The growth of many breast cancers is regulated by estrogens, and these cancers can be treated effectively with endocrine therapies (ET). Identifying patients who will benefit from ET, however, continues to be challenging. Measurement of estrogen receptor (ER) levels in tumor biopsy samples using immunohistochemistry provides accurate negative prediction (no ER implies no ET response), but poor positive prediction. We have developed a fluorine-18 labeled estrogen, 16alpha-F-18fluoro-17beta-estradiol (FES) for in vivo imaging of ER in breast cancer by positron emission tomography (PET). Clinical PET imaging studies with FES provides a higher positive predictive value for benefit from ET than does IHC. In addition, an endocrine challenge test that measures the change in tumor metabolism, assessed by PET with 2-F-18fluoro-2-deoxyglucose (FDG) 1 week after tamoxifen or after 1 day of estradiol therapy, provides a highly accurate prediction of the ultimate benefit of ET in treatment. Both FES-PET and serial FDG-PET are promising approaches whereby it should be possible to tailor ET to individual breast cancer patients.
Cancer Community At Illinois Symposium 2012 April 5-6, 2012: Connecting patient care, research, and scientific advancement Symposium Premise This on-campus research symposium aims to bring together members of campus and the surrounding community to foster interdisciplinary discussions on cancer research and its affects on patient care. In order to increase understanding and awareness, we will discuss in an open forum with research talks, poster presentations, and panel discussions. We invite community members, clinicians, and researchers from UIUC and other Midwest regional institutions from departments ranging from the social sciences to basic sciences to engineering and medicine. The symposium features invited talks from nationally-recognized cancer researchers, oral presentations from UIUC faculty and students, and poster sessions. We encourage student researchers from UIUC and from other regional schools to apply (travel awards are available). About CC@I Symposium The Cancer Community at Illinois (CC@I) Symposium is organized by a group of students on the University of Illinois campus to bridge the areas of social science, basic sciences to engineering and medicine as they relate to cancer. The symposium mission is to: 1) Facilitate interdisciplinary collaboration and understanding that transcends established departmental affiliation; 2) Foster an increased understanding of the social and environmental factors affecting patients; and 3) Develop unique vantage points afforded by interactive dialogue between and among the various cancer research disciplines. In order to accomplish this, the symposium will engage the local patient community through use of the nascent social and support efforts of the Mills Breast Cancer Institute, Carle Hospital, and regional clinical collaborators.
