VA Acts on Agent Orange Link to Type of Leukemia

WASHINGTON —  Researchers have found a link between a type of leukemia and exposure to herbicides such as Agent Orange, prompting the Department of Veterans Affairs to announce Thursday it will extend benefits for Vietnam veterans with the illness.

The veterans diagnosed with chronic lymphocytic leukemia, or CLL, will start receiving improved benefits, such as disability compensation and priority health-care services, in about a year, Secretary Anthony J. Principi said Thursday.

“It’s sad that we have to presume service connection, because we know that [veterans] have cancer that may have been caused by their battlefield service. But it’s the right thing to do,” Principi said.

Veterans Affairs expects to find about 500 new cases of CLL a year among Vietnam veterans, said spokesman Phil Budahn. About 2.6 million people served in Vietnam during the war, and most are still alive.

There are 10,000 Vietnam veterans receiving disability pay for other illnesses related to exposure to Agent Orange and other herbicides used during the war, Veterans Affairs said.

The Institute of Medicine, which reexamined past research on cancer rates in agricultural workers and farm community residents, announced Thursday that it had found the link between the form of leukemia and Vietnam-era herbicides.

“It’s just one more indication that service on the battlefield exposes men and women to dangers beyond bullets, shrapnel and missiles,” said Principi, who requested the review. “Environmental hazards are as worrisome and deadly as some of the more common forms of battlefield injury.”

U.S. troops sprayed 20 million gallons of Agent Orange and other herbicides over parts of South Vietnam and Cambodia in the 1960s and ‘70s to clear dense jungle. Some veterans reported a variety of health problems shortly after returning from the war.

Some forms of cancer, Type 2 diabetes and birth defects in veterans’ children are considered associated with herbicide exposures during the war. But it has been difficult to research the problem because no one knows how much troops were exposed to, the Institute of Medicine said.

“For more than two decades, we’ve had many complaints from Vietnam veterans about serious problems from Agent Orange exposure, and it’s taken a long time to have sufficient proof to satisfy the VA and now we have it,” said Sen. Arlen Specter (R-Pa.), Senate Veterans Affairs Committee chairman.

By connecting the defoliant and CLL, the Institute of Medicine altered its own previous finding that not enough scientific evidence existed to establish a connection. The institute is part of the National Academy of Sciences.

Previously, researchers lumped CLL with other forms of leukemia when looking at cancer rates among Vietnam veterans. This time, the scientists examined rates of CLL separately, said Dr. Paul Engstrom, a member of the review committee and a vice president with Fox Chase Cancer Center in Philadelphia.

The scientists said that although CLL is a form of leukemia, it shares some similarities with Hodgkin’s disease and non-Hodgkin’s lymphoma, two diseases that have long been known to be associated with exposures to the types of chemicals used in Agent Orange and other defoliants.

Although health care is available to nearly all veterans, Principi’s decision means that veterans with CLL who were in Vietnam during the war will get disability compensation of about $2,300 a month, won’t have to pay co-payments for health care to treat CLL and will have better access to the agency’s health services. Principi must draft rules and publish them in the Federal Register before the benefits can take effect.
