My happy Christmas Dog! |
In the case of osteosarcoma the most aggressive approach to treatment is amputation of the effected limb and injectable chemotherapy. This will buy your dog 10-12 months.
If your dog is not a good candidate for amputation, you can consider a limb spare procedure depending on where the tumor is. There is a surgical procedure where they remove the tumor and replace it with a plate and/or bone graft. There is also a special type of radiation called stereotactic radiosurgery that will kill the tumor. This type of radiation is only done in a few places. Colorado State and University of Florida are two, there may be more in the USA that I am not aware of. A limb spare procedure plus injectable chemotherapy will buy your dog 10-12 months.
Just amputation without chemotherapy gains an average of 3 months.
Palliative radiation is a type of radiation that just relieves the pain, but doesn't kill the tumor. Palliative radiation plus injectable chemotherapy plus a bisphosphonate (a drug that helps build bone strength) may give your dog about 9 months.
All these projections are based on a dog WITHOUT evidence of metastases in the lungs. Unfortunately when there is gross evidence on x-rays that there are nodules in the lungs you can subtract about 3-4 months from all these estimates.
So what to do? With Christmas coming there is going to be a delay no matter what procedure we choose. I need some time to digest the information and make a decision. Until we decide on the next step I am controlling Cody's pain with the following drugs: Tramadol (a pain killer related to morphine), Previcox (a non-steroidal anti-inflammatory), and Gabapentin (a seizure medication that is thought to help with neurologic pain). Cody has also been wearing a pain patch of Fentanyl since his biopsy procedure. Fentanyl is 100 times stronger than morphine. He seems pretty comfortable with the patch on, but I hope I can do something more to treat the pain.
онкология это I would like to say that this blog really convinced me to do it! Thanks, very good post.
