Veterinary Cancer Care is committed to furthering the field of oncology by participating in and initiating clinic trials research. In addition to collecting data on our own patients, Veterinary Cancer Care continually monitors new developments in cancer research. Being informed of the most recent progress in veterinary cancer and innovative methods of managing the disease is of tremendous benefit to our clients.

Intralesional Chemotherapy Clinical Trial

Intralesional chemotherapy is the administration of cancer fighting drugs directly into the tumor, tumor site, or adjacent tissues. The goal is to provide local tumor control by achieving high local chemotherapeutic drug concentrations. Because the chemotherapy is not given into a vein, the side effects tend to be few. The advantages are ease of administration, low risk of side effects, low cost, and the option for subsequent treatments in the event of a tumor recurrence.

For additional information regarding the use of intralesional chemotherapy to treat acanthomatous ameloblastoma in dogs please see our publication:

Intralesional 5-Fluorouracil treatment for Soft Tissue Sarcoma in dogs

Soft tissue sarcomas (STS) are a group of similarly behaving cancers that account for 15% of the tumors of skin and subcutaneous tissue in dogs. The most effective treatment for STS is wide surgical excision (removing the tumor and several centimeters of the surrounding tissue) followed by radiation. Radiation can be logistically challenging and financially challenging. 5-Florouracil (5-FU) is a commonly used systemic chemotherapy drug that has shown promise as a local (intralesional) treatment alternative to radiation. At Veterinary Cancer Care we are concluding a six-year preliminary trial of intralesional 5-FU post-surgery in dogs with STS. If proven effective, this would provide a lower cost alternative to radiation therapy available to all veterinarians. We hope to publish results in the near future. While we compile data for publication we are continuing to offer this treatment.

For currently published results using 5-FU in dogs with STS see the following publication:
