Laparoscopic Ultrasound Probe Provides Important Information During Abdominal Laparoscopic Surgery
August 1st 1996Although laparoscopic surgery is a less invasive technique for abdominal surgery, a drawback is the fact that it visualizes only the surface of the abdominal cavity and may miss abnormalities within solid abdominal organs, such as the liver. The use of
Immunologists Share Alfred P. Sloan, Jr., Prize for Outstanding Contributions to Cancer Research
August 1st 1996dvances in cell biology and basic science are made in step-by-step increments of understanding, achieved over years of painstaking research. While not usually typical headline-grabbing material, such research has led to some of the most important
Two Biochemists Win Charles S. Mott Prize for Outstanding Research in Cancer Causation or Prevention
August 1st 1996Damage occurs to our genes every day, some of it due to chemical or physical agents that have the potential to cause mutations leading to cancer. Luckily, cell proteins detect such damage and repair it before the cell reproduces, preventing a
Researchers Propose New Treatment Guidelines for HIV
August 1st 1996VANCOUVER, BC--The new understanding of the importance of viral dynamics in the progression of HIV infection (see "New Thinking on HIV Progression Leads to New Strategies") has led to new guidelines for deploying drugs now available to treat HIV (a list of available agents is on page 13). Experts now recommend reducing viral load to below detectable limits, as an indication that viral replication has been curtailed as much as possible.
FNA Dropped From RDOG Study Due To High Rate of Insufficient Samples
August 1st 1996DALLAS--Fine-needle aspiration (FNA) breast biopsies in women with mammographically apparent, nonpal-pable breast lesions were deemed impractical due to the high rate of insufficient samples in a Radiologic Diagnostic Oncology Group (RDOG) study, and were stopped 19 months into the trial, Etta D. Pisano, MD, said at the American College of Radiology (ACR) National Conference on Breast Cancer.
New Thinking on HIV Progression Leads to New Strategies
August 1st 1996VANCOUVER, BC--The new more aggressive approach to HIV infection, using antiviral drugs early and in combination, reflects not only the availability of new drugs but also the application of new thinking about HIV infection (see reports "Early Combination Treatment May Provide HIV Control" and "Researchers Propose New Treatment Guidlines for HIV"). Initial (primary) HIV infection causes an acute flu-like syndrome that is followed by years of relatively asymptomatic disease. This period of "clinical latency" had been thought to reflect viral latency, but work by David D. Ho, MD, and his colleagues at the Aaron Diamond AIDS Research Center, New York, has shown otherwise.
Hospitals Told Not to Capitate for 'Wrong' Reasons
August 1st 1996SAN DIEGO--There are many sound reasons why a medical center may want to capitate its oncology services and just as many wrong reasons, said Paul M. Kennelly, who recently assumed the position of president and CEO of the management services organization at the City of Hope Oncology Network in Southern California.
More Study Needed of Possible Carcinogenesis of Winter Gas Additive
August 1st 1996WASHINGTON--Although the chemical MTBE, added to gasoline in the winter to reduce the emission of carbon monoxide, does not pose a substantial human health risk, more study needs to be undertaken to assess both short- and long-term health effects, a National Research Council (NRC) committee said in its review of a draft of a federal report.
President Makes NCAB Appointments
August 1st 1996WASHINGTON--President Clin-ton has reappointed Barbara K. Rimer, DrPH, to a second 2-year term as chair of the National Cancer Advisory Board (NCAB) and appointed Richard J. Boxer, MD, professor of family and community medicine, Medical College of Wisconsin, Milwaukee, to a full 6-year term. Dr. Boxer had served on the board for a year to complete the term of Paul Calabresi, MD, who resigned to join the President's Cancer Panel.
National Program of Cancer Registries
August 1st 1996The American Cancer Society (ACS) estimates that more than 8 million Americans alive today have a history of cancer, of whom 5 million were diagnosed 5 or more years ago. Most of these 5 million can be considered cured, while others still have evidence of cancer. In 1995, about 1,252,000 new cancer cases were diagnosed. This estimate does not include basal and squamous cell skin cancers and in situ carcinomas except bladder. The annual incidence of these skin cancers is estimated to be more than 800,000 cases. There has been a steady rise in cancer mortality in the United States in the last half-century. In 1995, about 547,000 people died of cancer--more than 1,500 people a day. One out of every five deaths in the United States is from cancer.
Marketing of Cancer Services Must Include All Payer Modalities
August 1st 1996SAN DIEGO--Today when almost all payment and delivery models co-exist in every market, marketing approaches to cancer care services must respond to all payer models, including managed care and fee-for-service, said Karen M. Gilden, a senior consulting associate with Oncol-ogy Associates, Inc., Warrenton, Va, and the editor of Cancer Management.
Dr. Kessler Corrects Misapprehension That The FDA Cannot Regulate Tobacco Products
August 1st 1996BETHESDA, Md--Many people believe that the law under which the FDA regulates foods, drugs, devices, and cosmetics contains an exception for tobacco, but FDA Commissioner David A. Kessler, MD, told a symposium on tobacco addiction that this is not so, and that his agency plans to forge ahead with its proposed regulations.
New Surgical Techniques May Reduce Impotence, Incontinence
August 1st 1996ORLANDO--Impotence and incontinence, the radical prostatectomy complications that patients fear most, can be reduced through simple modifications in surgical technique without compromising cancer control, according to two reports presented at the American Urological Association's 91st annual meeting.
Early Combination Treatment May Provide HIV Control
August 1st 1996VANCOUVER, BC--Treatment for AIDS is beginning to resemble cancer therapy: Some studies suggest that best results occur when disease burden is reduced early by aggressive use of combination therapy. Previous thinking has been to hold effective antiviral agents in reserve until disease progression.Presentations at the 11th International Conference on AIDS showed that combination treatment, especially with regimens that include one of the new protease inhibitor drugs, can reduce the virus to undetectable levels in the blood. Reduced viral load decreases the risk of disease progression and is often followed by clinical and immunological improvement.Speaking at the meeting, Scott Hammer, MD, of New England Deaconess Hospital, Boston, pointed out that the ability of combination therapy to reduce viral load to undetectable levels means that "eradication of virus has become an acceptable hypothesis to be tested."Researchers at the Aaron Diamond AIDS Research Center are testing that hypothesis using aggressive combination treatment during primary infection.
Nurse Explains Start-up of Genetic Cancer Risk Assessment Program
August 1st 1996SAN DIEGO--With more than 200 known hereditary cancers syndromes, there is a clear opportunity for medical centers in this field, said LeeAnne Vandegriff, RN, cancer risk assessment coordinator at Harris Methodist Hospital, Fort Worth.
Number of US HIV Infections Steady
August 1st 1996BETHESDA, Md--The number of Americans infected with HIV is holding steady at about 650,000 to 900,000, according to CDC data. This may be because the number of new HIV infections each year is roughly equal to the annual number of AIDS-related deaths, the report said.
Kaiser Permanente to Evaluate Neopath's AutoPap 300 QC System
August 1st 1996REDMOND, Wash--NeoPath Inc has signed an agreement with Kaiser Permanente to install AutoPap 300 QC Systems at its Northern California facility. Following a successful evaluation, Kaiser Permanente anticipates making the technology available to its nearly 2.5 million Northern California members.
NCI Basic Research into HIV Structure Pays Off in AIDS Drug Development
August 1st 1996BETHESDA, Md--NCI research from the 1980s, in which scientists used crystallography to study the structure of the human immunodeficiency virus (HIV), paved the way for development of the current crop of HIV-specific protease inhibitors (see " Early Combination Treatment May Provide HIV Control" for a report on clinical trials of protease inhibitors).
Hospitals Under Pressure to Adopt Cancer Guidelines
August 1st 1996SAN DIEGO--Hospitals are facing tremendous pressures from the insurance industry to standardize treatments by adopting clinical practice guidelines, panel members said at a conference sponsored by the Society for Ambulatory Care Professionals and Health Technology Assessment of the American Hospital Association.
