INTRODUCTION: Approximately 50% of men diagnosed with prostate cancer will be exposed to androgen deprivation therapy (ADT) at some stage. The role of ADT in the management of metastatic disease has long been recognised, and its place in the management of localised and locally advanced disease has become clearer in the past few years. Nevertheless, concerns remain that some men might not benefit from ADT in earlier-stage disease. The purpose of the current article is to provide a brief narrative review of the role of ADT as part of a strategy of treatment with curative intent, concentrating mainly on key recent developments in the area...

PURPOSE OF REVIEW: Prostate cancer presents with a multitude of faces. It ranges from localized cancers staying quiescent for many years during active surveillance to the raging diffuse liver metastases causing terminal disease. The incidence of metastatic disease is increasing. This review will highlight some of the recent developments as well as ongoing challenges of managing advanced prostate cancer. RECENT FINDINGS: Significant strides are being made in managing metastatic prostate cancer...

Prostate cancer is the most common cancer in men and the metastatic form of the disease is incurable. We show here that the drebrin/EB3 pathway, which co-ordinates dynamic microtubule/actin filament interactions underlying cell shape changes in response to guidance cues, plays a role in prostate cancer cell invasion. Drebrin expression is restricted to basal epithelial cells in benign human prostate but is upregulated in luminal epithelial cells in foci of prostatic malignancy. Drebrin is also upregulated in human prostate cancer cell lines and co-localizes with actin filaments and dynamic microtubules in filopodia of pseudopods of invading cells under a chemotactic gradient of the chemokine CXCL12...

Purpose Systemic Therapy for Advanced or Metastatic Prostate Cancer: Evaluation of Drug Efficacy is a randomized controlled trial using a multiarm, multistage, platform design. It recruits men with high-risk, locally advanced or metastatic prostate cancer who were initiating long-term hormone therapy. We report survival data for two celecoxib (Cel)-containing comparisons, which stopped accrual early at interim analysis on the basis of failure-free survival. Patients and Methods Standard of care (SOC) was hormone therapy continuously (metastatic) or for ≥ 2 years (nonmetastatic); prostate (± pelvic node) radiotherapy was encouraged for men without metastases...

BACKGROUND: Approximately 20% of men with a diagnosis of prostate cancer present with locally advanced or advanced disease. Few studies consider longer-term impact of disease progression and treatment adverse effects on health-related quality of life (QoL) of these men. OBJECTIVE: Describe changes in health-related QoL over 5 years for men with newly diagnosed locally advanced or advanced prostate cancer. INTERVENTIONS/METHODS: Eighty-one men with locally advanced or advanced prostate cancer referred to the study by their treating urologist completed a self-administered questionnaire assessing distress, cancer-specific distress, decision regret, satisfaction with life, and global and disease-specific health-related QoL...

Purpose: Studies comparing radical prostatectomy (RP) outcomes with those of radiotherapy with or without androgen deprivation therapy (RT±ADT) for prostate cancer (PCa) have yielded conflicting results. Therefore, we used propensity score-matched analysis and competing risk regression analysis to compare cancer-specific mortality (CSM) and other-cause mortality (OCM) between these two treatments. Materials and Methods: The multi-center, Severance Urological Oncology Group registry was utilized to identify 3,028 patients with clinically localized or locally advanced PCa treated by RP (n=2,521) or RT±ADT (n=507) between 2000 and 2016...

Androgen receptor (AR) signaling remains the major oncogenic pathway in prostate cancer (PCa). Androgen-deprivation therapy (ADT) is the principle treatment for locally advanced and metastatic disease. However, a significant number of patients acquire treatment resistance leading to castration resistant prostate cancer (CRPC). Epigenetics, the study of heritable and reversible changes in gene expression without alterations in DNA sequences, is a crucial regulatory step in AR signaling. We and others, recently described the technological advance Chem-seq, a method to identify the interaction between a drug and the genome...

OBJECTIVE: The aim of this study was to assess the health-related quality of life of patients with prostate cancer in advanced phases to obtain additional information on the patients' health. The growing interest in understanding the patient's perspective and the scarcity of prospective studies of this population motivated this research study. MATERIAL AND METHODS: We present an observational study performed on 131 urology consultations, with a sample of 601 patients with locally advanced or metastatic prostate cancer, assessed during 2 visits: baseline and at 12 months...

Nanosomal docetaxel lipid suspension (NDLS) [DoceAqualip] is a novel formulation of docetaxel approved in India for the treatment of breast cancer, hormone-refractory prostate cancer, locally advanced squamous cell carcinoma of the head and neck, non-small cell lung cancer and advanced gastric adenocarcinoma. The lipid-based delivery system of NDLS eliminates the need for polysorbate 80 and ethanol, which are contained in the conventional docetaxel formulation and are associated with hypersensitivity reactions and infusion-related toxicities...

Paracrine and long-range signaling via extracellular vesicles, such as exosomes and microvesicles, is deemed crucial for tumorigenesis, invasion and spread of solid tumors. The ESCRT machinery (endosomal sorting complexes required for transport) and Rab-proteins act as key players in vesicular trafficking and secretion. Yet, their role in prostate cancer (PCa) is unknown. Therefore, this study aimed to elucidate the relevance of these components in PCa. In silico reanalysis of genes with known involvement in vesicular trafficking and secretion in an existing microarray dataset revealed low expression of RAB27A, RAB27B and VPS36 to be predictive for reduced BCR-free survival in patients with localized PCa (p=0...

BACKGROUND: Early-stage lung cancer represents a key focus of numerous multicenter clinical trials, but common exclusion criteria such as a prior cancer diagnosis may limit enrollment. We examined the prevalence and prognostic impact of a prior cancer diagnosis among patients with early-stage lung cancer. METHODS: We identified patients>65 years of age with early-stage lung cancer diagnosed 1996-2009 in the Surveillance, Epidemiology, and End Results-Medicare linked database...

A 63-year-old man with a history of prostate cancer, treated with resection, radiation, and androgen-depriving therapy over 4 years, was referred to our department with suspicion of recurrence based on increased blood PSA levels (1.60 ng/mL). Ga PSMA PET/CT identified a solitary, PSMA-positive pulmonary nodule in the right lung. After resection, histologic analysis confirmed prostatic origin, and the blood PSA level decreased to 0.13 ng/mL. Solitary pulmonary metastasis from prostate cancer is rare. The benefits of local treatment of a single metastasis even in advanced disease are disputed among oncologists...

CONTEXT: Recent demonstration of efficacy with the use of chemohormonal therapy for men with metastatic prostate cancer (mPCa) has expanded the therapeutic options for these patients. Furthermore, multimodal therapy to treat systemic disease in the context of locoregional control has gained increasing interest. Concomitantly, the role of radical prostatectomy (RP) in multimodal treatment for locally advanced prostate cancer is expanding. As a result, there is interest in investigating the potential benefit of cytoreductive RP in mPCa...

Dairy intake has been associated with increased risk of advanced prostate cancer. Two US cohort studies reported increased prostate cancer-specific mortality with increased high-fat milk intake. We examined whether dairy and related nutrient intake were associated with prostate cancer progression in a Swedish patient population with high dairy consumption. We prospectively followed 525 men with newly diagnosed prostate cancer (diagnosed 1989-1994). We identified and confirmed deaths through February 2011 (n = 222 prostate cancer-specific, n = 268 from other causes)...
