Filter by:The goal of this interventional pilot trial is to confirm that Maastro endoluminal HDR ( High Dose Radiation) contact brachytherapy boosting is feasible and may increase the chance of functional organ sparing of the rectum in patients with rectal cancer. Participants will be treated with chemoradiotherapy and an endoluminal boost with the Maastro applicator.

The aim is to quantify the efficiency of the Safetac product Mepitel® Film on the prevention of radiodermatitis for cancer patients treated with external beam radiation therapy near the inguinal fold(s). Previous studies have looked into the differences in skin reactions for Mepitel® Film versus hydro-active colloid gel in breast cancer [1, 2] and head and neck cancer [3]. In breast cancer, the prevalence of radiation induced dermatitis has strongly decreased due to of modern radiotherapy techniques and fractionation. In the groin, however, this is not the case, and radiation dermatitis remains an important problem. To the best of our knowledge, no previous study has looked into the efficiency of a prophylactic Mepitel® Film protocol in the inguinal fold. The goal of this study is to evaluate whether the Mepitel® Film offers a lower degree of radiation-induced dermatitis compared to hydro-active colloid gel and thereby challenging the gold standard.

This study was designed to evaluate the acute toxicity and quality of life of hypofractionated radiation versus conventional when regional node irradiation is indicated after breast-conserving surgery or mastectomy.
Radiation therapy (RT) of the breast is a critical component of modern breast cancer treatment. RT treatments have led to improved local control and overall survival of breast cancer patients. However, the incidence of radiation induced harmful effects is increasing in these patients. This is because in delivering RT, it is difficult to completely avoid surrounding non-cancerous normal tissue, including the heart. The main concern here is that radiation induced effects on the heart may lead to an increased risk of cardiovascular disease later in a patient's life, potentially many years after radiation. Despite methods that can detect alterations in blood flow one to two years following radiotherapy, knowledge of early radiation effects to the heart is still limited. A previous animal experiment performed by our group involved delivering a radiation dose to the heart in a manner similar to the way a heart would be exposed, during radiotherapy for a cancer involving the left breast. Taking several images over the months following radiation with a new imaging technique, hybrid PET/MRI, has suggested an increase in inflammation can be detected as early as one-week following irradiation and may be the triggering event for cardiac disease seen in women 10-15 years after radiotherapy. The investigators propose a pilot study where 15 left-sided breast cancer patients undergoing radiotherapy will be imaged before, as well as one week and one-year post radiotherapy with our hybrid PET/MRI scanner. Areas of inflammation, changes in blood flow, and scar formation within the heart, will be measured by looking at the difference between images that are taken after radiation treatment to the images taken before treatment. The expectation is that any areas of the heart that show detectable differences in the images will be directly related to how much radiation was deposited in those areas. The information gained from this pilot study which will correlate the amount of radiation administered to the degree and extent of injury will help aid in the design of new treatment strategies, that can hopefully decrease or eliminate inadvertent heart damage, thereby, improving the quality of life for breast cancer patients.
