background: this prospective study was conducted to evaluate and compare the efficacies of nasopharyngoscopy and ct scan in the diagnosis of local failure of external beam radiotherapy (ebrt) for nasopharyngeal carcinoma. methods: total 52 patients of histopathologically proven nasopharyngeal carcinoma treated with external beam radiotherapy (ebrt), were included in this study. for every patien...

Background To date no one has examined the quality of life and direct costs of care in treating early stage breast cancer with adjunct intraoperative radiation therapy (IORT) versus external beam radiation therapy (EBRT) over the life of the patient. As well no one has examined the effects of radiation exposure with both therapies on the longer term sequelae. The purpose of this analysis was to...

Purpose/Objectives To evaluate the role of external beam radiation therapy (EBRT) for treatment of malignant paraganglioma (PGL) and pheochromocytoma (PCC). Methods and materials A retrospective review was performed of all patients with malignant PGL/PCC treated with EBRT at our institution between 1973 and 2015. Local control (LC) per treated lesion and overall survival were estimated using ...

BACKGROUND This study assessed the survival outcomes and recurrent patterns in pelvic node-positive IB1-IIA2 cervical cancer patients treated with postoperative external beam irradiation with or without vaginal brachytherapy. METHODS The records of 1149 cervical cancer patients received radical surgery between February 2008 and March 2010 were retrospectively reviewed. 126 stages IB1-IIA2 pat...

AIM To investigate the outcomes for Asian populations with locally advanced/clinical stage III prostate cancer (PCa) treated with currently prevailing modalities. METHODS We reviewed the record of 209 patients with clinical stage III PCa, who were treated at Niigata Cancer Center Hospital between 1992 and 2003. Treatment options included hormone therapy-combined radical prostatectomy (RP+HT),...

PURPOSE For patients undergoing external beam radiation therapy (EBRT) and brachytherapy, recommendations for target doses and constraints are based on calculation of the equivalent dose in 2 Gy fractions (EQD2) from each phase. At present, the EBRT dose distribution is assumed to be uniform throughout the pelvis. We performed a preliminary study to determine whether deformable dose distributio...

• The optimal management of high-risk localised prostate cancer is a major challenge for urologists and oncologists. It is clear that multimodal therapy including radical local treatment is needed in these men to achieve the best outcomes. • External beam radiotherapy (EBRT) is an essential component of therapy either as a primary or adjuvant treatment. However, the role of radical prostatectom...

Fifty-three patients with biochemical relapse (BCR) after receiving external beam radiotherapy (EBRT) against locally advanced prostate cancer (stage III : International Union Against Cancer [UICC] 6th edition) between September 1997 and January 2006 at our institution, who were treated with salvage hormonal therapy (HTx), were followed for a mean period of 75.5 months. There was progression to...

PURPOSE To evaluate the therapeutic outcomes and late toxicities in patients treated by high-dose-rate brachytherapy (HDR-BT) with external beam radiotherapy (EBRT) for localized or locally advanced prostate cancer. MATERIALS AND METHODS From May 2004 to September 2008, 86 men were treated by HDR-BT with EBRT for localized or locally advanced prostate cancer at the National Hospital Organizat...

BACKGROUND The incidence and associated factors of loose seed migration were investigated in cohort 1 of the Japanese Prostate Cancer Outcome Study of Permanent Iodine-125 Seed Implantation (J-POPS). METHODS The study subjects were 2160 patients, consisting of 1641 patients who underwent permanent iodine-125 seed implantation (PI) and 519 patients who underwent PI combined with external beam ...
