introduction radiotherapy with small fields is used widely in newly developed techniques. additionally, dose calculation accuracy of treatment planning systems in small fields plays a crucial role in treatment outcome. in the present study, dose calculation accuracy of two commercial treatment planning systems was evaluated against monte carlo method. materials and methods siemens once or linea...

PURPOSE A retrospective analysis to determine the efficacy of postoperative radiation therapy, in patients of carcinoma of the buccal mucosa and lower alveolus with pathologically verified positive surgical margins (PSM). MATERIALS AND METHODS Ninety-four patients were analysed, who underwent surgery plus postoperative radiation therapy. Twenty-nine patients (31%) had PSM. Other pathological ...

BACKGROUND Peri-operative radiation of retroperitoneal sarcomas (RPS) is an important component of multidisciplinary treatment. All retrospective series thus far included patients treated with older radiation therapy (RT) techniques including 2D and 3DRT. Intensity modulated radiation therapy (IMRT) allows for selective dose escalation while sparing adjacent organs. We therefore report the firs...

introduction today, there is a growing interest in the use of hadrontherapy as an advanced radiotherapy technique. hadrontherapy is considered a promising tool for cancer treatment, given its high radiobiological effectiveness and high accuracy of dose deposition due to the physical properties of hadrons. however, new radiation modalities of dose delivery and on-line beam monitoring play crucia...

UNLABELLED Heterotopic ossification is a well-known complication after fixation of an acetabular fracture. Indomethacin and radiation therapy are used as prophylaxis to prevent heterotopic ossification. It is unclear, however, whether either is superior, although this may relate to lack of power in individual studies. To compare the effectiveness of indomethacin with the effectiveness of radiat...

Introduction:   Radiotherapy with or without surgery plays an important role in the treatment of patients with esophageal cancer. In the treatment planning of esophageal cancer, usually normal lung volume was observed in the treatment fields and probably received high radiation dose. The incidence of radiation pneumonitis (RP) after radiotherapy (RT) for sensitive organ of lu...
