PURPOSE We aimed to evaluate the feasibility of the heart block with electron compensation (HBE) technique, based on three-dimensional conformal radiotherapy (3D-CRT) in left-sided breast cancer patients with underlying cardiac or pulmonary disease. METHODS Twenty patients with left-sided breast cancer who were treated with whole breast radiotherapy (WBRT) were included in this study. Intensi...

Purpose Primary cutaneous anaplastic large cell lymphoma (pcALCL) is conventionally treated with radiation therapy (RT) doses ≥30 GGy, but effectiveness of lower doses is unclear. We compared responses after a range of RT doses for pcALCL. Methods and materials From 1999 through 2015, 45 lesions in 21 patients met clinicopathologic pcALCL diagnostic criteria and were treated with RT (<20 Gy, ...

PURPOSE To evaluate the feasibility of using helical tomotherapy for locally advanced left-sided breast cancer. METHODS AND MATERIALS Treatment plans were generated for 10 left-sided breast cancer patients with positive lymph nodes comparing a multiport breast (three-dimensional) technique with the tomotherapy treatment planning system. The planning target volumes, including the chest wall/br...

BACKGROUND We aimed to assess outcomes of patients with anal cancer who underwent intensity-modulated radiotherapy (IMRT) and received less than 1.80 Gy/day. METHODS We retrospectively reviewed our experience using a low fractional dose (< 1.80 Gy) of IMRT to elective nodal areas for patients receiving chemoradiotherapy for anal cancer. Three-year freedom from any disease relapse and overall ...

Purpose: Investigation of the influence of radiation dose to salivary glands on xerostomia in patients with head and neck cancers. Methods: From October 2002 to December 2011, 548 patients with head and neck carcinomas were treated in our department using intensity modulated radiotherapy (IMRT). 325 patients were eligible for analysis more than 1 year after irradiation. Xerostomia was evaluated...

Wheat is one of the most important sources food worldwide. A selection index helps in making decisions and permits exploitation information on correlated traits to improve yields. Two cycles pedigree based desired-genetic-gain were imposed identify best isolate promising lines. The base population was composed 120 families bread wheat F6 generation. Eight combinations constructed from six trait...

Radiotherapy is a mainstay of treatment of locally advanced Non-Small Cell Lung Cancer (NSCLC). Despite that there is a relative paucity of prospective trials directed on the radiotherapy use in this indication in comparison with prospective studies related to the use of chemotherapy. In this context, a recently published randomized study by [1]. is certainly to be welcomed. This randomized pha...

INTRODUCTION The purpose of this study was to evaluate the dosimetric and radiobiological impact of intensity modulated proton therapy (IMPT) and RapidArc planning for high-risk prostate cancer with seminal vesicles. METHODS Ten high-risk prostate cancer cases were included in this retrospective study. For each case, IMPT plans were generated using multiple field optimisation (MFO) technique ...

The purpose of the present study was to test the behavior of two different generations of cochlear implant systems subjected to a clinical radiotherapy scheme and to determine the maximal acceptable cumulative radiation levels at which the devices show out-of-specification behaviors. Using stereotactic irradiation (Cyberknife, 6 MV photon beam), three Digisonic SP and three Neuro devices were s...

Re-irradiation is challenging for esophageal cancer patients with local-regional recurrence after initial radiotherapy. The purpose of this study is to establish a recurrent esophageal tumor model and investigate radiosensitizing effects of sodium glycididazole (CMNa). Tumor models were established by pre-irradiation (0 Gy, 10 Gy or 20 Gy) to the right hind leg of the nude mice 24 hours before ...
