In brief

There are two types of external radiation treatments; proton beam and photon beam radiation. What type of therapy participants will receive will depend upon the location of their tumor. Standard treatment would involve receiving either proton or photon radiation delivered by a three dimensional (3-D) conformal radiation technique. 3-D conformal radiation therapy is a technique where the beams of radiation used in the treatment are shaped to match the tumor in order to avoid damaging the healthy surrounding tissue. Standard treatment also may include photon radiation delivered by intensity modulated (IMRT) technique. In this research study we are using an investigational technique to deliver proton radiation therapy called intensity modulated proton radiation treatment (IMPT) which is used to target cancer while sparing healthy tissue. With IMPT (and standard IMRT), radiation intensity can be turned down during the treatment. This control over the intensity of the radiation dose has the potential to provide accuracy and allows us to more safely increase the amount of radiation delivered to the tumor. This accuracy may potentially reduce side effects that patients would normally experience with 3-D proton radiation therapy. Surgery is often an important component of the treatment for these tumors and may be integrated with the IMPT.

Individuals with a history of a different malignancy are ineligible except for the following circumstance. Individuals with a history of other malignancies are eligible if they have been disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 5 years: cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin.Individuals treated for localized, node-negative cancers > 2 years ago with no evidence of cancer are also considered eligible.
HIV-positive individuals on combination antiretroviral therapy
