The board-certified oncologists at SAGE are committed to providing the best possible care to pets diagnosed with cancer. Doctors will perform a systemic evaluation of your pet and decide on the best treatment plan, which may include chemotherapy, cryotherapy, immunotherapy, radiation therapy, surgery, or a combination of methods. Our goal is to provide you with a range of therapies to best meet your needs and the needs of your pet, and to do it with the utmost care and compassion.

Beginning in August 2017, an upgrade to our radiation oncology vault has enabled the addition of stereotactic radiosurgery (SRS) to the cancer care options available at SAGE’s Campbell location. This human-caliber radiation therapy unit is one of only a few in use across veterinary medicine.

Stereotactic Radiosurgery (SRS)

SAGE is proud to be one of a few specialty practices around the country offering stereotactic radiosurgery (SRS) for pets. We have partnered with PetCure Oncology to deliver these treatments, along with other more traditional forms of radiation therapy. SAGE will be the first veterinary hospital to deliver these treatments using Varian Medical Systems’ newest linear accelerator, the Halcyon Treatment System.

SRS is an advanced form of radiation therapy that has been a standard of care in human oncology for decades, but has just recently become available for pets. It is a non-invasive therapy that combines advanced treatment-planning technology with unprecedented precision to deliver maximum radiation dose directly to a tumor with minimal exposure to the surrounding healthy anatomy. (While the name has “surgery” in it, this refers to precise targeting of the tumor with radiotherapy; neither the patient nor the tumor undergoes surgery using this modality.)

An entire SRS treatment course is delivered in just 1 to 3 treatments, an 80-95% reduction in anesthetic sessions when compared to conventional radiation therapy. Because it is non-invasive and precise, SRS can be used to treat tumors in complex or delicate locations such as the brain, spine, or lungs. SAGE now has the ability to treat many tumors previously deemed a challenge to treat with standard radiation therapy.

Comprehensive Cancer Care Also Includes These Forms of Radiation Therapy

Conventionally Fractionated Radiation Therapy (CFRT)
Conventionally Fractionated Radiation Therapy (CFRT) uses targeted radiation to shrink or destroy cancers, including those that cannot be safely or completely removed by surgery alone. While SRS involves a fewer number of high-dose treatments, CFRT consists of multiple low-dose treatments spread out over a longer period of time. It can be used in conjunction with chemotherapy, following surgery, or as the sole treatment in cases where SRS is not an option. CFRT is typically administered daily in 16 to 20 treatment sessions over 3 to 4 weeks.

Palliative Radiation Therapy
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 or surgery, are not viable. Palliative treatments are typically delivered in 4 to 6 doses o f radiation given in a 1 to 4 week timeframe with the goal of relieving symptoms such as pain, bleeding, and decreased mobility.

Treatment of Feline Hyperthyroidism

SAGE Redwood City serves as home to Northern California’s only Radiocat Center for the Treatment of Feline Hyperthyroidism. Hyperthyroidism is a condition that causes behavioral changes, weight loss, excessive or decreased appetite, hyperactivity or lethargy, fever, rapid heartbeat and/or arrhythmia, shedding, increased water consumption and litter box output, diarrhea and osteoporosis. It can be fatal if left untreated. An alternative to medical and surgical treatments, Radiocat uses Iodine-131 injections to eliminate thyroid tumors.

Ongoing Research

SAGE oncologists are primarily focused on patient care, but also participate in clinical trials (designed to find new treatments for cancer), work in collaboration with veterinary schools for both teaching and research purposes, and are involved in education within our community of veterinarians and pet owners. SAGE doctors have kept abreast of the latest treatments to provide comprehensive and up-to-date options for your pet.

Our Oncology teams at each of our facilities are as follows:

Campbell – Dr. Michael Kiselow, Dr. Rebecca Regan and Dr. Steve Shaw.

Concord – Dr. Lori Cesario and Dr. Martin Crawford-Jakubiak.

Dublin – Dr. Wendi Velando Rankin and Dr. Chantal Tu.

Redwood City – Dr. Bryan Marker and Dr. Naoko Sogame.
