100409 - Aging population increases cancer cases.  Older people living longer
100410 - with good medical care suffer increasing infirmaties that require new
100411 - treatments, reviewed previously on 020221. ref SDS 1 Y27F  This
100412 - Malthusian demographic dilemma seems evident in the interview today...
100413 -
100414 -            DR.  BARKER:  ...cancer will take the lives of 1,500 people
100415 -            today; 560,000 people will die from this disease this year;
100416 -            and nearly 1.5 million people will receive a diagnosis of
100417 -            cancer this year.  That's really - those statistics are
100418 -            really daunting, but if you look forward into the future,
100419 -            and not that far into the future, 12, 15 years even, we
100420 -            could see an increase of cancer approaching 50 percent in
100421 -            some estimates, certainly in the 30 percent range, and from
100422 -            30 to 50 percent means an enormous number of increase in
100423 -            cancer cases. ref OF 1 CH4N
100425 -             ..
100426 -            So today about one out of three Americans can expect to get
100427 -            cancer.  And if you look at the aging of the population,
100428 -            the number of cancer cases will increase significantly.

100432 - Biomarkers, like CA 15-3 that aids Millie's treatment, illustrate
100433 - dilemma.  Researches estimate 100,000 to 1,000,000 cancer markers need
100434 - to be discoved and deployed.  So far, 1261 have beed identified, and
100435 - FDA has approved 9 for patient care, ref SDS 0 3O6O, in part because
100436 - approval takes 10 years and a billion dollars. ref SDS 0 TD5L

190408 -            Sometimes to measure changes following treatment.
190409 -            Biomarkers can be changes in genes, changes in proteins,
190410 -            some combination thereof.  It can even be imaging, for
190411 -            example.  Images can qualify as biomarkers if it's

230420 -            actually have to be developed by isolating them, finding

230422 -            are your body's response to an antigen or a foreign

450407 -            DR.  WOODCOCK:  Cancer is probably the most promising field
450408 -            right now for biomarkers, and from FDA's point of view, I
450409 -            think biomarkers are the future of medical therapy, both

450414 -            New biomarkers get to the mechanism of cancer.  They get to
450415 -            the actual causes in the cancer cells of what's gone wrong,
450416 -            why they've turned into cancer cells.  They provide a lens,
450417 -            a new way of looking at people so we could determine they
450418 -            have cancer earlier, diagnose earlier, as well as pick the
450419 -            right treatment. ref OF 2 5J61
450421 -             ..
450422 -            DR.  WOODCOCK:  Biomarkers can be turned into diagnostic
450423 -            tests, of course, and those tests can be used to either
450424 -            detect, for example in cancer, detect a tumor much earlier
450425 -            than the kind of tests we use now, or they can be used to
450426 -            direct therapy.  Or they can be used to say you are a
450427 -            patient who is at high risk for a side effect, and we
450428 -            shouldn't give you this therapy.  So biomarkers can really

470414 -            actually get in the hands of doctors and patients.  FDA

470420 -            DR. WOODCOCK:  Biomarkers are extremely important in the

470422 -            biomarkers to predict whether or not a product is going to

520420 - could identify cancer shows a lot of work will be required to apply

520429 -            Not all associations are true predictors, and so a lot of

520431 -            volunteers and so forth to determine whether or not these

520446 -            like a cancer biomarker, and testing for reliability is
520447 -            called validation, or biomarker qualification.  It's a very
520448 -            difficult process to gather up enough information about the
520449 -            performance of the test in a real world situation to verify

520453 -            Clinical trials test patients who may have a disorder, and
520454 -            patients who don't have a disorder in order to see if
520455 -            testing produces accurate, consistent results.  Genetic
520456 -            variability between people causes different effects taking
520457 -            aspirin.  A lot of people are helped by aspirin, but some
520458 -            are not.  Similar variability occurs with biomarkers and
520459 -            other drugs affecting patients differently.  Therefore,
520460 -            testing must yield acceptably low numbers of false
520461 -            positives when the patient is not afflicted, and also yield
520462 -            low numbers of false negatives for patients who are
