Background: Cabozantinib (CBZ) is a receptor tyrosine kinase inhibitor with activity against MET, VEGFR2, FLT3, c-KIT, and RET. Pre-clinical studies in models of prostate cancer bone metastasis demonstrated that CBZ treatment induced both a suppression of tumour growth and an alteration in bone remodelling, suggesting that both tumour and bone microenvironment represented potential CBZ targets. This is the first study exploring the potential direct activity of CBZ in bone usin...

Aims: Using an extensive bioinformatic approach we identified integrin α5 subunit as a novel potential target to treat bone dissemination from breast cancer. Aim of this study is to confirm the value of this target.Methods: Integrin α5 mRNA expression levels were quantified by qRT-PCR, using radically resected primary tumors of 427 breast cancer patients. α5 expression at protein level by IHC on primary tumor was correlated, in an addition...

Introduction: Denosumab, a fully human monoclonal antibody to RANK ligand, effectively reduces bone resorption by inhibiting RANK-L binding to RANK. We aimed to evaluate the efficacy of denosumab in post-menopausal women, by monitoring the evolution of different parameters of bone health: T-score, morphometry, osteocalcin and β-Ctx.Methods: A 34 women with severe postmenopausal osteoporosis, characterized by multiple vertebral fractures wer...

Reduced bone mineral density (BMD) has been reported to adversely affect health related quality of life (HRQoL) also in postmenopausal women without vertebral fracture. To date no data exist in literature about any possible influences of quantitative ultrasonography (QUS) on HRQoL. This study aimed to assess whether QUS parameters at calcaneous may be associated with HRQoL.In 1812 ambulatory postmenopausal women aged 60 years or over, referred by their f...

Objectives: We aimed to analyze bone mineralization in postmenopausal women of Southern Apulia and to evaluate the effect of obesity-related phenotypes as BMI ≥30 kg/m2, diabetes, hypertension and cardiovascular diseases.Methods: The PROF project is a population-based study on 3.356 subjects (40–99 years) analyzed by phalangeal quantitative ultrasound (QUS) to evaluate bone mineral status. A total of 2.756 postmenopausal women were ...

Objectives: Type 2 diabetes mellitus (T2DM) is associated to an higher risk of fractures despite a normal or increased bone mineral density measured by dual-energy X-ray absorptiometry (DXA).The purpose of this 3-years longitudinal study was to assess the changes of quantitative ultrasound (QUS) parameters in a group of postmenopausal women with T2DM and in healthy controls.Materials and method: The analyses were performed on a gro...

The identification of markers indicative of pathological FMS plays a pivotal role in the prevention of ACH complications.Objective: Identify key cranio-cervical junction neuroradiological features for the surgical choice and for the decompression outcome.Methods: Out of 191 ACH patients, we selected 24 patients before 4 years of age, who performed a first brain MRI and/or CT. Patients were divided into 2 groups: surgically treated ...
