I found this today on the Tripawds forum and wanted to throw it out there for folks who may be facing carboplatin therapy. Carboplatin is one of the primary drugs used for Osteosarcoma treatment. This could potentially make the treatment available to a larger number of folks.
The person posting is in Washington state, and had treatment beginning last month. The dog is 90 lbs and the treatment cost is $142 per treatment. For a comparison, Trouble's treatment started in December 2008, she was almost 70 lbs and the cost per treatment was close to $500. Wonderful news!
Sorry, my info is limited, but I was so excited to see this I had to share. Maybe some of the veterinary professionals would like to comment.
