Musculoskeletal Responses to Exercise Plus Nutrition in Men with Prostate Cancer on Androgen Deprivation: A 12-Month RCT

2021

PURPOSE Androgen deprivation therapy (ADT) for prostate cancer has multiple adverse effects on musculoskeletal health. This 12-month randomized controlled trial aimed to assess the effects of multicomponent exercise training combined with whey protein, calcium and vitamin D supplementation on bone mineral density (BMD), structure and strength, body composition, muscle strength, and physical function in ADT-treated men. METHODS Seventy ADT-treated men were randomized to exercise plus supplementation (Ex + Suppl; n = 34) or usual care (control; n = 36). Ex + Suppl involved thrice weekly progressive resistance training plus weight-bearing impact exercise with daily multinutrient supplementatio…

Choline PET/CT Features to Predict Survival Outcome in High Risk Prostate Cancer Restaging: A Preliminary Machine-Learning Radiomics Study

2020

Background Radiomic features are increasingly utilized to evaluate tumor heterogeneity in PET imaging but to date its role has not been investigated for Cho-PET in prostate cancer. The potential application of radiomics features analysis using a machine-learning radiomics algorithm was evaluated to select 18F-Cho PET/CT imaging features to predict disease progression in PCa. Methods We retrospectively analyzed high-risk PCa patients who underwent restaging 18F-Cho PET/CT from November 2013 to May 2018. 18F-Cho PET/CT studies and related structures containing volumetric segmentations were imported in the "CGITA" toolbox to extract imaging features from each lesion. A Machine-learning model h…

Multiparametric MRI and post implant CT-based dosimetry after prostate brachytherapy with iodine seeds: The higher the dose to the dominant index les…

2015

Abstract Purpose To determine whether post-implant MRI-based dosimetry of the Dominant Intra-prostatic Lesion (DIL) could best predict the occurrence of PSA bounce after prostate brachytherapy. Methods and materials We selected 66 patients with a low risk prostate cancer treated with 125 I prostate brachytherapy as monotherapy. Post-implant dosimetry based on day 30 CT-scan and multiparametric MRI co-registration was generated: planned D 90, D 95, V 100, V 150 values were calculated for each DIL. Bounce was defined as a PSA elevation ⩾0.2ng/mL from the previous baseline value followed by a decrease to or below the prior nadir with no additional treatment. Results After a median follow-up of…

Predicting trajectories of recovery in prostate cancer patients undergone Robot-Assisted Radical Prostatectomy (RARP)

2019

ObjectiveTo identify trends of patients' urinary and sexual dysfunctions from a clinical and psychological perspective and understand whether sociodemographic and medical predictors could differentiate among patients following different one-year longitudinal trajectories.MethodsAn Italian sample of 478 prostate cancer patients undergone Robot-Assisted Radical Prostatectomy completed the EPIC-26 survey between July 2015 and July 2016 at the pre-hospitalization (T0), 45 days (T1) and 3 (T2), 6 (T3), 9 (T4), and 12 months (T5) after surgery. Sociodemographic and clinical characteristics (age, BMI, diabetes, nerve-sparing procedure) were also collected. Latent Class Growth Analysis was conducte…

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…

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 …
