This study evaluates three-dimensional conformal radiotherapy (3D CRT), volumetric-modulated arc therapy (VMAT), and dynamic conformal arc therapy (DCAT) planning techniques using dosimetric indices from Radiation Therapy Oncology Group (RTOG) protocols 0236, 0813, and 0915 for the treatment of early-stage non-small cell lung cancer (NSCLC) using stereotactic body radiotherapy (SBRT). Twenty-fi...

BACKGROUND Hypofractionated three-dimensional conformal radiation therapy (3D-CRT) is a treatment option for patients with early-stage non-small cell lung cancer (NSCLC) who are medically unable to tolerate surgery and who are not amenable to treatment with stereotactic body radiotherapy. This study assessed the efficacy and safety of 3D-CRT as a monotherapy in patients with localized stage T2 ...

the present research is a field study in order to investigate scale and ways of doing breast self examination (bse). 270 nurses employed by the medical sciences university’s hospitals related to the ministry of health, and medical education in city of tehran are selected and involved in research on the basis of simple random sampling. the data collection tool was a protrayed questionnaire which...

Background: Tangential irradiation of intact breast is one of the most common procedures performed in any radiotherapy center. This method is performed by using 2D and 3D treatment planning. The aim of this study was to compare 2D with 3D plans in breast conserving radiotherapy. Homogeneity of isodose, and lung received dose were compared. Materials and Methods: Twenty patients with br...

OBJECTIVES Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right-sided cancer. METHODS To minimize potential confounding factor...

BACKGROUND The aim of this study was to evaluate the survival outcomes and toxicity of postoperative chemoradiotherapy with capecitabine and concurrent intensity-modulated radiotherapy (IMRT) or three-dimensional conformal radiotherapy (3D-CRT) in patients with stage II and III rectal cancer. PATIENTS We recruited 184 patients with pathologically proven, stage II or III rectal cancer. Followi...

AIMS To evaluate the dosimetric profile among three-dimensional conformal radiotherapy (3D-CRT) and stereotactic radiotherapy (SRT) for the treatment of intracranial tumors. MATERIALS AND METHODS Seventeen patients with intra cranial tumors of benign nature or low malignant potential were enrolled and planned for SRT as well as 3D-CRT. Dosimetric comparison between these two plans was done co...

PURPOSE The purpose of this study was to compare intensity-modulated radiation therapy (IMRT) and three-dimensional conventional radiotherapy (3D-CRT) with regard to patient-rated xerostomia, Radiation Therapy Oncology Group (RTOG) acute and late xerostomia and health-related quality of life (HRQoL) among patients with head and neck squamous cell carcinoma (HNSCC). METHODS AND MATERIALS Inclu...

The present study compared the dosimetry of intensity-modulated radiation therapy (IMRT) and three-dimensional conformal radiation therapy (3D-CRT) techniques in patients treated for high-grade glioma. A total of 20 patients underwent computed tomography treatment planning in conjunction with magnetic resonance imaging fusion. Prescription dose and normal-tissue constraints were identical for t...
