Standard Outcome Indicators After Colon Cancer Resection. Creation of a Nomogram for Autoevaluation
2016
Abstract Introduction Lately there has been an increasing interest in identifying quality standards in different pathologies, among them colon cancer due to its great prevalence. The main goal of this study is to define the quality standards of colon cancer surgery based on a large prospective national study dataset. Methods Data from the prospective national study ANACO were used. This study included a consecutive series of patients operated on for colon cancer in 52 Spanish hospitals (2011–2012). Centers with less than 30 patients were excluded. The present analysis finally included 42 centers (2975 patients). Based on the results obtained in 4 main indicators from each hospital (anastomo…
The use of nomograms in LDR-HDR prostate brachytherapy
2011
Purpose: The common use of nomograms in Low Dose Rate (LDR) permanent prostate brachytherapy (BT) allows to estimate the number of seeds required for an implant. Independent dosimetry verification is recommended for each clinical dosimetry in BT. Also, nomograms can be useful for dose calculation quality assurance and they could be adapt ed to High Dose Rate (HDR). This work sets nomograms for LDR and HDR prostate-BT implants, which are applied to three different institutions that use different implant techniques. Material and methods: Patients treated throughout 2010 till April 2011 were considered for this study. This exam ple was chosen to be the representative of the latest implant tech…
The development of a short measure of physical function for knee OA KOOS-Physical Function Shortform (KOOS-PS) – an OARSI/OMERACT initiative
2008
Udgivelsesdato: maj OBJECTIVE: To develop a short measure of physical function for knee osteoarthritis (OA) using multi-national data from individuals with varying degrees of severity of knee OA. METHODS: Rasch analysis, based on the partial credit model, was conducted on Knee injury and Osteoarthritis Outcome Score and Western Ontario McMaster Universities' Osteoarthritis Index data from individuals with knee OA, ranging from community to pre-total knee replacement samples from five countries. Fit of the data to the Rasch model was evaluated by overall model fit and item-level fit statistics (chi(2), size of residual, F-test). Invariance across age, gender and country was evaluated. Unidim…
Radioterapia adapatada al riesgo determinado por test de expresión genética múltiple en estadios iniciales de cáncer de mama y su impacto en el trata…
2020
INTRODUCCIÓN: El cáncer de mama (CM) estadio inicial representa aproximadamente la mitad de las enfermas con receptores hormonales (RH) positivos y sin invasión o con mínima afectación ganglionar locorregional al diagnóstico. El tratamiento adyuvante en estas pacientes se basa en la administración secuencial de radioterapia (RT) adyuvante, quimioterapia (QT) y hormonoterapia o terapia hormonal exclusiva (HT). Numerosos estudios prospectivos han demostrado que la incorporación de los test genómicos a la práctica clínica habitual tiene un impacto significativo en la decisión del tratamiento adyuvante del CM, sin embargo no existe la misma evidencia para los tratamientos locorregionales con ra…
Análisis de nuevos biomarcadores en el cáncer de próstata
2019
La próstata es un órgano interno del aparato reproductor del hombre. y se encarga de producir un fluido que se secreta a la uretra y que formará una parte fundamental del eyaculado por sus propiedades enriquecedoras y protectoras del esperma. Se organiza en tres áreas principales denominadas zona periférica de transición y central. Zona periférica abarca alrededor del 70% del tejido glandular prostático y es donde se localiza el 70-75% de los casos de cáncer de próstata (CaP). El cáncer de próstata (CaP) es la segunda malignidad de órgano sólido más diagnosticada a nivel mundial. Representa la mayor causa de enfermedad y mortalidad para los hombres. Edad, raza, antecedentes familiares y car…
