Radiation Oncology Overview

Radiation therapy is a non-surgical approach to achieving local tumor control and increasing a pet’s quality of life, quantity of life, or both. A targeted dose of radiation is delivered to the tumor with the intent to destroy the cancer cells, which are unable to repair themselves. The safety and efficacy of utilizing radiation to shrink a tumor or impede its growth have improved significantly in recent decades

 

The VMCLI is proud to provide advanced radiation therapy to the pets of Long Island. Since 2004, the VMCLI clinicians have been at the forefront of emergency and specialty medicine for pets, and are excited to be able to offer this new modality for pets with cancer.

 

Radiation Oncology Services Include:

 

Stereotactic radiation (SRS/SRT), sometimes referred to as stereotactic radiosurgery (SRS) or stereotactic radiation therapy (SRT), is the most advanced form of radiation therapy currently available. The biggest difference between SRS/SRT and other forms of radiation therapy is the unprecedented precision, which means that a higher dose of radiation can be delivered directly to the tumor. At the same time, the surrounding healthy cells can be avoided more effectively than ever before, decreasing the frequency and severity of radiation-related side effects in most cases. SRS/SRT is delivered in just 1-3 treatment sessions with no incisions and minimal time under anesthesia. It is especially useful to treat tumors that are too big or too complex for surgery.

 

Conventionally fractionated radiation therapy (CFRT) uses targeted radiation to shrink or destroy tumors, including those that cannot be safely or completely removed by surgery alone. While SRS/SRT utilizes complex treatment-planning to deliver high-dose radiation in just a few treatment sessions, CFRT requires less complex treatment-planning and delivers smaller doses of radiation spread out across more treatment sessions and a longer period of time. It can be used in conjunction with chemotherapy, following surgery, or as the sole treatment in cases where SRS/SRT is not an option. CFRT is typically administered daily in 15-21 treatment sessions over 3-4 weeks.

 

Palliative radiation therapy is intended to increase a pet’s comfort and quality of life, often when local tumor control is deemed unlikely. This option is especially useful when treatment options with the intent to cure, such as SRS/SRT or surgery, are not viable. Palliative treatments are typically delivered once per week over 3-6 weeks with the goal of relieving symptoms such as pain, bleeding, and decreased mobility.
