Families skeptical of findings in company's cancer inquiry

HARTFORD, Conn. -- For jet engine maker Pratt & Whitney, a long-simmering dispute over worker illnesses was settled by a massive 11-year study partly done by the University of Pittsburgh that found no elevated risk of brain cancer at its plants. But for dead workers' relatives who first raised concerns years ago, the matter is far from closed.

Their next step hasn't been decided, and the choices are limited. Matt Shafner, a New London, Conn., lawyer who represents families, said more than 90 workers' compensation claims have been filed. But he won't move forward until an independent review of the study is completed, he said.

"It's not over," said Carol Shea, whose husband, John Shea, worked at Pratt & Whitney's North Haven plant for 35 years and died of brain cancer in 2000 at age 56.

Some relatives of workers who died of brain cancer a decade or more ago are dissatisfied with the study, saying it failed to prove that the deaths of their loved ones were part of a broader problem.

Todd Atcherson, whose father, Charles Atcherson, died in 1998 after working at Pratt & Whitney for about 25 years, said the enormous scope of the study -- health and work records of more than 200,000 employees were reviewed -- fail to explain the deaths of his father and a small group of other workers at the North Haven plant.

"They skewed out the numbers so far, they lost focus of five people who worked in the same site and all died," he said.

The study, released last month, was launched "in response to the perception of an unusual occurrence" of glioblastoma, a common and aggressive malignant brain tumor, at the North Haven plant.

It found the incidence rates of glioblastoma at the site weren't related to workplace exposures.

The study, which examined seven other Pratt & Whitney plants in Connecticut, found no statistically significant elevations in the rate of cancer among workers.

Researchers at Pitt and University of Illinois at Chicago said they identified 723 workers diagnosed with tumors between 1976 and 2004 at the subsidiary of United Technologies Corp.

The tumors were malignant, benign or unspecified and included 277 cases of brain cancer. Of those, 167 were at Pratt & Whitney's East Hartford site and 57 at North Haven, though North Haven workers were at greater risk of having brain cancer, the study said.

But following a study of the North Haven plant, researchers said they couldn't conclude that the environment or exposures were related to the overall elevations in brain cancer.

Gary Marsh, the Pitt researcher who led the study, said that he understands family members' frustrations but that the study is conclusive and definitive.

Ray Hernandez, a spokesman for Pratt & Whitney, said the company is satisfied with the study's conclusions and considers the matter closed.
