BACKGROUND The aim of this phase 2 study was to determine the long-term local control, survival, and late toxicities among patients with locally advanced nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT) with the simultaneous modulated accelerated radiation therapy (SMART) boost technique and concurrent chemotherapy.

PURPOSE A prospective, randomized, phase III study was performed to evaluate the feasibility and efficacy of concurrent weekly oxaliplatin with radiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS From January 2001 to January 2003, 115 patients with locoregionally advanced NPC were randomly assigned to(More)
OBJECTIVE Mitochondrial biology appears central to many conditions that progress to death but remains poorly characterized after cardiac arrest. Mitochondrial dysfunction in electron transfer and reactive oxygen species leakage during ischemia may lead to downstream events including mitochondrial protein oxidation, tyrosine nitrosylation, cytochrome c loss,(More)
The Mre11/Rad50/NBS1 (MRN) complex is thought to be a critical sensor that detects damaged DNA and recruits ATM to DNA foci for activation. However, it remains to be established how the MRN complex regulates ATM recruitment to the DNA foci during DNA double-strand breaks (DSBs). Here we show that Skp2 E3 ligase is a key component for the MRN(More)
BACKGROUND AND PURPOSE To evaluate the long-term survival outcomes and toxicity of NPC patients treated with intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS From May 2001 to October 2008, 868 non-metastatic NPC patients treated by IMRT were analyzed retrospectively. The Radiation Therapy Oncology Group (RTOG) criteria were used to assess(More)
BACKGROUND Blood oxygen level-dependent MRI (BOLD MRI) can be used to assess intra-renal oxygen bioavailability by measuring the R2(*) level, which reflects tissue deoxyhaemoglobin levels. This study was designed to identify the significance of BOLD MRI in differentiation of acute rejection (AR) and acute tubular necrosis (ATN) in patients within 6 months(More)
BACKGROUND The use of emergency cardiopulmonary bypass (ECPB) resuscitation after cardiac arrest may offer hope for survival when standard ACLS therapies fail. However, whether cooling adds benefit to ECPB is unknown and we lack an ECPB rodent model for experimental studies. We sought to (a) develop a 72 h survival rodent model using ECPB to treat asphyxial(More)
AIMS To analyse the outcomes and to evaluate the prognostic factors involved in the re-irradiation of locally recurrent nasopharyngeal carcinoma (NPC) using intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS A retrospective analysis of 239 NPC patients with local recurrence who were re-irradiated with IMRT between 2001 and 2008 was conducted.(More)
OBJECTIVE To identify whether the presence and/or timing of rapid eye movement (REM) sleep behavior disorder (RBD) onset were associated with differences in clinical features and sleep parameters of Parkinson disease (PD). METHODS In all, 112 PD patients were enrolled and all underwent extensive clinical evaluations and video-polysomnography (PSG).(More)
PURPOSE Reports of intensity-modulated radiotherapy (IMRT) for early-stage nasopharyngeal carcinoma (NPC) have been limited. The present study evaluated the long-term survival outcomes and toxicity of early-stage NPC patients treated with IMRT alone. METHODS AND MATERIALS Between February 2001 and January 2008, 198 early-stage (T1-T2bN0-N1M0) NPC patients(More)
