Single Amino Acid Replacement in G-7039 Leads to a 70-Fold Increase in Binding Towards GHS-R1a.

The growth hormone secretagogue receptor type 1a (GHS-R1a) is a Class A, rhodopsin-like G Protein Coupled Receptor (GPCR) that is expressed in a variety of human tissues and is differentially expressed in benign and malignant prostate cancer. Previously the peptidomimetic [Lys5(4-fluorobenzoyl-4-FB)]G7039 was designed as a molecular imaging tool for positron emission tomography (PET). However, this […]

Are superior cervical sympathetic ganglia avid on whole body 68Ga-PSMA-11 PET/magnetic resonance?: a comprehensive morphologic and molecular assessment in patients with prostate cancer.

Recent reports warn against erroneous mistaking of celiac and stellate sympathetic ganglia for metastatic lymph nodes on multimodal prostate-specific membrane antigen (PSMA)-ligand PET imaging. The aim was to check the intensity of Ga-PSMA-11 uptake and magnetic resonance (MR) features of superior cervical ganglia (SCG) on PET/MR imaging. In 89 patients 106 SCG were reliably identified […]

Risk stratification and avoiding overtreatment in localized prostate cancer.

Significant morbidity is associated with overtreatment of clinically localized prostate cancer (PCa). Risk stratification tools such as novel biomarkers, MRI and risk calculators are useful in predicting which patients would benefit from active surveillance. This review examines current risk stratification tools in localized PCa and the safety of active surveillance in these patients. Very low […]

Lymph node density for stratification of survival outcomes with node positive upper tract urothelial carcinoma.

The use of lymph node density (LND) as a predictor of survival outcomes has been studied with urothelial carcinoma of the bladder. Similar results can be postulated to upper tract urothelial carcinoma (UTUC). This study aims to determine the overall survival of patients with lymph node positive UTUC based on LND, utilizing the National Cancer […]

Development of a noninvasive tool to preoperatively evaluate the muscular invasiveness of bladder cancer using a radiomics approach.

Bladder cancer (BCa) can be divided into muscle-invasive BCa (MIBC) and non-muscle-invasive BCa (NMIBC). Whether the tumor infiltrates the detrusor muscle is a critical determinant of disease management in patients with BCa. However, the current preoperative diagnostic accuracy of muscular invasiveness is less than satisfactory. The authors report a radiomic-clinical nomogram for the individualized preoperative […]

APCCC 2019: First – line mCRPC after Docetaxel or AR Pathway Inhibitor in the mHSPC Setting

Basel, Switzerland (UroToday.com) The management of castration-resistant prostate cancer (CRPC) session at the Advanced Prostate Cancer Consensus meeting (APCCC) 2019 included a presentation by Mary-Ellen Taplin, MD regarding the first-line treatment of metastatic CRPC (mCRPC) after docetaxel or AR pathway inhibitors in the metastatic hormone-sensitive prostate cancer (mHSPC) setting. Dr. Taplin notes that there is currently […]

APCCC 2019: Prevention and Treatment of Osteoporosis: What More do We Need to Know?

Basel, Switzerland (UroToday.com) Prostate cancer leader Fred Saad, MD spoke at the bone and bone metastases session this afternoon at the Advanced Prostate Cancer Consensus Conference (APCCC) 19 by discussing the prevention and treatment of osteoporosis. According to Dr. Saad, the risks and consequences of osteoporosis are well-established: among all men, there is a 4.6% life-time […]
