OBJECTIVE To determine an appropriate threshold value for delineation of the target in positron emission tomography (PET) and to investigate whether PET can delineate an internal target volume (ITV), a series of phantom studies were performed. METHODS An ellipse phantom (background) was filled with 1028 Bq/ml of [(18)F] fluoro-2-deoxyglucose ((18)FDG),(More)
To visualize intratumoral hypoxic areas and their reoxygenation before and during fractionated radiation therapy (RT), (18)F-fluoromisonidazole positron emission tomography and computed tomography (F-MISO PET/CT) were performed. A total of 10 patients, consisting of four with head and neck cancers, four with gastrointestinal cancers, one with lung cancer,(More)
OBJECTIVE The aim of this study was to analyze the clinical results of our adaptive radiation therapy scheme of a two-step intensity-modulated radiotherapy (IMRT) method for nasopharyngeal cancer (NPC) at Kinki University Hospital. METHODS Between 2000 and 2007, 35 patients with Stage I-IVB NPC treated by IMRT were included. For all patients,(More)
OBJECTIVE The purpose of this retrospective study was to analyze the results of accelerated hyperfractionation for patients with moderately advanced (T2 and T3) laryngeal cancer. METHODS Between 1998 and 2007, 9 supraglottic carcinomas (6 T2N0M0, 2 T2N2M0, 1 T3N0M0), 30 glottic carcinomas (25 T2N0M0, 5 T3N0M0), and 1 T2N0M0 subglottic carcinoma were(More)
