Encouraging news does not come often. This is why we are pleased to report
news of progress, help and hope in the battle against pediatric brain
stem gliomas. The welcome news comes from a dedicated research team at
the Falk Brain Tumor Center at Children's Memorial Hospital where a new
method of treatment has demonstrated positive clinical results.
Dr. Stewart Goldman, Medical Director of Neuro-Oncology, states, "With
the support of The Rory David Deutsch Foundation, we have developed
and are actively treating children with a novel regime. We are using the
medicine, Thalidomide with standard radiation and carboplatin chemotherapy
in an attempt to increase the survival rate for children suffering from
brain stem gliomas." So far, according to Dr. Goldman and study reports,
four of eleven (evaluable) child patients remain progression free. Cancer
has not progressed, which is definitely hopeful news, though Dr. Goldman
is quick to add cautions and emphasize the need for guarded optimism.
Caution about anything resembling a cure is understandable due to the
toughness of the disease and the low survival rate, which is less than
one year, for children with these tumors. Dr. Goldman points out that
many brilliant medical minds have been trying to unravel this enigma for
years, unfortunately with little success. No therapy to date has been
able to change the prognosis.
"We've been doing clinical trails," Goldman explains, "and
have been aggressive in our attempts to improve results, but our work
must also follow treatment standards we have established. Our therapies
must respect past outcomes, balance toxicity to potential benefits, minimize
the time children are in the clinic and hospital, assure ease of administration
and, above all, respect the child undergoing treatment. We want to do
everything in our power to cure these children, but with no assurance
as to outcome, we don't want the child to remain in the hospital for six
months. So it's a balancing act: balancing aggressive treatment while
also assuring quality of life."
A Combined
One, Two, Three Punch
As Goldman explains, the new therapeutic attack hits cancer on some powerful
fronts. First, is treatment with Thaliomide, an antiangiogenic agent that
prevents the formation of new blood vessel growth. Antiangiogenic agents
are an exciting class of new agents that break ground with traditional
therapies by preventing cancer cells from stimulating blood vessel growth
and thus getting the oxygen and nutrition they need to grow. "This
is great but not enough," adds Goldman. "Once you've got cancer
cells against the ropes, you've got to kill them, which is where standard
radiation and carboplatin chemotherapy come in. They are classic treatments
used to destroy cancer cells."
Another positive punch being added to the fight mix is the fact that,
based on the Falk Brain Tumor Center study, five or six other major institutions
have expressed interest and have indicated their desire to enroll patients.
According to Dr. Goldman, this adds more excitement to the prospect of
definitive trial numbers that will lend added credence to the positive
results to date. "We'd like to have 40 patients enrolled," he
says. He also notes that follow-up studies that are planned at the Falk
Center Clinic will further bolster results.
"Meanwhile, we'll take our four of eleven progression free children
as a very positive sign. We'll take the good news from this study even
though the data is very preliminary and add it to the next, and the next
after that. Then we'll need to add one more essential ingredient
a tincture of time, an infusion of waiting until we are sure."
