PURPOSE This study aimed to investigate whether metabolic tumor volume (MTV) measured from [(18)F]-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) predicts short-term outcome to radiotherapy with or without chemotherapy and disease-free survival (DFS) in patients with pharyngeal cancers. EXPERIMENTAL DESIGN The MTVs of(More)
UNLABELLED In this retrospective study, we investigated whether the (18)F-FDG uptake pattern and CT findings improved the accuracy over the standardized uptake value (SUV) for differentiating benign from malignant focal thyroid lesions incidentally found on (18)F-FDG PET/CT. We also defined the prevalence of these lesions and their risk for cancer. (More)
In our previous study, we clearly demonstrated the roles of pro-inflammatory cytokines, including tumor necrosis factor-alpha, interleukin-1beta (IL-1beta), and IL-6, and subsequent reactive oxygen species (ROS) generation on the pathogenesis of cisplatin ototoxicity in vitro and in vivo. ROS generation in cisplatin-treated HEI-OC1 auditory cells was also(More)
OBJECTIVE To compare the diagnostic accuracy of integrated 18F-fluorodeoxyglucose PET/CT with ultrasonography (US) and contrast enhanced CT (CECT) alone in the initial evaluation of cervical lymph node levels of patients with papillary thyroid carcinoma. PATIENTS AND MEASUREMENTS From July 2004 to March 2005, 26 consecutive patients with papillary thyroid(More)
INTRODUCTION Since the introduction of laparoscopic surgery, surgeons have not only been concerned about clinical outcomes, but also surgical scars. Although natural orifice transluminal endoscopic surgery (NOTES) is promising, it is not applicable to clinical practice thus far due to safety concerns. As a transitional procedure between standard(More)
UNLABELLED The purpose of this study was to investigate the clinical usefulness of PET/CT or CT-attenuated PET in the evaluation of patients with oral cavity cancer (OCC) in whom dental artifacts distorted the conventional CT or MR images of the oral cavity. METHODS A PET/CT scan, in addition to a CT or MRI scan, was performed in 69 patients with OCC who(More)
PURPOSE Primary tumors of the retrorectal space in adults are very rare. Most of them are benign masses, but malignant masses are reported on occasion. This study aimed to investigate the clinicopathological features of retrorectal tumors. METHODS The medical records of fifteen patients who underwent surgical resection of a retrorectal tumor from March(More)
Dysfunction in immune surveillance during anticancer chemotherapy of patients often causes weakness of the host defense system and a subsequent increase in microbial infections. However, the deterioration of organ-specific function related to microbial challenges in cisplatin-treated patients has not yet been elucidated. In this study, we investigated(More)
The inhibitory effects of tanshinone IIA, a diterpene isolated from Salvia miltiorrhiza root, on the production of nitric oxide (NO), interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha), and the expression of inducible nitric oxide synthase (iNOS) were investigated in activated RAW 264.7 cells. This compound(More)
