Objective To assess the cost-effectiveness of cardiac resynchronisation therapy (CRT) both with CRT-P (biventricular pacemaker only) and with CRT-D (biventricular pacemaker with defibrillator) in patients with New York Heart Association (NYHA) functional class III/IV from a Belgian healthcare-payer perspective. Methods A lifetime Markov model was designed to calculate the cost-utility of both ...

OBJECTIVES The effect of induction chemoradiotherapy (CRT) on bronchial anastomoses remains uncertain. This prospective study aimed to assess the impact of neoadjuvant CRT on mortality, morbidity and survival following circular sleeve lobectomy (SL). METHODS All consecutive patients undergoing SL between June 2005 and December 2010 were prospectively included. Clinico-demographic variables we...

BACKGROUND The choice of cardiac resynchronization therapy device, with (CRT-D) or without (CRT-P) a defibrillator, in patients with heart failure largely depends on the physician׳s discretion, because it has not been established which subjects benefit most from a defibrillator. METHODS We examined the annual trend of CRT device implantations between 2006 and 2014, and evaluated the factors r...

OBJECTIVES The purpose of this study was to determine the frequency and causes of intermittent and permanent loss of cardiac resynchronization therapy (CRT) in patients who have undergone the successful implantation of a transvenous defibrillator that delivers CRT (CRT-D). BACKGROUND The causes of loss of CRT have not been described. METHODS The records of 512 patients who underwent an atte...

BACKGROUND Although neoadjuvant chemoradiotherapy (CRT) has become a standard procedure to downstage locally advanced rectal cancer prior to surgery, markers to predict the response to CRT have not been fully identified. The aim of this study was to identify predictive factors of response to CRT, especially focusing on peripheral blood leukocyte subsets. METHODS A total of 45 consecutive pati...

Cardiac resynchronization therapy (CRT) for the treatment of heart failure (HF) raises complex problems for informed consent. CRT with and without defibrillator backup has been demonstrated in clinical trials to improve symptoms from HF and decrease mortality.1–4 A CRT pacemaker (CRT-P) may improve symptoms and reduce mortality in selected patients, even without offering the specific protection...

background: the present work aims to study the out-of-field photon calculation accuracy of a commercial treatment planning system (tps), oncentra, for three-dimensional conformal radiotherapy (3d-crt) and intensity modulated radiation therapy (imrt) treatment techniques from elekta synergy medical linear accelerator. materials and methods: accuracy of individual out-of-field dose components was...

Exposure of cancer cells to particular chemotherapeutic agents or γ-irradiation induces a form of cell death that stimulates an immune response in mice. This "immunogenic cell death" requires calreticulin (CRT) translocation to the plasma membrane, which has been shown to promote cancer cell phagocytosis. However, it remains unclear whether the effect of CRT on cancer cell phagocytosis is alone...

AIMS Current imaging techniques attempt to identify responders to cardiac resynchronization therapy (CRT). However, because CRT response may depend upon several factors, it may be clinically more useful to identify patients for whom CRT would not be beneficial even under optimal conditions. We aimed to determine the negative predictive value of a composite echocardiographic index evaluating atr...

Background and objectives: Advanced rectal cancers require local and systemic control. Chemo radiotherapy (CRT) is adequate to achieve adequate local control. Systemic control, however, is a dominant obstacle remained in debates. We compared oncology outcome in both arms in patients with advanced rectal cancers in order to identify high-risk group of distant metastasis. Methods: Data for 723 pa...
