Targeting PDGF-mediated recruitment of pericytes blocks vascular mimicry and tumor growth.

Aggressive tumor cells can adopt an endothelial cell-like phenotype and contribute to the formation of a tumor vasculature, independent of tumor angiogenesis. This adoptive mechanism is referred to as vascular mimicry and it is associated with poor survival in cancer patients. To what extent tumor cells capable of vascular mimicry phenocopy the angiogenic cascade is still poorly explored.

Promoter CpG island methylation in ion transport mechanisms and associated dietary intakes jointly influence the risk of clear-cell renal cell cancer.

Background: Sodium intake, but not potassium or fluid intake, has been associated with higher renal cell cancer (RCC) risk. However, risk factors may differ by molecular subtypes of the tumour. In renal physiology, electrolyte and water homeostasis is facilitated by ion transport mechanisms (ITM).

Effect of Itraconazole and Rifampin on the Pharmacokinetics of Olaparib in Patients With Advanced Solid Tumors: Results of Two Phase I Open-label Studies.

Purpose: The metabolism of olaparib, a potent inhibitor of poly(ADP-ribose) polymerase (PARP) with demonstrated efficacy in patients with BRCA-mutated ovarian cancer, is mediated by cytochrome P450 (CYP) enzymes (predominantly CYP3A4/5). We assessed the potential of a CYP3A4 inhibitor (itraconazole) and inducer (rifampin) to alter the pharmacokinetic (PK) profile of olaparib following single oral tablet doses.

Methods: Two Phase I, open-label, non-randomized trials were conducted in patients with advanced solid tumors.

Adherence to guideline recommendations for management of clinical T1 renal cancers in the Netherlands: a population-based study.

Purpose: For decades, small renal cancers are treated by radical nephrectomy (RN). Current guidelines recommend partial nephrectomy (PN) to preserve renal function and minimize cardiovascular comorbidity. As adherence to guidelines is largely unknown and international comparison to evaluate quality of health care is lacking, an pre-specified guideline evaluation of quality indicators concerning management of cT1 renal cancers was performed.

Olaparib tablet formulation: effect of food on the pharmacokinetics after oral dosing in patients with advanced solid tumours.

Background: The oral PARP inhibitor olaparib has shown efficacy in patients with BRCA-mutated cancer. This Phase I, open-label, three-part study (Parts A-C) in patients with advanced solid tumours evaluated the effect of food on the pharmacokinetics (PK) of olaparib when administered in tablet formulation.

Methods: PK data were obtained in Part A using a two-treatment period crossover design; single-dose olaparib 300 mg (two 150 mg tablets) was administered in two prandial states: fasted and fed.
