LungBEAM: A prospective multicenter study to monitor stage IV NSCLC patients with EGFR mutations using BEAMing technology
2021
Abstract Objectives The aim of LungBEAM was to determine the value of a novel epidermal growth factor receptor (EGFR) mutation test in blood based on BEAMing technology to predict disease progression in advanced non‐small cell lung cancer (NSCLC) patients treated with first‐ or second‐generation EGFR‐tyrosine kinase inhibitors (EGFR‐TKIs). Another goal was to monitor the dynamics of EGFR mutations, as well as to track EGFR exon 20 p.T790M (p.T790M) resistance during treatment, as critical indicators of therapeutic efficacy and patient survival. Methods Stage IV NSCLC patients with locally confirmed EGFR‐TKI sensitizing mutations (ex19del and/or L858R) in biopsy tissue who were candidates to…
Venous Thromboembolism Risk in Patients With Locoregional Urothelial Tract Tumors
2017
Data de publicació electrónica: 24-08-2017 BACKGROUND: Venous thromboembolism (VTE) is common in cancer patients, but there is limited data on patients with urothelial tract tumors (UTT). We previously identified several associative factors for increased VTE rates in patients with metastatic UTT. In this study, we assessed the frequency, associative factors, and impact on survival of VTE in patients with locoregional UTT. METHODS: Patients with locoregional bladder, upper urinary tract, or urethral cancer were included in this multi-center study from 29 academic institutions. Patients with N1, or M1 disease at diagnosis were excluded. Patients with incomplete clinical staging or miscoded/mi…
A Mumford-Shah functional based variational model with contour, shape, and probability prior information for prostate segmentation
2012
Abstract: Inter patient shape, size and intensity variations of the prostate in transrectal ultrasound (TRUS) images challenge automatic segmentation of the prostate. In this paper we propose a variational model driven by Mumford-Shah (MS) functional for segmenting the prostate. Parametric representation of the implicit curve is derived from principal component analysis (PCA) of the signed distance representation of the labeled training data to impose shape prior. Posterior probability of the prostate region determined from random forest classification facilitates initialization and propagation of our model in a MS energy minimization framework. The proposed method achieves mean Dice simila…
La comunicació del càncer infantil i juvenil a Espanya (1960-2017). Una anàlisi a través de la premsa i d'Internet
2019
Els mitjans de comunicació contribueixen a crear la imatge que, com a societat, tenim d’una malaltia. El càncer en adults ha estat analitzat des de diverses disciplines, inclosa la comunicació. Menys investigada ha estat aquesta malaltia en la població infantil i adolescent. El càncer pediàtric ha adquirit importància, de manera progressiva, en les darreres dècades. Prova d’això són la quantitat d’estudis mèdics sobre el tema però també, des d’un punt de vista més social, els treballs realitzats des de l’antropologia o la psicologia. En comunicació, tanmateix, encara és escassa la literatura que analitza el càncer infantil en mitjans de comunicació com la televisió o la premsa. Encara hi ha…
Entre l’estigma i la frivolitat: El Dia Mundial del Càncer en la premsa espanyola
2013
El càncer és un tema d’interès destacat per a la ciutadania. Els mitjans de comunicació, en tant que reflex i alhora conformadors de valors socials, transmeten una visió de la malaltia que no sempre és la més acurada i clarificadora. En aquest article s’analitza la repercussió mediàtica durant la darrera dècada del Dia Mundial del Càncer als quatre diaris d’informació general amb major difusió a Espanya. L’objectiu és estudiar de quina manera es fa ús de l’efemèride per a oferir informació relativa a la malaltia i si el tractament informatiu és precís i rigorós o cau en l’estereotip i el sensacionalisme.
Quality Analysis of YouTube Videos Presenting Pelvic Floor Exercises after Prostatectomy Surgery
2021
Background: Prostate cancer (PC) is a major cause of disease and mortality among men. Surgical treatment involving the removal of the prostate may result in temporary or permanent erectile dysfunction (ED) and urinary incontinence (UI), with considerable impact on quality of life. Pelvic floor muscle training (PFMT) is one of the recommended techniques for the prevention, treatment, and rehabilitation of postoperative complications. The aim of this observational study was to assess the quality of YouTube videos—accessible to any patient—related to exercises after prostatectomy surgery. Methods: A systematic search was performed on YouTube on 24 September 2020. One hundred and fifty videos w…
Mediterranean Diet and Invasive Breast Cancer Risk Among Women at High Cardiovascular Risk in the PREDIMED Trial
2015
Importance Breast cancer is the leading cause of female cancer burden, and its incidence has increased by more than 20% worldwide since 2008. Some observational studies have suggested that the Mediterranean diet may reduce the risk of breast cancer. Objective To evaluate the effect of 2 interventions with Mediterranean diet vs the advice to follow a low-fat diet (control) on breast cancer incidence. Design, Setting, and Participants The PREDIMED study is a 1:1:1 randomized, single-blind, controlled field trial conducted at primary health care centers in Spain. From 2003 to 2009, 4282 women aged 60 to 80 years and at high cardiovascular disease risk were recruited after invitation by their p…
