NCI Seeks to Expand Participation in Cancer Clinical Trials
May 1st 2001NEW 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.
Thalidomide Appears to Enhance Activity of Irinotecan
May 1st 2001LITTLE 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.

Incidence and Management of AIDS-Related Lymphoma
May 1st 2001Advances 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.

Transplant Registries: Guiding Clinical Decisions and Improving Outcomes
May 1st 2001Over 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.
