Abstract Background: While the treatment of metastatic renal cell carcinoma (mRCC) is evolving due to immune checkpoint inhibitors (ICIs), optimal strategies for later lines of therapy have yet to be defined. The combination of lenvatinib and everolimus represents a viable option, and the present review aimed to summarize its activity, effectiveness, and safety. Methods: A systematic review of the literature was conducted using PubMed, targeting studies published between 2018 and 2025. Eligible studies included English-language prospective and retrospective trials reporting survival outcomes in mRCC patients treated with lenvatinib and everolimus after at least one ICI-containing regimen. Results:… More > Graphic Abstract

Abstract Background: Radiogenomics offers a non-invasive approach to correlate imaging features with tumor molecular profiles. This study aims to identify computed tomography (CT) imaging characteristics associated with positive NIPA-like domain containing 4 (NIPAL4) expression in clear cell renal cell carcinoma (ccRCC) and to develop a radiogenomic predictive model to support personalized risk stratification. Methods: A retrospective analysis was conducted on 241 ccRCC patients from The Cancer Genome Atlas (TCGA) and The Cancer Imaging Archive (TCIA) databases. Clinical, pathological, and CT features were compared between NIPAL4-positive and NIPAL4-negative groups. A penalized logistic regression model was built to… More >

Abstract Background: Epithelioid angiomyolipoma (EAML) is an uncommon renal tumor variant with histologic and radiologic features that can mimic renal cell carcinoma (RCC) on imaging due to the paucity of fat compared to the classic AML. EAML may exhibit aggressive behavior, including local invasion, recurrence, and distant metastases to the liver, lungs, and lymph nodes. Although recent reports suggest that up to one-third of EAML cases may behave malignantly, variability in diagnostic criteria and limited case series contribute to uncertainty regarding its true clinical course. Case Description: This case report describes a 19-year-old female presenting with an… More >

Abstract Background: Clear cell renal cell carcinoma (ccRCC) is an aggressive malignancy associated with limited treatment options and poor prognosis. Emerging studies suggest that the actin-regulating protein actin-related protein 2/3 complex subunit 1B (ARPC1B), a key regulatory protein within the actin cytoskeleton, could play a pivotal role in ccRCC progression. The current study aimed to uncover the biological functions of ARPC1B and the molecular mechanisms driving its effects in ccRCC. Methods: ARPC1B expression and prognostic implications were analyzed using data sourced from the Gene Expression Profiling Interactive Analysis (GEPIA) platform, immunohistochemical (IHC) staining on 150 tumor… More >

Abstract Background: Renal cell carcinoma (RCC) is a prevalent malignancy characterized by a rising incidence and significant mortality. Interleukins (ILs) are crucial in regulating immune cell trafficking and exhibit anti-tumor properties. However, limited research has explored the expression levels and prognostic significance of interleukins in RCC. Methods: In this comprehensive study, we performed a detailed analysis of interleukins in RCC patients using multiple bioinformatics tools, including Oncomine, UALCAN, GEPIA, Kaplan-Meier plotter, cBioPortal, GeneMANIA, TRRUST, STRING, and Linked Omics. Results: Our analysis demonstrated a significant upregulation in the transcriptional levels of IL4, IL7, IL15, IL16, IL23A, IL26, and… More >

Abstract Renal cell carcinoma is a heterogeneous group of renal tumors characterized by several histological subtypes. Herein, we discuss an unusual case of a 55-year-old male who presented as a consultation to our urology clinic with an incidentally found renal mass. After shared decision making patient proceeded with a Robotic Assisted Laparoscopy (RAL) left sided partial nephrectomy. Final pathology confirmed the presence of high nuclear grade mixed clear cell and papillary renal cell carcinoma (RCC) of the left kidney (pT3aN0M0). This case elucidates a very rare incidence of a patient seen to have a collision tumor, More >

Abstract Introduction: In recent years, significant advancements in the treatment of metastatic renal cell carcinoma (mRCC) have notably extended overall survival (OS) times, particularly with the introduction of tyrosine kinase inhibitors (TKIs) and combination immunotherapy. However, survival outcomes in mRCC remain highly variable. Materials and Methods: This study retrospectively analyzed clinical and demographic factors at diagnosis in patients treated for mRCC to identify predictors of long-term survival (defined as OS ≥ 48 months). Patients were categorized into long-term survivors (LTS) and non-long-term survivors (nLTS). Results: The analysis revealed that factors such as better Karnofsky Performance Status (KPS), More >

Abstract Background: Clear cell renal carcinoma (ccRCC), the leading histological subtype of RCC, lacks any targeted therapy options. Although some studies have shown that early growth response factor 1 (EGR1) has a significant role in cancer development and progression, its role and underlying mechanisms in ccRCC remain poorly understood. Methods: The Cancer Genome Atlas (TCGA) database was utilized to examine the expression of EGR1 in ccRCC. The expression of EGR1 in 55 ccRCC tissues was evaluated using immunohistochemistry. The link between EGR1 expression and clinicopathological variables was examined through an analysis. Gain-of-function assays were employed to… More >

Abstract Background: Sunitinib resistance is a major challenge in advanced renal cell carcinoma (RCC). Clinically, elucidating the underlying mechanisms and developing practical countermeasures for sunitinib resistance in RCC is desirable. In previous studies, we found that circAGAP1 expression was significantly upregulated in clear cell RCC (ccRCC) and was strongly associated with poor prognosis. However, the role of circAGAP1 in sunitinib resistance in ccRCC remains unclear. Methods: We used public databases for bioinformatics analysis to identify the binding targets of circAGAP1. Additionally, the effects of circAGAP1 on the proliferation, clonogenesis, apoptosis, and migration of ccRCC cells were… More > Graphic Abstract
