Three-Dimensional Conformal Radiation Therapy Reduces Rectal Damage in Prostate Cancer Treatment
August 2nd 2001ST. LOUIS-Three-dimensional (3D) conformal radiation therapy is being widely used for treatment of prostate cancer and has been successful at reducing rectal toxicities. "Conformal radiotherapy has allowed dose escalation with acceptable or even reduced rates of severe morbidity," Jeff M. Michalski, MD, reported. He added, however, that "we have to start paying attention to the low-grade morbidity. Grade 1 and grade 2 toxicity may predict development of severe late complications." Dr. Michalski is assistant professor of radiology, Mallinckrodt Institute of Radiology, Washington University, St. Louis.

Better Radiation Toxicity Standards Needed in Both Clinical Trials and Practice
August 2nd 2001TAMPA, Florida-Standards for reporting toxicity related to radiotherapy are at least 5 years behind those developed for chemotherapy and need to be improved before the field can advance, according to Andy Trotti, MD. "There is a need for a common late effects grading system and a need for reporting standards," Dr. Trotti said. He is program leader and director of clinical trials, Radiation Oncology, H. Lee Moffitt Cancer Center and Research Institute, Tampa, Florida.
