...decades the only true weapon against colon cancer has been surgery. If the scalpel could take out the entire tumor, the patient was cured; if not, the cancer recurred. But now, for the first time, researchers have developed a drug therapy that may reduce the high death rate from this form of cancer, which kills 53,500 Americans each year and is the third most common type of malignancy...
...coordinated by Dr. Charles Moertel of the Mayo Clinic in Rochester, Minn., researchers tested a combination of two drugs: 5- fluorouracil, a proven anticancer agent, and levamisole, a medication commonly used by veterinarians to clear worms from the intestines of animals. Included in the studies were some 1,700 cancer patients, most of whom had been operated on for Dukes' C colon cancer. In this stage of the cancer, the tumor has penetrated the bowel wall but has not spread to the rest of the body. The results of the first study, which appeared in this month's Journal...
...researchers caution, however, that the drugs are not effective for patients with more severe colon cancer, in which the malignancy has already spread throughout the body. Nor have studies shown a benefit for those patients whose cancers were detected at an early stage. Still, Dr. Michael Friedman of the National Cancer Institute called this first success for drug therapy against colon cancer a "terrific intellectual breakthrough." The institute has alerted 35,000 cancer doctors across the country. And some experts are hopeful that the findings will lead to similar therapies for other cancers...
Opponents charge that a disaster during launch could spew large amounts of radioactive fallout throughout Florida and cause 2,000 cases of lung, bone and liver cancer. The danger, they say, does not end with a successful takeoff. To gather momentum, the Galileo spacecraft will first make a swing around Venus and two around the earth before hurtling off to Jupiter. Critics are concerned that the vehicle could collide with the earth during close flybys...
...have seemed more eager to denounce the alternative fuels than to develop new products. Mobil has run ads attacking methanol as polluting, expensive and more dangerous than gasoline if accidentally swallowed. Although the fuel produces far fewer smog ingredients than gasoline, it releases more formaldehyde, a suspected cause of cancer. Cars would get less mileage from methanol because it burns faster than gasoline. Yet Indianapolis 500 racers have used methanol for years because it boosts horsepower and is less flammable in accidents; U.S. automakers have developed experimental cars that run on both methanol and gasoline...
