Is Electro-Chemotherapy the Magic Bullet Pet Owners Have Been Seeking?
Used to treat specific tumours, the jury is still out for my dog, but to date, the results have been pretty encouraging.
As I’ve mentioned in past, my dog Lexie has cancer. It started as a bump on the side of her snout that wouldn’t heal and was ultimately diagnosed as a Squamous Cell Carcinoma. Surgery removed it, and all was good for more than two years.
Then it came back on her eyelid. Again, a small wart-like sore that grew quickly and was surgically removed. But six months later, it was back again, and we were running out of eyelid skin for removal. Again, surgery was completed, and Lexie now looked like she’d had a bad facelift. Aesthetics aside, the good news was that the latest biopsy detected no cancer cells in the surrounding tissue. Yay!
Six weeks later, it was back with a vengeance.
So now, we were talking about alternative treatment – the most desperate being the removal of her eye. I did my homework and asked about radiation, given chemotherapy seemed to be used primarily on internal cancers versus isolated lesions. While it was an option, the veterinary oncologist advised that radiation treatment would damage surrounding tissue and could only be done once, with an alternative required should the cancer come back.
Now, I’ve lost pets in the past due to natural causes as well as those with cancers that required euthanasia. I’m optimistic but also realistic, and my Lexie was still a happy, healthy dog with a love of snacks, treats, dog parks and meeting new faces. A battery of bloodwork, x-rays, and tissue samples confirmed no spread of the disease. Beyond this ugly growth, she was a perfectly healthy dog.
That’s when the oncologist suggested something relatively new - Electro-Chemotherapy.
In discussion with the clinic that would be performing the treatment, I was advised that Lexie would be injected with chemo and exactly seven minutes later, electronic pulses would be directed into the tumour (40 zaps in total for Lexie). This would cause blood to pool for a nano-second and the chemo chemicals to be drawn to the site rather than dissipate throughout her system.
Ultimately, the tumour becomes necrotic (essentially turning to pulp and breaking down). And yes, it looks and smells as bad as that sounds. Unlike human chemotherapy, there were no side effects for my dog. No nausea or diarrhea (which can happen with some pooches). She’s had two sessions to date, and the tumour that was growing so rapidly has not only stopped growing but has decreased in circumference and depth by a full centimeter.
She’s scheduled for a final treatment sometime within the next two weeks, and we’re hopeful it will be enough to keep the cancer at bay for the next year or longer.
Electro-chemotherapy is used to treat cancers that can be tricky to remove surgically – such as on the paws, in the mouth, and on the face or eyelids. According to Frontiers in Veterinary Science, electro-chemotherapy “…is an effective and safe treatment modality, which is not only beneficial as a palliative treatment, but also for a curative approach”.
It isn’t cheap, but if you’re exploring all options for your pet and want to be aware of new treatments and tests, it’s worth speaking to your veterinarian about.
And here’s hoping this third time is a charm for Lexie!
