Guidelines target stem cell medical tourism

Some clinics are taking advantage of desperate patients, says an international group of stem cell scientists.

Growing numbers of clinics abroad are marketing unproven, costly stem cell therapies to medical tourists and "exploiting patients' hopes," according to a report from the International Society for Stem Cell Research.

The Deerfield, Ill.-based group convened a task force of researchers, ethicists, doctors and regulatory officials from 13 countries to devise guidelines that target clinics offering experimental therapy to patients without appropriate transparency, oversight or patient protections.

"There is this tension between the slow progress of medical science and the desperation of patients and the swiftness with which disease overtakes them," said Laurie Zoloth, PhD, on the task force that issued the report in December 2008. "Combine that with a flat world and the Internet, and it's a recipe for stem cell fakery."

Restrictions on federal funding for embryonic stem cell research have contributed to the trend, said Zoloth, director of the Northwestern University Feinberg School of Medicine Center for Bioethics, Science and Society.

"Americans could be lured into other countries because of their recognition that stem cell research might be held back here," Zoloth said.

The average cost for stem cell treatment overseas is $21,500.

The number of patients who have traveled abroad for stem cell therapies is unknown, though experts said that anecdotally it appears to be in the thousands. That represents a sliver of the 750,000 Americans who left the U.S. for medical care last year, according to the Deloitte Center for Health Solutions.

Josef Woodman, author of the medical tourism guidebook Patients Beyond Borders, said he has yet to come across a patient traveling abroad for stem cell therapy but said he would advise patients to steer clear. "It's unproven and experimental," he said. "There are plenty enough challenges with medical travel as it is."

The proliferation of clinics marketing purportedly effective stem cell interventions online has many experts worried. A December 2008 study of stem cell clinics' Web sites found that they claimed to treat a range of diseases that go beyond the scope of the early evidence on stem cells' efficacy, while playing up the benefits and talking little about risks. The study, published in the journal Cell Stem Cell, found that the average price tag for the treatments, excluding travel and lodging costs, was $21,500.

"We're not presuming they're all quacks. Maybe they genuinely believe in what they're doing," said Timothy Caulfield, a study author and the Canada Research Chair of Health Law and Policy at the University of Alberta. "But if the stuff really works, let's see the data. They need to be as transparent as possible. We need more than just testimonials."

The American Medical Association in July 2008 adopted principles on medical tourism, calling for patient choice, informed consent and continuity of care. In 2003, the AMA adopted policy supporting "federal funding for research involving human pluripotent stem cells."
