BOSTON Sen. Edward Kennedy has been released from Massachusetts General Hospital and is heading for his home on Cape Cod after being diagnosed with a cancerous brain tumor.
The 76-year-old Kennedy waved to a crowd of well-wishers and gave a thumbs-up as he walked out of the hospital amid heavy security. His dogs greeted him at the hospital door.
Doctors said Wednesday the Massachusetts Democrat "has recovered remarkably quickly" from a brain biopsy conducted Monday. Kennedy will recuperate at his Hyannis Port home while the doctors await further test results and determine his treatment plan.
Kennedy has a malignant glioma in his left parietal lobe. Experts say such tumors are almost always fatal.
The news of Kennedy's diagnosis reverberated Tuesday across the spectrum of U.S. politics.
Sen. Orrin Hatch, R-Utah, was visibly shaken after the Republican caucus lunch meeting, when he learned the news.
"I love him like a brother," Hatch said, wiping tears from his eyes. "I just feel terrible about hearing this. It's really terrible news."
Hatch has been e-mailing with Vicki Kennedy, the senator's wife, since Kennedy suffered a seizure over the weekend. Kennedy's staff members, who know how close the two are, also have been keeping him in the loop, Hatch said.
"We've just been very, very close," Hatch said. "We've always respected each other."
President Bush, as well as all three presidential candidates, paused to pay tribute to the Massachusetts Democrat's legislative achievements.
"Ted Kennedy is a man of tremendous courage, remarkable strength and powerful spirit. Our thoughts are with Senator Kennedy and his family during this difficult period. We join our fellow Americans in praying for his full recovery," Bush said.
Sen. Barack Obama, D-Ill., who received Kennedy's backing for the Democratic presidential nomination, said he might not be a member of the Senate had it not been for Kennedy's work on voting rights and civil rights. Sen. Hillary Clinton, D-N.Y., called him one of the greatest legislators in Senate history.
And Sen. John McCain, R-Ariz., Kennedy's chief co-sponsor on an unsuccessful overhaul of immigration laws, blinked back tears on his campaign bus as he called Kennedy "the last lion in the Senate."
"I have held that view because he remains the single most effective member of the Senate if you want to get results," McCain said.
Senate Majority Leader Sen. Harry Reid, D-Nev., said Kennedy's wife has said the senator is in "really good spirits" and was walking around Tuesday.
"He knows how we feel about him, without our even telling him. ... " Reid said. "And so we stand as a body, and as certainly a Democratic family, with our affection, our love and our prayers with Senator Ted Kennedy."
GOP presidential candidate Sen. John McCain, R-Ariz., called Kennedy "the single most effective member of the Senate."
"Obviously, our thoughts and prayers go out to his family and to him. We hope and pray that they will be able to treat it and that he will experience a full recovery. I have said on numerous occasions, I have described Ted Kennedy as the last lion in the Senate," McCain said.
Hatch said he is going to "pray real hard" for Kennedy's recovery and "demand" that his friend get better to return to his work in the Senate.
"I've been praying, and I'll continue, and I'll step it up a notch," Hatch said. "I thought I was praying pretty hard as it was, but I'll step it up a notch."
Sen. Bob Bennett, R-Utah, also expressed his concern, although he does not have the same type of relationship with Kennedy.
"Unlike Sen. Hatch, I do not share any committee assignments with Sen. Kennedy and therefore have not really developed the close relationship that Sen. Hatch has developed," Bennett said. "At the same time, with all the senators, my thoughts and prayers are with Sen. Kennedy and his family at this time of difficulty."
Kennedy was elected to the Senate in 1962 at age 30 to take the place of his brother, John F. Kennedy, who had become president. Now 76, he is the third-longest-serving senator in history, behind Sen. Robert Byrd, D-W.Va., and the late Sen. Strom Thurmond of South Carolina.
The medical course of action for Kennedy's cancer depends on exactly what form of glioma he has, whether surgeons can cut most of it out, age and some other medical details.
Kennedy's doctors didn't mention surgery, suggesting that may not be a possibility for him.
"As a general rule, at 76, without the ability to do a surgical resection, as kind of a ballpark figure you're probably looking at a survival of less than a year," said Dr. Keith Black, chairman of neurosurgery at Cedars-Sinai Medical Center.
On the plus side, scientists are studying new approaches adding a drug called Avastin to standard treatment, or even brewing up customized vaccines to help the body fight back. While they're still experimental, many glioma experts advise newly diagnosed patients to seek out specialized cancer centers and ask if they're a good candidate for a research study up front.
"Considering how poorly they do despite standard treatment, it is always best to seek a clinical trial," said Dr. Deepa Subramaniam, director of the brain tumor center at Georgetown University's Lombardi Comprehensive Cancer Center. "They are not likely to do worse."
Kennedy was hospitalized Saturday after a seizure. Tuesday, doctors at Massachusetts General Hospital announced the reason, a malignant glioma in his left parietal lobe, a brain region that governs sensation but also plays some role in movement and language. Doctors were awaiting further tests before choosing treatment, but they cited radiation and chemotherapy as the usual approach.
Kennedy's age and the mention of upfront chemotherapy mean the glioma is almost certainly one of the two worst forms: a glioblastoma the fastest-killing brain tumor, known for claiming entertainer Ethel Merman and Republican political strategist Lee Atwater or the only somewhat less aggressive anaplastic astrocytoma, Subramaniam said.
Malignant glioma "usually is a synonym for a glioblastoma," agreed Dr. Robert Laureno, neurology chairman at Washington Hospital Center in the nation's capital.
The American Cancer Society puts the five-year survival rate for patients over age 45 at 16 percent for those with anaplastic astrocytomas, and 2 percent or less for those with glioblastomas.
Patients fare best when surgeons can cut out all the visible tumor, Black said. That isn't a cure doctors know they're leaving cancerous cells they just can't see.
But about 40 percent of the time, surgery isn't an option. The cancer, which digs tentacle-like roots into normal brain tissue, may be too deep or located so closely to critical brain regions.
Moreover, "it doesn't help to take 50 percent or 60 percent of the tumor out," Black said.
Standard treatment is about six weeks of fairly high-dose radiation along with a chemotherapy pill named Temodar, and then additional Temodar for at least six months or until the tumor stops responding.
The older the patient, the worse the prognosis. But some people fare much better especially those with a subtype where another glioma form, called oligodendroglioma, is mixed with the primary tumor, Black said. They generally survive three times as long as people with pure glioblastomas.
The tumor's size which also wasn't revealed is key, too, added Dr. Lynne Taylor of Seattle's Virginia Mason Cancer Center and the American Academy of Neurology. An 8-centimeter tumor is pretty big for chemo and radiation to blunt, while a 1cm tumor is easier.
Also, the fairly recent addition of Temodar has brought a slight increase in the number of patients who beat average survival odds, she added.
"You're fighting an uphill battle," is what Taylor tells her patients and then immediately urges them to live as if they'll be one of the lucky ones.
Whatever the statistics, the news is grim. And what symptoms will appear first depends on exactly where in the parietal lobe the tumor sits and "how that individual's brain is wired," Laureno said.
Among the possibilities: Loss of sensation on the right side of the body, problems with movement in the right arm and leg, eventual problems speaking or even vision problems in the right eye.
There are some experimental therapies that researchers are watching closely, including:
• Adding the colon cancer drug Avastin to standard treatment. Avastin chokes off tumors' blood supply, and initial studies suggest it can help shrink gliomas. Whether that helps survival isn't yet known, but Black says even though this use is experimental, more and more specialists are prescribing it right after diagnosis.• Trying experimental cancer vaccines. Brain tumors often can't be seen by the immune system. So scientists take cells from the surgically removed glioma, put them on the immune cells and give them back to the patient. Small studies at Cedars-Sinai suggest the approach improved two-year survival from 8 percent of glioblastoma patients to 42 percent, Black said. But it's only an option for surgery candidates.
