...Skin cancer is now as common as all other cancers combined, says a new study. Up to 1.2 million cases of nonlethal malignancy turn up every year, along with some 32,000 cases of potentially lethal malignant melanoma. The numbers are still on the rise...
Since my 37-year-old wife was killed by malignant melanoma 1 1/2 years ago, news of how cancer may be attacked has passed through my mind with a sigh and a feeling that it just doesn't matter anymore. I am cynical when I read of "advances" in cancer treatment, though I am inspired by the work of scientists. Their efforts, combined with education on preventive measures, ( give me hope that others may not have to live through the same atrocity...
...tumors survive the turbulent voyage through the bloodstream, notes experimental oncologist Ann Chambers of the London Regional Cancer Centre in Ontario. But those that do eventually slip through blood-vessel walls with ease. Using a video camera attached to a microscopic lens, Chambers has watched in wonder as melanoma and breast-cancer cells, injected into mice, become lodged in capillary walls, then crawl out into the liver. Three days later, her camera resolves the spidery shapes of tiny metastatic growths. The lesson, Chambers believes, is depressingly clear. Cancer cells zip in and out of blood vessels so readily that, once...
...Molecule of the Year. But now there is a new contender for notoriety -- MTS1, as Alexander Kamb and his colleagues refer to the multiple tumor- suppressor gene they have just discovered. "Multiple" refers to the fact that defects in this gene can cause many kinds of cancer, including melanoma, lung, breast and brain tumors. In fact, functional copies of MTS1 may be missing in more than 50% of all human cancers...
...protrude from tumor cells like spikes on a medieval ball and chain. At the meeting of the American Society for Cancer Research last week, Dr. David Berd of Thomas Jefferson University presented the most encouraging evidence to date that the vaccine strategy may work. Berd told of inoculating 47 melanoma patients with a vaccine made of their own tumor cells inactivated by radiation. Three years later, 60% remained tumor-free, compared with 20% in the unvaccinated control group. The approach works best, apparently, in patients who have tumors small enough to be surgically removed but whose disease shows signs...
