Revolutionary Cancer Treatment
Tragically 50 percent of women who have
breast cancer will also suffer metastatic cancer that
has spread to other areas, such as the liver, lungs,
bones and brain. Fortunately, a treatment called body
radiosurgery can provide an alternative to the limitations
of chemotherapy.
Body radiosurgery utilizes multiple, finely contoured
beams of radiation from many different angles to attack
the cancer. This outpatient procedure is virtually painless
and allows patients to return to normal activities quickly
and with minimal side effects. Results have been encouraging.
More than 85 percent of patients experienced positive
control rates in which the cancer disappeared completely
or the tumor stopped growing or shrank. The technique
was pioneered in the early 1990s at the Karolinska Institute
in Sweden and has been used in more than 1,000 treatments
worldwide.
Typically it requires only three to five 45-minute treatment
sessions, as opposed to potentially years of chemotherapy,
said Robert A. Behar, medical director at the Spring
Branch Radiation Oncology Center in Houston, a freestanding
facility on the campus of Spring Branch Medical Center.
"Body radiosurgery is a tremendous development
for women who have exhausted chemotherapy and may be
facing terminal conditions," said Dr. Behar, one
of four physicians in the United States to have obtained
special training at Karolinska.
Dr. Behar and his medical team use state-of-the-art
computers and technology to create their body radiosurgery
treatment plans. After an initial consultation, the
patient visits the Spring Branch Radiation Oncology
Center and is situated in an immobilizing body frame
linked to a modern three-dimensional treatment planning
computer. Then, the patient and frame are positioned
in a computerized tomography scanner where the exact
size and location of the tumor are assessed. To verify
the plan, a second visit and simulation are conducted,
after which actual treatment is scheduled.
"Because the procedure in noninvasive," said
Dr. Behar, "the patients needs little preparation
and can eat prior to treatment. No blood is drawn, and
the patient is not radioactive." He added that
even patients who have been told there is no further
treatment available may be candidates for body radiosurgery.
More than thirty percent of our body radiosurgery patients
fit this category and have successfully completed this
treatment program."
