ALK-rearranged RCC refractory to several lines of treatment has a durable response when treated with alectinib.

Gain of Chromosome 5q Predicts a Favorable Prognosis in Localized Renal Cell Carcinoma.

Approximately 65% of renal cell carcinomas (RCC) are diagnosed at a localized stage. We investigated the chromosome 5q gain impact on disease-free survival (DFS) in RCC patients. Overall, 676 patients with stages 1-2 RCC and having cytogenetic analysis were included.

Do Cancer Genetics Impact Treatment Decision Making? Immunotherapy and Beyond in the Management of Advanced and Metastatic Urothelial Carcinoma.

Bladder cancer is one of the most commonly diagnosed genitourinary malignancies. For many years, the primary treatment for metastatic urothelial cancer (mUC) was predicated on the use of platinum-based chemotherapy. More recently, immune checkpoint inhibitors (ICIs) were approved by regulatory agencies such as the US FDA for use in both the first- and second-line settings.

MRI-guided focused ultrasound focal therapy for patients with intermediate-risk prostate cancer: a phase 2b, multicentre study.

Background: Men with grade group 2 or 3 prostate cancer are often considered ineligible for active surveillance; some patients with grade group 2 prostate cancer who are managed with active surveillance will have early disease progression requiring radical therapy. This study aimed to investigate whether MRI-guided focused ultrasound focal therapy can safely reduce treatment burden for patients with localised grade group 2 or 3 intermediate-risk prostate cancer.

Methods: In this single-arm, multicentre, phase 2b study conducted at eight health-care centres in the USA, we recruited men aged 50 years and older with unilateral, MRI-visible, primary, intermediate-risk, previously untreated prostate adenocarcinoma (prostate-specific antigen ≤20 ng/mL, grade group 2 or 3; tumour classification ≤T2) confirmed on combined biopsy (combining MRI-targeted and systematic biopsies).

Pathological and genetic markers improve recurrence prognostication with the University of California Los Angeles Integrated Staging System for patients with clear cell renal cell carcinoma.

Purpose: To elucidate which patients with clear cell renal cell carcinoma have the highest risk for disease relapse after curative nephrectomy is challenging but is acutely relevant in the era of approved adjuvant therapies. Pathological and genetic markers were used to improve the University of California Los Angeles Integrated Staging System (UISS) for the risk stratification and prognostication of recurrence free survival (RFS).

Patients And Methods: Necrosis, sarcomatoid features, Rhabdoid features, chromosomal loss 9p, combined chromosomal loss 3p14q and microvascular invasion (MVI) were tested in univariable and multivariable analyses for their ability to improve the discriminatory ability of the UISS.

A Phase I, Open-Label, Dose-Finding Study of GSK2636771, a PI3Kβ Inhibitor, Administered with Enzalutamide in Patients with Metastatic Castration-Resistant Prostate Cancer.

Purpose: In patients with metastatic castration-resistant prostate cancer (mCRPC), resistance to androgen receptor (AR)-targeted therapies, such as enzalutamide, remains an issue. Inactivation of inhibitory PTEN activates PI3K/AKT signaling and contributes to resistance to androgen deprivation therapy and poor outcomes. Therefore, dual targeting of AR and PI3K/AKT pathways may limit tumor growth and reverse resistance.

Exploratory analysis of the platelet-to-lymphocyte ratio prognostic value in the adjuvant renal cell cancer setting.

To examine the prognostic value of the platelet-to-lymphocyte ratio (PLR) in the adjuvant renal cell carcinoma setting. Patients received adjuvant sunitinib (50 mg/day; 4 weeks on/2 weeks off) or placebo. The primary end point was disease-free survival (DFS).

Magnetic Resonance Imaging-Guided Transurethral Ultrasound Ablation of Prostate Cancer.

Purpose: Magnetic resonance imaging-guided transurethral ultrasound ablation uses directional thermal ultrasound under magnetic resonance imaging thermometry feedback control for prostatic ablation. We report 12-month outcomes from a prospective multicenter trial (TACT).

Materials And Methods: A total of 115 men with favorable to intermediate risk prostate cancer across 13 centers were treated with whole gland ablation sparing the urethra and apical sphincter.

A Phase I, Open-label, Dose-escalation, and Cohort Expansion Study to Evaluate the Safety and Immune Response to Autologous Dendritic Cells Transduced With AdGMCA9 (DC-AdGMCAIX) in Patients With Metastatic Renal Cell Carcinoma.

Expression of carbonic-anhydrase IX (CAIX) in clear cell renal cell carcinoma (RCC) makes it an attractive vaccine target. We developed a fusion-gene construct, granulocyte-macrophage (GM) colony-stimulating factor+CAIX, delivered by an adenoviral vector (Ad) into autologous dendritic cells (DCs) in this phase 1 study. The injected immature DCs were expected to stimulate an antigen-specific immune response against CAIX expressing RCC.

Neutrophil-to-Lymphocyte Ratio as a Prognostic Factor of Disease-free Survival in Postnephrectomy High-risk Locoregional Renal Cell Carcinoma: Analysis of the S-TRAC Trial.

Purpose: In the S-TRAC trial, adjuvant sunitinib improved disease-free survival (DFS) compared with placebo in patients with locoregional renal cell carcinoma (RCC) at high risk of recurrence. This exploratory analysis investigated the neutrophil-to-lymphocyte ratio (NLR) for predictive and prognostic significance in the RCC adjuvant setting.

Experimental Design: Kaplan-Meier estimates and Cox proportional analyses were performed on baseline NLR and change from baseline at week 4 to assess their association with DFS.

The society for immunotherapy of cancer consensus statement on immunotherapy for the treatment of advanced renal cell carcinoma (RCC).

The approval of immunotherapeutic agents and immunotherapy-based combination strategies in recent years has revolutionized the treatment of patients with advanced renal cell carcinoma (aRCC). Nivolumab, a programmed death 1 (PD-1) immune checkpoint inhibitor monoclonal antibody, was approved as monotherapy in 2015 for aRCC after treatment with a VEGF-targeting agent. In April 2018, the combination of nivolumab and ipilimumab, a CTLA-4 inhibitor, was approved for intermediate- and poor-risk, previously untreated patients with aRCC.

Association of tumor grade, enhancement on multiphasic CT and microvessel density in patients with clear cell renal cell carcinoma.

Purpose: Clear cell renal cell carcinoma (ccRCC) comprises nearly 90% of all diagnosed RCC subtypes and has the worst prognosis and highest metastatic potential. The strongest prognostic factors for patients with ccRCC include histological subtype and Fuhrman grade, which are incorporated into prognostic models. Since ccRCC is a highly vascularized tumor, there may be differences in enhancement patterns on multidetector CT (MDCT) due to the hemodynamics and microvessel density (MVD) of the lesions.

The VENUSS prognostic model to predict disease recurrence following surgery for non-metastatic papillary renal cell carcinoma: development and evaluation using the ASSURE prospective clinical trial cohort.

Background: The current World Health Organization classification recognises 12 major subtypes of renal cell carcinoma (RCC). Although these subtypes differ on molecular and clinical levels, they are generally managed as the same disease, simply because they occur in the same organ. Specifically, there is a paucity of tools to risk-stratify patients with papillary RCC (PRCC).

Positive surgical margins at radical prostatectomy in the United States: Institutional variations and predictive factors.

Introduction: Positive surgical margins (PSMs) are associated with treatment failure after radical prostatectomy (RP) for patients with prostate cancer (CaP). We investigated institutional variations in PSM after RP, as well as clinical and demographic factors predicting PSM.

Patients And Methods: Patients undergoing RP for clinically localized CaP were identified in the National Cancer Database in 2010 to 2013 and clinicodemographics were recorded.

Evaluation of the prognostic role of co-morbidities on disease outcome in renal cell carcinoma patients.

Background: Co-morbidities may induce local and systemic tumor progression of renal cell carcinoma (RCC); however, the prognostic impact of co-morbidities has not yet been well characterized.

Patients And Methods: RCC patients (n = 2206) surgically treated at three academic institutions in the US and Europe were included in the analysis. Presence of diabetes mellitus, hypertension, chronic kidney disease, chronic obstructive pulmonary disease, coronary heart disease, and hypothyroidism were investigated for their association with clinicopathological features and cancer-specific survival.

Cytoreductive nephrectomy in patients with metastatic renal cell carcinoma and venous thrombus-Trends and effect on overall survival.

Purpose: Patients with metastatic renal cell carcinoma (mRCC) commonly present with tumor thrombi in the renal vein and inferior vena cava (IVC). The benefit of cytoreductive nephrectomy (CN) in this population is unclear and the effect on overall survival (OS) has been incompletely evaluated.

Materials And Methods: We queried the National Cancer Database from 2010 to 2013 for patients diagnosed with mRCC and tumor thrombi, which was defined as renal vein, infradiaphragmatic IVC, or supradiaphragmatic IVC.

Melanoma-associated antigen-A and programmed death-ligand 1 expression are associated with advanced urothelial carcinoma.

Background: Melanoma-associated antigen-A (MAGE-A) and programmed-death ligand 1 (PD-L1) are present in urothelial carcinoma (UC). We assessed survival outcomes in patients with MAGE-A and PD-L1 expression.

Methods: MAGE-A and PD-L1 expression on neoplastic cells was analyzed using tissue microarrays from patients with UC.

Variation in surgical treatment patterns for patients with prostate cancer in the United States: Do patients in academic hospitals fare better?

Introduction: With prostate cancer (CaP) screening, overtreatment of low-risk CaP remains a concern. We investigated the patterns of radical prostatectomy (RP) for pathologic insignificant (iCaP) and significant CaP (sCaP) as well as variations between academic and nonacademic hospitals.

Patients And Methods: Patients undergoing RP for clinical T1c CaP were identified in the National Cancer Database between 2006 and 2013.

Phase III Trial of Adjuvant Sunitinib in Patients with High-Risk Renal Cell Carcinoma: Exploratory Pharmacogenomic Analysis.

Purpose: In the S-TRAC trial, adjuvant sunitinib prolonged disease-free survival (DFS) versus placebo in patients with loco-regional renal cell carcinoma at high risk of recurrence after nephrectomy. An exploratory analysis evaluated associations between SNPs in several angiogenesis- or hypoxia-related genes and clinical outcomes in S-TRAC.

Patients And Methods: Blood samples were genotyped for 10 SNPs and one insertion/deletion mutation using TaqMan assays.

Association of the Gross Appearance of Intratumoral Vascularity at MDCT With the Carbonic Anhydrase IX Score in Clear Cell Renal Cell Carcinoma.

Objective: The purpose of this study was to determine whether qualitative MDCT features are associated with the carbonic anhydrase IX (CAIX) score of clear cell renal cell carcinoma (RCC). The CAIX score has been previously found to have prognostic significance for disease-free survival, overall survival, and lymph node involvement.

Materials And Methods: A cohort of 105 histologically proven clear cell RCCs in patients who underwent preoperative four-phase renal mass MDCT was derived from 2001 to 2013.

Treatment utilization and overall survival in patients receiving radical nephroureterectomy versus endoscopic management for upper tract urothelial carcinoma: evaluation of updated treatment guidelines.

Purpose: While radical nephroureterectomy (RNU) is the gold standard treatment for upper tract urothelial carcinoma (UTUC), select patients may benefit from endoscopic treatment (ET). European Association of Urology guidelines recommend ET for patients with low-risk (LR) disease: unifocal, < 2 cm, low-grade lesions without local invasion. To inform the utility of ET, we compare the overall survival (OS) of patients receiving ET and RNU using current and previous guidelines of LR disease.
