Diagnostic Tests

Does a test that promises to detect ovarian cancer sooner really do so? Could other tests nearing the market prolong survival by getting patients the right care faster? A race is on for blood tests to better detect this intractable killer, but the Food and Drug Administration is probing whether to crack down on the first one to sell. It's a time of both hope and confusion. First, the question is whether testing giant LabCorp jumped the gun in selling OvaSure as an ovarian cancer screening test before researchers proved that it caught the tumor in an early, treatable stage without falsely alarming too many healthy women.

A new way to test for cervical cancer is more accurate than a pap smear and identifies more dangerous lesions, according to an Italian study published Tuesday. Researchers used the traditional test for the human papilloma virus that causes cervical cancer and combined it with another that indicated specific cancer-causing activity in cells. The test looked for a protein called P16INK4A, which indicates cell changes that show a woman probably has precancerous lesions, the team reported in the journal Lancet Oncology.

Men over the age of 75 should no longer be screened for prostate cancer because the potential harm from the test results -- both physical and psychological -- outweighs any potential benefit from treatment, a federal panel said Monday. Most oncologists already argue against treating most men in that age group for prostate cancer because they are more likely to die from some other cause than from their tumor.

People with Alzheimer's face an awkward juncture in the near future. They'll be able to learn early on whether they have Alzheimer's disease -- even if they can't do much about it. With therapies to halt or slow the progression of Alzheimer's disease seeming ever more elusive, several blood tests currently in development could determine who has the disease even before symptoms develop or become severe.

The VA Greater Los Angeles Healthcare System began offering 20-minute HIV tests at its downtown ambulatory care center Tuesday -- part of a campaign to encourage more veterans to get tested and treated for the virus. "HIV testing is the gateway to life-saving therapy," said Dr. Earl Tso, a primary care physician who is leading the downtown center's outreach effort. In the past, veterans wanting to be tested for HIV had to have blood drawn and sent to a laboratory for analysis.

Medical experts recommended Wednesday that a less-invasive procedure known as a virtual colonoscopy and a stool DNA test join the arsenal of screenings for colon cancer in the hopes that more people would get checked out. The recommendations bring to six the number of screening tests suggested for spotting signs of colon cancer, said Dr. Otis Brawley, national chief medical officer of the American Cancer Society, one of the groups that made the recommendations.

When it comes to medical care, my husband and I generally call the shots in our family. Most people would agree that this is an appropriate role for us to play, but certain medical decisions aren't normally the purview of parents. Nor should they be. Foremost among them is the decision to screen children for some genetic diseases. During the last 25 years, the number of genetic tests has increased rapidly.

Annual screening with a technique called transvaginal ultrasound, coupled with a blood test for CA125, a protein that can be elevated in the setting of ovarian cancer, does not reliably detect ovarian cancer early, at a more curable stage, a new study finds. "We and other groups confirm that the current method of ovarian screening, which is a combination of ultrasound scans and [blood] markers, is ineffective," said Dr. Emma R. Woodward of Birmingham Women's Hospital in Britain.

HIV testing will soon become part of routine prenatal care and be required for some newborns under a new law that supporters say is putting the state in the forefront of the national fight against HIV transmission to babies. Acting Gov. Richard J. Codey signed the measure into law at University Hospital in Newark. The law will take effect in six months. "We can significantly reduce the number of infections to newborns and help break down the stigma associated with the disease," Codey said.

NEW YORK -- With human growth hormone emerging as the drug of choice for baseball players, Rep. Henry A. Waxman (D-Beverly Hills) said Friday he would consider federal funding to support the search for an effective HGH test. That prospect cheered Dr. Don Catlin, the former UCLA scientist charged by baseball with developing a urine test for HGH. "I'd certainly put my hat in the ring for a grant," said Catlin, who now runs the Anti-Doping Research Institute in Los Angeles.
