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…

Nanostructured Lipid Carriers-Containing Anticancer Compounds: Preparation, Characterization, and Cytotoxicity Studies

2007

This article describes the development of nanostructured lipid carriers (NLC) as colloidal carriers for two antitumor compounds that possess a remarkable antineoplastic activity. But their limited stability and low solubility in water could give a very low parenteral bioavailability. Results revealed an enhancement of the cytotoxicity effect of drug-loaded NLC on human prostate cancer (PC-3) and human hepatocellular carcinoma (HuH-6, HuH-7) cell lines with respect to that of both free drugs. Results of characterization studies strongly support the potential application of these drugs-loaded NLC as prolonged delivery systems for lipophilic drugs by several administration routes, in particula…

SU-E-T-530: Comparison of Analytical and Monte Carlo Calculations for Heterogeneity Corrections in LDR Prostate Brachytherapy

2013

Purpose: It is well‐known that tissue heterogeneities and calcifications have significant influence on low energy brachytherapy. The aim of this work is to study the application of a simplified analytic algorithm that could be compatible with commercial Treatment Planning System (TPS) based on TG‐43. The algorithm, based on the classic equivalent path length method, has been compared with Monte Carlo (MC) computations using Penelope2009. Methods: The analytical model scales the distance from the seed to the calculation point according to the electronic density of the medium relative to water. Then, the dose is calculated from TG‐43 consensus data (stored on a TPS) by scaling the radial dose…

DIAGNOSTIC ACCURACY OF IXIP INDEX AND PROSTATE MRI IN THE DIAGNOSIS OF PROSTATE CANCER: PRELIMINARY RESULTS ON A COMBINED APPROACH

2021

The purpose of this study was to assess whether Immune CompleX Predictive Index (iXip) improves diagnostic accuracy of multiparametric prostate MRI (mpMRI) for clinically significant prostate cancer. This study included 72 patients (mean age: 68±8 years) with suspicion of prostate cancer and available iXip score. mpMRI images were evaluated by two radiologists according to the PI-RADS v2.1. Reference standard was based on fusion biopsy and standard transperineal 12-point biopsy. Diagnostic accuracy of iXip, mpMRI and their combination were calculated. Optimal cutoff of iXip with sensitivity and specificity was identified using the Youden index. Patients with clinically significant prostate …

Comparison of Fluoroquinolones and Other Antibiotic Prophylaxis Regimens for Preventing Complications in Patients Undergoing Transrectal Prostate Bio…

2022

Our study aimed to compare the incidence of infective complications after transrectal ultrasound-guided prostate biopsy (TRUSBx) when adopting different antimicrobial prophylaxis regimens. A multi-institutional cohort of 1150 patients who underwent TRUSBx was retrospectively analyzed. Procedures were performed between 2017 and 2019 (before and after the EMA warning about the use of fluoroquinolones for the antibiotic prophylaxis of patient candidates to TRUSBx). The primary endpoint was the occurrence of infective complications, including sepsis and/or fever. The population was stratified according to the antibiotic prophylaxis adopted: fluoroquinolones (levofloxacin, ciprofloxacin, prulifl…

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…
