A trial at the University of Pennsylvania’s school of veterinary medicine is introducing a groundbreaking treatment for dogs suffering from osteosarcoma. Dogs in the trial are receiving an experimental vaccine that trains the immune system to recognize tumor cells and to kill them- and it’s working!
More than 10,000 dogs are diagnosed each year with osteosarcoma, which is an aggressive type of bone cancer. Most dogs die within a year of diagnosis, but in this trial, many of the dogs in the study have survived for more than two years. Check out this video to see an update on Denali, a therapy dog enrolled in the trial.
The biology of canine osteosarcoma is the same as the biology of these tumors in children, so the information gained from this study could one day help children with osteosarcoma. There are also types of breast cancer that have similarities to osteosarcoma, so the human benefits aren’t limited to one type of cancer.
Researchers are looking for more dogs with osteosarcoma to participate in this trial. Does your dog qualify? If so, check out the link here for more information.
The first therapeutic vaccine for cancer has been conditionally licensed by the USDA! And man’s best friend will benefit from it. This vaccine is intended as a treatment for dogs with stage II or stage III oral melanoma, and hopefully, it will dramatically improve the quality of life for pets suffering from this type of cancer.
Canine oral melanoma is very aggressive and can be difficult to treat. Melanoma tumors contain a protein called tyrosinase, and the vaccine works by introducing human tyrosinase into the dog’s body, which stimulates an immune response against the protein.
Because canine oral melanoma affects a small percentage of the dog population, using a vaccine as a treatment instead of a preventative seems to be the best option at this point. But if veterinarians were able to determine certain breeds or populations of dogs that were at risk, it’s possible that this treatment could be modified for use as a preventative vaccine.
By starting with a vaccine treatment for oral melanoma, it’s possible that this could lead to the development of vaccine treatments for other types of cancer. Interestingly, this development first began with basic animal research, moved into research in human treatments, and now it’s back to animals by benefiting man’s best friend! Who knows- this may lead to the development of human melanoma treatments. Read more about it here:
