What if you could treat cancer without surgery, without chemotherapy and without ionizing radiation? What if you could extend a dying patient's
life by years without any side effects? And if the patient were in pain, you could get rid of that too? All that may be possible sooner than you think.
American and Brazilian cancer researchers have succeeded in stabilizing and shrinking inoperable liver tumors with
radiofrequency (RF) radiation that is no more powerful than that emitted by a typical cell phone.
This is "exciting" news, said Boris Pasche of the University of Alabama
medical school in Birmingham.
Frederico Costa of the University of São Paulo medical school, Pasche's collaborator, agrees.
"We observed significant tumor shrinkage in 10% of patients," he wrote in an e-mail to Microwave News. Costa points out that this is five times the
success rate of the best available chemotherapeutic drug —Sorafenib
—and that "there are essentially no side effects."
Costa and Pasche's new findings were published by the British Journal of Cancer last week.
(The paper is open access.) Costa is the director
of clinical research at the Brazilian Institute for Research on Cancer in São Paulo. Pasche is the director of the
Division of Hematology and Oncology at the University of Alabama School of Medicine.
Liver cancer is a massive public health problem. It is the second most frequent cause of cancer mortality among men worldwide; for women, it is the sixth leading
cause of cancer death. In 2008, there were approximately 750,000 new cases and close to 700,00 deaths around the world; half of these were in
China, according to the most recent statistics.
Not only could this new therapy, called TheraBionic, revolutionize the treatment of liver cancer, it might also stimulate new respect for
electromagnetic medicine, as well as prompt a major reevaluation of electromagnetic health risks, most especially with respect to the
safety of cell phones.
An Otherwise Poor Prognosis
Patients with liver tumors, hepatocellular carcinoma (HCC)
that cannot be completely removed during surgery have a very poor prognosis. Their average survival time is just three to six months. While the
median overall survival of the 41 patients in Costa and Pasche's treatment group was only somewhat longer (6.7 months), eight of their patients had a remarkable response.
Six of the eight went on to live for more than two years —four of them for at least three years. Notably, five of the six long-term survivors had tumors that were actively growing when they
began receiving RF therapy. One of these five, a 76-year old woman, was still alive and being treated close to five years later.
Four (9.8%) of Costa and Pasche's 41 patients with terminal liver cancer saw the size of their tumors decrease by at least 30%. By comparison,
in a similar trial using the drug Sorafenib, only 3 of 137 patients (2%)
showed the same level of tumor response.
In all, eight of the patients receiving RF therapy either saw their tumors shrink or they survived for longer than two years, or both.
The RF therapy also helped many of the patients who were in pain. Of the 11 patients reporting pain before entering the trial, five said
that it completely disappeared and two said that it decreased soon after treatment began. There was no change for two others; two
complained that there was more pain after treatment.
One clear inference from the trial is that some patients were much more responsive to RF therapy than others. The reasons why are unknown. Pasche explained that
all sorts of different people fared better, without any obvious traits in common. "Both men and women, Caucasian and non-Caucasian,
patients with hepatitis B, hepatitis C or no hepatitis infection responded to the therapy," he said.
Even though Pasche and Costa don't have a mechanism in hand to explain how the radiation can control the growth of the tumors,
they state that their "novel therapeutic approach does not depend on temperature changes within the tumor."
