so far, the results of this experimental genetic study are encouraging. dr. pegram: we see no evidence of recurrence of the ovarian cancer following her gene therapy treatment. but patients will continue to be monitored to determine the long-term results of this new treatment technology. another class of drugs, known as angiogenesis-inhibiting drugs, also hold great promise in the ongoing battle with cancer. these drugs cut off the blood supply to tumors, depriving them of the nouriment necessary for growth. dr. glaspy: the angiogenesis-inhibiting drugs... there are a lot of them out there. some of them have exciting pre-clinical data. they're in early clinical trials, and they may sort of change this gameboard a lot for us. then we... get into the realm of experimental treatments, drugs like herceptin, which... attack something that's different about a cancer cell, and make that cell either stop growing, or make it more sensitive to treatment with the other modalities. in 1986, the scientific community learned that a gene involved in regulating cell growth h

attendees seemed to agree on is we need to put in place better research to track this at each experimental stage rather than waiting until it's ready for publication to make decisions about what can be revealed. and that's another question that i hope our panelists will discuss today. although this particular controversy about publication appears to have been resolved, it's going to recur. as osterholm said, we can't just kick the can down the road and deal with it on an ad hoc baseis. what systems are in place to monitor dual-use research that could produce dangerous results. what new systems are being put in place now. are more needed? and how do we balance these against our obvious valuation of the -- and valuing of the quest for knowledge, of free scientific inquiry. etched into the national academy of science's headquarters wall are the words of einstein, one of many words quoted often of einstein, the right to search for truth implies also a duty. one must not conceal any part of what one has recognized to be true, end of quote. but, of course, this matter before us this morning rais
