Radiation Oncology at Celilo Cancer Center
Radiation oncology is the medical use of ionizing radiation as part of
cancer treatment to control malignant cells. To spare normal tissues,
shaped radiation beams are aimed from several angles to intersect at the
tumor, providing a much larger dose there than in the surrounding, healthy tissue.
Celilo Cancer Center employs a radiation therapy technology called intensity
modulated radiation therapy (IMRT). Our Elekta Synergy linear accelerator
combines CT scanning with IMRT to help Celilo’s radiation specialists
even more precisely and effectively deliver the advanced IMRT technology.
The Synergy linear accelerator’s CT technology provides “3-D
image-guided” (IGRT) capabilities that enable higher doses of radiation
to be delivered more precisely to cancer tumors. This increases the daily
accuracy of treatment and reduces the effect on surrounding tissue. IGRT
allows staff to more efficiently and effectively adjust for the body and
organ movements that can occur during treatment
Brachytherapy
For many women diagnosed with breast cancer, radiation therapy is an effective,
and far less physically and emotionally taxing, alternative to mastectomy.
Several studies have shown that treatment combining tumor removal with
external radiation therapy has produced the same cure rate as total breast removal.
Yet, despite the obvious advantages of radiation treatment, many women
still choose to have mastectomies – often because of the long treatment
regimen required for external radiation treatment.
At Celilo, however, breast cancer patients may benefit from a procedure
called brachytherapy, which dramatically shortens the radiation therapy
process to only one week, compared with the four weeks required for external
radiation therapy. The procedure enables radiation specialists to deliver
higher doses of radiation to very defined areas of the breast without
affecting surrounding tissue.
Meet Sophia Bornstein, MD PHD
Dr. Sophia Bornstein is a board-certified radiation oncologist at Mid-Columbia
Medical Center’s Celilo Cancer Center.
As a board-certified radiation oncologist, Dr. Bornstein specializes in
the use of radiation therapy to reduce the symptoms of or cure cancer,
and in the overall care of patients with cancer. Dr. Bornstein has published
extensively on a number of radiological and oncological topics, and is
known for her research in head and neck cancers, and early phase clinical
trial development.
Dr. Bornstein earned her M.D. and Ph.D. at Oregon Health & Science
University, where she won multiple awards, scholarships and grants, including
the NIH the Pre-Doctoral Training Grant, Radiological Society of North
American Research Medical Student Grant and Tartar Trust Fellowship. She
completed her internship at Providence St. Vincent’s Medical Center
and took her residency at OHSU’s Department of Radiation Medicine,
where she started a resident-run palliative radiation program, taught
radiobiology and completed the American Board of Radiology Holman Research Pathway.
Prior to joining MCMC, Dr. Bornstein worked as a radiation oncologist in
a variety of settings, including as an assistant professor at OHSU, assistant
professor at Weill Cornell Medical College in New York and as a temporary
physician at multiple underserved communities throughout the country.
Dr. Bornstein feels honored to treat patients with cancer and counsel them
through treatment. She values relationships with her patients and their
families, and develops personalized treatment plans for her patients based
on their needs and wishes.
After 15 years in Portland, Dr. Bornstein is excited to transition to a
community treatment setting with a strong patient focus and impressive
provider expertise. In her free time, she enjoys hiking and wine tasting.
Meet Keith Stelzer, MD, PhD
Dr. Keith Stelzer is a leading expert in the application of intensity modulated
radiation therapy (IMRT) the technology used at Celilo that shapes radiation
beams more precisely to spare surrounding tissue.
Dr. Stelzer graduated from the University of California Davis in 1981.
He received his Ph.D. in toxicology from the University of Kansas Medical
Center in 1985 and his medical degree from the University of California,
Los Angeles, in 1989. Dr. Stelzer completed an internal medicine internship
at St. Vincent Hospital in Portland and a radiation oncology residency
at the University of Washington in Seattle, where he was chief resident
from 1992 to 1993.
Dr. Stelzer was associate professor in the Radiation Oncology and Neurological
Surgery departments at the University of Washington, and he continues
as a clinical associate professor of Radiation Oncology at UW Medical Center.
Board certified by the American Board of Radiology (Therapeutic), Dr. Stelzer
also is a member of the American Radium Society, the American Society
for Therapeutic Radiology and Oncology, and the North American Society
for Neuro-Oncology.
