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.

Background: Resistance to endocrine therapy has been a major obstacle in the management of hormone receptor (HR)-positive metastatic breast cancer (MBC). Meanwhile, a number of treatments are available to such patients, and physicians often encounter difficulties in choosing the most appropriate treatments for individual patients. The combination of CDK 4/6 inhibitors (CDKi) and endocrine therapy has now become a standard treatment for HR-positive and human epidermal growth factor receptor 2 (HER2)-negative MBC. However, no predictive markers for CDKi-based treatments have been established. Considering their side effects and the financial burden on patients, identifying such markers is crucial. Methods: Clinicopathological features of 107 patients with HR-positive HER2-negative MBC, who received CDKi-based treatments at our institution were retrospectively investigated. HR status in distant metastatic lesions and immunocompetent cells in peripheral blood were also studied. Results: Progression-free survival (PFS) was significantly shorter in patients whose primary tumour was high grade ( P = 0.016) or high neutrophil-to-lymphocyte ratio (NLR) at baseline ( P = 0.017). Meanwhile, there were no differences in other factors, such as expression levels of hormone receptors. Patients whose metastatic lesions were of low tumour grade or high Ki67 labelling index had longer PFS, and such trends were more obvious than primary lesions. Conclusion: Our data indicate that tumour grade in primary lesion and NLR are potential predictive factors for CDKi-based treatments. Moreover, pathological assessment of metastatic lesions might also be useful.

Objectives: The aim of this exploratory study was to evaluate whether three-dimensional texture analysis (3D-TA) features of non-contrast-enhanced T1-weighted MRI associate with traditional prognostic factors and disease-free survival (DFS) of breast cancer. Methods: 3D-T1-weighted images from 78 patients with 81 malignant histopathologically verified breast lesions were retrospectively analysed using standard-size volumes of interest. Grey-level co-occurrence matrix (GLCM) based features were selected for statistical analysis. In statistics the Mann–Whitney U and the Kruskal–Wallis tests, the Cox proportional hazards model and the Kaplan-Meier method were used. Results: Tumours with higher histological grade were significantly associated with higher contrast (1voxel: p = 0.033, two voxels: p = 0.036). All the entropy parameters showed significant correlation with tumour grade (p = 0.015–0.050) but there were no statistically significant associations between other TA parameters and tumour grade. The Nottingham Prognostic Index (NPI) was correlated with contrast and sum entropy parameters. A higher sum variance TA parameter was a significant predictor of shorter DFS. Conclusion: Texture parameters, assessed by 3D-TA from non-enhanced T1-weighted images, indicate tumour heterogeneity but have limited independent prognostic value. However, they are associated with tumour grade, NPI, and DFS. These parameters could be used as an adjunct to contrast-enhanced TA parameters. Advances in knowledge: 3D texture analysis of non-contrast enhanced T1-weighted breast MRI associates with tumour grade, NPI, and DFS. The use of non-contrast 3D TA parameters in adjunct with contrast-enhanced 3D TA parameters warrants further research.

Background: Laparoscopic surgery produces lesser postoperative inflammation with a smaller cytokine and leptin response, and might thus reduce postoperative anorexia compared with open surgery. The aim of the present study was to determine the role of serum leptin in postoperative anorexia after laparoscopic gastric cancer surgery. Methods: Fifty-four consecutive patients with adenocarcinoma of the stomach were operated on either with open or laparoscopic surgery. Correlations were determined between the serum levels of leptin, clinico-pathological characteristics, serum haemoglobin, and albumin. Results: Serum leptin levels on day seven were correlated significantly to gender (p = 0.004), body mass index (BMI) (p = 0.002), and tumour grade (p = 0.033). In the patients with C-reactive protein (CRP) < 100 mg/L (n = 46) the leptin levels on day seven were significantly lower after the laparoscopic operation (p = 0.042) and in patients with lower BMI (p = 0.001). The linear regression model determined a significant correlation between the relative concentration of leptin on day seven and laparoscopic surgery (Beta−0.688; p < 0.0001), gender, BMI, location of the tumour, T stage, N stage, perioperative therapy, tumour grade, perineural invasion, Lauren histological type, and ulceration. In patients with CRP levels below 100 mg/mL, the serum level of albumin on day seven after surgery was significantly higher in patients after laparoscopic surgery. Conclusion: Laparoscopic surgery produced significantly lower relative leptin concentrations on day seven, and higher serum albumin levels in the subgroup with CRP levels below 100 mg/L at discharge. These results suggested that laparoscopic gastric cancer surgery might reduce postoperative leptin response, leading to a better nutritional status at discharge compared with open surgery.

Abstract BackroundSeveral hematological markers of systemic inflammation were reported as prognostic in renal cell carcinoma (RCC). We aimed to re-evaluate the prognostic significance of clinicopathologic features and compare the predictive value of different inflammatory markers in RCC.MethodsFour hundred ninety-five patients treated with nephrectomy for primary localized or locally advanced RCC were included in the retrospective analysis. The median follow-up was 48 months.ResultsPatients with higher neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), systemic inflammatory response index (SIRI), systemic immune-inflammation index (SII), neutrophil/erythrocyte ratio (NER), derived neutrophil/lymphocyte ratio (dNLR), and lower lymphocyte/monocyte ratio (LMR) and hemoglobin/platelet ratio (HPR) had worse cancer-specific survival (CSS). In the multivariate analysis tumour stage, grade, age and high SIRI constituted independent factors predicting CSS. The model including SIRI values achieved C-index 0.903. Alternative multivariate models that included SII and NLR were characterized by comparable C-indexes i.e. 0.902 and 0.890, respectively. Different inflammatory markers could not be utilized in a single model, as they show a strong correlation with one other (SII, SIRI and NLR), and seem to provide similar prognostic information. Tumour grade and diameter were independent predictors for recurrence-free survival, whereas age, tumour grade and high NER (or high SIRI/ SII in alternative models) were prognostic for overall survival.ConclusionsMarkers of systemic inflammation might provide additional prognostic information (especially SIRI, SII, NLR and NER) and further increase the predictive accuracy of already available models in localized and locally advanced renal cell carcinoma. Clinicopathological features (stage, grade and age) remain the most important prognostic factors for oncological outcomes in RCC patients treated with nephrectomy. For the first time, we show the prognostic value of neutrophil-to-erythrocyte ratio, which constitutes an independent risk factor of overall survival.Trial registrationnot applicable

Background: Duodenal neuroendocrine tumours (D-NETs) are rare but increasingly diagnosed. This study aimed to assess the overall survival and recurrence rate among patients treated for D-NETs. Methods: Patients with D-NETs were retrospectively reviewed with a median follow-up time of 4.8 years (range 0.0–17.2 years). Results: A total of 32 patients with median age 68.0 years were identified. Fifteen patients underwent surgery while ten patients underwent endoscopic treatment. Mean estimated overall survival for the entire population was 12.1 years (95% CI 9.5–14.7 years), while 5-year overall survival was 81.3%. Tumour grade G1 was associated with longer mean estimated survival compared to G2 tumours (13.2 years versus 4.4 years, p = 0.010). None of the 23 patients who underwent presumed radical endoscopic or surgical resection had disease recurrence during follow-up. Tumours <10 mm could be treated endoscopically whereas a high proportion of patients with tumours 10–20 mm should be considered for surgery. Conclusion: Patients with D-NETs had long overall survival, and mortality was more influenced by other diseases. Both endoscopic and surgical resections were effective as no recurrences were diagnosed during follow-up.
