I finally got the report from Auburn….this is from Dr Henderson…the pathology report is kind of long too…I have it typed up if anyone would like for me to post it here.
When Wilson was at Auburn he had a 4 year student…she was wonderful….she is here in Mobile working with the vet that I was going to use for chemo….I called her and I will be taking Wilson to that vet on Tuesday for x-rays and will be talking to them more about this report since they are more informed about Canine Cancer….they have the same digital x-ray that Auburn has and my vet does not.
I will be calling Dr Henderson or sending a email to him to see if he got a 2nd opinion.
The final diagnosis is" Fibrosarcoma, intramedullary, femur
Recommendation: This is not a common biopsy report. Fibrosarcoma is most common in large (giant breed dogs) like Wilson and do not have the same early metastic risk as osteosarcoma. Unfortunately because there are fewer fibrosarcomas, we have less experience in their biological behavior. To quote VROM the current textbook on Clinical Oncology, "(amputation) may be curative, although metastatic potential may be considerable. "This is not very reassuring"
I have shared this pathology report with the VSSO (Veterinary Society of Surgical Oncologists) listserve this afternoon. The opinion will be that we should obtain a 2nd opionion on the pathology and begin chemotherapy in the interim if the thoracic radiographs remain clear of metastases.
This is my summary: We may have cured this neoplasm with amputation. If the owner is an optimist and wishes the least chance for medically induced disease, we should leave well enough alone. if a pessimistic approach is taken, that there is significant risk for metastasis (or that this is really varient of osteosarcoma), then there should be confirming clear chest x-rays and begin an administration of chemotherapy probably alternating doxoruicin and carbolatin for 4 to 6 doses (although some would choose one or the other of these drugs and be correct). cisplatin is another drug that could be included or substituted for the carboplatin.
I would like to give clear direction, but there is not a correct answer for Wilson. Often I am asked what I would do for my own pet in this situation. I would not give chemotherapy and just enjoy every day I am given. We are likely to outlive most of our pets and it is the living well that brings joy.
