Introduction: External radiotherapy is the most common method of radiotherapy which the most important problem associated with is that there is no difference between healthy and tumor tissues in dose absorption. One way to differentiate the dose sensitivity is to use metal-based nanoparticles. Bismuth oxide nanoparticles are good candidates for cancer radiotherapy. In this study, we investigate...
Background: Numerous unique characteristics of the nanosized gold, including high atomic number, low toxicity, and high biocompatibility make it one of the most appropriate nanostructures to boost radiotherapy efficacy. Many in-vivo and in-vitro investigations have indicated that gold nanoparticles (AuNPs) can significantly increase tumor injuries in low kilovoltage radiotherapy. While deep-lyi...
BACKGROUND Recent randomised studies reported that single fraction radiotherapy was as effective as multifraction radiotherapy in relieving pain due to bone metastasis. However, there are concerns about the higher re-treatment rates and the efficacy of preventing future complications such as pathological fracture and spinal cord compression by single fraction radiotherapy. OBJECTIVES To under...
Objective. To compare adjuvant radiotherapy and salvage radiotherapy after radical resection for treatment of esophageal squamous cell carcinoma (ESCC). Methods. Data from 155 patients with locally advanced ESCC who underwent radical resection and received postoperative radiotherapy from 2005 to 2011 were reviewed. Seventy-nine patients received adjuvant radiotherapy and 76 received salvage rad...
PURPOSE Genetic radiotherapy, the combination of gene therapy and radiation therapy, for cancer treatment is evolving from laboratory studies to clinical trials. Genetic radiotherapy involves the viral infection of cells that change the sensitivity of transduced cells to radiation. Because there is no patient outcome data for genetic radiotherapy, prospective models are needed to determine the ...
Background: Bone is the most common site for metastases in cancer and may complicate a wide range of malignancies. Radiotherapy successful efficient method pain palliation it can prevent morbidity bone metastases. Pain flare event, occurring almost 40% patients that receive palliative radiotherapy. Dexamethasone has shown possibility prevention such flare. Objective: This study aimed to investi...
On March 15, 2005, the U.S. Food and Drug Administration approved temozolomide (Temodar capsules, Schering-Plough Research Institute) for the treatment of adult patients with newly diagnosed glioblastoma multiforme concomitantly with radiotherapy and then as maintenance treatment. Five hundred seventy-three glioblastoma multiforme patients were randomized to receive either temozolomide + radiot...
BACKGROUND Outcome data in young women with ductal carcinoma in situ (DCIS) are rare. The benefits of boost radiotherapy in this group are also unknown. We aimed to assess the effect of boost radiotherapy in young patients with DCIS. METHODS We included 373 women from 18 institutions who met the following inclusion criteria: having tumour status Tis and nodal status (N)0, age 45 years or youn...
Imaging has been integral to radiotherapy for decades. However, it has been within the last 20 years that phrases such as ‘image guidance’ have become part of mainstream radiotherapy vocabulary, and the use of all available imaging modalities within radiotherapy more common. So what is meant by ‘image guidance in radiotherapy’? This was one of the questions that the National Radiotherapy Implem...
