Prostate cancer is the one of the most commonly diagnosed cancer among men throughout the world. 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...
Patients with left-sided breast cancer are at risk of cardiac toxicity because of cardiac irradiation during radiotherapy with the conventional 3-dimensional conformal radiotherapy technique. In addition, many patients may receive chemotherapy prior to radiation, which may damage the myocardium and may increase the potential for late cardiac complications. New radiotherapy techniques such as in...
Conventional radiotherapy for cervical cancer relies on clinical examination, 3-dimensional conformal radiotherapy (3D-CRT), and 2-dimensional intracavitary brachytherapy. Excellent local control and survival have been obtained for small early stage cervical cancer with definitive radiotherapy. For bulky and locally advanced disease, the addition of chemotherapy has improved the prognosis but t...
PURPOSE To study the risks of early and late radiogenic lung damage in breast cancer patients after conformal radiotherapy. METHODS AND MATERIALS Radiogenic lung sequelae were assessed prospectively in 119 patients by means of clinical signs, radiologic abnormalities, and the mean density change (MDC) of the irradiated lung on CT. RESULTS Significant positive associations were detected betw...
Introduction: Modern radiotherapy (RT) techniques allow a highly precise deposition of the radiation dose in tumor. So, high conformal tumor doses can be reached while sparing critical organs at risk. Materials and Methods: This study was conducted in three phases. In the first phase; Fourteen patients with primary or recurrent prostate cancer receive Gallium-...
Modern radiotherapy facilities like 3-Dimensional conformal radio therapy (3DCRT), Intensity Modulated Radiotherapy (IMRT), were recently suggested in Co-60 machine with Multi-leaf Collimator (MLC). In this study, two reference chambers NE-2571#1205 and NE2581#537 used for absolute dose measurement Equinox accelerator. A comparison of by different IAEA protocols TRS-277 TRS-398 has been studied...
This retrospective study aimed to observe the cura-tive effect and adverse reactions of three-dimensional conformal radiotherapy combined with topotecan chemotherapy in patients with platinum-resistant recurrent epithelial ovarian carcinoma. The chemoradiotherapy group (N = 22) received 15 mv X-rays with 1.8 to 2.0 Gy/f/d radiation, 5 times per week. The total dose was 45 to 65 Gy; the median d...
Assessment of Olfactory Threshold in Patients Undergoing Radiotherapy for Head and Neck Malignancies
Introduction: Radiotherapy is a common treatment modality for patients with head and neck malignancies. As the nose lies within the field of radiotherapy of the head and neck, the olfactory fibers and olfactory receptors may be affected by radiation. The aim of this study was to evaluate changes in olfactory threshold in patients with head and neck malignancies who have received radiation to th...
ID: 13564 Title: A novel conformal arc technique for postoperative whole pelvic radiotherapy of endometrial cancer Introduction: Conventional whole pelvic radiotherapy (WPRT) with three-dimensional conformal radiotherapy (3D-CRT) exposes most of the contents of the true pelvis to the prescribed dose. Intensity-modulated radiation therapy (IMRT) provides more conformal dose distribution and bett...
