Purpose To assess the association of lymphovascular invasion (LVI) with cancer recurrence and survival in a large international series patients treated radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC). Patients Methods Data were collected on 1,453 RNU at 13 academic centers combined into relational database. Pathologic slides rereviewed by genitourinary pathologists according to strict criteria. LVI was defined as presence tumor cells within an...

Abstract Context: Aldosterone synthase (CYP11B2) and steroid 11β-hydroxylase (CYP11B1) catalyze the terminal steps for aldosterone cortisol syntheses, respectively, thereby determining functional differentiation of human adrenocortical cells. Little is known, however, about how cells expressing enzymes are actually distributed in adrenals under normal pathological conditions. Objective: The objective study was to determine localization CYP11B2 -B1 adrenal specimens by using developed...

BACKGROUND: Preclinical studies and results of a phase 2 trial abiraterone olaparib suggest combined antitumor effect when the poly(adenosine diphosphate[ADP]-ribose) polymerase inhibitor is with next-generation hormonal agent to treat metastatic castration-resistant prostate cancer (mCRPC). METHODS: We conducted double-blind, 3 versus placebo in patients mCRPC first-line setting. Patients were enrolled regardless homologous recombination repair gene mutation (HRRm) status. HRRm status was...

11 Background: Preclinical studies have shown combined anti-tumor effect through interactions between poly(adenosine diphosphate–ribose) polymerase and androgen receptor signaling pathways. A Phase II trial (NCT01972217) in pts with mCRPC unselected by homologous recombination repair (HRR) status who previously received docetaxel demonstrated improved radiographic progression-free survival (rPFS) for treated ola + abi vs pbo (Clarke N, 2018). The III PROpel study (NCT03732820) evaluates the...

BackgroundBelzutifan, a hypoxia-inducible factor 2α inhibitor, showed clinical activity in clear-cell renal-cell carcinoma early-phase studies.MethodsIn phase 3, multicenter, open-label, active-controlled trial, we enrolled participants with advanced who had previously received immune checkpoint and antiangiogenic therapies randomly assigned them, 1:1 ratio, to receive 120 mg of belzutifan or 10 everolimus orally once daily until disease progression unacceptable toxic effects occurred. The...

Lateral lymph node metastases occur in some patients with low rectal cancer and may cause local recurrence after total mesorectal excision. The aims of this study were to identify risk factors for lateral pathological tumour (pT) stage 3 or pT4 adenocarcinoma, evaluate the prognostic significance metastases.A retrospective analysis was performed outcome 237 pT3 adenocarcinoma who underwent R0 resection systematic dissection.Lateral found 41 (17.3 per cent). Increased associated a distal...

There is relatively little literature on adjuvant chemotherapy after radical nephroureterectomy in patients with upper tract urothelial carcinoma. We determined the incidence of high risk and ensuing effect overall cancer specific survival.Using an international collaborative database we identified 1,390 who underwent for nonmetastatic carcinoma between 1992 2006. Of these cases 542 (39%) were classified as (pT3N0, pT4N0 and/or lymph node positive). These divided into 2 groups, including...

Abstract Neuroendocrine prostate cancer (NEPC) is an aggressive malignancy with no effective targeted therapies. The oncogenic MUC1-C protein overexpressed in castration-resistant (CRPC) and NEPC, but its specific role unknown. Here, we demonstrate that upregulation of androgen-dependent PC cells suppresses androgen receptor (AR) axis signaling induces the neural BRN2 transcription factor. activates a MYC→BRN2 pathway association induction MYCN, EZH2 NE differentiation markers (ASCL1, AURKA...

Abstract Acquisition of mesenchymal properties by cancer cells is critical for their malignant behaviour, but regulators the molecular machinery and how it activated remain elusive. Here we show that clear cell renal carcinomas (ccRCCs) frequently utilize Arf6-based pathway to promote invasion metastasis, similar breast cancers. In cells, ligand-activated receptor tyrosine kinases employ GEP100 activate Arf6, which then recruits AMAP1; AMAP1 binds mesenchymal-specific protein EPB41L5,...

The polybromo-associated PBAF (SWI/SNF) chromatin remodeling complex, which includes PBRM1, ARID2, and BRD7, regulates cell differentiation genomic integrity. MUC1-C is an oncogenic protein that drives lineage plasticity in prostate cancer (PC) progression. present work demonstrates induces BRD7 expression by the previously unrecognized E2F1-mediated activation of their respective promoters. functional significance MUC1-C→PBAF pathway supported demonstrating involvement associating with...
