WASHINGTON (Reuters) - Dr. Judah Folkman, a giant of cancer research who discovered that tumors generate a network of tiny blood vessels to nourish themselves, has died at the age of 74, Harvard Medical School said on Tuesday.
Folkman's work founded an entire branch of cancer research called anti-angiogenesis therapy. His theory was that if a tumor could be stopped from growing its own blood supply, it would wither and die.
The theory helped in the development of such drugs as Genentech's Avastin and other targeted cancer therapies.
"This is devastating loss to not only our hospital family, but the world at large," Dr. James Mandell, president and chief executive officer of Children's Hospital in Boston, where Folkman was based, said in a letter to staff.
"Dr. Folkman, founder and director of the Vascular Biology program, was a true visionary and scientific pioneer. Because of Dr. Folkman's vision, more than 10 new cancer drugs are currently on the market, and more than 1.2 million patients worldwide are now receiving anti-angiogenic therapy."
Folkman was born in Cleveland, Ohio, in 1933 and graduated from Ohio State University in 1953. He earned his medical degree at Harvard Medical School in 1957 and stayed there for much of the rest of his career.
Folkman said he came up with his theories while serving in the U.S. Navy in the early 1960s, at the National Naval Medical Center in Bethesda, Maryland.
DEFINITIVE PAPER
He published his definitive paper in the New England Journal of Medicine in 1971. It took nearly a decade for the scientific community to accept his ideas.
"I was there when he first began to present those ideas and they were shouted down by very famous people," said Dr. David Nathan, president emeritus of Harvard's Dana-Farber Cancer Institute.
Nathan said Folkman worked patiently and politely to battle critics of his angiogenesis theories.
"He was kind and he was decent and he was friendly always, even to his critics," Nathan added in a telephone interview.
"Judah had the most creative mind, ceaselessly creative. You could not have a conversation with Judah without having him think of the problem in a different way. He was just bubbling over with new ideas in many areas," Nathan said.
One of Folkman's interests was the understanding that people with Down's syndrome are much less likely to have cancer than the general population. He suggested it might have something to do with the third copy of chromosome 21 -- the hallmark and underlying cause of the condition.
"Down syndrome is always considered a tragedy for families. But on the other hand, they bring this huge clinical clue," " Folkman told Reuters in an interview published January 2, when he was asked to comment on some recent research on the subject.
Folkman called back after the story was published, distraught that families of Down's patients had been calling him and e-mailing him about the comment. "They thought I meant that I thought their children's lives were a tragedy," Folkman said.
"I have been talking to each family and explaining to them what I meant. We all know that people with Down syndrome can lead full lives now, and that these children are as much a blessing as any other child," he said.
No cause of death was given. Folkman was married and had two daughters and a granddaughter.

Judah Folkman, MD, founder and director of the Vascular Biology program at Children's Hospital Boston, was a true visionary and scientific pioneer. When he first proposed, in the 1970s, that a cancer could be kept in check by cutting off its blood supply, he faced skepticism and even ridicule from a scientific community that simply wasn't ready for his ideas. But he persevered, even when there were setbacks, and today, more than 1,000 laboratories worldwide are engaged in the study of angiogenesis, the field he founded. Because of Dr. Folkman's vision, more than 10 new cancer drugs are currently on the market, and more than 1.2 million patients worldwide are now receiving anti-angiogenic therapy. Dr. Folkman was also a compassionate doctor, always willing to take calls from cancer patients anywhere in the world, and always passionate about trying to improve their care. A healer and teacher, he has surely lived up to the advice of his father, a rabbi, that he become "a rabbi-like doctor."
