Clear cell Renal Cell Carcinoma (ccRCC) causes over 13,000 deaths each year, and about 20,000 new cases/year in Europe. In most cases, the causes are unknown and, most importantly, there are no reliable biomarkers for the diagnosis and prognosis of this disease. The search for sensitive biomarkers for early diagnosis and prognosis of clear cell Renal Cell Carcinoma (ccRCC) is currently a fast growing field. We carried out proteomics analysis of 93 urinary samples of healthy subjects (HS) and patients affected by ccRCC, prostate cancer (PCa) and chronic kidney disease (CKD), that was able to successfully distinguish each group...

Incomplete resections and damage to critical structures increase morbidity and mortality of patients with cancer. Targeted intraoperative fluorescence imaging aids surgeons by providing real-time visualization of tumors and vital structures. This study evaluated the tumor-targeted zwitterionic near-infrared fluorescent peptide cRGD-ZW800-1 as tracer for intraoperative imaging of multiple cancer types. cRGD-ZW800-1 was validated in vitro on glioblastoma (U-87 MG) and colorectal (HT-29) cell lines. Subsequently, the tracer was tested in orthotopic mouse models with HT-29, breast (MCF-7), pancreatic (BxPC-3), and oral (OSC-19) tumors...

Renal function after renal cancer surgery is a critical component of survivorship. Quantity and quality of preserved parenchyma are the most important determinants of functional recovery; type and duration of ischemia play secondary roles. Several studies evaluated surgical techniques to minimize ischemia; however, long-term outcomes and potential benefits over clamped partial nephrectomy (PN) have not been consistently demonstrated. Analysis of acute kidney injury (AKI) after PN suggest that most kidneys recover strongly even if AKI is experienced after surgery...

Immunotherapy targeting the programmed death-1 (PD-1) receptor/PD-1 ligand (PD-L1) pathway has shown promising results in several malignancies. However, the prognostic significance of PD-L1 expression remains unknown in patients with upper tract urothelial carcinoma (UTUC). This study aimed to evaluate PD-L1 expression and its association with clinicopathological characteristics and oncological outcomes in UTUC patients. PD-L1 expression on tumor cells and tumor-infiltrating mononuclear cells (TIMCs), and E-cadherin and N-cadherin expression on tumor cells were assessed by immunohistochemistry in a cohort of 162 patients with UTUC...

The clinical impact and accessibility of (68)Ga tracers for the prostate-specific membrane antigen (PSMA) and other targets would be greatly enhanced by the availability of a simple, one-step kit-based labeling process. Radiopharmacy staff are accustomed to such procedures in the daily preparation of (99m)Tc radiopharmaceuticals. Currently, chelating agents used in (68)Ga radiopharmaceuticals do not meet this ideal. AIM: To develop and evaluate preclinically a (68)Ga radiotracer for imaging PSMA expression that could be radiolabeled simply by addition of (68)Ga generator eluate to a cold kit...

To develop a treatment protocol for (225)Ac-PSMA-617 alpha-radiation therapy in advanced stage, metastatic castration-resistant prostate cancer patients with PSMA-positive tumor phenotype. Methods: A dosimetry estimate was calculated based on time-activity-curves derived from serially performed (177)Lu-PSMA-617 scans extrapolated to the physical half-life of (225)Ac, assuming instant decay of instable daughter nuclides. Salvage therapies empirically conducted with 50kBq/kg (n = 4), 100kBq/kg (n = 4), 150kBq/kg (n = 2), 200kBq/kg (n = 4) (225)Ac-PSMA-617 were evaluated retrospectively regarding toxicity and treatment response...

BACKGROUND: Chronic immunosuppression promotes Nonmelanocytic Squamous Cell Carcinoma (SCC) after kidney transplantation. Adaptive and innate immunity play a key role controlling tumor growth and are influenced by different immunosuppressive agents. We hypothesized that functional impairment of tumor-specific T cell responses due to CNI could contribute to SCC development, whereas conversion to mTOR-i could recover this protective immune response. METHODS: Peripheral tumor-specific T cell responses against main SCC-derived antigens using the IFN-γ ELISPOT assay and intratumor and circulating immune phenotypes (CD4+T, CD8+T, CD20+B, CD56+NK, FOXP3+Tregs) were explored in a cross-sectional analysis in 59 kidney transplant patients with SCC on CNI (KT-CNI-SCC) or mTOR-i (KT-mTORi-SCC), 25 nontransplants developing SCC (NoKT-SCC) and 6 healthy controls...

Adenosine triphosphate (ATP)-binding cassette (ABC) transporters are highly expressed in tumor cells, as well as in organs involved in absorption and secretion processes, mediating the ATP-dependent efflux of compounds, both endogenous substances and xenobiotics, including drugs. Their expression and activity levels are modulated by the presence of inhibitors, inducers and/or activators. In vitro, ex vivo and in vivo studies with both known and newly synthesized P-glycoprotein (P-gp) inducers and/or activators have shown the usefulness of these transport mechanisms in reducing the systemic exposure and specific tissue access of potentially harmful compounds...

Solid organ transplant recipients have an elevated incidence of thyroid cancer. We evaluated a wide range of potential risk factors in a cohort of 229,300 U.S. solid organ transplant recipients linked with 15 stage/regional cancer registries (1987-2012). Incidence rate ratios (IRRs) were adjusted for age, sex, race/ethnicity, transplanted organ, year of transplant, and time since transplant. Hazards ratios (HRs) for death and/or graft failure were adjusted for age, sex, race/ethnicity, transplanted organ, and year of transplant...

PURPOSE: Chronic kidney disease may adversely affect survival following nephrectomy. Proteinuria is increasingly used as a marker for kidney disease. However, the relationship between preoperative proteinuria and survival following nephrectomy remains incompletely characterized. We sought to evaluate the association of preoperative proteinuria with overall and cancer-specific survival using our institutional nephrectomy registry. MATERIALS AND METHODS: We identified 1,846 patients with localized clear cell renal cell carcinoma treated with curative intent (radical or partial nephrectomy) between 1995 and 2010...

We have, in previous work developed, characterized and evaluated the biocompatibility of an engineered hyaluronic acid nanogel. Here we assess the targetability of a hyaluronic acid nanogel towards CD44 overexpressing cells, in vitro and in vivo. Results obtained by flow cytometry and confocal fluorescence microscopy shows that nanogel is greatly internalized by non-small cancer lung cells (A549 cells), that overexpress CD44 receptors. The biodistribution and tumor targetability of the nanogel labelled with a near-infrared (NIR) probe were performed, in mice, through a non-invasive imaging system...

Exercise capacity is one of the most powerful predicting factors of life expectancy, both in patients with and without cardiac disease. Cardiopulmonary exercise testing provides a global assessment of the integrative exercise responses involving the pulmonary, cardiovascular, hematopoietic, neuropsychological, and skeletal muscle systems, which are not adequately reflected through the measurement of individual organ system function. This relatively noninvasive, dynamic, physiologic overview allows the evaluation of both submaximal and peak exercise responses, providing the physician with relevant information for clinical decision making...

Integrin α3β1 has been shown to be a novel candidate target for the imaging and specific therapy of non-small-cell lung cancer. We have previously reported on a peptide containing a novel motif of NGXG that specifically binds to the integrin α3 receptor on lung cancer cells using a one-bead one-peptide combinatorial library. In this study, we developed the peptide cNGEGQQc-based therapeutic agent labeling with radionuclide iodine-131 (I) and evaluated its characteristics including stability, biodistribution, antitumor activity, and safety...

The kidney is one of the most radiosensitive organs in the abdominal cavity and is the dose-limiting structure in cancer patients receiving abdominal or total body irradiation. In the present study, the effect of coenzyme Q10 (CoQ10) on radiation nephropathy was evaluated in rats. A total of 72 rats were equally randomized into 4 groups: Control, CoQ10, irradiation with 10 Gy (RT) + placebo, or RT + CoQ10. The 2 RT groups received single 10 Gy of abdominal irradiation. The 2 CoQ10 groups were supplemented daily with 1 mL of soybean oil containing 10 mg/kg of CoQ10...
