    #1003: Interphone cellphone health study on hold

    Cellphone health study on hold

    As cellphone use grows around the world, concerns about the devices’ safety
    are resurfacing.

    Other nations have released their data on wireless health effects, so why
    hasn’t Canada?

    It’s supposed to be the mother of all studies into cellphones and their
    potential link to head cancers, a definitive report that the
    multibillion-dollar wireless industry has partially funded.

    But the published analysis of the 13-country Interphone study is two years
    late and likely to be delayed further as the more than 50 scientists
    involved bicker over how to interpret the results, knowing full well that
    any hint at health risks would have a profound impact on the industry.

    The stakes are high, and the steps toward the final outcome are being
    closely watched. More than three billion people around the world use a
    cellphone, and while sales next year are expected to fall slightly amid
    tough economic times, wireless gadgets like the BlackBerry and iPhone are
    woven into the fabric of our daily lives.

    Participating countries are free to publish their individual national
    results, and eight countries have.

    Among Nordic countries, there are already hints that cellphone use for 10
    years or longer increases the risk of developing glioma and acoustic
    neurinoma tumours on the side of the head where a handset is held.

    It’s far from definitive, but suggestive enough to spark closer scrutiny
    from some scientific corners. Growing impatient and citing the public’s
    right to get “the whole pattern,” a group of scientists calling themselves
    The BioInitiative Working Group are urging the remaining five countries “”
    including Canada “” to hand over their results “without further delay.”

    “There is a lot of data that’s been obtained, but not all of it, and the
    people sitting on it are being obstructionists for a particular reason,”
    said Dr. Martin Blank, a professor of cellular biophysics at Columbia
    University in New York City and one of 11 scientists who signed a letter
    earlier this month asking for speedy release of the data.

    None of the five countries, including Australia, New Zealand, Israel and
    Italy, has complied with the request. The scientists heading up Canada’s
    portion of Interphone haven’t even responded.

    “They don’t want the results to come out. It’s as simple as that,” said

    Three cities are part of the Canadian study: Ottawa, Montreal and Vancouver.
    The Canadian Wireless Telecommunications Association, which has consistently
    maintained that cellphones are not harmful to use and comply with all
    Canadian safety standards, contributed $1 million to the Ottawa portion
    through a third-party organization.

    However, the association said it isn’t aware of when the results will be
    published and doesn’t know the reason for the delay.

    “I have no idea why the full Interphone study has not been released,” said
    spokesperson Marc Choma. “Interphone does not report to us.”

    Dr. Daniel Krewski, a professor in the department of epidemiology and
    community medicine at the University of Ottawa, is heading up the Ottawa
    study. He did not reply to an interview request, either directly or through
    his office.

    In a May interview, however, Krewski told the Star there was a concern that
    certain biases in the Interphone results “” such as study subjects
    overestimating their long-term cellphone use “” may be skewing the analysis.

    His counterpart in Montreal, Dr. Jack Siemiatycki at the University of
    Montreal, told the Star in an e-mail exchange last week that the
    BioInitiative Working Group has no greater or lesser claim to the data than
    anyone else.

    “There are no people in the world who want to see the Interphone results
    published more than the Interphone collaborators ourselves,” Siemiatycki

    “It has proven very difficult to achieve an agreed upon manuscript for

    The reasons are “not sinister,” he assured. “They have to do with facts and
    data that can legitimately be interpreted in different ways.”

    Asked why Canada hasn’t released an analysis of its own data as eight other
    countries have, Siemiatycki said it was agreed at the outset that Canada
    would release its study after Interphone is published. For this reason the
    Canadian data, while collected, has not yet been analyzed.

    “And doing so won’t be a trivial task,” he added.

    Australia and Israel have also not published their national Interphone
    results, but the scientists heading up each country’s research have said
    publicly, including in interviews with the Star, that there are concerning
    patterns emerging for long-term use.

    It’s part of the reason why Toronto Public Health and the University of
    Pittsburgh Cancer Institute, in what some considered a controversial move,
    both recommended this summer that children minimize their use of cellphones
    and use headsets as a precaution.

    Blank isn’t surprised there’s a concern.

    “I think there’s going to be a building up of momentum,” he said.
