Diagnostic value of the preoperative platelet/lymphocyte ratio and red cell distribution volume in patients with renal masses.

OBJECTIVES: Inflammatory markers indicate immune system responses. BACKGROUND: We retrospectively explored whether the platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), and red blood cell distribution width (RDW) were predictive of malignant disease. MATERIAL AND METHODS: Between 2019 and 2023, 148 patients diagnosed with malignant and benign renal tumors via imaging or biopsy were included. Of these tumors, 117 were malignant and 31 were benign. Blood samples were taken for calculation of the NLR, PLR, and RDW prior to renal biopsy or operation. RESULTS: The NLR, PLR, and RDW did not differ significantly between patients with malignant and benign renal masses (all p > 0.05). The PLR significantly increased with the T stage of malignant masses (p = 0.011). According to the T stage, the RDW cutoff was 45.7, the sensitivity was 40 %, and the specificity 82.4 %; the respective values for PLR were 134.9, 70 %, and 70.5 % (p = 0.026 and p = 0.003, respectively). CONCLUSION: The NLR, PLR, and RDW were not predictive in this study because we only included early- stage patients lacking lymph node involvement and the follow-up was short. In patients with renal cell carcinomas, the RDW and PLR increase with the tumor burden and predict poor prognosis (Tab. 5, Fig. 1, Ref. 23).

Prediabetes and Type 2 Diabetes are Independent Risk Factors for Computed Tomography-Estimated Nonalcoholic Fatty Pancreas Disease.

OBJECTIVES: Nonalcoholic fatty pancreas disease (NAFPD) is characterized by excessive fat deposition in the pancreas in the absence of alcohol consumption. In this study, we aimed to detect a possible relationship between adipose tissue accumulation, prediabetes and diabetes. METHODS: This cross-sectional and retrospective study included 110 patients. Three groups were classified as controls, patients with prediabetes and patients with type 2 diabetes. The abdominal computed tomography (CT) attenuation measurement results of the pancreas were evaluated independently by two experienced radiologists. CT measurements and biochemical parameters were compared between study groups. The relationship between continuous variables was assessed by using one-way ANOVA. To determine the changes in the dependent variable for the effects on study groups, the independent variable was adjusted using ANCOVA. A p-value less than 0.05 was considered statistically significant. RESULTS: The presence of prediabetes and type 2 diabetes was correlated with a decrease in the mean Hounsfield Unit (HU) value of the pancreas (p=0.002). Age was determined to be an independent risk factor and was correlated with NAFPD (p=0.0001). When compared to the controls (p=0.041), 71% of patients with prediabetes and 67% of patients with type 2 diabetes were observed to have an increased incidence of NAFPD. Decreased serum amylase was found to be correlated with the mean HU value of the pancreas (p=0.043). CONCLUSION: NAFPD was independently correlated with both prediabetes and type 2 diabetes adjusted for age (p=0.0001) in this study. Additionally, age was determined to be an independent risk factor and was correlated with NAFPD.
