The diagnostic possibilities of Positron Emission Tomography (PET)
2014
Se describen los principios de la tomografía por emisión de positrones (PET) como procedimiento diagnóstico de reciente introducción en el campo de las Ciencias de la Salud. Las aplicaciones clínicas principales se dan en un grupo concreto de especialidades: la cardiología, neurología, psiquiatría y sobre todo la oncología. La tomografía por emisión de positrones es una técnica de diagnóstico por la imagen no invasiva de uso clínico. Se trata de una excelente herramienta para el estudio de la estadificación y la posible malignización de los tumores de cabeza y cuello, la detección de metástasis y linfoadenopatías no valorables clínicamente, así como para el diagnóstico de recidivas tumorale…
Cervical intraepithelial neoplasia (CIN) in pregnancy: The state of the art
2014
Cervical cancer is the most commonly diagnosed malignancy in pregnancy and cervical screening should be accordingly performed in this particular situation. Occurrence of a preneoplastic cervical disease in pregnancy has for a long time represented a challenge for the clinician, both in terms of diagnostic accuracy, treatment options and risk of obstetrical complications. For these reasons, lack of uniformity in diagnosis and management is still commonly observed and the need for evidence-based clarifications is strongly required. Consistently with the literature evidences and accordingly with international guidelines, this review aim to overview the most significant aspects of the issue and…
Edad, creencias de salud y asistencia a un programa de cribado mamográfico en la comunidad valenciana
2004
Yolanda Andreu Vaillo, Mª José Galdón Garrido, Estrella Durá Ferrandis, Stephanie Carretero Gómez (yolanda.andreu@uv.es) La edad influye significativamente en las creencias de salud relacionadas con la asistencia a programas de cribado mamográfico. El objetivo de este trabajo es analizar las creencias y actitudes hacia el cáncer de mama asociadas a la asistencia a un programa de cribado en diferentes grupos de edad.Métodos: Utilizando un diseño transversal se comparan las creencias de salud de un grupo de mujeres que acuden a un programa de cribado con las de las mujeres que no lo hacen, considerando tres intervalos de edad: menores de 50 años (N=279), 50-60 años (N=463), mayores de 60 (N=2…
Cancer prevention with aspirin in hereditary colorectal cancer (Lynch syndrome), 10-year follow-up and registry-based 20-year data in the CAPP2 study…
2020
BACKGROUND: Lynch syndrome is associated with an increased risk of colorectal cancer and with a broader spectrum of cancers, especially endometrial cancer. In 2011, our group reported long-term cancer outcomes (mean follow-up 55·7 months [SD 31·4]) for participants with Lynch syndrome enrolled into a randomised trial of daily aspirin versus placebo. This report completes the planned 10-year follow-up to allow a longer-term assessment of the effect of taking regular aspirin in this high-risk population.METHODS: In the double-blind, randomised CAPP2 trial, 861 patients from 43 international centres worldwide (707 [82%] from Europe, 112 [13%] from Australasia, 38 [4%] from Africa, and four [&l…
Atypical epithelial hyperplasia of the breast: state of the art.
2016
International audience; Introduction: Atypical epithelial hyperplasia (AEH) of the breast is considered benign histological lesions with breast cancer risk. This review focuses on clinical signification and management of AEH that remains controversial. Areas covered: A review of published studies was performed using medline database. In this review, we fully describe the current evidence available. In particular, we describe 1) data from immunohistochemistry and molecular studies that suggest AEH is a precursor of breast cancer; 2) epidemiological studies demonstrate low rate of breast cancer in women with AEH; 3) surgical excision is necessary after diagnosis of AEH, such as lobular carcin…

Metilazione del DNA in artrite reumatoide
2005
Lo stato di metilazione del DNA genomico e del gene PTHrP è stato valutato con tecniche molecolari e citogenetiche in artrite reumatoide (AR), patologia autoimmune caratterizzata anche da alta incidenza di linfomi e da ipercalcemia per overespressione del gene PTHrP. La metilazione del DNA, infatti, ha un ruolo critico nello sviluppo delle malattie neoplastiche; il gene PTHrP avendo tre promotori uno dei quali contiene un’isola CpG è un buon candidato per la deregolazione da alterato pattern di metilazione locale. Le indagini sulla metilazione genomica, condotte su DNA estratto da sangue periferico di pazienti e di donatori e amplificato in reazioni di Methylation-Sensitive Arbitrarily Prim…
