Thursday, ending 11 years of research, the incidence of brain tumors in the state's jet engine manufacturer Pratt & Whitney University researchers say they found no cancer rates among workers in a statistically significant increase.
At the University of Pittsburgh and the University of Illinois at Chicago researchers say they identified tumor diagnosis and United Technologies Corporation's subsidiaries in 1976 and 2004 between the 723 workers. Tumors were malignant, benign or uncertain, and includes 277 cases of brain tumors.
The researchers examined records, such as working papers and cancer registries 222,123 men and women who worked in 1952 and 2001, one or more eight Connecticut Pratt & Whitney plants. They also reviewed 11 chemical or physical agents, based on known or suspected carcinogenic potential, it may affect the central nervous system or other organs.
$ 12 million for research, Pratt & Whitney commissioned by the State Department of Public Health is responsible for supervision. William Gerrish spokesman for the state agency, saying it was a "comprehensive study has reached its goal," the project's lead researcher, said the results were positive.
, Who led the study, researchers at the University of Pittsburgh Gary Marsh said: "The good news,."
Employees can rest assured that Pratt & Whitney in 2002, before the study period began, "do not increase the risk of developing brain cancer, does not increase your risk of death," Marsh said.
A Pratt & Whitney worker's son, who died at 46 years old was not so sure, though.
"It leaves a lot of questions unanswered," said Todd, his father, died in 1998 after 25 years at Pratt & Whitney for about Charles Atcherson, Atcherson.
Workers and trade unions expressed concern that several workers died of brain cancer research each other within a few years become too large, "neglect" of individuals, he said.
Paul Dickes, chief machinists union, which represents Pratt & Whitney workers' health and safety representative said that his assurance, research to determine it is safe to work, and the remaining two Connecticut plants.
"It will not bring closure have the disease," he said. "I am disappointed that it does not solve these problems."
Pratt & Whitney spokesman Ray Hernandez, said: "We are delighted to have their employees answer to the question, there is no cancer and the relationship between the workplace."
The researchers said, comparing the Pratt & Whitney plant in North Haven factory workers between tumors and showed a slightly higher incidence of cancer. But further evaluation did not find the estimated workplace exposure.
Marsh said, slightly higher incidence of cancer in North Haven plant may reflect external occupational factors, the researchers did not like other company's employees or job factors unique to North Haven measurements.
He said the study is one of the largest and most comprehensive professional environment. It is also the first large-scale study, the jet engine manufacturing industry workers.
The results echo the three phase of the study published in 2008 the first phase. Then, the researchers said, they found no statistically significant excess of malignant brain tumors among workers killed in North Haven.
Workers and their families, by the machinists union to participate in research, pushed back the widow and union officials said they feared the death seem like Pratt & Whitney is one of many plants.
