This study is being done to test the safety of a single high-dose of radiation therapy before radical prostatectomy (removal of the prostate). The investigators want to find out what effects, good and/or bad, the radiation will have on men undergoing prostatectomy. The investigators are especially interested in men who are at risk for having cancer cells that have spread outside the prostate.

This phase II trial studies how well radical-dose image guided radiation therapy works in treating patients with non-small cell lung cancer that has spread to other places in the body who ...
Patients with primary head and neck squamous cell carcinoma (HNSCC) planned for treatment with radiotherapy with or without chemotherapy in curative setting will be treated with an adaptiv...
The purpose of this study is to find out which way of giving high-dose radiation works best for treatment of cancer that has spread to bone, the spine, soft tissue, or lymph nodes. This st...
This single arm, prospective study will determine the prostate-specific quality of life (QOL) of patients undergoing undergoing a 2 fraction MRI-guided stereotactic ablative body radiation...
Hypofractionated intensity modulated and image guided radiotherapy (HypoIGRT) with fewer high-fraction-size treatments would be beneficial for prostate cancer because it would deliver a la...
To develop a method for scoring online cone-beam CT (CBCT)-to-planning CT image feature alignment to inform prostate image-guided radiotherapy (IGRT) decision-making. The feasibility of incorporating ...
Decreasing the radiation dose in the surgical area is important to lower the risk of wound complications when surgery and radiotherapy are combined for the treatment of spinal metastases. The purpose ...
Stereotactic body radiotherapy (SBRT) emerged as a treatment option in oligometastatic (≤3 metastases) patients experiencing lymph node relapse from treated prostate cancer. No recommendations are a...
Image-guided high-dose-rate interstitial brachytherapy (iBT) with iridium-192 is an effective treatment option for patients with liver malignancies. Little is known about long-term radiation effects o...
Hypofractionated (>5 fraction) stereotactic radiotherapy (HSRT) may allow for ablative biologically equivalent dose to tumors with a lower risk of organ-at-risk (OAR) toxicity in central thoracic tumo...
Radiotherapy where there is improved dose homogeneity within the tumor and reduced dosage to uninvolved structures. The precise shaping of dose distribution is achieved via the use of computer-controlled multileaf collimators.
CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions.
The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
Mice selectively bred for hypersusceptibility to two-stage chemical skin carcinogenesis. They are also hypersusceptible to UV radiation tumorigenesis with single high-dose, but not chronic low-dose, exposures. SENCAR (SENsitive to CARcinogenesis) mice are used in research as an animal model for tumor production.
Prostate cancer (cancer de prostata) Prostate cancer (cancer de prostata) is a form of cancer that develops in the prostate, a gland in the male reproductive system. Most prostate cancers are slow growing; however, there are cases of aggressive prostat...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
