Tumors2

• In lymphomas I have conducted studies in rare aggressive primary cutaneous tumors such as gamma/delta T cell lymphoma (expanding the description of the epidermotropic variant) as well as more indolent entities such as lymphomatoid papulosis (type D) and CD4-positive small to medium size T cell lymphoproliferative disorders. (mdanderson.org)
• The use of MRI and contrast agents has improved the accuracy of non-invasive diagnosis of these tumors, and especially in the identification of specific molecular subtypes of liver adenoma. (golearnweb.com)

• As part of our mission to eliminate cancer, MD Anderson researchers conduct hundreds of clinical trials to test new treatments for both common and rare cancers. (mdanderson.org)
