Preventing bone loss during androgen deprivation therapy for prostate cancer: Early experience with neridronate
2005
Abstract Objective: Androgen-deprivation therapy (ADT) is the usual treatment for locally advanced or metastatic prostate cancer. Osteoporosis is a common complication of ADT. The aim of our study was to evaluate the efficacy of neridronate, a relatively new bisphosphonate to prevent bone loss during androgen ablation. Methods: Sixty patients with prostate cancer and osteoporosis were enrolled and randomly assigned to 2 different treatment regimes: group A (30 patients) treated with maximum androgenic blockage (MAB), and group B (30 patients) treated with bicalutamide 150mg. Each group was divided in 2 subgroups A1–A2 and B1–B2. All patients received calcium and cholecalciferol supplements …
Characterization of C4-2 Prostate Cancer Bone Metastases and Their Response to Castration
2003
New well-characterized preclinical models of prostate cancer (CaP) bone metastases are needed to improve our understanding of the development of CaP-related bone disease in patients. Here we describe characterization of a model consisting of direct injection of C4–2 cells into tibias. Introduction: Prostate cancer (CaP) has a high proclivity to metastasize to bone. Development and characterization of preclinical models of CaP bone metastases are of high interest. The objective of this study was to characterize C4–2 bone metastases and their response to castration. Materials and Methods: Cell suspensions of C4-2, a subline of LNCaP, were injected directly into the tibias of intact male mice.…
Role of abdominal obesity for functional outcomes and complications in men treated with radical prostatectomy for prostate cancer: results of the Mul…
2014
Objective. This study aimed to evaluate the impact of abdominal obesity on preoperative features, complications and functional outcomes of men treated with radical prostatectomy (RP) for prostate cancer. Material and methods. In 2006 a multicentre Italian report on RP evaluated the surgical and functional characteristics of prostate cancer and RP outcomes. Age and waist circumference (WC) were recorded. Abdominal obesity was defined as a WC of at least 102 cm. International Index of Erectile Function (IIEF) score, prostate-specific antigen, prostate volume, tumour characteristics, presence/absence of perioperative complications and the number of blood units transfused were recorded. Preoper…
Oncologic outcome and continence recovery after laparoscopic radical prostatectomy: 3 years' follow-up in a "second generation center".
2006
Objectiues: Laparoscopic radical prostatectomy in major centers guarantees oncologic and functional results equal to open procedures. In our institution this operation was introduced in 2001 after an adequate training in laparoscopic surgery. We report the oncologic and functional results after 3 years of experience.Methods: We considered our first 150 patients that had undergone transperitoneal laparoscopic radical prostatectomy. The following parameters were prospectively collected and analyzed: pathological findings, surgical margins, surgical time, blood loss, hospital stay, catheterization, complications, oncologic follow-up and continence.Results: Single positive surgical margins were…

The Detection of Androgen Receptor Splice Variant 7 in Plasma-derived Exosomal RNA Strongly Predicts Resistance to Hormonal Therapy in Metastatic Pro…
2017
Abstract Background The androgen receptor splice variant 7 (AR-V7) is associated with resistance to hormonal therapy in castration-resistant prostate cancer (CRPC). Due to limitations of the methods available for AR-V7 analysis, the identification of a reliable detection method may facilitate the use of this biomarker in clinical practice. Objective To confirm AR-V7 as a predictor of resistance to hormonal therapy and develop a new approach to assess AR-V7 by highly sensitive digital droplet polymerase chain reaction (ddPCR) in plasma-derived exosomal RNA. Design, setting, and participants Plasma samples were collected from 36 CRPC patients before they began second-line hormonal treatment. …
Comparison of prostate cancer survival in Germany and the USA: can differences be attributed to differences in stage distributions?
2016
Objectives To better understand the influence of prostate-specific antigen (PSA) screening and other health system determinants on prognosis of prostate cancer, up-to-date relative survival (RS), stage distributions, and trends in survival and incidence in Germany were evaluated and compared with the United States of America (USA). Patients and methods Incidence and mortality rates for Germany and the USA for the period 1999-2010 were obtained from the Centre for Cancer Registry Data at the Robert Koch Institute and the USA Surveillance Epidemiology and End Results (SEER) database. For analyses on stage and survival, data from 12 population-based cancer registries in Germany and from the SE…
Permanent seed brachytherapy for clinically localized prostate cancer: long-term outcomes in a 700 patient cohort.
2015
Abstract Purpose Few large European studies have evaluated long-term outcomes for permanent prostate brachytherapy (PPB) as monotherapy for clinically localized prostate cancer. The objective of the present study was to evaluate long-term survival in this patient profile. Methods and Materials Retrospective study of 700 patients who underwent transperineal ultrasound-guided iodine-125 PPB (145 Gy) between January 2000 and July 2012. Median age was 64.8 years (range, 35–79). Most patients (638 of 700; 91%) had low-risk disease (D'Amico criteria). Eighty-five patients (12%) received hormonal treatment. Overall survival, cause-specific survival, and biochemical relapse–free survival were calcu…
Management of Patients with Node-positive Prostate Cancer at Radical Prostatectomy and Pelvic Lymph Node Dissection: A Systematic Review.
2020
Abstract Context Optimal management of prostate cancer (PCa) patients with lymph node invasion at radical prostatectomy and pelvic lymph node dissection still remains unclear. Objective To assess the effectiveness of postoperative treatment strategies for pathologically node-positive PCa patients. The secondary aim was to identify the most relevant prognostic factors to guide the management of pN1 patients. Evidence acquisition A systematic review was performed in January 2020 using Medline, Embase, and other databases. A total of 5063 articles were screened, and 26 studies including 12 537 men were selected for data synthesis and included in the current review according to the Preferred Re…
Moderate hypofractionated helical tomotherapy for prostate cancer in a cohort of older patients: a mono-institutional report of toxicity and clinical…
2019
Purpose or objective: To evaluate toxicity and outcomes of moderately hypofractionated helical tomotherapy for the curative treatment of a cohort of patients aged ≥ 75 years with localized prostate cancer (PC). Materials and methods: From January 2013 to February 2017, 95 patients with median age 77 years (range 75–88) were treated for PC. 39% were low risk, 33% intermediate risk (IR), 28% high risk (HR). Median iPSA was 9.42 ng/ml (1.6–107). Androgen deprivation was prescribed according to NCCN recommendations. All patients received 70 Gy in 28 fractions to the prostate; 61.6 Gy were delivered to the seminal vesicles for IR; whole pelvis irradiation with a total dose of 50.4 Gy was added i…
