PURPOSE The neutrophil-lymphocyte ratio (NLR) has been suggested as an inflammation-related factor, but also as an indicator of systemic anti-tumor immunity. We aimed to evaluate the prognostic value of the NLR and to propose a proper cut-off value in patients with locally advanced rectal cancer who received preoperative chemoradiation (CRT) followed by curative total mesorectal excision (TME)....
Abstract Background Cardiac resynchronization therapy (CRT) is hampered by a relative high rate of non-response whereby device optimization could aid in improving benefit from CRT. Nonetheless, non-invasive and reproducible clinical tool for currently lacking. Recently introduced cardiovascular magnetic resonance (CMR) compatible CRT devices may allow patient follow-up as biventricular (BIV) pa...
BACKGROUND Cardiac implantable electric devices are commonly used to treat heart failure. Little is known about temporal and geographic variation in use of cardiac resynchronization therapy (CRT) devices in usual care settings. METHODS AND RESULTS We identified new CRT with pacemaker (CRT-P) or defibrillator generators (CRT-D) implanted between 2008 and 2013 in the United States from a commer...
Background and study aims Salvage therapy for esophageal cancer following chemo-radiation therapy (CRT) has not been established. We aimed to evaluate endoscopic submucosal dissection (ESD) as a salvage therapy based on histopathological features of lesions. Patients and methods We compared 10 lesions in eight patients with local residual, recurrent, or metachronous esophageal squamous cell...
Purpose: In the current study, using different radiobiological models, tumor control probability (TCP) and normal tissue complication probability (NTCP) of radiotherapy plans were calculated for three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT) of prostate cancer.Methods and Materials: 10 prostate plans were randomly selected among patients ...
BACKGROUND To investigate serum carcinoembryonic antigen (CEA) as a prognostic factor for rectal cancer patients receiving pre-operative chemoradiotherapy (CRT). METHODS Between 2000 and 2009, 138 patients with advanced rectal cancer receiving CRT before surgery at our hospital were retrospectively classified into 3 groups: pre-CRT CEA <6 ng/ml (group L; n = 87); pre-CRT CEA ≥ 6 ng/ml and pos...
AbstractBackground There is limited evidence on the influence of sex decision to implant a cardiac resynchronization therapy device with pacemaker (CRT-P) or defibrillator (CRT-D) and existence sex-dependent differences in complications that may affect this decision. Methods All patients undergoing de novo CRT implantation (2004-2014) United States National Inp...
AIMS The choice of resynchronization therapy between with (CRT-D) and without (CRT-P) a defibrillator remains a contentious issue. Cause-of-death analysis among CRT-P, compared with CRT-D, patients could help evaluate the extent to which CRT-P patients would have additionally benefited from a defibrillator in a daily clinical practice. METHODS AND RESULTS A total of 1705 consecutive patients ...
Post-translational arginylation consists of the covalent union of an arginine residue to a Glu, Asp, or Cys amino acid at the N-terminal position of proteins. This reaction is catalyzed by the enzyme arginyl-tRNA protein transferase. Using mass spectrometry, we have recently demonstrated in vitro the post-translational incorporation of arginine into the calcium-binding protein calreticulin (CRT...
