Cancer Prevention Research Hampered by Lack of Biomarkers
February 1st 2002WASHINGTON-"The search for cancer prevention agents is hampered by the fact that only one biomarker-the prostate-specific antigen (PSA)-now offers a simple, noninvasive measure of the cancer process in the body," Robert W. Day, MD, PhD, said at a meeting of the Cancer Prevention Working Group, sponsored by the Cancer Research Foundation of America (CRFA). "The need for cancer biomarkers is critical, not only for their diagnostic benefits but also to provide endpoints for judging the effectiveness of any proposed chemopreventive agents."

MCP Active in Advanced Indolent NHL
February 1st 2002ERFURT, Germany-Interim data from a randomized phase III study show that MCP (mitoxantrone [Novantrone], chlorambucil [Leukeran], prednisolone) with or without rituximab (Rituxan) is active in advanced indolent lymphomas. Michael Herold, MD, reporting for the Ostdeutsche Studiengruppe Haematologie/Oncologie (OSHO), said, "The response rate of 81% is within the range of that seen with standard therapies. The complete response (CR) rate of 40% was highly encouraging, particularly given the multi-institutional setting of this study. To date, no significant change in response has been seen with the addition of rituximab to MCP, but further follow-up is needed to determine if the addition of rituximab will improve the duration of response."
NCI Releases Report on Nation’s Progress Against Cancer
February 1st 2002BETHESDA, Maryland-The National Cancer Institute’s Cancer Progress Report 2001-a living document that the Institute will update once or twice a year online and every few years in printed form-renders a mixed judgment about the nation’s success in reducing the burden of cancer.

February 1st 2002HOUSTON-A modified "hyper-CVAD" (cyclophosphamide [Cytoxan, Neosar], vincristine, doxorubicin [Adriamycin], dexamethasone) regimen, which included the addition of rituximab (Rituxan) for CD20-positive patients and the use of laminar airflow rooms for patients who were elderly or had poor performance status, reduced induction mortality in older patients with acute lymphoblastic leukemia (ALL). Overall mortality was not changed, because a number of patients died of other causes while in complete remission (CR).

Stress Accelerates AIDS Progression, Undermines the Effect of Therapy
February 1st 2002New research from the AIDS Institute at the University of California, Los Angeles (UCLA), reveals that stress enables the human immunodeficiency virus (HIV) to spread more quickly in infected persons and prevents antiretroviral drugs from restoring immune system function. The study, which was reported in the Proceedings of the National Academy of Sciences (98:12695-12700, 2001), is the first to pinpoint the molecular mechanisms linking stress and HIV infection. "Popular science has widely suspected that stress weakens the immune system," said Steve Cole, MD, lead author and UCLA assistant professor of hematology-oncology. "Now we’ve uncovered two reasons why."

Rituximab/Fludarabine Combination Feasible in CLL
February 1st 2002COLOGNE, Germany-Combining rituximab (Rituxan) with fludarabine (Fludara) is a feasible, effective strategy in treating chronic lymphocytic leukemia (CLL), as it produces a 90% response rate and does not increase infection risk beyond that seen with fludarabine alone, Holger Schulz, MD, reported in a poster presentation at the 43rd Annual Meeting of the American Society of Hematology. Dr. Schulz is in the Department of Hematology/Oncology at the University of Cologne, Germany.
Adding Radiotherapy to CHOP Improves Results for Early- or Limited-Stage NHL
February 1st 2002ORLANDO, Florida-Updated data from two separate studies ratify earlier results showing that following CHOP (cyclophosphamide [Cytoxan, Neosar], doxorubicin HCl, vincristine [Oncovin], prednisone) with radiation improves results for patients with early- or limited-stage non-Hodgkin’s lymphoma (NHL).
Radioimmunotherapy Improves Response in Chemotherapy-Refractory NHL
February 1st 2002A new study published in the Journal of Clinical Oncology (19:3918-3928, 2001) reported that radioimmunotherapy with tositumomab/iodine-131 tositumomab (Bexxar), produced more durable complete or partial clinical responses in patients with low-grade and transformed low-grade non-Hodgkin’s lymphoma (NHL) than did their last round of chemotherapy. All patients in the study had chemotherapy-refractory NHL. Typically, response rates and durations of response in refractory patients decline with each successive therapy, but in this study, the tositumomab/iodine-131 tositumomab combination was shown to reverse the expected outcome.
‘Cancer Prevention Must Move From Thought to Reality’
February 1st 2002WASHINGTON-"Cancer prevention now requires that we move from thought to reality," said Carolyn Aldigé, founder and president of the Cancer Research Foundation of America (CRFA). "This mean a new paradigm of the health care system, rather than just taking care of sick people. Treatment of advanced disease has less impact than prevention."
Rituximab ‘Surprisingly Active’ as First-Line or Maintenance Therapy for SLL and CLL

February 1st 2002HOMBURG, Germany-After conducting trials comparing CHOP (cyclophosphamide [Cytoxan, Neosar], doxorubicin HCl, vincristine [Oncovin], prednisone) with and without etoposide and varying time intervals, the German High-Grade Non-Hodgkin’s Lymphoma Study Group concluded that CHOP plus etoposide is the new standard regimen for younger patients with low-risk non-Hodgkin’s lymphoma (NHL), and CHOP at 2-week intervals is the new standard regimen for aggressive NHL in older patients.
