A Massachusetts man has regained his voice after surgeons removed his cancerous larynx and, in a pioneering move, replaced it with a donated one.
Transplants of the so-called voice box are extremely rare, and normally aren91裸聊视频檛 an option for people with active cancer. Marty Kedian is only the third person in the U.S. ever to undergo a total larynx transplant 91裸聊视频� the others, years ago, because of injuries 91裸聊视频� and one of a handful reported worldwide.
Surgeons at the Mayo Clinic in Arizona offered Kedian the transplant as part of a new clinical trial aimed at opening the potentially lifechanging operation to more patients, including some with cancer, the most common way to lose a larynx.
91裸聊视频淧eople need to keep their voice,91裸聊视频� Kedian, 59, told The Associated Press four months after his transplant 91裸聊视频� still hoarse but able to keep up an hourlong conversation. 91裸聊视频淚 want people to know this can be done.91裸聊视频�
He became emotional recalling the first time he phoned his 82-year-old mother after the surgery 91裸聊视频渁nd she could hear me. 91裸聊视频� That was important to me, to talk to my mother.91裸聊视频�
The study is small 91裸聊视频� just nine more people will be enrolled. But it may teach scientists best practices for these complex transplants so that one day they could be offered to more people who can91裸聊视频檛 breathe, swallow or speak on their own because of a damaged or surgically removed larynx.
91裸聊视频淧atients become very reclusive, and very kind of walled off from the rest of the world,91裸聊视频� said Dr. David Lott, Mayo91裸聊视频檚 chair of head and neck surgery in Phoenix. He started the study because 91裸聊视频渕y patients tell me, 91裸聊视频榊eah I may be alive but I91裸聊视频檓 not really living.91裸聊视频�91裸聊视频�
Lott91裸聊视频檚 team reported early results of the surgery Tuesday in the journal Mayo Clinic Proceedings.
The larynx may be best known as the voice box but it91裸聊视频檚 also vital for breathing and swallowing. Muscular tissue flaps called vocal cords open to let air into the lungs, close to prevent food or drink from going the wrong way 91裸聊视频� and vibrate when air pushes past them to produce speech.
The first two U.S. larynx transplant recipients 91裸聊视频� at the Cleveland Clinic in 1998 and the University of California, Davis, in 2010 91裸聊视频� had lost their voices to injuries, one from a motorcycle accident and the other damaged by a hospital ventilator.
But cancer is the biggest reason. The American Cancer Society estimates more than 12,600 people will be diagnosed with some form of laryngeal cancer this year. While today many undergo voice-preserving treatment, thousands of people have had their larynx completely removed, breathing through what91裸聊视频檚 called a tracheostomy tube in their neck and struggling to communicate.
Although the earlier U.S. recipients achieved near normal speech, doctors haven91裸聊视频檛 embraced these transplants. Partly that91裸聊视频檚 because people can survive without a larynx 91裸聊视频� while antirejection drugs that suppress the immune system could spark new or recurring tumors.
91裸聊视频淲e want to be able to push those boundaries but do it as safely and ethically as we can,91裸聊视频� Lott said.
Head-and-neck specialists say the Mayo trial is key to helping larynx transplants become a viable option.
91裸聊视频淚t isn91裸聊视频檛 a 91裸聊视频榦ne-off,91裸聊视频�91裸聊视频� but an opportunity to finally learn from one patient before operating on the next, said Dr. Marshall Strome, who led the 1998 transplant in Cleveland.
This first attempt in a cancer patient 91裸聊视频渋s the next important step,91裸聊视频� he said.
Other options are being studied, noted Dr. Peter Belafsky of UC Davis, who helped perform the 2010 transplant. His patients at high risk of larynx loss record their voice in anticipation of next-generation speech devices that sound like them.
But Belafsky said there91裸聊视频檚 91裸聊视频渟till a shot91裸聊视频� for larynx transplants to become more common while cautioning it likely will take years more research. One hurdle has been achieving enough nerve regrowth to breathe without a trach tube.
Kedian was diagnosed with a rare laryngeal cartilage cancer about a decade ago. The Haverhill, Massachusetts, man underwent more than a dozen surgeries, eventually needing a trach tube to help him breathe and swallow 91裸聊视频� and struggled even to muster a raspy whisper through it. He had to retire on disability.
Still the once gregarious Kedian, known for long conversations with strangers, wouldn91裸聊视频檛 let doctors remove his entire larynx to cure the cancer. He desperately wanted to read bedtime stories to his granddaughter, with his own voice rather than what he called robotic-sounding speech devices.
Then Kedian91裸聊视频檚 wife Gina tracked down the Mayo study. Lott decided he was a good candidate because his cancer wasn91裸聊视频檛 fast-growing and 91裸聊视频� especially important 91裸聊视频� Kedian already was taking antirejection drugs for an earlier kidney transplant.
It took 10 months to find a deceased donor with a healthy enough larynx just the right size.
Then on Feb. 29, six surgeons operated for 21 hours. After removing Kedian91裸聊视频檚 cancerous larynx, they transplanted the donated one plus necessary adjoining tissues 91裸聊视频� thyroid and parathyroid glands, the pharynx and upper part of the trachea 91裸聊视频� and tiny blood vessels to supply them. Finally, using new microsurgical techniques, they connected nerves critical for Kedian to feel when he needs to swallow and to move the vocal cords.
About three weeks later, Kedian said 91裸聊视频渉ello.91裸聊视频� Soon he91裸聊视频檇 relearned to swallow, working up from applesauce to macaroni and cheese and hamburgers. He got to say hi to granddaughter Charlotte via video, part of his homework to just keep talking.
91裸聊视频淓very day it91裸聊视频檚 getting better,91裸聊视频� said Kedian, who moves back to Massachusetts soon. His tracheostomy remains in place at least a few more months but 91裸聊视频淚91裸聊视频檓 pushing myself to make it go faster because I want these tubes out of me, to go back to a normal life.91裸聊视频�
And just as Lott had assured him, Kedian retained his beloved Boston accent.
