Head and neck cancer in transplant patients: For better or worse?

Source: medicalxpress.com Author: Henry Ford Health System staff Transplant patients who develop head and neck cancer are more likely to be non-smokers and non-drinkers, and less likely than their non-transplant counterparts to survive past one year of diagnosis, according to a new study from Henry Ford Hospital in Detroit. As part of a 20-year review, Henry Ford researchers found cancers of the throat, tonsils and mouth may be more aggressive in transplant recipients as the result of long-term immunosuppressive therapy required to prevent solid organ rejection. Transplant patients in the study who developed skin cancer in the head and neck region were more likely to have multiple lesions, compared to the general public. In all, 2.6% of transplant patients in the study developed some form of head and neck cancer. While the risk for developing head and neck cancer is small, the study serves as an important reminder to all transplant recipients to be vigilant about any changes to their skin, as well as persistent sore throat, ear pain or swallowing issues – all signs of head and neck cancer. "The benefits of organ transplantation and immunosuppressive therapy still outweigh the risk of transplant patients developing head and neck cancer," says study author Robert Deeb, M.D., with the Department of Otolaryngology-Head & Neck Surgery at Henry Ford. "Still, our study highlights that head and neck cancer arising in transplant patients warrants the need for regular screenings and aggressive treatment." The study will be presented Jan. 28 in Miami Beach at [...]

Using a lab-grown trachea, surgeons conduct the world’s first synthetic organ transplant

Source: www.popsci.com Author: Clay Dillow Surgeons working at Karolinska University Hospital in Sweden have taken a huge step forward for regenerative medicine by successfully executing the world’s first synthetic organ transplant. The donor-less transplant saved the life of a 36-year-old cancer patient, who is doing well now after having received a new windpipe grown from his own stem cells. This story is about as international as it gets: The Eritrean patient, Andemariam Teklesenbet Beyene, was pursuing his doctorate in geology in Iceland when his trachea was consumed by an inoperable tumor that grew so bad that it was actually blocking his breathing. So 3-D scans of his windpipe were sent to scientists at University College London, which crafted a glass scaffold that was a perfect match for Beyene’s trachea and two main bronchi. The scaffold was in turn was sent to Sweden, where it was soaked in stem cells from Beyene’s own bone marrow. The stem cells took hold and within just two days had filled the scaffold, creating a new trachea that is, biologically speaking, Beyene’s own tissue. A 12-hour operation by an Italian surgeon specializing in trachea operations removed Beyene’s windpipe and all signs of the cancer and then replaced it with the new, lab-grown organ. That was a month ago. Today, Beyene is recovering well. Because the organ was grown from his own cells, there is no risk of his body rejecting it and no need for the harsh regimen of anti-rejection drugs that usually go hand [...]

Surgeons carry out world’s first face, jaw and tongue transplant

Source: www.mirror.co.uk Author: staff Surgeons have successfully carried out the world's first face, jaw and tongue transplant. They spent 16 hours operating on a man of 43 whose face had been horribly disfigured by radiotherapy for a tumour 11 years ago. The patient will eventually be able to eat, taste, swallow and speak again. Pedro Cavadas, who led 30 Spanish medics in Valencia in the day-long op, said yesterday: "The patient's seen himself and is delighted." The case was marred by controversy after authorities released details about the donor against his family's wishes. French woman Isabelle Dinoire received the first face transplant four years ago after losing her nose, lips and chin when a dog mauled her.
