Bladder cancer is the sixth most common cancer in the United States, and it exhibits an alarming 70% recurrence rate. Thus, the development of more efficient antibladder cancer approaches is a high priority.

Overexpression of the epidermal growth factor receptor (EGFR) and its ligands occur frequently in renal cell carcinoma (RCC). Combined vascular endothelial growth factor receptor (VEGF-R) and EGFR inhibition may overcome resistance to VEGF-R inhibitor monotherapy.

Dose-escalation of epertinib (S-222611), a new potent oral EGFR/HER2 inhibitor, has established a recommended daily dose of 800 mg in patients with solid tumours. In this study, we have recruited a larger number of patients to assess further the safety, tolerability, pharmacokinetics (PKs) and antitumour activity.

Penile squamous cell carcinoma (SCC) is a rare malignancy with limited treatment options when the tumor is unresectable and/or chemorefractory. Triplet systemic chemotherapy regimens including taxane and cisplatin are recommended, but the response duration can be short and the treatment-related toxicity high.

Assessing the molecular profiles of bladder cancer (BC) from patients with locally advanced or metastatic disease provides valuable insights, such as identification of invasive markers, to guide personalized treatment.

The aim of this review is to evaluate the trends in multidisciplinary management of localized penile cancer and systemic therapy for advanced disease in the evolving era of targeted and immune checkpoint therapy.

3D tissue cultures provide a more physiologically relevant context for the screening of compounds, compared with 2D cell cultures. Cells cultured in 3D hydrogels also show complex phenotypes, increasing the scope for phenotypic profiling.

Mutations and fusions in Fibroblast Growth Factor Receptor 3 (FGFR3) occur in 10-20% of metastatic urothelial carcinomas and confer sensitivity to FGFR inhibitors. However, responses to these agents are often short-lived due to the development of acquired resistance.

We retrospectively analysed the efficacy and safety of sorafenib in patients with advanced renal cell carcinoma with renal impairment.

Patients were divided into two groups by an estimated glomerular filtration rate (eGFR) cut-off of 45 mL/min/1.

Epidermal growth factor receptor (EGFR) is associated with progression of many epithelial malignancies and represents a significant therapeutic target. Although clear cell renal cell carcinoma (CCRCC) has been widely investigated for EGFR molecular alterations, genetic evidences of EGFR gene activating mutations and/or gene amplification have been rarely confirmed in the literature.

Immuno-positron emission tomography (immunoPET) combines the specificity of an antibody with the sensitivity of PET to image dysregulated pathways in cancer. This study examines the performance of immunoPET using the radioimmunoconjugate [89Zr]Zr-DFO-Panitumumab to detect epidermal growth factor receptor (EGFR) expression in an orthotopic model of bladder cancer (BCa).

Penile squamous cell carcinoma (PSCC) is a rare cancer, but is more common in developing countries. Locally advanced and metastatic PSCC is associated with significant morbidity and mortality, with the prognosis remaining extremely poor.

Epidermal growth factor receptor (EGFR) overexpression is believed to be associated with bladder cancer (BC) progression and poor clinical outcomes. In vivo studies have linked EGFR subcellular trafficking and chemo-resistance to cisplatin-based chemotherapies.

Penile carcinoma (PC) is more frequent in underdeveloped countries, generally is diagnosed at an advanced stage when therapeutic options are restricted, and thus is associated with high morbidity/mortality rates.

Muscle-invasive bladder cancer (MIBC) consists of a heterogeneous group of tumors with a high rate of metastasis and mortality. To facilitate the in-depth investigation and validation of tailored strategies for MIBC treatment, we have developed an integrated approach using advanced high-throughput drug screening and a clinically relevant patient-derived preclinical platform.

Knockout of ERβ in the mouse leads to nuclear expression of epidermal growth factor receptor (EGFR) in the prostate. To examine whether ERβ plays a similar role in the human prostate, we used four cohorts of men: 1) a Swedish cohort of normal prostates and PCa (prostate cancer) of different Gleason grades; 2) men with benign prostatic hyperplasia (BPH) treated with the 5α-reductase inhibitor, finasteride, and finasteride together with the ERβ agonists, soy isoflavones; 3) men with PCa above Gleason grade 4 (GG4), treated with ADT (androgen deprivation therapy) and abiraterone (AA), the blocker of androgen synthesis for different durations; and 4) men with GG4 PCa on ADT or ADT with the AR (androgen receptor) blocker, enzalutamide, for 4 mo to 6 mo.

In patients with muscle invasive bladder cancer or high risk noninvasive bladder cancer, renal function decline is a concern after radical cystectomy with urinary diversion. The pathophysiology of this decline is multifactorial, with subclinical acidosis and metabolic derangements from the diversion thought to contribute.

Prostate cancer is one of the leading causes of death in men worldwide. Differentially expressed microRNAs (miRNAs) are associated with metastatic prostate cancer. However, their potential roles for affecting prostate cancer initiation and progression remain largely unknown.

Upper urinary tract urothelial carcinoma (UTUC) is a rare disease, often discovered at an advanced stage at diagnosis. Nectin-4 is expressed in a broad range of patients with UTUC and is associated with poor progression-free survival.

The aim of the study is to clarify the clinical effects of first-line chemotherapy regimens for advanced urothelial cancer on clinical responses and survival of patients grouped by renal function.

In this multicenter retrospective cohort study, 345 urothelial cancer patients received systemic chemotherapy for metastatic or unresectable disease in 17 centers (2004-10).

Penile squamous cell carcinoma is a rare condition that is associated with significant morbidity and mortality in its advanced stages. In today's rapidly evolving field of oncology, physicians and scientists are learning to harness the power of genomics to drive innovative targeted, immunotherapeutic, and multimodal strategies across different cancer types; however, there remains a pressing need for a deeper understanding of the molecular pathways of penile carcinogenesis in order to help direct individualized therapy for patients with this disease.

Long noncoding RNAs (lncRNAs) have emerged as important regulators of cancer progression. Abnormal sialylation leads to renal cell cancer (RCC) malignancy. However, the mechanism of lncRNA maternally expressed gene 3 (MEG3) mediates RCC progression by regulating ST3Gal1 transcription and EGFR sialylation is still unrevealed.

Prostate cancer is the most prevalent malignancy in men, and the identification of novel oncogenes is clinically valuable for early screening, prevention and treatment. Recently, the studies have revealed that long non-coding RNAs (lncRNAs) play important roles in the development and progression of cancers including prostate cancer.

Clear cell renal cell carcinoma (ccRCC), derived from renal tubular epithelial cells, is the most common malignant tumor of the kidney. The study of key genes related to the pathogenesis of ccRCC has become important for gene target therapy.

Dysregulation of miR-514a-3p has been reported in multiple human malignancies. However, its biological function and molecular mechanisms in renal cell cancer (RCC) remain unclear. The aims of this study were to explore the role of miR-514a-3p and its potential mechanism in human RCC.

Mycobacterium bovis bacillus Calmette-Guerin (BCG) remains at the forefront of immunotherapy for treating bladder cancer patients. However, the incidence of recurrence and progression to invasive cancer is commonly observed.

Epidermal growth factor receptor (EGFR) plays a central role in the progression of several human malignancies. Although EGFR is a membrane receptor, it undergoes nuclear translocation, where it has a distinct signalling pathway.

The aim of our study was to show our short-term experience in managing large renal masses (cT1b/T2) through partial nephrectomy (PN) over the last 3 years. Retrospective data collection for all patients managed by PN for renal masses larger than 4 cm over the last 3 years.

The CXCL12/CXCR4 axis transactivates HER2 and promotes intraosseous tumor growth. To further explore the transactivation of HER2 by CXCL12, we investigated the role of small GTP protein Gαi2 in Src and HER2 phosphorylation in lipid raft membrane microdomains and the significance of CXCR4 in prostate cancer bone tumor growth.

Muscle invasive bladder cancer (MIBC) remains a prevalent cancer with limited therapeutic options, obviating the need for innovative therapies. The epidermal growth factor receptor (EGFR) is a linchpin in tumor progression and presents a potential therapeutic target in MIBC.

Epidermal growth factor receptor (EGFR) has been shown to have abnormal expression in many human cancers and is considered as a marker of poor prognosis. Frequency of over expression in bladder cancer has not been studied in our population; therefore we aimed to evaluate the frequency and prognostic significance of EGFR immunohistochemical expression in locoregional population.

We studied epidermal growth factor receptor (EGFR) expression profile in Urothelial Bladder carcinoma (UBC) which is a complex and heterogeneous disease with a large spectrum of histological aspects and deadly potential.

To present the latest evidence related to the impact of ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) on the renal function.

Our review suggests that the overall renal function is not detrimentally affected by endourological interventions (URS, PCNL).

O-linked N-acetylglucosamine (O-GlcNAc or O-GlcNAcylation) is a post-translational modification, which plays a vital role in the progression of various cancers. The purpose of the present study was to assess O-GlcNAcylation in human renal cell carcinoma (RCC).

Systemic therapy for urothelial carcinoma (UC) of the bladder has largely revolved around cytotoxic chemotherapy regimens. However, several recent clinical trials have explored the roles of targeted therapies which specifically inhibit signal transduction pathways.

Previous studies have linked kidney stone disease (KSD) with depression, but there are no reports on the relationship between anxiety and KSD, and the mechanism underlying the potential relationship remains unclear.

Discovery of effective systemic therapies for patients with advanced penile cancer has been slow to occur. Comprehensive genomic profiling from several studies shed light on the molecular oncogenesis of penile squamous cell carcinoma (PSCC) and differences between HPV-related and unrelated tumors.
