ionization radiation caused to incidence of complications in the exposed organs. in prostate radiotherapy, rectum and bladder have been radiated unwantedly and indicated some complications during and after treatment. the purpose of present study is to consider and to compare clinical complications of rectum and bladder in custom block and mlc for 3- d conformal radiotherapy, in order to determi...

background: to analyze the dosimetric and radio biologic advantages between intensity modulated radiotherapy (imrt) and 3 dimensional conformal radiotherapy (3dcrt) and selection of optimal photon energy for imrt treatments. material and methods: 24 patients with localized prostate carcinoma were planned for 3dcrt and imrt techniques. radiation dose of 54 gy with 2 gy/fraction, was planned to p...

The appropriate application of 3-D conformal radiotherapy, intensity modulated radiotherapy or image guided radiotherapy for patients undergoing post-operative radiotherapy for prostate cancer requires a standardisation of the target volume definition and delineation as well as standardisation of the clinical quality assurance procedures. Recommendations for this are presented on behalf of the ...

background : this study determines the efficacy and tolerability of hypofraction- ated three-dimensional conformal radiotherapy in conjunction with daily temozolomide in treatment of previously irradiated recurrent malignant glioma. methods :we enrolled 21 patients diagnosed with recurrent or progressive malignant glioma who previously underwent external beam irradiation. all patients had hypof...

Introduction: The commonly used technique of radiation therapy for vulvar cancer consists of anteroposterior (AP) and posteroanterior (PA) fields. This is the first study that reports the dosimetric comparison between the AP-PA techniques and the new 3D advanced conformal technique (3D-ACT) based on the multiplicity of treatment fields in patients with squamous cell ca...
