Hepatocellular Carcinoma (HCC) is still a leading health problem worldwide, due to its correlation with HBV and HCV infection and its management which is strongly dependent on patient’s condition and tumor extension. Surgery, with liver resection or liver transplantation offer a good survival rate as a primary management of such cancer. But since liver resection must consider some aspect of liv...

Patients who have undergone solid organ transplants are known to have an increased risk of neoplasia compared with the general population. We report our experience using mediastinal irradiation with helical tomotherapy versus three-dimensional conformal radiation therapy to treat a patient with lung carcinoma 15 years after heart transplantation. Our dosimetric evaluation showed no particular d...

Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...

In the recent days, prostate cancer can be managed by several options such as surgery, chemotherapy, radiotherapy, etc. Radiotherapy is considered as one of the popular options to treat prostate cancer due to excellent survival rate and fewer side effects. The field of radiotherapy is evolving since...

At the very start of their clinical training, radiation oncologists tend to embrace technology. The specialty draws a preponderance of technophiles to it, and those few who are not at first passionate about technology quickly become so. This has been especially true over the past 2 decades with the introduction of innovative therapies such as three-dimensional conformal radiation therapy (3DCRT...

background: identify the optimal technique of radiotherapy for patients with high grade glioma. our initial year of experience with rapidarc radiation therapy. materials and methods: planning ct scans of 50 patients with grade iv glioma were reviewed and three plan sets by 3d conformal radiotherapy (3dcrt), intensity modulated radiotherapy (imrt) and rapid arc (ra) were generated and the plans ...
