Complementary
Therapies
Introduction
Complementary therapies refer to a diverse group of
medical practices and products that are not presently
considered a part of conventional medicine. Used as
a supplement to conventional treatments, limited research
suggests that many complementary therapies may be beneficial
to women with breast cancer by helping to manage symptoms
and improve quality of life. On the other hand, some
complementary therapies can interact negatively with
conventional cancer treatments or pose risks in and
of themselves. Informed guidance and supervision from
the patient's medical team are crucial for assuring
safe and appropriate use.
Complementary
vs. Alternative
Complementary therapy is used
as a supplement to conventional medicine, with
the intent of complementing conventional treatments. |
While complementary therapy is often mentioned together
with alternative therapy, there is a meaningful distinction
between the two terms. Alternative therapy is used
in place of conventional medicine whereas
complementary therapy is used as a supplement, with
the intent of complementing conventional
treatments.1 For
minor health issues, some alternative therapies may
not pose risks. However, in the case of breast cancer
or other serious illness, a reliance on alternative
therapy in place of conventional medicine is considered
by most health professionals as unwise. The preferred
approach combines the best of both traditions with
the full knowledge and involvement of the patient's
medical team. For women with breast cancer, certain
complementary approaches can be used to support the
efforts of conventional medicine before, during and
after treatment by helping to manage symptoms and improve
quality of life.
In recognition of the potential benefits complementary
therapies may have for cancer patients, many leading
medical centers offer integrative treatment programs
which combine conventional treatments, such as radiation
and chemotherapy, with certain complementary therapies,
such as acupuncture, massage,
aromatherapy, among others. For patients, these programs
allow for the safe use of unconventional therapies
under the direction of an informed medical team. For
health professionals, integrative programs promote
ongoing professional growth in a setting where unconventional
and conventional treatments can be examined together.
The recent growth of integrative programs in the U.S.
is partly attributed to the sheer popularity of use
among consumers.2

Use of Complementary
and Alternative Medicine (CAM) in the U.S.
According to the National Center for Alternative and
Complementary Medicine (NCCAM), the U.S. public spent
an estimated $36 to $47 billion on CAM therapies in
1997. Of this, between $12 and $20 billion was paid
out-of-pocket for the services of CAM practitioners,
more than the public paid out-of-pocket for all hospitalizations
and about half of what it paid for all out-of-pocket
physician services during that same year. Five billion
dollars of out-of-pocket spending was on herbal products.3
More recent findings about CAM use derive from the
2002 edition of the National Health Interview Survey,
conducted by the National Center for Health Statistics
(NCHS).4 According
to this survey, 36% of U.S. adults use some form of
CAM. When megavitamin therapy and prayer used
specifically for health reasons were included in the
definition, the percentage rose to 62%. Of the survey
respondents that reported using CAM, over a quarter
indicated that a conventional medical professional
suggested trying CAM. Over half believed that CAM would
improve their health when used in combination with
conventional medical treatments.
 |
As the use of CAM gains popularity among U.S. health
consumers, it is in the best interest of patients for
their practitioners of conventional medicine to keep
an open mind while evaluating these different approaches.
The danger of doing otherwise is that the patient interested
in unconventional treatment may seek help elsewhere
at the exclusion of essential medical care. Similarly,
if a patient feels uncomfortable disclosing her use
of CAM to her doctor, the risk of treatment interference
from certain herbs or dietary supplements is increased.
Healthcare providers are encouraged to ask patients
about their use of CAM, and to share with them their
medical opinions through open and respectful dialogue.

Types of
CAM
In contrast to conventional medicine, the orientation
of CAM is holistic: it seeks to address the physical,
mental, emotional and spiritual needs of the whole
person. As such, treatment programs are often highly
individualized, utilizing various types of practices
and products drawn from the five major CAM types. These
types, also called domains, are briefly described as
follows:
Whole Medical Systems are
built upon complete systems of theory and practice
that have evolved independent of conventional medicine
used in the U.S. Major Eastern whole medical systems
include traditional Chinese medicine (TCM) and Ayurvedic
medicine, from India. Major Western whole medical systems
include homeopathy and naturopathy. Other systems have
been developed by Native American, African, Middle
Eastern, Tibetan, and Central and South American cultures.
Mind-Body Interventions use
a wide variety of techniques designed to enhance the
mind's ability to affect the body's function and symptoms.
Examples include such various approaches as meditation,
hypnosis, biofeedback, yoga, guided imagery, breathing
techniques, and prayer. Therapies that use creative
outlets such as art, music or dance are also included
within this domain. Some mind-body techniques previously
considered CAM have become adopted into the mainstream,
such as patient support groups and cognitive-behavioral
therapy.
Biologically Based Therapies make
use of substances found in nature, such as botanicals,
animal-derived extracts, vitamins, minerals, fatty
and amino acids, proteins, prebiotics and probiotics,
whole diets, and functional foods. Dietary supplements
are a subset of this type of CAM.
Manipulative and Body-Based Methods are
therapies that work with one or more parts of the body.
Some examples in this heterogeneous group include chiropractic
and osteopathic manipulation, massage therapy, Tui
Na, reflexology, rolfing, Bowen technique, Trager bodywork,
Alexander technique, Feldenkrais method, and many others.
Some derive from ancient systems of medicine while
others were developed within the last 150 years (e.g.,
chiropractic and osteopathic manipulation).
Energy Therapies are based
on a core belief in the existence of a universal life
force, or subtle energy, that resides in and around
the body. There are of two main types of energy
therapies, known as veritable (which can be measured)
and, putative (which have yet to be measured). Bioelectromagnetic-based
therapy (a veritable form) involves the unconventional
use of electromagnetic fields, such as pulsed fields,
magnetic fields, or alternating-current or direct-current
fields. Biofield therapy (putative form) is intended
to affect energy fields that purportedly surround and
penetrate the body. Examples include qi gong, Reiki,
Therapeutic Touch, and intercessory prayer, in which
a person intercedes through prayer on behalf of another.

Safety
and Efficacy
Conventional cancer treatments have
been rigorously studied for their safety and efficacy
through high-quality scientific research. In contrast,
only a relatively small proportion of therapies currently
considered CAM have been well-researched. As a result,
many key questions about safety and efficacy remain
unanswered.
Therapies such as acupuncture, biofeedback, and meditation
are generally considered safe and effective for helping
cancer patients relieve pain, ease side effects, and
enhance their quality of life. Additional complementary
methods that the American Cancer Society (ACS)
list as potentially helpful for some people, when used
along with standard medical treatment, are aromatherapy,
yoga, tai chi, music therapy, art therapy, prayer and
spirituality.5 Other
therapies, however, including certain herbs and dietary
supplements, can cause harm by interfering
with conventional
treatments. For example, ginkgo biloba, garlic, vitamin
E, and ginger when taken alone can help to prevent
abnormal blood clotting but, if taken with chemotherapy,
there may be abnormal bleeding. Likewise, some types
of supplements may dangerously interact with anesthesia
for patients having surgery, or cause skin reactions
for patients being treated with radiation therapy.6 Some
dietary supplements and herbs can also have negative,
even dangerous, effects on their own, as may certain
body manipulation techniques. While limited research
suggests that many types of complementary therapies
may be beneficial to women with breast cancer when
used in a supportive role, informed guidance and supervision
from the patient's primary care provider are crucial
for assuring safe and appropriate use.
For comprehensive fact sheets on herbs and supplements,
including information about dosing, interactions and
safety, visit Medline
Plus, a service of the U.S. National Library of
Medicine and National Institutes of Health. Similar
safety and efficacy issues about CAM techniques can
be researched at InteliHealth,
an Aetna-sponsored web site featuring content created
by faculty at Harvard Medical School.
The same scientific evaluation
used to assess conventional cancer treatments
should be used to assess CAM therapies. |
NCCAM, the federal government's lead agency for the
scientific study of complementary and alternative medicine,
maintains that the same scientific evaluation used
to assess conventional cancer treatments should be
used to assess CAM therapies. Recent NCCAM trials include
studies of acupuncture (to relieve neck and shoulder
pain following surgery for head or neck cancer); massage
(for the treatment of cancer pain); ginger (as a treatment
for nausea and vomiting caused by chemotherapy); and
mistletoe extract combined with chemotherapy (for the
treatment of solid tumors). Additional NCCAM trials
are ongoing, some conducted in partnership with other
institutes at the National Institutes of Health (NIH).

Clinical Trials web page.

Finding
a Provider
Assuming that a patient's choice of CAM is medically
appropriate, her primary care provider can assist
with the process of finding a qualified CAM practitioner.
Provider involvement will help ensure coordinated
care and increase the chances of a positive outcome.
NCCAM suggests calls to local hospitals or medical
schools for a list of area CAM practitioners. Contacting
representative professional organizations is also
recommended for inquiring about standards of practice,
training needed, and whether or not licensing or
certification by an approving state authority is
required. The National Library of Medicine provides
a comprehensive Online directory of health organizations
at DIRLINE.
If licensing laws do not apply for a particular CAM
therapy, asking about a practitioner's length of
training and experience is basic. Additional guidance
for finding a qualified CAM provider can be found
in NCCAM's Online publication: Selecting
a CAM Practitioner.
Once a potential CAM provider has been found, the
National Cancer Institute recommends the following
sets of questions:7
General questions for the CAM practitioner:
-
What types of CAM do you practice?
-
What are your training and qualifications?
-
Do you see other patients with
my type of cancer?
-
Will you work with my doctor?
Questions about the therapy for the
CAM practitioner:
-
How can this help me?
-
Do you know of studies that prove
it helps?
-
What are the risks and side effects?
-
Will this interfere with my cancer
treatment?
-
How long will I be on the therapy?
-
What will it cost?
-
Do you have information that I
can read about it?
-
Are there any reasons why I should
not use it?
Questions for a patient to ask herself:
-
Do I feel comfortable with this
person?
-
Do I like how the office looks
and feels?
-
Do I like the staff?
-
Does this person support standard
cancer treatments?
-
How far am I willing to travel
for treatment?
-
Is it easy to get an appointment?
-
Are the hours good for me?
-
Will insurance cover the cost of
CAM?

Evaluating
CAM Information on the Internet
Enter the terms "complementary and alternative
medicine" into the search feature at Google.com
and it will respond with over 2 million listings.
Many of these web pages provide valuable and valid
information. Others, however, may not. Knowing how
to tell the difference is essential when seeking
information about unconventional therapies.
Patients who find CAM-related content on the Internet
should be encouraged to discuss what they find with
their doctors, taking special note of the information
source. Who runs the site? Who funds the site?
What is its purpose? Generally, web sites sponsored
by federal and state governments, along with university
medical schools, are among the best for finding accurate
and balanced content, but these are not the only
reliable sources, nor is source the only important
indicator. Where does the information come
from? How is it selected? Is the information current?
These are also important questions. If a web site
links to other web sites, to which does it link?
The same set of questions should be applied to the
web site's list of selected links. How the web site
manages interactions with visitors is also key. Does
it specify its terms of use and privacy policy? Does
it provide a way for visitors to contact owners with
problems and feedback? Does someone respond? With
regard to CAM, web sites that permit Online purchasing,
post patient testimonials, or claim a cure for cancer
should raise red flags.
The U.S. Food and Drug Administration (FDA) has
prepared a quick summary checklist of the most important
questions to ask:8
-
Can you easily see who sponsors
the web site?
-
Is the sponsor a government agency,
a medical school, or a reliable health-related
organization, or is it related to one of these?
-
Is there contact information?
-
Is your privacy protected?
-
Does the web site make claims that
seem too good to be true? Are quick, miraculous
cures promised?
More information can be found by reading the entire
FDA publication, How
To Evaluate Health Information on the Internet or
from NCCAM's 10
Things To Know About Evaluating Medical Resources on
the Web. Moore's University of California,
San Diego Cancer Center has also prepared an excellent
guide for Evaluating
and Interpreting Information on the Internet.
In addition to these, quackwatch.org is
a nonprofit corporation "whose purpose is to
combat health-related frauds, myths, fads, and fallacies." Founded
and maintained by a medical doctor, with assistance
from a worldwide network of volunteers and expert
advisors, quackwatch.org is an indispensable resource
for helping providers and their patients assess the
reliability of web sites proffering CAM information.
Finally, providers can recommend that their patients
look for the HONcode seal on health and medical web
sites. Health
On the Net Foundation (HON) is a non-profit,
non-governmental organization dedicated to "promoting
and guiding the deployment of useful and reliable
Online medical and health information, and its appropriate
and efficient use." The HONcode seal appearing
on health-related Web sites identifies compliance
with a set of basic ethical standards.
