Experimental Drug Destroys Liver Cancer

Mon Jul 15, 2002

MONDAY, July 15 (HealthScoutNews) -- An experimental drug with a taste for energy-thirsty cells appears to kill off liver tumors in rabbits.

Johns Hopkins University scientists found the chemical, known as 3-bromopyruvate, destroys liver cancer and also shrinks tumors that have spread from that organ into the lungs. The substance, which is related to a molecule that occurs naturally in the breakdown of sugar, starves cancerous cells of energy, but appears to leave healthy tissue alone.

Studying Lung Cancer Genes May Help

Sun Jul 14, 2002

By RANDOLPH E. SCHMID, Associated Press Writer

WASHINGTON (AP) - Studying the genes active in early stage lung cancers may help identify which patients are at greatest risk of dying, allowing their doctors to prescribe more aggressive treatment, researchers report.

A team led by Dr. David G. Beer at the University of Michigan found that by studying which of about 50 genes in an early stage tumor are more or less active, it could predict which patients are more likely to relapse within five years.

Screen May Detect High-Risk Lung Cancer

Mon Jul 15, 2002

By Merritt McKinney

NEW YORK (Reuters Health) - Michigan scientists have developed a method of identifying which patients with early-stage lung cancer might benefit most from aggressive treatment.

Though the screening, which looks for genetic markers of aggressive cancer in tumor cells, is not yet ready for widespread use, the analysis eventually may help patients with high-risk cancers live longer, according to researcher Dr. David G. Beer.

Many Cancer Patients Use Complementary Therapies

LONDON (Reuters Health) - More than half of all cancer patients are using complementary or alternative therapies to cope with the difficult side effects of hospital-based treatment, according to a report released on Sunday.

The market consultancy, Datamonitor, said as many as 60% of cancer patients in certain European countries, and 80% in the United States, use special diets, vitamin supplements, herbal remedies or acupuncture.

Many Patients Miss Mole Growth, Study Finds

Mon Jul 8,  2002

By Charnicia E. Huggins

NEW YORK (Reuters Health) - Patients who can identify changes in the size and shape of their moles can help their doctors to spot melanoma, the deadliest form of skin cancer, at an early and more treatable stage. But study findings show that many people seem to be unable to determine whether or not their moles are enlarging.

Discovered: How Omega-3 Fatty Acids Cut Cancer Risk

For years, scientists have recognized that nutrients known as

omega-3 fatty acids, which are commonly found in fish oil, offer significant protection against colon cancer.

Now, researchers at the University of Texas Medical Branch at Galveston (UTMB) have figured out how these compounds tend to keep the colon cancer-free -- a discovery that may also have implications for prevention and treatment of many other kinds of cancer.

The reason, according to a paper the UTMB scientists published June 10 in The Journal

Cancer Death Rate Higher in Poor Men Versus Rich

Tue Jun 18, 2002

NEW YORK (Reuters Health) - While wealthier US men were more likely to die of cancer than poorer ones during the 1950s and 1960s, this trend was reversed in the 1970s and 1980s, a new analysis of census data shows.

The findings could lead to better cancer education and screening campaigns, and could also help gauge the effectiveness of current programs aimed at reducing cancer rates, according to Dr. Gopal K. Singh and colleagues at the National Cancer Institute in Bethesda, Maryland.

Chemotherapy May Paradoxically Trigger Future Cancer

By medinews.com staff writer:

April 15, 2002

Research has revealed that some drugs used in chemotherapy may actually cause conditions that can lead to the future growth of a cancerous tumor.

Chemotherapy drugs work by interfering with the ability of cancer cells to divide and reproduce themselves. The affected cells become damaged and eventually die. As the drugs are carried in the blood, they can reach cancer cells all over the body.

Unlimited Tanning Packages May Raise Cancer Risks

Mon Jun 24, 2002

By Charnicia E. Huggins

NEW YORK (Reuters Health) - Tanning salons that offer unlimited tanning may be giving consumers more tan for their money, but they're also promoting excessive exposure to ultraviolet radiation (UV), according to a team of California researchers.

Prior studies have suggested that overexposure to artificial UV rays may increase an individual's risk of melanoma, the deadliest form of skin cancer.
