NEW ORLEANS-"Knots" in DNA may become potential targets of cancer therapeutics, according to an investigator who described these new structures at the 92nd Annual Meeting of the American Association for Cancer Research (AACR abstract 1123).
ST. 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.
ST. LOUIS-Soon to be launched is a trial to determine if amifostine (Ethyol) with concurrent infusion of 5-fluorouracil will permit delivery of higher boost doses of radiation in unresectable or locally recurrent rectal cancer.
ST. CROIX-The discovery that radioprotectants can be used in some settings to protect normal tissues from radiation damage promises to greatly extend the usefulness of regimens that combine systemic chemotherapy and radiation therapy. The First Investigators’ Congress on Radioprotection, held June 7 to 10, 2001 served as a forum to review current progress and discuss new developments in strategies for radioprotection.
ROCHESTER, New York-Interleukin-6 (IL-6) and interleukin 1-alpha (IL-1a) are potentially useful predictors of risk for development of postradiation pneumonitis, according to Yuhchyau Chen, MD, PhD. "Delayed peak of pneumonitis occurs at 6 to 9 months, and we expect that there will be a role for radioprotective agents in this setting," she said. Dr. Chen is assistant professor of radiation oncology, University of Rochester Medical Center, New York.
DURHAM, North Carolina-"We have a positive randomized trial of amifostine (Ethyol), and it represents the first time that a treatment has been approved by the Food and Drug Administration (FDA) that interacts with radiation therapy," David M. Brizel, MD, said.
DETROIT-Intrarectal topical application of amifostine (Ethyol), given as a "mini-enema," is extremely tolerable, produces no systemic toxicity, and may be an alternative to systemic administration for preventing rectal damage in patients undergoing radiotherapy for prostate cancer. Results of a phase I study were reported by Edgar Ben-Josef, MD. He is associate professor in the Department of Radiation Oncology at Wayne State University’s Karmanos Cancer Institute in Detroit.
PHILADELPHIA-In designing trials of potential toxicity modifiers, consideration must be given to endpoint selection and correlation of endpoints, as well as sample size and analysis methods.
