Radiation Therapy
Injection site sarcomas or vaccine associated sarcomas are locally aggressive tumors that often recur following surgical removal. The average time for recurrence following surgical excision is 3 months. When surgery and radiation therapy are combined to treat this disease the median survival time is extended to two years. This is a tumor in which preoperative radiation therapy is considered optimal. Please consult a veterinary radiation oncologist to discuss further treatment options.
Mast cell tumors are
one of the most common skin tumors in the dog. Wide surgical excision
with 3 cm margins is often curative for grade 1 and grade 2 mast cell
tumors. If a wide surgical excision is n
ot
possible radiation therapy is used to control this tumor. Studies
have shown that 88% of dogs treated with a combination of surgery and
radiation therapy are disease-free at 5 years following treatment.
Meningiomas are the most common brain tumor seen in dogs. Treatment options consist of surgery, radiation therapy, or a combination of the two. A recent study has shown that the median survival time for dogs with meningiomas treated with radiation therapy is 20 months.
Nasal tumors in the dog are often diagnosed after chronic nasal discharge. Skull x-rays or CT scans can be suggestive of a nasal tumor, however, the diagnosis can only be confirmed with a biopsy. The treatment of choice for nasal tumors is definitive radiation therapy. Studies have shown that dogs with nasal tumors treated with radiation therapy have a median survival time of 1.3 years. Please consult with a veterinary radiation oncologist to discuss treatment options.
Oral melanomas are the
most common oral tumor in the dog. The traditional treatment for
this disease consists of a combination of surgery and radiation therapy. Studies
have described a median survival time ranging from 8 months to one year
following radiation therapy. A vaccine has
recently become available--the
oral melanoma vaccine is used in an attempt to prevent the spread of
the tumor. It is important that local control of the tumor be achieved
with a combination of surgery and radiation therapy prior to the administration
of the vaccine.
Soft tissue sarcomas consist of a group of tumors that share a similar biological behavior and a similar response to treatment. This group includes tumors such as Fibrosarcomas, Hemangiopericytomas , Nerve Sheath Tumors, and Myxosarcomas. Soft tissue sarcomas are locally invasive and rarely spread to other parts of the body. Surgical excision with 3-cm margins can be curative. If wide surgical margins are not possible radiation therapy is used control this tumor. Studies have shown that 76% of patients treated with a combination of surgery and radiation therapy are disease-free 5 years following the completion of treatment.
