First the facts: This year, 130,000 Americans will learn that they have developed a tumor somewhere in the inner lining of their colon or rectum. For those whose cancer is discovered at the earliest stages, the odds of living at least five more years are greater than 90%. Unfortunately, fewer than 40% of colorectal cancers are discovered that soon. In the same period, about 56,000 people in the U.S. will die of the disease, making it the second greatest cancer killer, after lung cancer...
...Medical School's Andrus Professor of Pediatric Surgery M. Judah Folkman announced last Friday that tests at his lab at the Children's Hospital had confirmed the effectiveness in mice of the protein fragment, called antiangiogenic antithrombin (aaAT), in suppressing the formation of blood vessels that feed tumor growth...
This discovery comes less than two years after Folkman published his lab's detection of the second of two protein fragments thought to suppress tumor growth. The three fragments have only been tested in animals, and it will be impossible to judge the potential of these substances in fighting human cancers until extensive clinical trials are held, at least...
...implanting human tumors into mice and comparing tumor growth, scientists can try to identify which types of human tumors could possibly be used in future to inhibit cancers, according to the Science article...
Mallinckrodt Professor of Chemistry George M. Whitesides '60 suggested that disparity between labs' results may stem from the different ways they are trying to relate the vascular system's growth to tumor growth...
