary, overweight, subjects (n = 22; 12 women, 10 men, BMI 26.6 ±0.7 kg/m2) were randomly assigned to one of two treatment groups: n-3 FA supplementation alone (FO, n = 10) or n-3 FA supplementation plus exercise training (FO+ExTr, n = 12). Both groups consumed 4 g/d n-3 FA, and one group also exercise trained for 45 min/d, 5d/week of brisk walking and (or) jogging at 60% VO2 max. Before and after 4 weeks of treatment, subjects performed a baseline PPL and a PPL following a single session of exercise (ExPPL). PPL was assessed by triglyceride (TG) area under the curve (AUC) and peak TG response (TGpeak). A two-way analysis of variance (ANOVA) with repeated measures was used to compare results from treatments for baseline and exercise trials. FO alone reduced PPL and Ex PPL, and FO+ExTr attenuated the ExPPL response measured as total AUC and TGpeak. There was no significant main effect for group or group by time interaction for baseline PPL or ExPPL. Fasting high-density lipoprotein cholesterol (HDL-C) and HDL2-C (i.e., subfraction 2) concentrations were significantly increased in the FO+ExTr group after the treatments. These results suggest that n-3 FA supplementation reduced PPL in sedentary subjects. Exercise training has no interference or additive effects with n-3 FA supplementation in attenuating PPL, but combined treatments may be additive in raising high-density lipoprotein cholesterol.
