New study identifies specific obesity-related risk factors for kidney cancer

(Spectrum Health) A new study confirms the long-suspected role of obesity as a risk factor for developing renal cell carcinoma (RCC), a type of kidney cancer, and identifies several specific obesity-related factors. These factors include multiple measures of obesity, diastolic blood pressure and fasting insulin. In contrast, the study found little evidence for an association with RCC risk for systolic blood pressure, circulating lipids, diabetes or fasting glucose.

Summary: As early detection and advances in the treatment for renal cell carcinoma continue to lead to excellent oncologic outcomes, the preservation of renal function in kidney cancer patients has emerged as an increasingly important clinical objective. Given that diabetes, hypertension, obesity, cigarette smoking, and aging are independent risk factors for renal cell carcinoma, the corresponding non-neoplastic kidney diseases frequently are present, but often undiagnosed. In addition, the subsequent clinical management of the ensuing chronic kidney disease historically has not included nephrologists.

Authors: Wong ECL, Breau RH, Mallick R, Wood L, Pouliot F, Basappa NS, Tanguay S, Soulières D, So A, Heng D, Lavallée LT, Drachenberg D, Kapoor A Abstract Background: Diagnosis and treatment of renal cell carcinoma (rcc) might be different in Indigenous Canadians than in non-Indigenous Canadians. In this cohort study, we compared rcc presentation and treatments in Indigenous and non-Indigenous Canadians. Methods: Patients registered in the Canadian Kidney Cancer Information System treated at 16 institutions between 2011 and 2018 were included. Baseline patient, tumour, and treatment characteristic...

Conclusion: 3T3-L1 cells, treated with LPV/RTV, show altered lipid content due to increased miRNA-218 levels, which affects lipin-1 mRNA. Moreover, increased miRNA-218 levels were inversely correlated with changes in GLUT-4 expression, which suggests a role for miRNA-218 in mediating the insulin resistance consequent to cART. Introduction Metabolic syndrome is a serious consequence of combined Antiretroviral Therapy (cART). HIV-associated metabolic syndrome is often accompanied by lipodystrophy (LS), the redistribution of body fat with loss of subcutaneous adipose tissue in face, limbs and buttocks, concomitant wit...

In conclusion, we showed that IGFs and insulin may play a stimulatory role for renal cancer cells, thus they can possibly affect renal cancer tumorigenesis and progression on cellular level. PMID: 30929166 [PubMed - as supplied by publisher]

Conclusions: Average age at the time of diagnosis of RCC in Sri Lankan patients is lower than the developed world, with a large proportion of patients being under 50 years. Obesity, hypertension, and DM are associated risk factors for RCC in Sri Lankan patients while smoking is not.

Abstract Vitamin D activity is controlled by its receptor (VDR) located in many cells of the body. The presence of VDR in numerous cellular pathways suggests its important role in the etiology and development of many diseases. Increased risk of obesity, metabolic disturbances, bone mass disturbances and neoplasia among certain VDR alleles has been proven. The importance of VDR in the etiopathology of obesity is associated with the occurrence of polymorphisms: Fok1, Bsm1, Apa1, Taq1. VDR expression in adipocytes plays a role in the regulation of energy metabolism and the induction of obesity. Vitamin D and VDR poly...

Abstract INTRODUCTION: Identify modifiable factors contributing to renal cell carcinoma in the PCLO to target disease prevention and reduce health care costs. METHODS: The prostate, lung, colorectal, and ovarian database were queried for the primary outcome of kidney cancer. Demographics were investigated, specifically focusing on modifiable risk factors. Statistical analysis includes the Student t-test for continuous variables, chi-squared or Fisher's exact tests for dichotomous and categorical variables for bivariate analysis. The Cox proportional hazards model was used in a multivariate time-to-event analy...

Objectives: To examine whether serum adiponectin or leptin level has the ability to differentiate clear cell renal cell carcinoma (ccRCC) from other subtypes of renal cell carcinoma (RCC) in a Chinese population.Patients and methods: We recruited 198 consecutive patients who were treated with radical or partial nephrectomy in our department from September 2011 to June 2013. Their histological types were all malignant, including clear cell, papillary, chromophobe and unclassified RCC. We also enrolled 86 people with no cancer or cancer-related diseases as normal controls. We measured patients' preoperative blood samples for...

Abstract PURPOSE: The 34-gene classifier, ClearCode34, identifies prognostically distinct molecular subtypes of clear cell renal cell carcinoma (ccRCC) termed clear cell A (ccA) and clear cell B (ccB). The primary objective of this study was to describe clinical characteristics and comorbidities of relevance in patients stratified by ClearCode34. PATIENTS AND METHODS: In this retrospective analysis, 282 patients from Moffitt Cancer Center with ccRCC with gene expression analyses of the primary tumor were identified and ClearCode34 was applied to identify tumors as ccA or ccB. The medical record and institutio...
