The management of bone lesions from advanced solid tumors and multiple myeloma typically includes use of a bone-modifying agent to reduce the risk of skeletal-related events. Recent data demonstrate that when using zoledronic acid to reduce the risk of skeletal-related events in metastatic breast cancer, metastatic prostate cancer, and multiple myeloma, the dosing interval of zoledronic acid may be extended from every 4 weeks to every 12 weeks. The ASCO guidelines on the role of bone-modifying agents in metastatic breast cancer and multiple myeloma address zoledronic acid dosing intervals...

BACKGROUND: Skeletal-related events (SREs), common sequelae of metastatic cancer, are reduced by bisphosphonates. In this study, it was postulated that radiopharmaceuticals, added to bisphosphonates, could further decrease the incidence of SREs. METHODS: NRG Oncology RTOG 0517 randomized patients with breast, lung, and prostate cancer and blastic bone metastases to either zoledronic acid (ZA) alone or ZA plus radiopharmaceuticals (Sr-89 or Sm-153). The primary endpoint was time to development of SREs...

INTRODUCTION: In castration-resistant prostate cancer (CRPC), early detection of metastases is essential for the selection of treatment, and prevention of bone complications. However detecting incipient metastases remains a challenge as the conventional radiological tests (bone scintigraphy or computerised tomography) lack sufficient sensitivity. Diagnostic imaging techniques are currently available that have greater sensitivity and specificity, but are little used due to shortfalls in the recommendations...

Metastasized castration-resistant prostate cancer (mCRPC), is the most advanced form of prostate neoplasia, where massive spread to the skeletal tissue is frequent. Patients with this condition are benefiting from an increasing number of treatment options. However, assessing tumor response in patients with multiple localizations might be challenging. For this reason, many computational approaches have been developed in the last decades to quantify the skeletal tumor burden and treatment response. In this review, we analyzed the progressive development and diffusion of such approaches...

BACKGROUND: Bone is the most predominant site of distant metastasis in prostate cancer(PCa) and patients have limited therapeutic options at this stage. EXPERIMENTAL DESIGN: We performed a system-wide quantitative proteomic analysis of bone metastatic prostate tumors from 22 patients operated to relief spinal cord compression. At the time of surgery, most patients had relapsed after androgen-deprivation therapy, while 5 were previously untreated. An extended cohort of prostate cancer bone metastases (n=65) was used for immunohistochemical validation...

Recently, prostate-specific membrane antigen (PSMA) targeted PET-imaging has emerged as new method of staging and restaging of prostate cancer. Most published studies have investigated the diagnostic potential of 68 Ga-labeled PSMA-agents which are excreted renally. [18 F]PSMA-1007 is a novel PSMA-ligand with excellent preclinical characteristics which is only minimally excreted by the urinary tract, a potential advantage for pelvic imaging. The aim of this study was to investigate the diagnostic efficacy of [18 F]PSMA-1007 in biochemical recurrence (BCR) after radical prostatectomy (RP)...

Introduction: Biochemical relapse (BR) after a primary radical prostatectomy may occur in up to 40 percent of cases. Salvage lymphadenectomy has been proposed in patients with 'node-only' driven BR, following a definitive treatment of primary prostate cancer (PCa). We present our initial series of 10 consecutive patients who underwent an extended robotic salvage pelvic lymph node dissection (eRSPLND) for 'node-only' recurrent PCa. Materials and methods: It was a prospective study, including patients who presented with biochemical relapse after a primary radical prostatectomy at a median of 3...

Skeletal involvement occurs in 30%-70% of all cancer patients, with breast cancer (BC) being the leading cause for bone metastases in women and prostate cancer in men followed by lung cancer. Human immunodeficiency virus (HIV) is a lentivirus (a member of the retrovirus family) that causes acquired immunodeficiency syndrome. It is yet unknown what is the impact of HIV to the onset and progression of bone disease in BC. The purpose of the study was to determine the association of HIV infection and skeletal metastases in BC using skeletal scintigraphy...

Prostate cancer often metastasizes to the bone, leading to morbidity and mortality. While metastasis-associated protein 1 (MTA1) is highly overexpressed in metastatic tumors and bone metastatic lesions, its exact role in the development of metastasis is unknown. Here, we report the role of MTA1 in prostate cancer progression and bone metastasis in vitro and in vivo. We found that MTA1 silencing diminished formation of bone metastases and impaired tumor growth in intracardiac and subcutaneous prostate cancer xenografts, respectively...

Small-cell lung cancer (SCLC) is typically fatal if untreated. It is characterized by early and widespread metastases, and has the ability to rapidly develop resistance to chemotherapy. Bone morphogenetic protein 7 (BMP7), a member of the BMP family of signaling molecules, has been implicated in various types of cancer, particularly prostate cancer and breast cancer. However, there is little knowledge of the function of BMP7 in SCLC. The aim of the present study was to investigate the biological function of recombinant human (rh)BMP7 on SCLC cells and the underlying molecular basis for this regulatory mechanism...

PURPOSE OF REVIEW: The widespread use of prostate-specific antigen (PSA) resulted in stage migration of prostate cancer where androgen deprivation therapy (ADT) is administered for biochemical recurrence in patients following primary treatment. A proportion of these patients progress to a disease state termed nonmetastatic castration-resistant prostate cancer (nmCRPC), with a rising PSA despite ADT and without evidence of metastases on conventional imaging. We will review the treatment options in nmCRPC, especially in light of recent trials showing significant improvement in metastasis-free survival with newer agents...

Prostate adenocarcinoma (PCa) is the most frequently diagnosed malignancy in the male population, with the most common sites for secondary lesions being the lymph nodes, bones, and lungs. Testicular metastases from PCa are very rare and mostly identified incidentally after therapeutic orchiectomy for advanced PCa or during autopsy. Here we present a case involving a 64-year-old man with biochemical recurrence of castrated oligometastatic PCa that presented as solitary testicular metastasis on Ga-PSMA ligand positron emission tomography/computed tomography...

In the course of studies aimed at the role of oxidative stress in the development of metastatic potential in the LNCaP-C4-2B prostate cancer progression model system, we found a relative decrease in the level of expression of the cytoplasmic nicotinamide riboside: quinone oxidoreductase (NQO2) and an increase in the oxidative stress in C4-2B cells compared to that in LNCaP or its derivatives C4 and C4-2. It was also found that C4-2B cells specifically shed large extracellular vesicles (LEVs) suggesting that these LEVs and their cargo could participate in the establishment of the osseous metastases...

Prostate and breast cancers frequently metastasize to bone. The physiological bone homeostasis is perturbed once cancer cells proliferate at the bone metastatic site. Tumors are complex structures consisting of cancer cells and numerous stroma cells. In this study, we show that osteolytic cancer cells (PC-3 and MDA-MB231) induce transcriptome changes in the bone/bone marrow microenvironment (stroma). This stroma transcriptome differs from the previously reported stroma transcriptome of osteoinductive cancer cells (VCaP)...
