RESUMO

INTRODUCTION: Renal cancer ranks 10th in the mortality structure of the Russian Federation. The introduction of checkpoint inhibitors has changed the paradigm of treatment of patients with malignant neoplasms. METHOD: Data from clinical trials have shown good progression-free median and median overall survival. Each cancer center has been accumulating its own experience in treating patients with renal cell cancer by applying modern target drugs and immunotherapy. RESULT: In routine clinical practice, oncologists do not get the results that have been demonstrated in clinical trials when evaluating the effectiveness of the therapy. CONCLUSION: In this single-center clinical study, we discuss the results of using nivolumab as mono-therapy and the combination of nivolumab with ipilimumab in metastatic renal parenchyma cancer patients.

RESUMO

BACKGROUND: Renal cell carcinoma represents 3% of all adult malignancies. MicroRNAs exhibit specific functions in various biological processes through their interaction with cellular mRNA involved in apoptosis and cell cycle control. Recent studies have reported the potential association of single-nucleotide polymorphisms (SNPs) in miRNA-binding sites of VHL-HIF1α pathway genes with renal cancer development and progression. OBJECTIVE: The objective of this study is to investigate SNPs invoking an alteration in the nature of interaction with miRNA binding sites of VHL-HIF1α pathway genes. PATIENTS & METHODS: Total 450 cases of histologically and clinically verified ccRCC and 490 controls were included in our study. Genotyping was performed using a TaqMan PCR allelic discrimination method. Kaplan-Meier method of statistical analysis was implemented to analyze the overall patient survival rate. RESULTS: Polymorphism rs10491534 in TSC1 gene was significantly associated with risk of developing advanced ccRCC. Allele G of rs1642742 in VHL gene was significantly prevalent in ccRCC compared with control group aged 55 and older (OR = 1.5566; CI [1.1532-2.1019]). Results from the dominant model combining individuals with AG or AA genotype showed that the A allele bearers of CDCP1 rs6773576 exhibited higher risk of death compared to GG carriers (HR 3.93, 95% CI 1.76-17.21, log-rank P = 0.0033). CONCLUSION: The present study delineated the association of miRNA binding site variants in VHL-HIF1α pathway genes with the ccRCC risk, which may affect clinical outcome.
