BACKGROUND The aim of this study was to investigate the feasibility of involved-field irradiation (IFI) for the treatment of cervical and upper-thoracic esophageal cancer with concurrent chemoradiation. PATIENTS AND METHODS 102 eligible patients with cervical or upper-thoracic esophageal cancer were treated with concurrent chemoradiation and randomized to(More)
AIMS AND BACKGROUND The purpose of the research was to study the prognostic value of tumor 18F-FDG PET-based parameters in neoadjuvant chemoradiation for patients with squamous esophageal carcinoma. METHODS Sixty patients received chemoradiation therapy followed by esophagectomy and two 18FDG-PET examinations at pre- and post-radiation therapy. PET-based(More)
AIM To evaluate the efficacy and safety of late-course hypofractionated radiation treatment of muscle-invasive bladder carcinoma after bladder-conserving surgery. METHODS Seventy-six patients with transitional cell bladder carcinoma, stage II (T2-4N0M0), after transurethral resection, were enrolled. Pirarubicin was given at 30 mg/m2 and 100 mL(More)
OBJECTIVE To present and discuss the clinical features, treatment, and efficacy of pyriform sinus carcinoma involving the lateral wall. METHODS Seventy-seven patients with pyriform sinus cancer involving the lateral wall (stage I 8, stage II 10, stage III 32, stage IV 27, according to UICC 2002 staging) were treated from Jun 1997 to Jun 2009 in the(More)
AIMS To prospectively assess the efficacy and safety of moderately hypofractionated conformal radiotherapy in patients with thoracic esophageal cancer. METHODS AND MATERIALS From Sept. 2002 to Oct. 2005, 150 eligible patients with T2-4N0-1M0 stage thoracic esophageal squamous cell cancers were enrolled to receive either conventional fractionated radiation(More)
We investigate two different kinds of resonant current regulators for a doubly fed induction generator (DFIG) under distorted grid voltage conditions: proportional integral resonant (PIR) regulator with traditional resonant part and vector proportional integral (VPI) regulator with VPI resonant part. Based on the mathematical model of DFIG under distorted(More)
This paper presents a multiple target implementation technique for a doubly fed induction generator (DFIG) under unbalanced and distorted grid voltage based on direct power control (DPC). Based on the mathematical model of DFIG under unbalanced and distorted voltage, the proportional and integral (PI) regulator is adopted to regulate the DFIG average active(More)
PURPOSE The aims of this trial were to study whether a decreased percentage of tumor fluorodeoxyglucose (FDG) uptake (%DeltaSUVmax) correlated with overall survival and local control times for patients with esophageal cancer and which patients would benefit from a late-course accelerated hyperfractionated (LCHF) radiation scheme.
