Hyperthermia and Immunotherapy in the Treatment of Cancer1:
The Gorter Model

I would cure all diseases if I only could produce fever.
Parmenides, Greek physician, 510 BC
Fever turns out to be one of the missing links in understanding cancer. A growing body of research
suggests that most cancer patients have a lower core temperature and cannot mount a fever, and thus
are unable to activate their immune system. In the clinical setting, these patients report having never
experienced a fever. The research provides strong evidence for this correlation.
Cancer and Fever
An extensive body of research suggests that many cancer patients have a lower core body temperature,
typically 0.8°F (0.5°C) lower than the average person. There may also be an inconsistent pattern in the
rhythm of their temperature over a 24-hour period (as shown in Figure 1).

In our clinical experience, many of these patients report that they often feel chilly or cold, with cold
hands and feet, and that this has been a typical pattern for the past several years. Documenting their
actual temperature, we find that their natural circadian rhythm for temperature is absent or disrupted.
Cancer patients also report that they were seldom ill before they developed cancer. They may
have experienced brief bouts of a sore throat, a cold, or a cough, but these illnesses were almost never
accompanied by a fever. These cancer patients, like most people in industrial societies, habitually use
aspirin, acetaminophen, or antibiotics at the first sign of a fever.

Fever as the source of immune activation. When body temperature reaches 101.3°F (38.5°C), typically
the immune system shifts into a state of intensive activity. At this temperature, immune factors in the
bloodstream increase two-fold or more, and in some cases as high as ten-fold, triggering an activation of
immune defenses throughout the body. Numerous studies have reported higher levels of messenger
chemicals, white blood cells, and immune scavengers in response to fever, reflecting a broad range of
immune factors:
Heat shock proteins2,3
Interleukins and other cytokines4
Human growth hormone5
Antigen-presenting dendritic cells6
Lymphocytes such as NK cells7,8and T-cells6, 9
Phagocytes such as macrophages10
Antibodies11
In vitro research at the University of Vienna found a ten-fold increase in monocytes when blood was
heated to 102.2°F (39°C).12 The researchers confirmed that this increase was associated with higher
levels of heat shock proteins in the bloodstream.
Fever: foe or friend? In our culture, there is a pervasive fear of fever, a tendency to see fever as the
cause of illness rather than the body’s natural mechanism for healing. While fever racks the patient, the
mother, father, friend, or caretaker stands by feeling powerless. No wonder it is a temptation to quickly
reach for medication such as aspirin or Tylenol™ at the first sign of a fever. The medicine represents
hope and recovery. Giving medication implies a cure. (And so does the advertising. The message is: If
you can just reduce the fever, the disease will go away.)
Ironically, the fear of fever is misplaced. Unless the fever is too high, above 104°F (40.0°C), or
persists for weeks at a time, no harm occurs. In fact, fever is the natural response of all mammals to
infection and illness. Research has made it clear that fever is not the enemy; it is the friend of healing.
This scientific rationale, supported by thousands of research studies, provides the basis for
hyperthermia treatment at the Medical Center Cologne and other medical centers in Europe and
worldwide.
Conditioning the fever response. Surprisingly, the immune system can be trained to turn on or off in
response to repeated cues—for example, in reaction to certain medications. This trained or
“conditioned” response was demonstrated in the work of Dr. Robert Ader and colleagues, published
over a period of more than 25 years.13,14,15,16 Researchers found that the immune system could actually
be deactivated through “classical conditioning.”
Applying this concept to the use of fever suppressing medications with children, the implication
is that over time the fever response can be permanently inactivated by the frequent use of these
medications. From that point on, whenever the child develops a fever, the fever process is aborted.
With frequent use of fever suppressants in childhood, the immune system may never become fully
2
activated and mature. The immune system is prevented opportunities for a “workout” and becomes less
and less adept, leaving the body more vulnerable.
Without an all-out effort by the immune system to completely wipe out an infection, bacterial
and viral infections can linger and become chronic. The association of chronic infection with cancer is
well documented for conditions that include human papilloma virus and cervical cancer, hepatitis and
liver cancer, and H. pylori bacteria and gastric cancer. These factors appear to set the stage for the
development of cancer.
Fever as the missing link in cancer. One of the most insightful looks at the role of fever in healing comes
from work published by the National Institutes of Health. Researchers performed an in-depth review of
the medical literature on cancer risk. They reported that risk appears to be increased in individuals who
have a history of fewer infections, noting “an inverse correlation between the incidence of infectious
diseases and cancer risk.”17 In sum, people who have not experienced common childhood illness and
fever apparently have a greater risk of cancer.
Averting fever with the frequent use of aspirin, acetaminophen, or antibiotics may actually
impair immune function. The research team concluded that “the occurrence of fever in childhood or
adulthood may protect against the later onset of malignant disease.”18,19 Researchers also pointed out
that “spontaneous remissions are often preceded by feverish infections.”18,19 Their final report on the
correlation between fever suppression and cancer includes more than 750 references from the medical
and research literature.20
A century of research on cancer and fever. A number of researchers have tracked this issue in large
clinical trials over the past 100 years, starting with published reports in 1854 that many cancer patients
exhibited a “remarkable disease-free history.”21 Several later studies confirmed this, reporting that
people who developed cancer were rarely ill before their disease.
Studies on the importance of fever as an immune defense against cancer were published in the
medical literature in 1854, 1910, 1934, and 1936, each study involving hundreds of patients.
Researchers consistently found increased cancer risk for patients who had no history of infectious illness
or fever.20 The majority of more recent studies have corroborated these findings.
German research published in 1983 found that cancer risk more than doubled in patients who
had not experienced major infectious diseases (2.6 times greater risk). Cancer risk was almost 6-fold
higher in patients who had never experienced the common cold (5.7 odds ratio), and there was a 15-fold
increase for those who had never experienced fever (15.1 odds ratio).22
A study of skin cancer patients, published in Melanoma Research in 1992, reviewed the medical
histories of 500 comparable patients, with and without cancer. Researchers found that the patients who
had experienced infections accompanied by fever had a much lower incidence of malignant
melanoma.23
3
Research published in the journal Cancer in 1992 evaluated the medical histories of more than
200 patients with brain tumors, who were compared with more than 400 similar noncancerous patients.
Those who had experienced infections and colds had a 70% lower risk of cancer.24
In a randomized control trial of 572 critically ill patients, published in 2005 in Surgical Infections,
82 patients with high fever were evaluated in further study. Half of these patients received aggressive
fever suppression, and the other half were advised to assume watchful waiting. There were seven
deaths in the aggressive group, and only one death in the watchful waiting group.25
In a recent study of 400 hospitalized pneumonia patients, the British Medical Journal reported
that the more feverish the patient on admission, the better their chance of 30-day survival. Of patients
admitted with a low core temperature, <96.8°F (36°C), the data show that 34% died; among those with
higher than normal core temperature, above 100.4°F (38°C), only 17% died within 30 days of
admission.26
These studies and hundreds of others demonstrate that fever suppression tends to inhibit the immune
response and healing. The research also suggests that when fever is tolerated by the patient through
careful watchful monitoring, frequently that improves outcome.
Heat Therapy and Hyperthermia
Fever and heat therapy have been recognized for their beneficial effects on health since antiquity.
Ancient Greek medicine, Roman sulfur hot baths, Finnish saunas, European and American spa
treatment, Japanese hot tubs, Native American sweat lodges, and therapeutic hot springs worldwide are
examples of simple forms of heat therapy as a means of cleansing and healing.
Limitations of traditional heat therapies. We know from systematic studies in the literature that
traditional methods such as saunas, mineral baths, and hot tubs do not significantly increase core
temperature, nor do they achieve temperatures that correspond to internally induced fever.
Consequently, a more innovative approach is necessary to raise the body to a therapeutic fever range.
This article will discuss contemporary innovations in hyperthermia, as applied in the treatment of
cancer.
A study at the Medical University of Hannover, Germany, found that when body temperature
was raised via warm baths, gradually heated to 107°F (42°C), core temperature actually increased less
than 1°F (0.4°C) above normal.32 Elevated body temperature alone does not automatically induce the
immune response, demonstrated in a study in Hamburg, Germany. The temperature of cancer patients
was increased with hyperthermia and compared with that of healthy volunteers who took part in
strenuous physical exercise to raise their temperature. Although participants in both groups experienced
elevated temperature, immune function increased in the cancer patients, but not in the healthy
volunteers. Elevated immune factors in cancer patients included human growth hormone and the
induction of natural killer cells and T-cells.30

Medical hyperthermia. Induced fever or hyperthermia has been studied in hundreds of cancer clinical
trials and discussed in thousands of peer-reviewed articles. Research on hyperthermia, also referred to
as “fever-range total-body hyperthermia” or “moderate whole-body hyperthermia,” has been
performed in medical schools and research centers since the 1980s. These studies have been conducted
primarily in the U.S., in Germany, across Europe, and in Japan. American research has been conducted in
FDA-approved studies at the Mayo Clinic, University of Pennsylvania, University of Texas, and Duke. The
medical literature reflects a global dialogue between researchers that has systematically defined
effective hyperthermia.
Safety and effectiveness. Hyperthermia has been studied for the treatment of chronic pain, recurrent
respiratory infections, asthma, urinary tract infections, and immune deficiency. Induced hyperthermia
was first evaluated in animal models 25 years ago, and then in human subjects over the past 20 years,
both in cancer patients and in healthy volunteers.27,28,29 Initial studies explored the most effective ways
to administer the therapy, defining the length of treatment,30 heat sources,31 optimal temperatures,32
and effects produced. Treatment has been applied as a freestanding therapy; in combination with
immune therapies such as dendritic cell injections;6 and in tandem with conventional therapies such as
radiation,33 chemotherapy,34 or hormone therapy.7 Two decades of research have shown that
hyperthermia is a safe procedure for the greater majority of patients and for many types of cancer.27,28
Treatment without side effects. Researchers at the Roswell Park Cancer Institute in Buffalo, New York,
report that total-body hyperthermia treatments are “well tolerated, with no significant adverse events
related to cardiac, hepatic, renal, or pulmonary systems.”29 A German study of hyperthermia for pain in
fibromyalgia patients tracked safety and effectiveness. “Side effects were observed in 14 of 69
participants (20%), but all disappeared in less than 30 minutes.”35 The study found that hyperthermia
combined with standard multimodal rehabilitation was significantly more effective than standard
therapy alone in terms of reducing pain intensity, while improving quality of life.
Hyperthermia and conventional treatment. Both whole-body hyperthermia and regional hyperthermia
increase the success rate of radiation33,36 and chemotherapy.34 This combination therapy often results in
fewer side effects than chemotherapy or radiation alone. A study conducted at a medical center in the
Netherlands tracked the progress of 378 cancer patients receiving hyperthermia in combination with
radiation treatments. Over an eight-year time period, a positive response was achieved in 77% of
patients. At five years, the disease-specific survival rate was 47%, which is exceptional in cancer
treatment. Toxicity was an issue for 12% of patients. Researchers concluded that in addition to
diagnosis, “the number of hyperthermia treatments emerged as a predictor of positive outcome.”35
Development of the Gorter Model
Hyperthermia is one of the primary approaches to treatment provided at the Medical Center Cologne.
The Center was founded by Robert Gorter, MD, PhD, and has been under his direction for the past 12
years. Immune supportive therapies are provided in a treatment model developed by Dr. Gorter. These
protocols have evolved from his understanding of immune function, garnered in his work as UCSF
5
program director of AIDS research and his background as a clinical oncologist, as well as from his
personal experiences as a cancer survivor himself.
Dr. Gorter earned his medical degree at the University of Amsterdam Medical School in the
Netherlands. He subsequently opened a private practice and health center in the heart of Amsterdam,
but a few weeks later he was diagnosed with far-advanced stage IV testicular cancer—at that time
described as “teratocarcinoma,” a type of cancer currently defined as “germ cell carcinoma.” He was
able to recover successfully through nontoxic treatment, without the use of chemotherapy or radiation.
His treatment consisted solely of hyperthermia and injections of a known oncologic botanical, European
mistletoe. This experience has motivated him to explore new, nontoxic approaches to cancer therapy
and has inspired his lifelong work as a researcher and clinician in the area of integrative cancer
oncology.
His exploration of immunotherapy deepened with his appointment as physician and researcher
on AIDS at San Francisco General Hospital in the world-renowned Ward 86 in the 1980s. When Ward 86
became part of the UCSF AIDS program, Dr. Gorter was appointed medical director of the Department of
AIDS Epidemiology and Biostatistics at UCSF, and led that department for four years. Much of what we
know today about the progression of HIV infection into AIDS comes from the seminal research on this
initial cohort of patients whose progress was tracked in long-term follow-up studies at UCSF. Dr. Gorter
was intrigued by the fact that a few of the patients with HIV infection never progressed to AIDS or AIDSRelated Complex (ARC), patients described as “long-term non-progressors.”
This work, conducted at the beginning of the AIDS epidemic in the U.S. and E.U., provided Dr.
Gorter the opportunity to be involved in the research and clinical care that first defined the complex
elements of the human immune system. These studies from UCSF Medical Center have resulted in the
most extensive knowledge base on immunity in HIV infection in our time. Dr. Gorter noticed that most
of the illnesses leading to the death of HIV-infected patients were malignancies. The resulting
deterioration of the immune system and of T-cell activity appeared to correlate with an increase in
various forms of cancer.
A decade later, when Dr. Gorter shifted the focus of his work to cancer treatment, he began
developing treatment protocols based on the principles of intensive and targeted immune restoration
learned in the “war on AIDS.” Dr. Gorter has spent more than two decades establishing and refining
effective methodology for immune therapy. He has pioneered the integrated use of hyperthermia to
reactivate the immune system, in combination with dendritic cell vaccination, which restores and
activates T-cells. These therapies are augmented with treatment using mistletoe botanicals, IV
antioxidants, and other immune restorative agents. Mistletoe, for example, is known to balance
biological rhythms in the body and helps to reestablish the fever response. Components of these
approaches to treatment have also been independently studied in hundreds of clinical trials conducted
at research centers worldwide.
Whole-Body Hyperthermia: Gorter Model
To date, the majority of the research on hyperthermia has been performed in Germany. At the Medical
Center Cologne, located in a large teaching hospital in Cologne, Germany, hyperthermia protocol
development has been ongoing under the direction of Dr. Gorter. Over the past 25 years, he has
6
carefully calibrated every aspect of these procedures for maximum safety and benefit. This model is
described in detail in the book Fighting Cancer: A Nontoxic Approach to Treatment.1
To reactivate immune function in cancer patients, the Gorter Model uses a controlled fever
process in which the entire body is gradually heated with infrared light to a moderate fever temperature
of 101°F to 103°F (38.5°C to 39.5°C) under carefully monitored conditions. These treatments engage the
patient’s immune system, replicating the natural process of fever, comparable to immune activation in
response to an acute infection.
Safety. This therapy is accomplished with almost no disruption or side effects—patients typically
experience less than one day of mild flulike symptoms. Once patients complete hyperthermia
treatment, they feel cleansed and energized. In many cases, this treatment is provided as the first stage
of the protocol to engage the immune system. The Gorter approach to whole-body hyperthermia is
distinguished by a number of features:
Moderate temperatures
State-of-the-science equipment
Heart rate monitoring at all times
An electrolyte IV solution throughout the procedure to maintain hydration
Safe, optimal infrared electro-hyperthermia technology developed by the German company Celsius
42
Dendritic cell injections at timed intervals, usually directly after hyperthermia
Integrative therapies in an individualized program
Protocol. The patient lies within a tentlike hyperthermia chamber with his or her head outside the
chamber. The body is heated by specially designed infrared lamps. (Infrared consists of invisible light
waves close to those of visible light on the spectrum and is the primary form of energy received from
the sun.) During hyperthermia, the infrared rays warm blood vessels close to the surface of the skin. As
the temperature in the skin rises, the temperature of blood in surface capillaries is elevated, circulation
increases, and the warmth spreads throughout the body.
With the increase in core temperature, the patient begins to perspire. However, in the closed
hyperthermia chamber, evaporation is reduced (as shown in Figures 2 and 3). Transpiration and
perspiration lead to cooling only when water can be evaporated. Without the process of evaporative
cooling, body temperature continues to increase, raising core temperature and inducing a feverlike
state. Once the temperature of 103°F (39.5°C) is achieved and maintained for one to two hours, the
fever is gradually reduced over the course of another hour or two.

Controlling temperature. This induced fever is maintained at a moderate temperature to safeguard the
well-being of the patient. Maximum temperatures range from 101°F to 103°F (38.5°C to 39.5°C). In
contrast to the Gorter Model, many of the research studies have used maximum temperatures of
approximately 107.5°F (41.8° to 42°C). In some studies, patients were anesthetized so they could
tolerate the high temperatures. Unnecessary anesthesia is always to be avoided, since it can induce
senility in older patients, a phenomenon known as Sundowner Syndrome. General anesthesia is also
frequently immune suppressive, and therefore should be minimized or avoided with cancer patients.
Contraindications. At the Medical Center Cologne, total-body hyperthermia is provided to
approximately 70% of all patients. Those with a history of heart disease or brain tumors must be
carefully screened. Because total-body hyperthermia can cause a certain amount of stress to the
system, it is usually not provided to patients with documented cardiac decompensation or those with
brain cancer because the therapy can potentially evoke cardiac difficulties or an epileptic seizure. For
almost all other patients, total-body hyperthermia has no known negative side effects.
Dendritic cell immunotherapy. Hyperthermia (like fever) activates Natural Killer cells (NK cells), which
play an important role in destroying malignant cells.37 To further engage the immune system, dendritic
cell therapy is provided to also activate T-cells.6
Dendritic cells are cultured in a medical laboratory from the patient’s own white blood cells
during the days preceding hyperthermia and are given by injection (as shown in Figure 4) directly
following the treatment. These dendritic cells have an antigen-presenting function—they hold in
“memory” the identity (antigen profile) of the malignant cells. A small injection conveys millions of vital,
activated dendritic cells, which then educate the patient’s own T-cells to search for and destroy
abnormal malignant cells. Acting in concert, the increased number of dendritic cells, activated T-cells,
and NK cells have inhibitory effects on tumor growth.38
8
After the injection, patients typically experience mild flulike symptoms for 6 to 12 hours. These
symptoms indicate the activation of the body’s healing response. Once the symptoms subside, almost all
patients report less pain than before the treatment, and a sense of well-being. It has been observed that
patients who react with flulike symptoms after the vaccination with dendritic cells clearly do better and
show more benefit from the therapy than those patients who do not experience this response. All
patients who achieved complete remission have experienced flulike symptoms.

permission from Gorter R, Peper E. Fighting Cancer.1
Once the immune system is engaged, the body begins destroying cancer cells from within. This reduces
the need for medication and stabilizes the body against further deterioration. These gains provide the
basis for a sense of well-being in the patient, and improve health and healing, even in many patients
with stage III and IV cancers. In a broad review of the literature by the authors, the majority of studies
reported a stabilizing therapeutic response in more than 50% of patients who received whole-body
hyperthermia—typically 56% to 80% of those treated.
Gorter treatment outcomes for breast cancer. The following outcomes data summarizes follow-up for
292 Medical Center Cologne patients with stage III and IV advanced metastatic breast cancer (patients
who had been advised that they had no further standard treatment options). Typical integrative
treatment for breast cancer includes whole-body hyperthermia, dendritic cell therapy, mistletoe, and
other types of immunotherapy, as well as improved diet and other lifestyle changes. All patients
received at least three cycles of dendritic cell therapy.

Case history: breast cancer. When I was diagnosed with malignancies for the fourth time, I decided to go
to Germany for treatment at the Cologne Medical Center. I had been diagnosed with breast cancer in
1999, and one of my breasts was surgically removed at that time, but I declined radiation or
chemotherapy. After careful thought, I decided to do a nontoxic follow-up treatment, but I also went
back to the hospital for periodic check-ups. For the next six years, I was in remission. But at that point, I
developed bone cancer. I beat it a second time, but the cancer came back again.
That is when I went to see Dr. Gorter. I improved very quickly with the treatment at Cologne—a
combination of hyperthermia and dendritic cell therapy. The pain disappeared very quickly and I was
soon pain-free. Walking had become difficult, because moving hurt so much. With this treatment, the
pain remains gone and I can walk again. Not all the tumors are gone. Bu the pain is gone and I feel good
about it. Iedje Abbenhuis, Belgium, five-year survivor of breast cancer with a previous history of
recurring bone and liver metastasis
Localized Hyperthermia: Gorter Model
To localize treatment for areas of the body such as the breast or brain, “regional” hyperthermia is
provided. This therapy can be used to selectively heat a specific area of the body, such as a tumor site.
Surrounding healthy cells are unaffected. At the Medical Center Cologne, this approach is used with
approximately 99% of patients.
Research. To date, there are more than 3000 articles in the medical literature listed under “regional
hyperthermia.” In conventional oncology, the majority of studies have evaluated local hyperthermia in
combination with chemotherapy or radiation. Over 330 clinical trials have been conducted in countries
worldwide, across Europe, and in Asia and Israel. Extensive research has been performed at the National
Cancer Research Center in Heidelberg, Germany, for more than two decades, and at the National Cancer
Institute in Rome. American studies include research at the Anderson Cancer Center in Houston, at
Duke, and at Wake Forest.
In a review by the authors of 50 recent clinical trials, 60% of the studies involved the use of
localized hyperthermia in combination with chemotherapy. The majority of the other studies evaluated
targeted hyperthermia with surgery or radiation. Other major studies assessed hyperthermia and
immunotherapy (primarily TNF- ) provided in tandem. Combining any of these therapies with localized
10
hyperthermia appears to increase effectiveness, with fewer side effects. However, only a handful of
large clinical trials have focused on localized hyperthermia as a stand-alone treatment, perhaps due to
the lack of economic incentives.
Mechanism. Tumor cells produce abnormal tumor-specific proteins, which are thousands of times larger
than normal proteins. During hyperthermia, these tumor proteins absorb energy when exposed to an
MRI-like electromagnetic field. This causes the malignant cells to heat up to an extremely high
temperature, 107.6°F (42°C). As a result of elevated temperatures, cancer cells increase their
metabolism and lactic acid production. As metabolism speeds up within tumor cells, they essentially
self-destruct and drown in the lactic acid they produce, resulting in cell death (necrosis). Localized high
temperature and the resulting death of cancerous cells simultaneously activate the immune system.
Neighboring healthy cells are unaffected and remain at normal body temperature.
Safety protocol. Electro-hyperthermia equipment used for localized hyperthermia in the Gorter Model
causes no risk of burns and can be focused exclusively on any area of the body. Tumor cells can be
heated selectively, because they have a much higher electromagnetic resistance than normal cells. This
makes possible interventions for areas of the body that would normally be difficult to treat, such as the
head, lungs, and bone tissue (see Figure 5).
Figure 5. Patient being treated with local hyperthermia for brain cancer (photo by Jan Asenbrennerova).

The fact that hyperthermia can be efficacious in treating brain tumors was borne out by a recent phase
III study for patients with brain lesions, in which hyperthermia proved to support significantly better
results in illness-free time and survival when compared with radiation and/or medication alone.
Localized heat treatment is provided in the Gorter Model to all patients who have solid tumors.
Integrative treatment. Localized hyperthermia is a highly effective means of destroying cancer cells
without causing toxicity, particularly when used in conjunction with other immune supportive therapies
such as vitamin C infusions, thymus peptides, and mistletoe extract. Most patients receiving localized
11
hyperthermia are provided with dendritic cell injections, since the heating process makes cancer cells
more vulnerable to destruction by the immune system.
Gorter treatment outcomes: brain cancer. At the Medical Center Cologne, even patients with primary
or secondary brain tumors or metastases of the breast or lung are successfully treated without any side
effects using this approach. The research shows that 44% of all patients with stage IV glioblastoma
multiforme go into complete, long-term remission, following a protocol of at least three dendritic cell
vaccinations and 24 sessions of local hyperthermia. This is a highly promising outcome, since with
conventional treatment approximately 72% of patients with brain tumors (glioblastoma multiforme
stage IV) die within the first year after diagnosis, and only 1% survive for three years.
Case history: brain cancer (recurrent glioblastoma multiforme stage IV). Twenty years ago, Teun van
Vliet was twice an indoor world champion cyclist and in 1988 wore the yellow jersey in the Tour de
France. In 2001 he was diagnosed with a brain tumor, and in 2006 an inoperable recurrence of the tumor
was detected. Teun had another round of brain surgery (“debulking”) and also received radiation
treatment. This caused him to lose his power of speech, and to some degree he also lost memory and
coordination. Within conventional oncology, nothing more could be done for him, and he was told that
he had less than six months left to live. Teun and his partner decided to seek a second opinion, and they
went to Cologne to consult with Dr. Gorter, who advised him to try localized hyperthermia in
combination with immune therapy. Teun’s partner soon reported beneficial changes in his health.
“The first thing we noticed about these treatments was that they really improved his speech. He
is much more lively; more active. I have my old buddy back, really. When he comes home from Cologne,
his speech has improved, his motor skills have improved, he feels more energetic. Nothing but
improvements. The quality of his life is definitely better.” Partner of Teun van Vliet, Tour de France
champion cyclist, patient at the Medical Center Cologne, and survivor of stage IV brain cancer. In April
2012, a new MRI scan confirmed that there was still no recurrence of the cancer, and Teun has been
clinically cancer-free for more than six years.
The Importance of an Integrative Approach
We believe that the noninvasive support provided by this protocol is an ideal adjunct to many treatment
programs, because it does not increase the level of toxicity in the body or the immune burden, nor is it
invasive. Hyperthermia can be provided in combination with a range of other therapies, both integrative
and conventional.
What makes this approach unique is the calibrated timing of hyperthermia and the dendritic cell
vaccinations, which are augmented with other elements of the program, such as IV antioxidants,
subcutaneous mistletoe injections, diet, and other lifestyle changes. The favorable outcomes indicate
that in this protocol, the sum of the whole is greater than the parts. This form of treatment does not
promise cure, but it does offer the possibility of improvement. The majority of stage IV patients
experience significantly longer survival with greater quality of life.
Several other elements contribute to the success of this therapy. The program tends to attract
patients who are proactive: they chose to seek help, and they have a will to live. In addition, Dr. Gorter
serves as a positive role model, because he is a cancer survivor. This provides a legitimate nonverbal cue
12
that hope is possible. Much of what he is suggesting to patients he has actually experienced and applied
in his own healing.
We predict that the next phase of this integrative approach will focus on patients at a much
earlier stage in disease progression. Given the low toxicity and the potential effectiveness of
immunotherapy, this treatment would be highly appropriate for patients who are advised to observe
watchful waiting.
