PURPOSE To describe patterns of recurrence of elective nodal irradiation (ENI) in definitive chemoradiotherapy (CRT) for thoracic esophageal squamous cell carcinoma (SqCC) using 3D-conformal radiotherapy. METHODS AND MATERIALS One hundred and twenty-six consecutive patients with stages I-IVB thoracic esophageal SqCC newly diagnosed between June 2000 and(More)
PURPOSE The expressions of six cell-cycle-associated proteins were analyzed in cervical squamous cell carcinomas in correlation in a search for prognostic correlations in tumors treated with concurrent chemoradiation therapy (cCRT). METHODS AND MATERIALS The expressions of p53, p21/waf1/cip1, molecular immunology borstel-1 (MIB-1), epidermal growth factor(More)
PURPOSE To determine the risk factors of severe radiation pneumonitis (RP) after stereotactic body radiation therapy (SBRT) for primary or secondary lung tumors. MATERIALS AND METHODS From January 2003 to March 2009, SBRT was performed on 117 patients (32 patients before 2005 and 85 patients after 2006) with lung tumors (primary = 74 patients and(More)
PURPOSE To investigate the three-dimensional movement of internal fiducial markers placed near esophageal cancers using 320-multislice CT. METHODS AND MATERIALS This study examined 22 metal markers in the esophageal wall near the primary tumors of 12 patients treated with external-beam photon radiotherapy. Motion assessment was analyzed in 41 respiratory(More)
PURPOSE To study the three-dimensional movement of internal tumor bed fiducial and breast skin markers, using 320-multislice computed tomography (CT); and to analyze intrafractional errors for breast cancer patients undergoing breast irradiation. METHODS AND MATERIALS This study examined 280 markers on the skin of the breast (200 markers) and on the(More)
AIM A review was conducted in which the effect of age on survival was assessed in a population of endometrial cancer patients treated with surgery and adjuvant radiation therapy in our institution. METHODS From 1988 to 2008, 111 endometrial cancer patients underwent total abdominal hysterectomy and adjuvant whole pelvic radiation therapy (RT). After(More)
OBJECTIVE To quantify the effect of bladder volume on the dose distribution of intracavitary brachytherapy in computed tomography-based treatment planning for cervical cancer. METHODS Ten patients with cervical cancer were treated with high-dose rate radiation brachytherapy. For the three-dimensional analysis, pelvic computed tomographic scans were(More)
INTRODUCTION Cancer-related fatigue greatly influences quality of life in cancer patients; however, no specific treatments have been established for cancer-related fatigue, and at present, no medication has been approved in Japan. Systematic research using patient-reported outcome to examine symptoms, particularly fatigue, has not been conducted in(More)
BACKGROUND This retrospective study was conducted to compare the treatment and quality of life (QOL) results between radical surgery and definitive chemoradiotherapy (CRT) for stage II-III carcinoma of the esophagus. METHODS Between 2000 and 2009, 128 consecutive patients were selected for this study in which 72 were treated with definitive CRT and 56(More)
INTRODUCTION The abscopal effect is the effect of radiation therapy at a site distant to the area of irradiation. This is not a common event and has not been clearly defined, resulting in few reported cases in the literature. We discuss this phenomenon in a patient with hepatocellular carcinoma. CASE PRESENTATION A 63-year-old Japanese man underwent(More)
