MEMPHIS-‘‘Camptothecin activity is schedule dependent and is very S-phase-specific at concentrations we can achieve in vivo," Peter J. Houghton, PhD, said while summarizing the results of preclinical studies with camptohecins. "Protracted administration is optimal, and threshold concentrations are critical," he continued. Dr. Houghton is chairman of the Department of Molecular Pharmacology at St. Jude Children’s Research Hospital in Memphis.

NEW YORK-The cisplatin/irinotecan combination produces responses among patients with gastric and esophageal cancers, David H. Ilson, MD, PhD, reported at the Vanderbilt University Symposium.

WASHINGTON-Several House and Senate members have introduced bipartisan bills that would authorize the Food and Drug Administration (FDA) to regulate tobacco products. The measures are in response to a Supreme Court decision that rejected the FDA’s claim to such authority and held that "Congress has clearly precluded the FDA from asserting jurisdiction to regulate tobacco products."

NEW ORLEANS-A protein-based compound called BL22 produced complete remissions in patients with hairy cell leukemia resistant to standard therapy with purine analogs. Results of the phase I trial were reported at the 92nd Annual Meeting of the American Association for Cancer Research (AACR).

WASHINGTON-President Bush has asked Congress to appropriate a budget of $23.112 billion for the National Institutes of Health in fiscal year 2002, which begins Oct. 1. His request represents a $2.751 billion (13.5%) increase over the current fiscal year. The President also requested a budget of $4.177 billion for the National Cancer Institute, an increase of $439 million (11.7%).

NEW YORK-The need to test new biologically targeted therapies and the presence of vocal patient advocate groups are among the factors galvanizing the National Institutes of Health to seek wider patient participation in clinical trials, Mary McCabe, RN, said during a Cancer Care, Inc. teleconference. She also made clear that patients need to ask many questions before enrolling. Only 1% to 3% of cancer patients take part in clinical trials, said Ms. McCabe, director of the National Cancer Institute’s Office of Education and Special Initiatives. "We would like to see that change," she said.

LITTLE ROCK, Arkansas-Thalidomide appears to enhance the response rate produced by irinotecan (Camptosar) in metastatic colorectal cancer, while decreasing the drug’s gastrointestinal toxicities, reported Rangaswamy Govindarajan, MD. In addition, thalidomide is well tolerated at 400 mg/d, inhibits tumor necrosis factor-alpha, has antiangiogenic properties, and costimulates CD8+ T-cells, Dr. Govindarajan noted. He is assistant professor of medicine in the Division of Hematology/Oncology at the University of Arkansas for Medical Sciences, Little Rock, Arkansas.

NASHVILLE, Tennessee-"Camptothecins have radiosensitizing as well as cytotoxic effects, and combining a camptothecin such as irinotecan with radiation on the right schedule might produce a powerful antitumor regimen," according to Allan Chen, MD, PhD. Dr. Chen is assistant professor of radiation oncology at Vanderbilt University Medical Center in Nashville, Tennessee.

DURHAM, North Carolina- Topoisomerase I inhibitors have shown promising activity in difficult-to-treat tumors of the central nervous system (CNS), according to Henry S. Friedman, MD. In studies of camptothecins, both irinotecan (Camptosar) and topotecan (Hycamtin) showed "prodigious activity" in slowing tumor growth and causing tumor regression in subcutaneous xenografts of human gliomas, Dr. Friedman told those attending the Vanderbilt University Symposium. Dr. Friedman is Jones B. Powell, Jr., Professor of Neuro-Oncology at Duke University Medical Center in Durham, North Carolina.

PEAPACK, New Jersey-Potential directions for irinotecan (Camptosar) clinical research in the future and for the application of novel therapeutics were presented by Langdon Miller, MD, of Pharmacia Oncology Development in Peapack, New Jersey.

The article by Drs. Levine, Seneviratne, and Tulpule is an excellent review of the available literature on the incidence and treatment of lymphoma related to the acquired immunodeficiency syndrome (AIDS).

Advances in antiretroviral therapy have dramatically improved human immunodeficiency virus (HIV)-associated morbidity and mortality. The use of highly active antiretroviral therapy (HAART) has led to a decrease in the incidence of opportunistic diseases, including some malignancies. Moreover, increased use of effective antiretroviral therapy may alter the incidence, presentation, prognosis, and therapeutic recommendations for patients with acquired immunodeficiency syndrome (AIDS)-related non-Hodgkin’s lymphoma.

Over the past 3 decades, hematopoietic stem cell transplantation has become a lifesaving art that is applied to a variety of malignant and nonmalignant disorders.[1] In the 1970s, several groups demonstrated that advanced leukemia and aplastic anemia patients were cured using sibling-matched allogeneic bone marrow transplantation. By the 1980s, many published reports confirmed that relapsed and refractory lymphoma patients could attain long-term disease-free survival as a result of utilizing autologous bone marrow transplantation.

The demographics of the US population continue to change dramatically, as the absolute number and proportion of older people relative to the remainder of the population increases. Last year, the number of persons older than 65 years was estimated to be 35 million, representing almost 13% of the overall population; by 2030, the older population is expected to double. Along with the general aging of the population, the percentage of persons older than 85 years is also growing rapidly, as is the ethnic and racial diversity within the older population.

Over time, the spectrum of the acquired immune deficiency syndrome (AIDS) epidemic has changed, especially with the advent of highly active antiretroviral therapy (HAART). The goal of this article is to delineate changes

BETHESDA, Md-Revised guidelines for treating HIV-infected adults provide new recommendations for when physicians should initiate anti-HIV therapy. "The new treatment guidelines provide patients and their doctors with evidence-based recommendations for initiating antiretroviral therapy that take into account both the benefits and potential risks of currently available treatment regimens," said Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases (NIAID).
