Kennedy recovering; chemo, radiation ahead

RALEIGH, North Carolina (AP) -- Sen. Edward Kennedy enjoyed "a restful night's sleep" and was walking hospital hallways Tuesday, one day after undergoing an aggressive brain surgery aimed at slicing away at a cancerous tumor to give chemotherapy and radiation treatments a chance to work.

"Senator Kennedy had a restful night's sleep and is recuperating well from yesterday's procedure," his office said in a statement. "He is experiencing no complications and has been walking the hallways, spending time with family and actively keeping up with the news of the day.

"He looks forward to returning home to Cape Cod soon, and is thankful for all the prayers and well wishes."

The 76-year-old senator is expected to stay at Duke University Medical Center in Durham for about a week before returning to Massachusetts for further treatment. No further updates on Kennedy's condition were expected until he leaves the hospital, according to the statement.

Kennedy was diagnosed with a malignant glioma in the left parietal lobe of his brain after suffering a seizure May 17 at his home in Hyannis Port, Massachusetts. He underwent 3½ hours of surgery Monday at Duke, where doctors provided few details about the surgery, including how much of the tumor was removed.

But Kennedy's doctor deemed the procedure a success that "accomplished our goals." When Kennedy emerged, he told his wife, Vicki, that he felt "like a million bucks," according to a family spokeswoman.

In the following days, Kennedy will probably be given drugs to prevent brain swelling and seizures, which are possible complications of the surgery. The senator also will be closely watched for bleeding and blood clots, because strokes are also a risk, though they are uncommon.

"After a brief recuperation, he will begin targeted radiation at Massachusetts General Hospital and chemotherapy treatment," his doctor, Dr. Allan Friedman, said in a statement after Monday's procedure. "I hope that everyone will join us in praying for Sen. Kennedy to have an uneventful and robust recovery."

The sole surviving son of America's most glamorous and tragic political family learned last month that he had a malignant glioma, an often lethal type of brain tumor.

Details about Kennedy's exact type of tumor have not been disclosed, but some cancer specialists have speculated that it is a glioblastoma multiforme -- an especially deadly and tough-to-remove type -- because other kinds are more common in younger people. iReport.com: Young prodigy beats brain cancer

Cutting a tumor down -- or "debulking" it -- is extremely delicate because of the risk of harming healthy brain tissue that governs movement and speech. But Friedman, who is the top neurosurgeon at Duke and an internationally known tumor surgeon, said Kennedy should not experience any permanent neurological effects.

The outlook for patients with malignant gliomas is poor and depends on what type of glioma a patient has. Median survival for glioblastomas is 12 to 15 months, but the range is wide, said Dr. Mark Gilbert, a brain tumor expert at the University of Texas M.D. Anderson Cancer Center in Houston. iReport.com: The shock of receiving a brain cancer diagnosis

Doctors have not revealed Kennedy's treatment plan, but typical radiation treatment is five days a week for a month, using 3-D imaging techniques that narrowly deliver the beams to the tumor, affecting as little surrounding tissue as possible.

Kennedy also most likely will receive the chemotherapy drug Temodar during and after radiation. It can cause typical chemo side effects -- nausea, vomiting and fatigue -- but treatments are much better for these than even a few years ago, doctors stressed.

He also may be treated with Avastin, a newer targeted drug to deprive the tumor of its blood supply, though this is still experimental as initial treatment, rather than after patients have relapsed.

Monday's operation "spells nothing but hope," Dr. John Sampson, associate deputy director of Duke's brain tumor center, said from Chicago, Illinois, where he was attending a conference of 30,000 cancer specialists. "What we're seeing with the surgery and this conference is that there's hope for patients with this kind of cancer."
