CAD Accurate in Digital Images
March 1st 2002CHICAGO-Computer-aided detection (CAD) has been shown to improve the identification of breast malignancies on film-based mammography in studies involving large databases of films, said Kathryn O’Shaughnessy, PhD, director of clinical and regulatory affairs, R2 Technology, Inc., Los Altos, California. Now, the method has been shown to be equally accurate in the analysis of full-field digital mammography images, she said at the 87th Scientific Assembly and Annual Meeting of the Radiological Society of North America (abstract 995).
Campath-1H Safe and Effective in Refractory B-CLL
March 1st 2002ORLANDO-About one third of "bad prognosis" refractory B-cell chronic lymphocytic leukemia (B-CLL) patients are salvageable with alemtuzumab (Campath-1H), according to a compassionate use study presented at the 43rd Annual Meeting of the American Society of Hematology (abstract 1538).
Rituximab in the Treatment of Acquired Factor VIII Inhibitors
March 1st 2002Autoantibodies against factor VIII are rare but may cause life-threatening bleeding. Up to 30% of inhibitors may resolve spontaneously, but immunosuppressive drugs with possible serious adverse effects and costly factor replacement are usually required. Rituximab (Rituxan), a humanized monoclonal antibody against CD20-positive B cells, has been reported to be beneficial in certain antibody-mediated autoimmune diseases. We describe here four consecutively treated patients whose acquired factor VIII inhibitors responded rapidly to immunosuppressive regimens that included rituximab administered at 375 mg/m² weekly for 2 to 4 weeks.
FDA Approves Orfadin for Hereditary Tyrosinemia Type 1
March 1st 2002ROCKVILLE, Maryland-The US Food and Drug Administration (FDA) has approved the orphan drug Orfadin (nitisinone capsules, Swedish Orphan International) for treating hereditary tyrosinemia type 1 (HT-1), a rare pediatric disease that causes progressive liver failure and liver cancer. In announcing its approval decision, the agency warned that only physicians experienced in treating the disease should prescribe Orfadin. Rare Diseases Therapeutics, Inc., of Nashville, Tennessee, is the drug’s US distributor.

CAD Equivalent to Double-Read Mammogram Screening
March 1st 2002CHICAGO-Two studies presented at the 87th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) indicate that computer-aided detection (CAD) of lesions on conventional mammography studies is comparable to double-read mammograms, and it produces fewer false-negative results.
Language Problems May Contribute to Misconceptions About Trials
March 1st 2002BOSTON-Misconceptions about cancer clinical trials are common among trial participants, according to a survey of 205 patients and 61 providers conducted at the Dana-Farber Cancer Institute, Brigham and Women’s Hospital, and Massachusetts General Hospital.
Treatment of Acquired Factor VIII Deficiency With Rituximab
March 1st 2002At the 2000 American Society of Hematology meeting, we reported the successful treatment of a patient with acquired hemophilia using rituximab (Rituxan). This patient has required no therapy over the past year and has suffered no further hemorrhages. A June 2001 factor VIII level was 35%, and a factor VIII inhibitor level could not be analyzed due to the high level of factor VIII. Since then, three more patients with acquired factor VIII deficiency have received rituximab therapy at the University of Iowa, and are discussed below.
Phase II Study of Rituximab in the Treatment of Cladribine-Failed Patients With Hairy Cell Leukemia
March 1st 2002Hairy cell leukemia (HCL) is an indolent B-cell neoplasm that strongly expresses CD20. Despite initial very high response rates with cladribine (Leustatin), many patients ultimately relapse.
Anemia Decreases Survival in Women With HIV Infection
March 1st 2002ORLANDO-A multicenter, prospective study has shown that anemia is an independent risk factor predicting decreased survival in HIV-infected women and that highly active antiretroviral therapy (HAART) helps resolve anemia in this population group.
Dr. Klausner Co-Chairs Committee Preparing NAS Terrorism Report
March 1st 2002WASHINGTON-A National Academy of Sciences (NAS) committee expects to issue a report in June on terrorism that will provide the federal government with a road map for the use of science and technology in all aspects of counterterrorism, Richard D. Klausner, MD, former National Cancer Institute (NCI) director, told ONI.
Fewer Americans Smoking Cigars
March 1st 2002ROCKVILLE, Maryland-The number of people who began smoking cigars dropped 22% in 1999, according to a new analysis of data from the 2000 National Household Survey on Drug Abuse (NHSDA). The decline came after a dramatic 208% rise from 1990 to 1998, when nearly 5 million Americans smoked their first cigar.
Phase II Study of Rituximab Plus Fludarabine in Patients With Low-Grade Lymphoma: Final Report
March 1st 2002Both rituximab (Rituxan) and fludarabine (Fludara) have individual antitumor activity against low-grade lymphoma (LGL). The combination of rituximab plus fludarabine has been shown to have synergistic activity against resistant lymphoma cell lines in vitro. We have recently completed a single-institution clinical trial of rituximab plus fludarabine in 40 patients with either treatment-naive or previously treated LGL.
Brachytherapy Devices Reduce Postlumpectomy RT Time
March 1st 2002CHICAGO-Brachytherapy devices that deliver radiation therapy directly to the lumpectomy site drastically reduce the time needed for radiotherapy after surgery for early-stage breast cancer, according to two studies presented at the 87th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
SMART Studies Two HAART Strategies for HIV
March 1st 2002BETHESDA, Maryland-A long-term study to determine which of two common strategies is better for treating HIV-infected individuals was initiated in January, as 21 US centers and several Australian sites began enrolling the first 1,000 patients. Participants in the SMART trial (Strategies for Management of Anti-Retroviral Therapies) are randomized to receive immediate, aggressive antiretroviral therapy ("hit-hard-early") or no HIV drugs until CD4+ T-cell counts fall below 250 cells/µL ("go-slow").
Response to Treatment With Rituximab in a Patient With Acquired von Willebrand Disease
March 1st 2002The patient is a 58-year-old woman (AA genotype) who was found to have a prolonged activated partial thromboplastin time (aPTT) of 65.7 seconds during a preoperative evaluation for spinal stenosis surgery and mild rectal bleeding. Her aPTT test repeatedly remained abnormally prolonged. The patient had an aPTT mixing study that did not correct immediately or at 2 hours (56.4 seconds vs control 29.7 seconds). Her bleeding time was also abnormally prolonged at 11 minutes.
Antibody-Targeted Chemotherapy Included in NCCN Oncology Practice Guidelines
March 1st 2002Wyeth-Ayerst Laboratories announced recently that thousands of patients affected by acute myeloid leukemia (AML) may benefit from the new National Comprehensive Cancer Network (NCCN) guidelines for the appropriate treatment of AML, including the use of gemtuzumab ozogamicin (Mylotarg) in specific clinical situations. The only antibody-targeted chemotherapeutic agent approved by the US Food and Drug Administration, gemtuzumab is indicated for patients with CD33-positive AML in first relapse who are 60 years of age or older and who are not considered candidates for other cytotoxic chemotherapy. The safety and efficacy of this agent in patients with poor performance status and organ dysfunction has not been established.
