BACKGROUND Androgen receptor (AR) signalling remains critically important in metastatic castration-resistant prostate cancer (mCRPC) as confirmed by recent phase III trials, showing a survival advantage for abiraterone acetate and enzalutamide (MDV3100). The antitumour activity of abiraterone and prednisolone in patients pre-treated with enzalutamide is as(More)
PURPOSE Osteonecrosis of the jaws (ONJ) was initially described in 2001 in patients receiving intravenous bisphosphonate (BP) treatment. The objective of the present study was to determine whether routine dental procedures can be considered as possible risk factors for the development of ONJ in breast cancer patients receiving BP. PATIENTS AND METHODS(More)
Bortezomib represents the first proteasome inhibitor (PI) with demonstrated antitumor activity in the clinical setting, particularly for treatment of hematological malignancies. At the preclinical level, its action is shown to be mediated by induction of growth arrest and apoptosis in many tumor types, including androgen-dependent (AD) and(More)
Castration-resistance in prostate cancer (PC) is a critical event hallmarking a switch to a more aggressive phenotype. Neuroendocrine differentiation and upregulation of NFκB transcriptional activity are two mechanisms that have been independently linked to this process. We investigated these two pathways together using in vitro models of androgen-dependent(More)
Upregulation of nuclear factor kappa B (NFκB) activity and neuroendocrine differentiation are two mechanisms known to be involved in prostate cancer (PC) progression to castration resistance. We have observed that major components of these pathways, including NFκB, proteasome, neutral endopeptidase (NEP) and endothelin 1 (ET-1), exhibit an inverse and(More)
BACKGROUND Head and neck cutaneous squamous cell carcinoma (HNCSCC) although rarely fatal has significant adverse public health effects due to high medical costs, compromised quality of life, functional impairment and other serious consequences. The present longitudinal cohort study of HNCSCC was designed to determine whether certain clinical-pathologic(More)
Kaposi's sarcoma is classified into 4 types: classic (sporadic), African (endemic), iatrogenic (transplant recipients), and epidemic (acquired immunodeficiency syndrome [AIDS]-associated). This article aims to feature a comprehensive review of non-AIDS Kaposi's sarcoma, including literature review and report of 3 cases. Case material was from our hospital's(More)
Benign fibrous histiocytoma is an interesting and challenging entity even in its most usual, cutaneous presentation. Noncutaneous presentation is extremely limited, even more so for the mucosa of the head and neck area. We herein report such a case, describing the clinical characteristics of the lesion, complete diagnostic evaluation, management, and(More)
Surgery remains the cornerstone of treatment and the only curative loco-regional approach of localized resectable soft tissue sarcoma (STS) in 2011: the usual first-line treatment is wide margin surgery plus radiotherapy, especially in the case of primary tumors arising in the limbs. An optimal initial R0 resection is one of the most reproducible and(More)
OBJECTIVES Neuropeptides are important signal initiators in advanced prostate cancer, partially acting through activation of nuclear factor kappa B. Central to nuclear factor kappa B regulation is the ubiquitin-proteasome system, pharmacological inhibition of which has been proposed as an anticancer strategy. We investigated the putative role of the(More)
