Introduction: Clinical radiation nephropathy can result in considerable morbidity and/or mortality. Renal tolerance (TD5/5) has been stated to be 20 Gy when irradiation has been delivered to both kidneys in 3-5 weeks. Therefore to minimize renal toxicity in these patients, localization and shielding of the kidneys are essential. This study was carried out to evaluate the role of 99mTc-DTP...

Ovarian granulosa cell tumors (GCTs) are uncommon neoplasms that arise from the sex-cord stromal cells of the ovary. GCTs are characterized by long natural history and their tendency to recur years after the initial diagnosis. They present with symptoms and signs due to estradiol secretion, including vaginal bleeding and precocious puberty. Occasionally, tumor rupture causes abdominal pain and ...

Respiratory gating is used to counter the effects of organ motion during radiotherapy for chest tumors. The effects of variations in patient breathing patterns during a single treatment and from day to day are unknown. We evaluated the feasibility of using patient training tools and their effect on the breathing cycle regularity and reproducibility during respiratory-gated radiotherapy. To moni...

PURPOSE The treatment of moving targets with intensity-modulated radiotherapy may introduce errors in dose delivery. The motion of tumors in the abdomen was studied using quantitative fluoroscopic analysis, and the effect on dose delivery to the target was studied. METHODS AND MATERIALS Fluoroscopy sessions for 7 patients with pancreas or liver tumors and fiducial clips were recorded, convert...

BACKGROUND Radical hysterectomy and radiotherapy have long been mainstays of cervical cancer treatment. Early stage cervical cancer (FIGO stage IB1-IIA) is traditionally treated using radical surgery combined with radiotherapy, while locally advanced cervical cancer is treated using radiotherapy alone or chemoradiotherapy. In this retrospective study, we describe and analyse the presenting clin...

BACKGROUND The aim of the present study is to evaluate the effectiveness of the combined application of high-intensity focused ultrasound (HIFU) and radiotherapy in the treatment of locally advanced pancreatic carcinoma (LAPC). METHODS A total number of sixteen patients with LAPC started treatment beginning with HIFU and radiotherapy 1 week after the HIFU treatment. Evaluation of the effectiv...

Radiation-induced mucositis is a common and serious side effect of radiotherapy. Molecular mechanisms of mucosal injury, however, are still poorly understood and extremely difficult to study in humans. A novel Dark Agouti rat model using fractionated radiotherapy to induce mucositis has been developed to investigate the occurrence of alimentary mucosal injury. Twenty-four Dark Agouti rats were ...
