For six hours, Dr. Peter Baginski lay wide awake in the tunnel of a magnetic resonance imaging machine in a Zurich hospital while sporadic pulses of focused ultrasound penetrated his skull and slowly burned a hole through the inch-long tumor deep in his brain.
The procedure was painless, but his head felt "almost unbearably hot," Baginski said, even though cold water circulated through a helmet-like device designed to moderate the temperature.
A team of 10 people, including three Swiss neurosurgeons, monitored the unprecedented procedure on March 4 to treat glioblastoma, a rare but deadly cancer of the brain.
That night, Baginski, a Forestville physician who turns 64 today, enjoyed a splendid dinner in his hospital room, surrounded by his wife, Cheryl Hanson, and five family members. He was fit enough to leave the next day but remained at the hospital for a week, allowing his doctors to monitor their human guinea pig.
Baginski, who already had beaten the odds by surviving five years with a cancer that usually kills in 13 months, became the first and only person to undergo successful focused-ultrasound treatment for a brain tumor.
Successful in the sense it did him no harm. Baginski's procedure was part of a Swiss clinical trial to assess the safety — not the effectiveness — of the treatment that advocates say could revolutionize treatment of brain tumors and other cancers.
Out of caution, the doctors limited his exposure to ultrasound, burning a single hole in the tumor. Four days later, they were pleased to see more holes, with the tumor resembling a piece of Swiss cheese.
"Peter took a leap of faith," said Hanson, his wife of 39 years, sitting at the dinner table in their home near the end of a quiet west county lane.
Baginski, who speaks slowly and sparingly because of mid-brain damage from the tumor, said it was merely a safe bet.
"I had nothing to lose, actually," he said. "Just a lot of money, but everything to gain."
