I'm posting this in case anyone in
cyber land has to go through the same thing I have these last few weeks. I have googled and
wikipedia'd this topic quite
obsessively. I have read the trials, and studies and lived through it.
Mira is having a tumor (a viral
papilloma) removed for the second time. These tumors usually grow in young dogs and usually occur on the face or mouth, but rarely can occur on the feet, in between the pads, as in Mira's case. In healthy dogs the tumors are self limiting and will regress in several
months.
Recurrence is a sign that there is an underlying autoimmune problem. In Mira's case the vet is not convinced of this as she has been otherwise healthy, shiny coat, etc. We are crossing our fingers and paws. Remember nothing is black and white there are always shades of grey.
They are
surgically removing the tumor again but this time they are modifying the procedure with hopes to prevent another
recurrence. She will be on a round of
zithromax (an antibiotic) and possibly some antiviral cream (
Aldara). If it comes back again we will try
cryotherapy (freezing) or chemotherapy. There has been some evidence that surgical removal during the growth phase actually
stimulates more growth and the study advised postponing surgery until the mass reached it
maximum size or started to regress. I'm not sure if this thing can get bigger, but I can't wait any longer as it is impeding her walking. I also read that you can crush the tumor in small sections which stimulates cell death, but this would be very painful and not an option for a dog like Mira. There is also information on manufacturing a vaccine from a section of the tumor but it has lead to cancer in that area later on.
In the end, the chemotherapy was described to me as not a very good option, showing less then positive results.
Cryotherapy is relatively obsolete in small animals and they play a guessing game with how long to freeze the area. Too long and the bone can die leading to
permanent damage and future surgeries.
The best evidence is with the antibiotic
zithromax which has potential to become mainstream therapy, even over surgery. I'm not sure how this works as the tumor is viral and antibiotics work on bacteria, but it was described to me that it was working by a different mechanism to kill the tumor other then antibacterial. It's cheap and non invasive so it can't hurt to try.
I hope that this information is helpful for others who are going through this.
Say good-bye to Mira's little friend
