Introduction: The exact location of the original tumor should be known for a targeted increase in the dose to the tumor bed after breast cancer surgery. Therefore, at our site, we perform CT examinations of patients in the radiation position before breast cancer surgery.
Methods: Preoperative native CT scans were performed in the patients in the planning position for radiotherapy; these data were fused with standard planning CT for boost irradiation.
Purpose: This paper compares individual radiation therapy techniques used for prostate cancer and their benefits in clinical practice.
Methods: We retrospectively analyzed 921 patients with localized prostate tumors treated between 1997 and 2012. We divided the patients into four groups according to the selected treatment technique (conformal radiation therapy [3DCRT], intensity-modulated radiation therapy [IMRT], image-guided radiation therapy [IGRT], and volumetric-modulated arc therapy [VMAT]) and evaluated the incidence of acute and chronic gastrointestinal (GI) and genitourinary (GU) toxicity.
The purpose of this study was to compare the radiation dose to organs at risk for deep-inspiration breath hold (DIBH) and free-breathing (FB) radiotherapy in patients with lef-sided breast cancer undergoing adjuvant radiotherapy after partial mastectomy. Methods: One hundred patients with left-sided breast cancer underwent DIBH and FB planning computed tomography scans, and the 2 techniques were compared. Dose-volume histograms were analyzed for heart, left anterior descending coronary artery (LAD), and left lung.

We evaluated a cohort of patients treated with trastuzumab in the Czech Republic.
Patients And Methods: The present study is a retrospective analysis of patients whose data were recorded in a nationwide non-interventional, post-authorisation database BREAST.
Background: The combination of intensity modulated radiation therapy (IMRT) and image guided radiotherapy (IGRT) plays a significant role in sparing normal tissue during prostate cancer treatment. We report the clinical outcomes of 260 patients treated with high-dose IGRT as well as the toxicity of high-dose IGRT in these patients.
Materials And Methods: From September 2008 to February 2012, 260 men with clinically localized prostate cancer underwent radical radiotherapy.
