Dear OncoLink "Ask The Experts,"
Why do I need to have radiation and chemotherapy at the same time?
Richard Whittington, MD, Associate Professor of Radiation Oncology at the University of Pennsylvania School of Medicine, responds:
Chemotherapy blocks many of the repair activities of tumor cells without having the same effect on normal cells. This increases the sensitivity of tumor cells to the effects of radiation. There have been numerous clinical studies that show patients do much better when chemotherapy and radiation therapy are given concurrently.
Jan 20, 2011 - The combination of chemotherapy with intensity-modulated radiation therapy is equally as effective for the treatment of anal cancer after two years as the combination of chemotherapy and conventionally delivered radiation therapy, as well as less toxic, according to a study presented at the American Society of Clinical Oncology's annual Gastrointestinal Cancers Symposium, held from Jan. 20 to 22 in San Francisco.
