Hi, all, My kuvasz girl's (Nefi's) tumor turned out to be a fibrosarcoma, not a perianal carcinoma as the vet had thought, so I've been reading about fibrosarcoma and have found out the following
--common in dogs and cats --locally invasive, slow growing --no site predilection --metastasis is rare --may become quite large before any clinical signs are apparent. We will probably be following up the surgery with chemotherapy and have a choice of protocols involving single agents or combinations of agents. If anyone is knowledgeable about fibrosarcoma (the research) and/or has had experience with it, could you contact me and let me know if your experience/research has indicated that a particular protocol is more effective than others? Whichever of the following protocols we choose, we would repeat the cycle every 21 days for 4--6 treatments. The choices of protocols are 1. Doxorubicin alone 2. Mitoxantrone alone 3. AC Protocol (Doxorubicin & Cyclophosphamide) 4. VAC Protocol (Vincristine, Doxorubicin, Cyclophosphamide) Thanks for any help/info! After surgery, Nefi is doing quite well--back to her old self: lively, protective, happy--and her incision is healing up nicely. Her blood tests and xray indicate no metastasis. Christy Kabler
