Today is WORLD CANCER DAY.
Yesterday I prepared you for this event by alerting you to a disgusting cancer scam, and today I want to contrast this with more encouraging news from the strange world of alternative medicine. So I searched Medline for a fitting, recent publication showing at least some value of an alternative therapy. Believe me, such papers are few and far between.
But here is one:
The aim of this Cochrane review was to assess effects of yoga on health-related quality of life, mental health and cancer-related symptoms among women with a diagnosis of breast cancer who are receiving active treatment or have completed treatment. The authors conducted extensive literature searches and applied no language restrictions. RCTs were eligible, if they (1) compared yoga interventions to no therapy or to any other active therapy in women with a diagnosis of breast cancer, and (2) assessed at least one of the primary outcomes on patient-reported instruments, including health-related quality of life, depression, anxiety, fatigue or sleep disturbances.
Two review authors independently collected data on methods and results. The risk of publication bias was assessed through visual analysis of funnel plot symmetry and heterogeneity between studies. Subgroup analyses were conducted for current treatment status, time since diagnosis, stage of cancer and type of yoga intervention.
Twenty-four studies with a total of 2166 participants were included, 23 of which provided data for meta-analysis. Thirteen studies had low risk of selection bias, five studies reported adequate blinding of outcome assessment and 15 studies had low risk of attrition bias. Seventeen studies that compared yoga versus no therapy provided moderate-quality evidence showing that yoga improved health-related quality of life, reduced fatigue and reduced sleep disturbances in the short term. There was an overall low risk of publication bias.
Yoga did not appear to reduce depression or anxiety in the short term and had no medium-term effects on health-related quality of life or fatigue. Four studies that compared yoga versus psychosocial/educational interventions provided moderate-quality evidence indicating that yoga can reduce depression, anxiety and fatigue in the short term. Very low-quality evidence showed no short-term effects on health-related quality of life or sleep disturbances. Three studies that compared yoga to exercise presented very low-quality evidence showing no short-term effects on health-related quality of life or fatigue. No trial provided safety-related data.
The authors concluded that moderate-quality evidence supports the recommendation of yoga as a supportive intervention for improving health-related quality of life and reducing fatigue and sleep disturbances when compared with no therapy, as well as for reducing depression, anxiety and fatigue, when compared with psychosocial/educational interventions. Very low-quality evidence suggests that yoga might be as effective as other exercise interventions and might be used as an alternative to other exercise programmes.
As I said, this is most encouraging. Many women are attracted by yoga, and the news that it can improve their symptoms is clearly positive. I have said it often, but I say it again: in supportive and palliative cancer care there might be an important role for several forms of CAM. One has to make sure though that they do not interfere with conventional treatments, and – this is very important – cancer patients must not be misled to believe that they can be used to treat or cure cancer. Finally, patients should not pitch their hopes too high: the effect sizes of alternative treatments in cancer care are invariably small or modest which means that they can help to reduce symptoms but are unlikely to get rid of them completely.
On an even more sober note, I have to reiterate that none of the trials included in the above review reported safety data (yoga is not totally devoid of adverse-effects!). This is an almost stereotypical finding when assessing clinical trials of alternative therapies. It discloses a clear and unacceptable breach of publication ethics. How can we ever get a realistic impression of the risks of alternative medicine, if adverse effects remain unreported? It is high time that researchers, authors, journal editors and reviewers get this message and behave accordingly.
Tomorrow is WORLD CANCER DAY. To mark this important occasion, I intend to publish not just one but two posts. Today’s post discloses one of the more sickening alternative cancer scams I have seen for a long time (tomorrow’s post will be a lot more encouraging): baking soda as a cancer cure. Here is what some charlatans tell the most vulnerable of our patients.
START OF QUOTE
Even the most aggressive cancers which have metastasized have been reversed with baking soda cancer treatments… Doctors and pharmaceutical companies make money from it. That’s the only reason chemotherapy is still used. Not because it’s effective, decreases morbidity, mortality or diminishes any specific cancer rates. In fact, it does the opposite. Chemotherapy boosts cancer growth and long-term mortality rates and oncologists know it…
Studies have shown that dietary measures to boost bicarbonate levels can increase the pH of acidic tumors without upsetting the pH of the blood and healthy tissues. Animal models of human breast cancer show that oral sodium bicarbonate does indeed make tumors more alkaline and inhibit metastasis. Based on these studies, plus the fact that baking soda is safe and well tolerated, world renowned doctors such as Dr. Julian Whitaker have adopted successful cancer treatment protocols as part of an overall nutritional and immune support program for patients who are dealing with the disease…
When taken orally with water, especially water with high magnesium content, and when used transdermally in medicinal baths, sodium bicarbonate becomes a first-line medicinal for the treatment of cancer, and also kidney disease, diabetes, influenza and even the common cold. It is also a powerful buffer against radiation exposure, so everyone should be up to speed on its use. Everybody’s physiology is under heavy nuclear attack from strong radioactive winds that are circling the northern hemisphere…
The pH of our tissues and body fluids is crucial and central because it affects and mirrors the state of our health or our inner cleanliness. The closer the pH is to 7.35-7.45, the higher our level of health and wellbeing. Staying within this range dramatically increases our ability to resist acute illnesses like colds and flues as well as the onset of cancer and other diseases. Keeping our pH within a healthy range also involves necessary lifestyle and dietary changes that will protect us over the long term while the use of sodium bicarbonate gives us a jump-start toward increased alkalinity…
Basically, malignant tumors represent masses of rapidly growing cells. The rapid rate of growth experienced by these cells means that cellular metabolism also proceeds at very high rates. Therefore, cancer cells are using a lot more carbohydrates and sugars to generate energy in the form of ATP (adenosine triphosphate). However, some of the compounds formed from the energy production include lactic acid and pyruvic acid. Under normal circumstances, these compounds are cleared and utilized as soon as they are produced. But cancer cells are experiencing metabolism at a much faster rate. Therefore, these organic acid accumulate in the immediate environment of the tumor. The high level of extracellular acidity around the tumor is one of the chief driving force behind the metastasis of cancer tumors. Basically, cancer cells need an acidic environment to grow and spread rapidly…
One does not have to be a doctor to practice pH medicine. Every practitioner of the healing arts and every mother and father needs to understand how to use sodium bicarbonate. Bicarbonate deficiency is a real problem that deepens with age so it really does pay to understand and appreciate what baking soda is all about.

I am sure you agree: this is not just unethical and irresponsible; it is vile!
There are far too many falsehoods in this text (and most of them are too obvious) for me to even begin to correct them.
Why do I post this just before WORLD CANCER DAY?
Because I believe that cancer patients need to be protected from people and institutions who tout dangerous nonsense. Sadly, in the realm of alternative medicine, there are many of such charlatans.
You probably guessed: this is the headline of a new WDDTY article. WDDTY tell us that they provide “information on complimentary therapies and alternative medicines” (I don’t want to sound snobbish, but I have my doubts about people who don’t even know how to spell their subject area). As the actual article in question (on vitamin C for cancer, a subject we have discussed on this blog before here and here) is quite short, I might as well show you its full beauty:
START OF QUOTE
High-dose vitamin C does kill cancer—but only when it’s given intravenously. It’s now just a few steps away from being approved as a safe and effective cancer treatment alongside chemotherapy and radiation.
Although researchers have tested the vitamin as a cancer therapy many times, they almost always concluded that it was ineffective—but they were guaranteeing failure by giving it orally to patients.
When it’s given intravenously, it bypasses the gut and goes directly into the bloodstream—where concentrations of the vitamin are up to 500 times higher than when it’s taken orally—and targets cancer cells, say researchers at the University of Iowa.
The therapy is now going through the approval process, and could soon be available as an alternative to chemotherapy or radiation, the two conventional cancer treatments.
It’s been proved to be effective in animal studies, and phase 1 trials have demonstrated that it’s safe and well-tolerated.
Now doctors at the university are starting to use it on patients with pancreatic cancer and lung cancer, and are measuring their progress against other patients who will continue to be given chemotherapy or radiation.
Biologist Garry Buettner, who works at the university, has worked out just why vitamin C is so effective: the vitamin breaks down quickly in the body, and generates hydrogen peroxide that kills cancer cells. “Cancer cells are much less efficient in removing hydrogen peroxide than normal cells, so cancer cells are much more prone to damage and death from a high amount of hydrogen peroxide”, he explained. “This explains how very, very high levels of vitamin C do not affect normal tissue, but can be damaging to tumour tissue.”

According to the author, these amazing claims are based on one single source: a Medline-listed article with the following abstract:
Ascorbate (AscH–) functions as a versatile reducing agent. At pharmacological doses (P-AscH–; [plasma AscH–] ≥≈20mM), achievable through intravenous delivery, oxidation of P-AscH– can produce a high flux of H2O2 in tumors. Catalase is the major enzyme for detoxifying high concentrations of H2O2. We hypothesize that sensitivity of tumor cells to P-AscH– compared to normal cells is due to their lower capacity to metabolize H2O2. Rate constants for removal of H2O2 (kcell) and catalase activities were determined for 15 tumor and 10 normal cell lines of various tissue types. A differential in the capacity of cells to remove H2O2 was revealed, with the average kcell for normal cells being twice that of tumor cells. The ED50 (50% clonogenic survival) of P-AscH– correlated directly with kcell and catalase activity. Catalase activity could present a promising indicator of which tumors may respond to P-AscH–.
The author of the WDDTY article is Bryan Hubbard. I did not know this man but soon learnt that he is actually the co-founder of WDDTY. He may not know how to spell ‘complementary medicine’ but he certainly has a lot of fantasy! His latest drivel on vitamin C for cancer seems to prove it. He seems to have the ability to extrapolate from the truth to a point where it becomes unrecognisable. The claims he makes in his article in question certainly are in no way supported by the evidence he provided as his source.
This could be trivial; yet sadly, it isn’t: WDDTY is read by many members of the unsuspecting public. Some of them might have cancer or know someone who has cancer. These desperate patients are likely to believe what is published in WDDTY and might be tempted to act upon it. In other words, the totally misleading articles by Hubbard put lives at risk – and that I cannot find trivial!
What doctors don’t tell you is not what WDDTY suggest; doctors don’t tell you that vitamin C reverses cancer because it is not true. In view of this and other evidence, perhaps the acronym WDDTY is not the best for this publication? Could I perhaps suggest to ‘Hubbard and Co’ another abbreviation? How about MIFUC (MisInformation From Unethical Columnists)?[yes, I know, I was tempted to chose another noun for the ‘C’, but I resisted!]
Yesterday I received an electronic Christmas card from two homeopathic institutions called ‘Homeopathic Associates and The Homeopathic College’. It read: WISHING YOU THE BEST OF HEALTH AND HAPPINESS FOR THE NEW YEAR!
Naturally I was puzzled, particularly since I had no recollection of ever having been in contact with them. The card was signed by Manfred Mueller, MA, DHM, RSHom(NA), CCH, and I decided to find out more about this man. It turns out that Manfred Mueller developed The Mueller Method or “Extra-Strength Homeopathy” to meet today’s complex chronic conditions, drug induced disorders, vaccine injuries, toxic overload, radiation-induced health problems, cancers, etc.
Now, this sounds interesting, I thought, and read on. Just a few clicks further, Mueller offers his wisdom on homeopathic cancer treatments in a lengthy article entitled ‘Is Homeopathy an Effective Cancer Treatment?‘
According to Mueller, the answer to his question is a clear yes. I will spare you the torture of reading the entire paper (if you have masochistic tendencies, you can read it via the link I provided above); instead, I will just copy Mueller’s conclusion:
START OF QUAOTE
Laboratory studies in vitro and in vivo show that homeopathic drugs, in addition to having the capacity to reduce the size of tumors and to induce apoptosis, can induce protective and restorative effects. Additionally homeopathic treatment has shown effects when used as a complementary therapy for the effects of conventional cancer treatment. This confirms observations from our own clinical experience as well as that of others that when suitable remedies are selected according to individual indications as well as according to pathology and to cell-line indications and administered in the appropriate doses according to the standard principles of homeopathic posology, homeopathic treatment of cancer can be a highly effective therapy for all kinds of cancers and leukemia as well as for the harmful side effects of conventional treatment. More research is needed to corroborate these clinical observations.
Homeopathy over almost two decades of its existence has developed more than four hundred remedies for cancer treatment. Only a small fraction have been subjected to scientific study so far. More homeopathic remedies need to be studied to establish if they have any significant action in cancer. Undoubtedly the next big step in homeopathic cancer research must be multiple comprehensive double-blinded, placebo-controlled, randomized clinical trials. To assess the effect of homeopathic treatment in clinical settings, volunteer adult patients who prefer to try homeopathic treatment instead of conventional therapy could be recruited, especially in cases for which no conventional therapy has been shown to be effective.
Many of the researchers conducting studies — cited here but not discussed — on the growing interest in homeopathic cancer treatment have observed that patients are driving the demand for access to homeopathic and other alternative modes of cancer treatment. So long as existing cancer treatment is fraught with danger and low efficacy, it is urgent that the research on and the provision of quality homeopathic cancer treatment be made available for those who wish to try it.

Amazing! What could be more wrong than this?
But it’s the season of joy and love; so, let’s not go into the embarrassing details of this article. Instead, I feel like returning the curtesy of Mr Mueller’s Christmas card. Therefore, I have decided to post this open ‘Christmas card’ to him:
Dear Mr Mueller,
thank you for your card, the good wishes, and the links you provided to your websites, articles, etc. I only read the one on cancer but was impressed. It is remarkably misguided, unethical and dangerous. Crucially, it has the potential to shorten the lives of many desperate patients. I therefore urge you to desist making your opinions public or from applying them in your clinical practice. I say this not merely because I am concerned about the patients that have the misfortune to fall into your hands, but also to prevent you from getting into trouble for immoral, unethical or unlawful behaviour.
In this spirit, I wish you happiness for the New Year.
The Scotsman reported that David Tredinnick, the somewhat feeble-minded Tory MP for Bosworth, has been at it again. Apparently he said that many of his constituents are only alive today because they have been treated with alternative medicine.
Tredennick recently urged ministers to spend more NHS money on alternative therapies such as homeopathy and acupuncture to treat patients. It seems to me that, for him and other quackery promoters, evidence and science are issues beyond comprehension. Mr Tredinnick also disclosed the fact that he received acupuncture at a Chinese medical clinic just before the Commons debate on cancer strategy – a regular treatment he credits with keeping him healthy.
Tredennick told his fellow MPs: “I was talking there to practitioners about what they are able to do for cancer patients, and there is actually a very long list of types of cancer that can be treated using traditional Chinese herbal medicine.“ One, cervical cancer, two, non-Hodkins lymphoma, three, HIV, four, colon cancer, five… six, breast cancer, seven, prostate cancer. And so the list goes on. “I have in my constituency several constituents who I believe are alive today because they have used Chinese medicine.“ And the reason for that is what it does is it strengthens your system, and it strengthens the immune system, and it is very effective after cancer treatment. It deals with particular symptoms.”
This is by no means the first outburst of quackery-promotion by the Right Honourable Gentleman. I have a whole selection of quotes from him which I sometimes use for amusing my audience during public lectures. Because amusing he is; Tredennick seems to be utterly devoid of rational thought when it comes to the subject of alternative medicine, and often his statements make for comedy gold. This time, however, he might be sailing closer to the wind than he perhaps realizes: Under English law, it is an offence to claim that any treatment can cure cancer, I believe.
We all had to learn to laugh about unethical and dangerous nonsense the ‘Tredennicks of this world’ regularly claim about alternative medicine. Laughing is the only solution for coping with such idiocy, I am afrid. If we don’t laugh, we have to consider taking it seriously – and this is a truly frightening prospect, particularly considering that this guy actually sits in parliament and has the power to influence our lives.
This is the title of a lecture I was asked to give yesterday to an audience of palliative cancer care professionals. During the last days, I have therefore thought about the Anderson-tale quite a bit. For those who don’t know the story (is there such a person?), it is a tale about two con-men who promise the emperor new clothes which, they claim, are invisible to anyone who is incompetent or stupid. When the Emperor parades before his subjects in his new clothes, no one dares to say that he is, in fact, naked. Finally, a child cries out, “But he isn’t wearing anything at all!”
The story is obviously a metaphor for a scenario where something is generally accepted as being good simply because nobody has the courage or insight to oppose popular opinion – nobody except a naïve child, that is. It is a fitting tale for alternative medicine and a superb one to depict my own personal history.
It got more fascinating the more I thought about it. As a metaphor for alternative medicine it offers at least four different perspectives:
- The quacks seem to get away with even the most obvious lies.
- The VIP is too gullible and vain to realise that he is being done.
- The sycophants are happy to play along because they hope to benefit from not speaking the truth.
- The child has not yet learnt how to ‘play along’ and therefore speaks the truth without a second thought.
The parallels to the current boom in alternative medicine are, I think, so striking that I do hardly need to explain them. The parallels to my own past, however, might require some explanation.
During the last 25 years, I have met more quacks making false claims than I care to remember. Some virtually sold the emperor clothes that were non-existent. One even offered him a report that suggested that the UK’s ailing healthcare system could be saved by maximizing the use of bogus therapies, such as homeopathy, for serious illnesses – more about that in a minute.
I even once had the honour to meet the emperor, our Queen – and it is not she who I here refer to. She was not at all gullible. The emperor I mean is actually our future emperor, the Queen’s son. He has provided us with ample evidence to doubt his intelligence, and it is he who has fallen for the con-men I refer to.
The sycophants are those ‘experts’ who Charles tends to assemble around him. They do know better, I think, but they do not tell him the truth because they know that people like Charles cannot tolerate any facts that fail to confirm his views. So they duly applaud even the silliest of notions hoping to keep their place in the entourage.
And the naïve child? Yes, of course, that’s me. When I arrived in Exeter 23 years ago, I did think that I was appointed to employ science as a tool to find the truth. Once I had done the research, I shouted: “But he isn’t wearing anything at all!” – metaphorically speaking, of course.
And that was something neither the emperor nor the sycophants could tolerate. When I said what had to be said about the ‘Smallwood Report’, the combined effort of the emperor and his sycophants put an end to my activities in Exeter.
Yes, in relation to alternative medicine, the story of THE EMPEROR’S NEW CLOTHES could be most interesting!
But did the palliative care experts invite me to tell it?
The more I thought about it, the more I doubted this.
Eventually, I arrived at the conclusion they wanted to hear about the evidence for or against alternative treatments for cancer. A pity really, because arguably the other aspect are much more entertaining.
I have published many articles on the risks of various alternative treatments (see for instance here, here, here, here, here and here) – not because I am alarmist but because I have always felt very strongly that, for a researcher into alternative medicine, the most important issue must be to make sure users of these therapies are as safe as possible. Usually I differentiated between direct and indirect risks. The former relate to the risks of the treatment and include, for instance, liver damage caused by a herbal remedy or stroke due to neck manipulation. The latter are mainly due to the poor, often irresponsible advice given by many therapists.
A recent article adopted the same terminology when reviewing the risks of alternative medicine specifically for cancer patients. As the indirect risks are often neglected, I will here quote the relevant section of this paper in full:
…Health care physicians and oncology experts have an ethical responsibility to initiate the communication regarding the use of complementary therapies with cancer patients. However, according to data obtained from this literature review, oncology doctors and physicians will discuss complementary therapies only when a patient him/herself raises this issue within a consultation. This passive attitude was linked to a lack of sufficient scientific evidence for positive outcomes of complementary therapies found in high quality randomized controlled trials (RCTs). Oncology nurses, on the other hand, sometimes actively promote complementary modalities that they find to correspond with their vision of holistic care.
According to the included studies, complementary providers often differ from conventional health care providers in their understanding of treatment concepts, philosophies and diagnostic procedures. This leads to different models of disease causality (cells, blood, nerves vs. energy, vital force, meridians) and treatment philosophy (reductionism vs. holism). As many complementary providers are philosophically oriented towards personal and spiritual growth, patients may feel guilty if the disease continues to advance despite the patients’ best spiritual and mental efforts. According to Broom and colleagues, such philosophies may also give patients false hope of recovery.
Another indirect risk connected to the combination of conventional and complementary treatment in cancer care is the lack of regulation and standardized education in many countries. Currently, there are, for example, no standard training requirements for complementary providers working in cancer care or any other health care setting in the EU. According to Mackareth et al., complementary providers in England need specific training to learn how to practice safely.
Moreover, there is a need for common medical terminology to bridge the communication gap between health care providers working outside the conventional health care system. Common medical terminology may reduce the existing communication gap between conventional and complementary providers about mutual patients. To minimize communication gap between physicians, oncology experts and complementary providers, a medical complementary record should include a treatment plan with conventional and complementary diagnosis, explanation of terminology, possible treatment interactions, description of the complementary treatment plan and goals. If possible, the quality of any complementary supplement given should be reported.

As I said, I find it important to discuss the indirect risks of alternative medicine, and I am therefore pleased that the authors of this article addressed them. At the same time, I find their text remarkably tame.
Why are they not more open and forceful about what, after all, amounts to a serious public health issue? The answer might be simpler than expected: most of them are affiliated with the ‘National Research Center in Complementary and Alternative Medicine (NAFKAM), UiT The Arctic University of Norway, Tromsø, Norway’. Could it be that open warnings about outright quackery is not what suits this unit?
So, what might be an open and frank approach to discussing the indirect risks of alternative medicine? In my view, it should make several points abundantly clear and transparent:
- Alternative practitioners (APs) are usually not trained to advise patients responsibly, particularly in cases serious disease.
- The training of APs is often inadequate and sometimes resembles more to brain-washing than to proper education.
- Consequently, APs often woefully over-estimate what their therapy can achieve.
- The patients of APs are often desperate and ready to believe even the tallest tales.
- APs have a huge conflict of interest – in order to make a living they need to treat as many patients as possible and are therefore not motivated to refer them to more suitable care.
- APs are frequently in denial when it comes to the risks of their treatments.
- APs are not educated such that they understand the full complexities of serious illness.
- As a result, APs far too often misguide their patients to make tragically wrong choices thus putting their health at serious risk.
- In most countries, the regulators turn a blind eye to this huge problem.
These are by no means trivial points, and they have nothing to do with a ‘turf war’ between conventional and alternative medicine. They relate to our ethical duty to keep our patients as safe as we can. It has been estimated that, in oncology alone, 1 – 5% of deaths are due to patients opting to have alternative instead of conventional treatments. This amounts to an unbearably high absolute number of patients dying prematurely due to the indirect risks of alternative medicine.
It is high time, I think, that we tackle this issue systematically and seriously.
This press-release just came to my attention:
Today, with the stroke of his pen, Governor Tom Wolf adds Pennsylvania to the list of states that acknowledge the value of alternative healthcare from a qualified professional. Pennsylvania becomes the 21st U.S. jurisdiction to regulate naturopathic medicine. The new law HB516 regulates naturopathic doctors; ensuring patients can trust that their wellness professional holds a graduate degree from an accredited naturopathic medical school.
Heidi Weinhold, N.D. and Legislative Chair of the Pennsylvania Association of Naturopathic Physicians (PANP), says, “This is a historic day for naturopathic medicine. The governor’s approval will throw open the doors for more Pennsylvania students to choose this academic course of study. Then, they can return home from a four-year graduate program to set up a practice as a naturopathic doctor.”
The PANP members worked for the last 16 years with the state legislature to advance the much-needed recognition of this growing medical field. Their goal was to increase the credibility and minimize the confusion between professionals with an advance degree and the self-study practitioner. “Naturopathic professionals also seek to better coordinate and collaborate with medical professionals across the spectrum. We believe in integrative care, and this law gives us the stature we need to work N,” explains Dr. Weinhold.
Under the new law, the terms Naturopathic Doctor and ND will be reserved exclusively for those who have attended four-year, post-graduate level programs at institutions recognized by the United States Department of Education. “This protects the scope-of-work and title for graduates from an accredited N.D. program,” offers Dr. JoAnn Yanez, executive director of the Association of Accredited Naturopathic Colleges.
Naturopathic Doctors are currently practicing at Cancer Treatment Centers of America in Philadelphia, as well as the University of Pittsburgh Medical Centers, where they work side by side with medical doctors in an integrative setting. More patients could be served in this manner once naturopathic doctors are registered in this state. Both Penn State Hershey Medical Center and West Penn Allegheny General Hospital have indicated that they would hire Naturopathic Doctors if they were registered in the state.
“The PANP will be working over the next year on implementation of the legislation in order that NDs can begin to register with the Board of Medicine. A number of Representatives and Senators have encouraged us to come back to the legislature next session in order to expand the scope of this bill. We are very encouraged about the future of naturopathic medicine in Pennsylvania,” says Dr. Marie Winters, manager of the Naturopathic Medicine Department of the Cancer Treatment Centers of America and president of PANP.
The law will go into effect January 1, 2018.
Pennsylvania joins these other jurisdictions which regulate naturopathic medicine: Alaska, Arizona, California, Colorado, Connecticut, District of Columbia, Kansas, Maine, Maryland, Minnesota, Montana, New Hampshire, North Dakota, Oregon, Rhode Island, Utah, Vermont, Washington, Puerto Rico and U.S. Virgin Islands, and these provinces in Canada: Alberta, British Columbia, Manitoba, Ontario, Saskatchewan.

Here are a few comments and issues that I find remarkable about this announcement:
- Naturopaths are called ‘naturopathic doctors’, yet in the same sentence it is pointed out that they are ‘wellness professionals’. I am not sure what the latter, woolly term is supposed to mean – perhaps that naturopathy cannot effectively treat diseases?
- The document speaks of ‘accredited naturopathic medical schools’. Has anyone checked the utter nonsense that is being taught there? The answer is yes, Britt Marie Hermes has, and her verdict is truly depressing and devastating.
- Naturopaths instantly interpret the new regulation as a ‘governor’s approval’ and ‘recognition’. It shows why alternative practitioners want to be regulated: they foremost crave the APPROVAL and the RECOGNITION they clearly do not deserve.
- Naturopaths believe in ‘integrative care’ – of course they do, because this is nothing but a ploy for smuggling quackery into evidence-based medicine (EBM).
- Naturopaths want to be ‘peer-to-peer with other disciplines’ – but they are unable to show that their interventions generate more good than harm. This effectively is an attempt to place quackery on the same level as EBM.
- Naturopaths already treat cancer patients in the state! Really? Do they use Laetrile, or homeopathy?
- Naturopaths are portrayed as being a benefit to public health. Has anyone considered that the opposite might be the case? See for instance here and here.
Use of complementary and alternative medicine (CAM) is common among cancer patients, not least because all sorts of claims are being made for CAM. One of these claims is that it prolongs survival. But does it improve survival? This new study from the US was aimed at finding out; specifically, the authors wanted to determine whether CAM use impacts on the prognosis of breast cancer patients.
Health Eating, Activity, and Lifestyle (HEAL) Study participants (n = 707) were diagnosed with stage I-IIIA breast cancer. Participants completed a 30-month post-diagnosis interview including questions on CAM use (natural products such as dietary and botanical supplements, alternative health practices, and alternative medical systems), weight, physical activity, and comorbidities.
Outcomes were breast cancer-specific and total mortality, which were ascertained from the Surveillance Epidemiology and End Results registries in Western Washington, Los Angeles County, and New Mexico. Cox proportional hazards regression models were fit to data to estimate hazard ratios (HR) and 95 % confidence intervals (CI) for mortality. Models were adjusted for potential confounding by socio-demographic, health, and cancer-related factors.
Among the 707 participants, 70 breast cancer-specific deaths and 149 total deaths were reported. 60.2 % of participants reported CAM use post-diagnosis. The most common CAM were natural products (51 %) including plant-based estrogenic supplements (42 %). Manipulative and body-based practices and alternative medical systems were used by 27 and 13 % of participants, respectively. No associations were observed between CAM use and breast cancer-specific (HR 1.04, 95 % CI 0.61-1.76) or total mortality (HR 0.91, 95 % CI 0.63-1.29).
The authors concluded that CAM use was not associated with breast cancer-specific mortality or total mortality. Randomized controlled trials may be needed to definitively test whether there is harm or benefit from the types of CAM assessed in HEAL in relation to mortality outcomes in breast cancer survivors.
These findings tie in with the results of several other studies, some of which even seem to show that cancer patients who use CAM die sooner than those who don’t. I have previously pointed out that this could have several reasons, for instance:
1) Some patients might use ineffective alternative therapies instead of effective cancer treatments thus shortening their life and reducing their quality of life.
2) Other patients might employ alternative treatments which cause direct harm; for this, there are numerous options; for instance, if they self-medicate St John’s Wort, they would decrease the effectiveness of many mainstream medications, including some cancer drugs.
3) Patients who elect to use alternative medicine as an adjunct to their conventional cancer treatment might, on average, be more sick than those who stay clear of alternative medicine.
Therefore, I totally agree with the conclusions of the present paper: Randomized controlled trials may be needed to definitively test whether there is harm or benefit…
Antrodia cinnamomea (AC) is a fungus which is used in Taiwan as a remedy for cancer, hypertension, hangover and other conditions. There are several commercial AC products and the annual market is worth over $100 million in Taiwan alone.
Several studies have suggested anti-cancer properties in vitro but few clinical trials have been reported. Now Taiwanese researchers published a double-blind, randomized clinical study to investigate whether AC had acceptable safety and efficacy in advanced cancer patients receiving chemotherapy.
Patients with advanced and/or metastatic adenocarcinoma, performance status (PS) 0-2, and adequate organ function who had previously been treated with standard chemotherapy were randomly assigned to receive routine chemotherapy regimens with AC (20 ml twice daily) orally for 30 days or placebo. The primary endpoint was 6-month overall survival (OS); the secondary endpoints were disease control rate (DCR), quality of life (QoL), adverse event (AE), and biochemical features within 30 days of treatment.
A total of 37 subjects with gastric, lung, liver, breast, and colorectal cancer (17 in the AC group, 20 in the placebo group) were enrolled in the study. Disease progression was the primary cause of death in 4 (33.3 %) AC and 8 (66.7 %) placebo recipients. Mean OSs were 5.4 months for the AC group and 5.0 months for the placebo group (p = 0.340), and the DCRs were 41.2 and 55 %, respectively (p = 0.33). Most hematologic, liver, or kidney functions did not differ significantly between the two groups, but platelet counts were lower in the AC group than in the placebo group (p = 0.02). QoL assessments were similar in the two groups, except that the AC group showed significant improvements in quality of sleep (p = 0.04).
The above figure shows the survival curves for both groups.
The authors concluded as follows: Although we found a lower mortality rate and longer mean OS in the AC group than in the control group, AC combined with chemotherapy was not shown to improve the outcome of advanced cancer patients, possibly due to the small sample size. In fact, the combination may present a potential risk of lowered platelet counts. Adequately powered clinical trials will be necessary to address this question.
I agree, the survival curve looks promising. But we must not get carried away: this was a tiny sample size and a relatively short treatment period. Thus the difference could be a coincidence or an artefact.
The investigators are sufficiently cautious in the interpretation of their findings, and most of us would probably agree that it is necessary to submit such traditional remedies to proper scientific tests. Yet, I feel a sense of unease when I read such articles.
On the one hand, it is possible that such investigations meaningfully contribute to progress. On the other hand, I wonder whether they merely end up providing a significant boost to the trade of bogus remedies sold at high prices to desperate patients. Do the benefits really out-weigh the risks? We will probably never know.
But to minimize the risk, the authors should now swiftly conduct a more definitive trial and create some clarity about the value or otherwise of this traditional cancer remedy.
