INTRODUCTION: Multimodality therapy has curative potential in locally advanced non-small cell lung cancer (LASCLC). Mediastinal nodal sterilization (MNS) after induction chemoradiotherapy (CRT) can serve as an intermediate marker for efficacy. NRG Oncology RTOG 0229 demonstrated the feasibility and efficacy of combining full dose radiation (61.2Gy) with chemotherapy followed by resection and chemotherapy. Based upon that experience and evidence that epidermal growth factor receptor (EGFR) antibodies are radiosensitizing, we explored adding panitumumab to CRT followed by resection and consolidation chemotherapy in LANSCLC with a primary endpoint of MNS...

OBJECTIVES: We examined trends in CRT utilization overall and by sex and race and to assess whether CRT use is associated with a reduction in HF hospitalization and mortality. BACKGROUND: It is unknown whether underutilization and race/sex-based differences in cardiac resynchronization therapy (CRT) use have persisted. The association between CRT and heart failure (HF) hospitalization and mortality in real-world practice remains unclear. METHODS: We linked 72,008 HF patients from 388 hospitals participating in Get With The Guidelines HF eligible for CRT with Centers for Medicare & Medicaid Services data to assess CRT utilization trends, HF hospitalization rates, and all-cause mortality...

Around 12-15% of patients with locally advanced rectal cancer undergo a pathologically complete response (tumor regression grade 4) to long-course preoperative chemoradiotherapy; the remainder exhibit a spectrum of tumor regression (tumor regression grade 1-3). Understanding therapy-related transcriptional alterations may enable better prediction of response as measured by progression-free and overall survival, in addition to aiding the development of improved strategies based on the underlying biology of the disease...

INTRODUCTION: Pulmonary transit time (PTT) assessed with contrast-enhanced ultrasound (CEUS) is a novel tool to evaluate cardiac function. PTT represents the time for a bolus of contrast to pass from the right to the left ventricle, measured according to the indicator dilution principles using CEUS. We investigated the hypothesis that PTT is a measure of general cardiac performance in patient populations eligible for cardiac resynchronization therapy (CRT). METHODS: The study population consisted of heart failure patients referred for CRT with NYHA class II-IV, left ventricular ejection fraction (LVEF)≤35% and QRS≥120 ms...

Aims: Electrical storm (ES) is a condition defined as three or more episodes of ventricular fibrillation (VF) or ventricular tachycardia (VT) within 24 h, and usually coexist with advanced heart failure in patients with structural heart disease. The aim of the present study is to test whether cardiac resynchronization therapy (CRT) can be associated with a lower incidence of ES. Methods and results: The OBSERVO-ICD (NCT02735811) is a multicentre, retrospective registry, enrolling all consecutive patients undergoing ICD or CRT-D implantation from 2010 to 2012 in five Italian high-volume arrhythmia centres...

BACKGROUND: Prediction of which heart failure patients are most likely to die of sudden death vs. non-sudden death is an important factor in determining who will benefit the most from an ICD. OBJECTIVE: We developed the Seattle Proportional Risk Model (SPRM) to estimate the proportion of total mortality due to sudden death. We prospectively validated the model in HF-ACTION and tested whether the ICD benefit varied with the SPRM. METHODS: Among 2331 patients enrolled, 1947 patients were retained for analysis over a median follow-up of 2...

Objective: To investigate the potential dosimetric benefits of four-dimensional computed tomography (4DCT) compared to three-dimensional CT (3DCT) in the planning of radiotherapy for external-beam partial breast irradiation (EB-PBI). Methods: Three-DCT and 4DCT scan sets were acquired for 20 patients who underwent EB-PBI. For each patient a conventional 3D conformal plan (3D-CRT) was generated based on end-inhalation phase (EI). The treatment plan based on the 4DCT EI phase images was copied and applied to the end-exhalation phase (EE) and 3DCT images (defined as EB-PBI(EI), EB-PBI(EE), EB-PBI(3D), respectively)...

Chronic kidney disease (CKD) is associated with worse survival in patients with heart disease including those with implantable devices. Cardiac resynchronization therapy (CRT) can potentially improve renal function. To assess the relation between the change in renal function and survival with CRT, 238 patients undergoing initial CRT with defibrillator implantation between 2002 and 2011 were followed. The primary end point was all-cause mortality. The estimated glomerular filtration rate (eGFR), before implantation and 6 ± 3 months after CRT was calculated...

BACKGROUND: Previous reports suggest that biventricular pacing (BiVp) fused with intrinsic conduction (BiVp-fusion, triple wavefront fusion) is associated with improved resynchronization compared to pure-BiVp in cardiac resynchronization therapy (CRT). This study aimed to assess the association between acute hemodynamic benefit of CRT and signs of BiVp-fusion by using a novel electrogram (EGM)-based method. METHODS: In 17 patients undergoing CRT implantation, 28 combinations of atrioventricular (AV) and interventricular (VV) delays were applied while invasively measuring acute hemodynamic response based on maximum rate of left ventricular (LV) pressure rise (LV dP/dtmax ) to assess optimal BiVp settings...

BACKGROUND: Preoperative concurrent chemoradiation therapy (CRT) with either capecitabine or 5-florouracil/leucovorin (5 FU/LV) is the standard of care in locally advanced rectal cancer (LARC). Literature comparing the toxicity and response of these two regimens in Indian patients is sparse. Our objective was to compare the pathological response (PR) and clinical outcome of capecitabine versus 5 FU/LV in CRT for LARC. MATERIALS AND METHODS: Sixty patients with LARC treated with preoperative CRT with capecitabine or 5FU/LV from January 2009 to May 2014 were analyzed...
