Sparky Begins Chemotherapy

Sparky's knee is healing pretty well ~ he can put some weight on it and even walk a few steps on a level surface. The fluid cytology came back and confirmed that it is indeed chyle, which is caused by leakage from the thoracic duct or one of the lymph vessels that drain to it. The most common causes are a tumor, a trauma, heartworm disease, or right-sided heart failure.

We know he has a mass - the most common mediastinal (middle of the chest) tumors are either a lymphoma or a thymoma. One can be reduced and managed with chemotherapy while the other one can't; surgery is just not an option for this sweet ol' guy either. So, after quite a bit of discussion with our internist Dr. Slusser, and our holistic veterinarian Dr. Laflin, we've opted to try chemotherapy. If the tumor is due to lymphoma, it should respond to the chemo by reducing in size, which will keep the fluid from building back up in his chest. If it's not, well, we'll cross that bridge when we need to.

Sparky received a dose of vincristine today, a small intervenous injection, and also had his chest tapped again. Today, we removed 1400mls from it, and he was feeling much better afterward! He has a recheck in a week, and we'll evaluate how well it worked.
