WASHINGTON-A second Secretary of Health and Human Services (HHS), Tommy G. Thompson, has refused to allow the reimporting of US-made prescription drugs back into the country. Former HHS Secretary Donna E. Shalala made the same determination last December.
HOUSTON, Texas-Interim data from a trial of relatively high-dose irinotecan (Camptosar) given every 3 weeks show that the regimen can be tolerated and has substantial activity in relapsed aggressive or indolent non-Hodgkin’s lymphomas (NHL). Andreas H. Sarris, MD, PhD, associate internist in the Department of Lymphoma and Myeloma at the University of Texas M. D. Anderson Cancer Center in Houston, Texas, discussed the ongoing study. "Irinotecan weekly schedules have been associated with both early and delayed diarrhea, which is often dose limiting. Recent studies have demonstrated that 300 mg/m² IV every 21 days is active and tolerated in patients with colon cancer," Dr. Sarris said.
RESEARCH TRIANGLE PARK, NC-The National Toxicology Program (NTP) will probe questions about the safety of cellular telephones in a 5-year series of rodent studies. The agency said that the study is in response to the requests from citizens who claim cell phones have caused a variety of health problems. Most studies done to date have failed to show that cell phones cause any ill effects, but many of these studies were funded by the cell-phone industry.

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.
