Currently, over 50 000 000 websites promote alternative medicine, and consumers are bombarded with information not just via the Internet, but also via newspapers, magazines and other sources. This has the potential of needlessly separating them from their cash or even seriously harming their health. As there is little that protects us from greedy entrepreneurs and over-enthusiastic therapists, we should think about protecting ourselves. Here I will provide five simple tips that may fortify you against fake news in the realm of alternative medicine.
Imagine you read somewhere that the condition you are affected by is curable (or at least improvable) by THERAPY XY. It is only natural that you are exited by this news. Before you now rush to the next health shop or alternative medicine centre, it is worth asking yourself the following questions:
- Is the claim plausible? As a rule of thumb, it is fair to say that, if it sounds too good to be true, it probably is too good to be true. Not so long ago, UK newspapers reported that a herbal mixture called ‘CARCTOL’ had been discovered to be an efficacious and safe cancer cure (before that, it was Essiac, shark cartilage, Laetrile and many more). I only needed a minimal amount of research to find that the claim had no basis in fact. Come to think of it, it is not plausible that any alternative therapy will ever emerge as a miracle cure for any condition, particularly a serious disease like cancer. It is also not plausible that a herbal mixture would ever prove to be a cure for a wide range of different cancers. The very idea of such ‘cures’ is a contradiction in terms. If an alternative therapy ever did turn out to be efficacious, it would become mainstream even before the clinical tests to prove its efficacy are fully concluded. The notion of an alternative cure presumes that conventional scientists and clinicians reject a treatment simply because it originated from the realm of alternative medicine. There is no precedent that this has ever occurred, and I am sure it will never happen in future.
- What is the evidence for the claim? In the case of CARCTOL, the claim was based on a UK doctor apparently observing that, in several patients, tumours had been melting like butter in the sun after they took this herbal mixture. One particularly irresponsible headline read: “I’ve seen herbal remedy make tumours disappear, says respected cancer doctor.” This, however, is no evidence but mere anecdotes, and we confuse the two at our peril. Remember: the plural of anecdote is anecdotes, not evidence. With anecdotes, we can never be sure about cause and effect. Therapeutic claims must be based on good evidence, e.g. controlled clinical trials.
- Who is behind the claim? In the UK, the CARCTOL claim emerged around 2004 and originated mainly from Dr Rosy Daniel. In the above newspaper article, she was called ‘a respected cancer doctor’. Personally, I do NOT ‘respect’ someone who makes claims of this nature without having good evidence. And a ‘cancer doctor’ is usually understood to be an oncologist; to the best of my knowledge, Dr Daniel is NOT an oncologist. In fact, she now calls herself a ‘Lifestyle and Integrative Medicine Consultant’. Faced with an important new health claim, one should always check who is behind it. Check out whether this person is reputable and free of conflicts of interest. An affiliation to a reputable university is usually more convincing than being a director of your own private heath centre.
- Where was the claim published? The CARCTOL story had been published in newspapers – and nowhere else! Even today, there is only one Medline-listed publication on the subject. It is my own review of the evidence which, in 2004, concluded that “The claim that Carctol is of any benefit to cancer patients is not supported by scientific evidence.” *** If important new therapeutic claims like ‘therapy xy cures cancer’ are reported in the popular media, you should always check where they were first published (or simply dismiss it without researching it). It is unthinkable that such an important claim is not made first in a proper, peer-reviewed article in a good medical journal. Go on ‘Medline’, conduct a quick search and find out whether the new findings have been published. If the claim does not come from peer-reviewed journals, forget about it. If it has been published in any journal that has alternative, complementary, integrative or similar terms in its name, take it with a good pinch of salt.
- Is there money involved? In the case of CARCTOL, the costs were high. I was called once by a woman who had read my article telling me that she was pursued by the doctor who had treated her husband. Tragically, the man had nevertheless died of his cancer, and the widow was now pursued for £8 000 which she understandably was reluctant to pay. Many new treatments are expensive. So, high costs are not necessarily suspicious. Still, I advise you to be extra cautious in situations where there is the potential for someone to make a fast buck. Financial exploitation is sadly rife in the realm of alternative medicine.
A similar checklist originates from a team of experts. Researchers from Uganda, Kenya, Rwanda, Norway, and England, worked to identify the most important ideas a person would need to grasp thinking critically about health claims. They came up with excellent points:
- Just because a treatment is popular or old does not mean it’s beneficial or safe.
- New, brand-name, or more expensive treatments may not be better than older ones.
- Treatments usually come with both harms and benefits.
- Beware of conflicts of interest — they can lead to misleading claims about treatments.
- Personal experiences, expert opinions, and anecdotes aren’t a reliable basis for assessing the effects of most treatments.
- Instead, health claims should be based on high-quality, randomized controlled trials.
Alternative medicine can easily turn into a jungle or even a nightmare. Before you fall for any dubious claim that THERAPY XY is good for you, please go through the simple sets of questions above. This might protect you from getting ripped off or – more importantly – from getting harmed.
*** After this article had been published, I received letters from layers threatening me with legal action unless I withdrew the paper. I decided to ignore them, and no legal action followed.
Olivia Newton-John is postponing her June U.S. and Canadian concert tour dates, as the back pain that initially caused her to postpone the first half of her concert tour, has been diagnosed as bone metastases form her earlier breast cancer. She now intends to complete a short course of photon radiation therapy along with alternative therapies for improving her quality of life. “I decided on my direction of therapies after consultation with my doctors and natural therapists and the medical team at my Olivia Newton-John Cancer Wellness and Research Centre in Melbourne”, Newton-John said. The actress had been diagnosed with breast cancer in 1992. At that time, she underwent chemotherapy after initially trying alternative treatments like acupuncture and homeopathy.
Olivia Newton-John’s daughter Chloe Lattanzi has said her mum would use cannabis oil to aid in her fight against cancer, while long-time friend John Farnham has thrown his support behind the singer. Lattanzi owns a legal marijuana farm in Oregon and said that her mum would also use other natural healing remedies plus modern medicine in addition to cannabis oil to help her battle the deadly disease for the second time.
The Olivia Newton-John Cancer Wellness & Research Centre is a treatment centre of Austin Health, an Australian public hospital. They say that “anyone with a referral from their doctor can be treated here, regardless of the stage of their treatment or insurance status. At the ONJ Centre your care is built around your individual needs. This includes your physical, psychological and emotional health. Every patient is surrounded by a multidisciplinary team of cancer specialists, allied health and wellbeing therapists. Your dedicated treatment team work together to guide you through your optimal treatment pathway. Learn more about the cancer treatments we deliver at the ONJ Centre, how we support you through your care, and find answers to commonly asked questions.”
Their therapies include acupuncture and several other alternatives used for palliation, but the site seems refreshingly free of false claims and quackery. On their website, they say that “palliative care assists patients who have a life limiting illness to be as symptom free as possible. We work with you to meet your emotional, spiritual and practical needs in a holistic way. Our support is also extended to your family and carers.”
Altogether, this seems like a fairly reasonable approach. Olivia might have learnt a lesson the hard way when her initial breast cancer did not respond to homeopathy. Let’s hope she does get her metastases under control with cutting edge cancer care and is able to keep her spirits up with the additional help of a little complementary medicine.
The current volume of the ‘Allgemeinen Homöopathischen Zeitung’ contains all the abstracts of the ‘Homeopathic World Congress 2017’ which will be hosted in Leipzig, 14-17 July this year by the ‘Deutschen Zentralvereins Homöopathischer Ärzte’ under the patronage of the German Health Secretary, Annette Widmann-Mauz. As not many readers of this blog are likely to be regular readers of this important journal, I have copied six of the more amusing abstracts below:
A male patient with bilateral solid renal mass was investigated and given an individualized homeopathic remedy. Antimonium crudum in 50000 potency was selected after proper case taking and evaluation. Investigations were done before and after treatment. Follow ups took place monthly. Results The patient had symptomatic relief from pain in flanks, acute retention and hematuria. The ultrasonography suggests a reduction in size of both lesions over a period of two years. A small number of lymph nodes of the para-aortic group are still visible. There is a normal level of urea and creatinine, no anemia or hypertention. The patient is surviving since 2014. Conclusion In the present day when malignancies are treated with surgeries, chemo and radiotherapies, homeopathy has a significant role to play as seen in the above case. This case with bilateral solid renal mass, probably a renal cell carcinoma, received an individualized homeopathic remedy-treatment compliant with the totality of symptoms, and permitted the patient to live longer without anemia, hypertension, anorexia or weight loss. The quality of life was maintained without the side effects of surgery, radiotherapy and chemotherapy. Acute retentions, which he used to suffer also remained absent, thereafter. The result of this case suggests to take up further studies on individualized homeopathic treatment in malignant diseases.
Urinary tract infections (UTI) are often a complaint in the homeopathic practice, mainly as uncomplicated infections in the form of a one time event. Some patients, however, have a tendency to develop recurrent or complicated urinary tract infections. Methods It is shown on the basis of case documentation that UTI should be treated homeopathic, variably. The issue of prophylaxis will be discussed. Results If there is a tendency to complicated UTI, chronic treatment after case taking of the symptom-totality of the affected must take place during a free interval. In contrast, the chronically recurring and flaming up of UTI, as well as the uniquely occurring of uncomplicated UTI, are handled as an acute illness. The treatment is based on the striking, characteristic symptoms of the infected. Conclusion The homeopathic treatment of UTI in the acute case of uncomplicated forms is usually very successful, The chronic treatment of complicated UTI shows certain difficulties. A safe homeopathic prophylaxis, in terms of conventional medicine, is problematical.
The homeopathic clinic of the Municipal Public Servant Hospital of São Paulo (HSPM – Brazil) has among patient records some cases of thyroid gland diseases (hypothyroidism or hyperthyroidism), which were treated whith the systemic homeopathic method of Carillo. This study evaluates patients with diseases of thyroid gland, analyzing improvements using a Iodium-like equalizer, adjacent to the systemic medication. The reviewed 21 cases using Iodium equalizer for the disease, adjacent to the systemic medication, in the homeopathic clinic of the HSPM, from 2000 to 2013. In four cases, it was possible to reduce the dose of allopathic medicine and finally terminate it due to normalization of the thyroid gland function. There was one case of hyperthyroidism and it was possible to terminate the use of methimazole. There were four cases, in which the function of the thyroid gland was normalized without the associated use of hormone. In three cases it was possible to reduce the dose of hormone. There were nine cases, in which it was not possible to reduce the dose of the hormone. In cases where there was an improvement applying homeopathic treatment, TSH and free T4 returned to the normal reference value. In cases that were not effective, TSH and free T4 had not normalized. Therefore, the effectiveness of Iodium depends on the ability and stability of the gland thyroid to increase or decrease hormone production, in addition to the treatment of a chronic disease, that affects the thyroid gland.
Cystitis composes infections in the urinary system, especially bladder and urethra. It has multiple causes, but the most common is infection due to microorganisms such as E. coli, streptococcus, staphylococcus etc. If the system is attacked by pathogenetic agents, the defense must include more powerful noxious agents which can fight and destroy the attacking organisms, here is the role of nosodes. Nosodes are the potentised remedies made up from dangerous noxious materials. The use of nosodes in cystitis is based on the aphorism 26– Therapeutic Law of Nature: A weaker one is always distinguished by the stronger one! Colibacillinum, streptococcinum, staphylococcinum, lyssinum, medorrhinum, psorinum and tuberculinum are useful in handling cystitis relating to the organism involved [as found in urine test] and symptom similarity. Method An observational prospective study on a group of 30 people proves the immediate, stronger defensive action of nosodes. Result Amazing! Nosodes given in low potency provided instant relief to patients. Repetition of the same, over several months offered immunity for further attacks of cystitis, as Hering had already testified nosodes have prophylactic action. Conclusion According to law of similia – as per the pathology, as per the defense! By inducing a strong artificial disease, homeopathy can eliminate the natural disease from the body. Usually nosodes are used as intercurrent drugs which play the role of catalysts, on the journey to recovery, but they are also very effective in cystitis as an acute remedy. Acute cystitis is a very troublesome state for the patients, to cure it homeopathy has an arsenal of nosodes.
In 1991, no antiretroviral therapy (ART) treatment was available. The Central Council for Research in Homeopathy had established a clinical research unit at Mumbai for undertaking investigations in HIV/AIDS. So far 2502 cases have been enrolled for homeopathic treatment and three studies have been published since then. In this paper we will highlight the impact of long term homeopathic management of cases, which have been followed up for more than 15 years. Method The HIV positive cases enrolled in different studies are continuously being managed in this unit and even after study conclusion. All the cases are being treated solely with individualised homeopathy. The cases are assessed clinically (body weight, opportunistic infections, etc.) as well as in respect to CD4 counts and CD4/CD8 ratio. Results The CD4 count was maintained in all patients, except in one case. Three patients had the CD4 level in the range of 500–1200, four in the range of 300–500, one had a 272 CD4 count. There has been a decline of CD4/ CD8 ratio since baseline, but the patients have maintained their body weights and remained free from major HIV related illnesses and opportunistic infections. The frequently indicated remedies were pulsatilla pratensis, lycopodium clavatum, nux vomica,tuberculinum bovinum, natrum muriaticum, rhus toxicodendron, medorrhinum, arsenicum album, mercurius solubilis, thuja occidentalis, nitic acid, sulphur, bryonia alba and hepar sulph. Conclusion In the emergent scenario of drug resistance and adverse reactions of ART in HIV infections, there may be a possibility of employing homeopathy as an adjuvant therapy to existing standard ART treatment. Further studies are desirable.
In the last 20 years we have treated in the Clinica St. Croce many patients with cancer. We often deal with palliative states and we aim at pain relief and improvement of life-quality, and if possible a prolongation of life. Is this possible by prescribing a homeopathic therapy? Methodology The exact application and the knowledge of the responses to the Q-potencies often give indications for the correct choice of remedy. Acute conditions of pain often need a more frequent repetition of the C-potencies needed for pain relief. Results Even with severe pain or in so-called final stages homeopathy can offer great assistance. On the basis of case reports from Clinica St. Croce, the procedure for the homeopathic treatment of cancer, and the treatment of pain and final states will be illustrated and clarified. In addition, some clinically proven homeopathic remedies will be presented for the optimal palliation in the treatment of end-states and accompanying the dying. Conclusions With the precise application and knowledge of the responses to the Q- and C-potencies, the homeopathic doctor is given a wonderful helper to treat even the most serious palliative states and can accomplish, sometimes, a miraculous healing.
MY BRIEF COMMENT
These abstracts are truly hilarious and show how totally unaware some homeopaths are of the scientific method. I say ‘some’, but perhaps it is most or even all? How can a scientific committee reviewing these abstracts let them pass and allow the material to be presented at the ‘World Congress’? How can a Health Secretary accept the patronage of such a farce?
These abstracts are therefore not just hilarious but also truly depressing. If we had needed proof that homeopathy has no place in real healthcare of today, these abstracts would go a long way in providing it. To realise that politicians, physicians, patients, consumers, journalists etc. take such infantile nonsense seriously is not just depressing but at the same time worrying, I find.
In my view, the website of ‘FOODS 4 BETTER HEALTH’ should be more aptly called FOOD FOR QUICKER DEATH. At least this is the conclusion that came to my mind after reading their post on ‘Apricot Seeds: Nutrition, Health Benefits, and Their Role in Cancer Treatment’.
Under the heading ‘Apricot Seeds for Cancer Treatment’, we find the following explanations:
“Laetrile is a drug made from amygdalin. Apple seeds, Lima beans, plums, and peaches also contain amygdalin. Although laetrile isn’t a vitamin, it is labeled as amigdalina B17 or vitamin B17.
Dr. Kanematsu Sugiura received highest honors from the Japan Medical Association for his outstanding contributions in cancer research. He found that laetrile prevented the spread of malignant lung tumors in 10 to 20% of laboratory mice. Meanwhile, the mice given plain saline showed that lung tumor spread in 80 to 90% of the subjects. The study shows that laetrile reduces the spread of cancer and isn’t a cure for cancer.
According to a study published in the Public Library of Science, amygdalin blocks the growth of bladder cancer cells. The researchers studied the growth, proliferation, clonal growth, and cell cycle progression.
According to another study published in the International Journal of Immunopharmacology, the viability of human cervical cancer HeLa cell line was significantly inhibited by amygdalin. The researchers found apoptosis in amygdalin-treated HeLa cells.
However, a study published in The New England Journal of Medicine showed no substantial benefit of amygdalin on cancer patients. In fact, the blood cyanide levels of patients who received the substance intravenously increased alarmingly. But, the levels were relatively low in patients who received an oral dose.
A study conducted in 2002 at the Kyung Hee University in Korea found amygdalin to be helpful in killing prostate cancer cells. A similar study conducted on rats also linked the compound with pain relief, thus decreasing pain in cancer patients.
Amygdalin is considered as an alternative treatment for cancer. Since research so far has shown mixed and inconclusive results, apricot seeds may be helpful in the treatment of cancer, but shouldn’t be the only means to treat cancer. It is best to use it as a supplement with other cancer medications.”
END OF QUOTE
Cancer patients who read this sort of thing – and sadly the Internet offers plenty more of such irresponsible texts – might well decide to try Laetrile or start regularly consuming apricot seeds instead of chemotherapy or other effective cancer treatments. This decision would almost certainly hasten their deaths for two reasons:
- Amygdalin is NOT an effective treatment for cancer.
- It is highly toxic and would almost certainly kill some patients after chronic use.
To state, as the author of the above article does, that “research so far has shown mixed and inconclusive results” is irresponsible. The only thing that matters and the only message relevant for vulnerable patients is this: RESEARCH HAS NOT SHOWN THAT THIS STUFF WORKS FOR CANCER.
The purpose of this study was to evaluate whether the use of CAM among newly diagnosed breast cancer patients was associated with delays in presentation, diagnosis or treatment of breast cancer. A multi-centre cross-sectional design was used and the time points of the individual breast cancer patients’ journey from first visit, resolution of diagnosis and treatments were evaluated in six public hospitals in Malaysia.
All newly diagnosed breast cancer patients from 1st January to 31st December 2012 were recruited. Data were collected through medical records review and patient interview by using a structured questionnaire. Complementary and alternative medicine (CAM) was defined as the use of any methods and products not included in conventional allopathic medicine before commencement of treatments. Presentation delay was defined as time taken from symptom discovery to first presentation of more than 3 months. The time points were categorised to diagnosis delay was defined as time taken from first presentation to diagnosis of more than 1 month and treatment delay was defined as time taken from diagnosis to initial treatment of more than 1 month. Multiple logistic regression was used for analysis.
A total number of 340 patients participated in this study. The prevalence of CAM use was 46.5% (n = 158). Malay ethnicity (OR 3.32; 95% CI: 1.85, 5.97) and not interpreting symptom as cancerous (OR 1.79; 95% CI: 1.10, 2.92) were significantly associated with CAM use. The use of CAM was associated with delays in presentation (OR 1.65; 95% CI: 1.05, 2.59), diagnosis (OR 2.42; 95% CI: 1.56, 3.77) and treatment of breast cancer (OR 1.74; 95% CI: 1.11, 2.72) on univariate analyses. However, after adjusting with other covariates, CAM use was associated with delays in presentation (OR 1.71; 95% CI: 1.05, 2.78) and diagnosis (OR 2.58; 95% CI: 1.59, 4.17) but not for treatment of breast cancer (OR 1.58; 95% CI: 0.98, 2.55).
The authors concluded that the prevalence of CAM use among the breast cancer patients is high. Women of Malay ethnicity and not interpreting symptom as cancerous were significantly associated with CAM use. The use of CAM had significantly associated with delay in presentation and resolution of diagnosis. Difficulty in obtaining all medical records may have excluded patients who experienced delays in presentation, diagnosis or treatment but every precaution and resources were utilized to obtain record. This study suggests further evaluation of access to breast cancer care is needed as poor access may promote the use of CAM. However, since public hospitals in Malaysia are heavily subsidized and readily available to the population, CAM use may impact delays in presentation and diagnosis.
We know from previous studies that
- CAM-use is associated with poor adherence to cancer treatments,
- using CAM as an alternative to conventional treatments results in shorter survival of cancer patients,
and now we also know that CAM-use is associated with delayed presentation and diagnosis of cancer. This latter effect can have consequences that are just as serious as the other two. The later cancer is diagnosed, the poorer the prognosis and the shorter the survival.
These findings indicate that all healthcare professionals should be vigilant and inform patients as well as the general public that CAM-users are exposed to considerable dangers.
We have discussed this notorious problem before: numerous charities (such as one that treats HIV and malaria with homeopathy in Botswana, or the one claiming that homeopathy can reverse cancer) are a clear danger to public health. I have previously chosen the example of ‘YES TO LIFE’ and explained that they promote unproven and disproven alternative therapies as cures for cancer (and if you want to get really sickened, look who act as their supporters and advisors). It is clear to me that such behaviour can hasten the death of many vulnerable patients.
Yet, many such charities get tax and reputational benefits by being registered charities in the UK. The question is CAN THIS SITUATION BE JUSTIFIED?
Currently, the UK Charity commission want to answer it. Specifically, they are asking you the following question:
- Question 1: What level and nature of evidence should the Commission require to establish the beneficial impact of CAM therapies?
- Question 2: Can the benefit of the use or promotion of CAM therapies be established by general acceptance or recognition, without the need for further evidence of beneficial impact? If so, what level of recognition, and by whom, should the Commission consider as evidence?
- Question 3: How should the Commission consider conflicting or inconsistent evidence of beneficial impact regarding CAM therapies?
- Question 4: How, if at all, should the Commission’s approach be different in respect of CAM organisations which only use or promote therapies which are complementary, rather than alternative, to conventional treatments?
- Question 5: Is it appropriate to require a lesser degree of evidence of beneficial impact for CAM therapies which are claimed to relieve symptoms rather than to cure or diagnose conditions?
- Question 6: Do you have any other comments about the Commission’s approach to registering CAM organisations as charities?
I am sure that most readers of this blog have something to say about these questions. So, please carefully study the full document, go on the commission’s website, and email your response to: email@example.com . Don’t delay it; do it now!
How Jackfruit Kills Cancer… This title hardly left any doubt that jackfruit (Artocarpus heterophyllus Lam) is effective in curing cancer. The website continued in this vein:
“Jackfruit contains phytonutrients like lignans, saponins, and isoflavones, which have anticancer, antihypertensive, anti-ulcer, antioxidant, and anti-aging properties (2).
Lastly, the cancer-preventing abilities of the fruit are due in part to dietary TF-binding lectins (8). The pulp has the ability to reduce the mutagenicity of carcinogens and combat the proliferation of cancer cells (9).
In addition, the fruit contains carotenoids, flavonoids, and polyphenols that lower blood pressure, fight stomach ulcers, boost metabolism, support nerve function, and play a role in hormone synthesis. They also contain polysaccharides that boost immunity by interacting with white blood cells, including T cells, monocytes, macrophages, and polymorphonuclear lymphocytes (10).
Each part of the fruit and tree can be used: the flowers help stop bleeding in open wounds, prevent ringworm infestations, and heal cracks in dry feet while the root is used to treat skin diseases, asthma, and diarrhea. Additionally, the wood has a sedative and abortifacient effect…”
END OF QUOTE
To many desperate cancer patients, this would sound convincing, not least because the references provided by the author look sophisticated and seem to back up most of the claims made.
But where are the references to clinical trials showing that jackfruit does cure this or that type of cancer? Where is the evidence that it does “lower blood pressure, fight stomach ulcers, boost metabolism, support nerve function, and play a role in hormone synthesis”? Where are the data to prove that it does “boost immunity”?
I did conduct a ‘rough and ready’ Medline search and found precisely nothing; not a single clinical trial that would confirm the multiple claims made above.
You are not surprised?
Neither am I!
But what about the desperate cancer patients?
How many fell for the scam? How many gave up their conventional cancer treatments and used jackfruit instead? How many consumers know that it is not unusual for plants to contain lignans, saponins, isoflavones and many other ingredients that have amazing effects in vitro? How many know that this rarely translates into meaningful health effects in human patients?
We will never know.
One thing we do know, however, is that articles like this one can cost lives, and that alternative cancer cures are and always will be a myth.
Therapeutic Touch is a therapy mostly popular with nurses. We have discussed it before, for instance here, here, here and here. To call it implausible would be an understatement. But what does the clinical evidence tell us? Does it work?
This literature review by Iranian authors was aimed at critically evaluating the data from clinical trials examining the clinical efficacy of therapeutic touch as a supportive care modality in adult patients with cancer.
Four electronic databases were searched from the year 1990 to 2015 to locate potentially relevant peer-reviewed articles using the key words therapeutic touch, touch therapy, neoplasm, cancer, and CAM. Additionally, relevant journals and references of all the located articles were manually searched for other potentially relevant studies.
The number of 334 articles was found on the basis of the key words, of which 17 articles related to the clinical trial were examined in accordance with the objectives of the study. A total of 6 articles were in the final dataset in which several examples of the positive effects of healing touch on pain, nausea, anxiety and fatigue, and life quality and also on biochemical parameters were observed.
The authors concluded that, based on the results of this study, an affirmation can be made regarding the use of TT, as a non-invasive intervention for improving the health status in patients with cancer. Moreover, therapeutic touch was proved to be a useful strategy for adult patients with cancer.
This review is badly designed and poorly reported. Crucially, its conclusions are not credible. Contrary to what the authors stated when formulating their aims, the methods lack any attempt of critically evaluating the primary data.
A systematic review is more than a process of ‘pea counting’. It requires a rigorous assessment of the risk of bias of the included studies. If that crucial step is absent, the article is next to worthless and the review degenerates into a promotional excercise. Sadly, this is the case with the present review.
You may think that this is relatively trivial (“Who cares what a few feeble-minded nurses do?”), but I would disagree: if the medical literature continues to be polluted by such irresponsible trash, many people (nurses, journalists, healthcare decision makers, researchers) who may not be in a position to see the fatal flaws of such pseudo-reviews will arrive at the wrong conclusions and make wrong decisions. This will inevitably contribute to a hindrance of progress and, in certain circumstances, must endanger the well-being or even the life of vulnerable patients.
On 13 March, the UK Charity Commission published the following announcement:
This consultation is about the Commission’s approach to deciding whether an organisation which uses or promotes CAM therapies is a charity. For an organisation to be charitable, its purposes must be exclusively charitable. Some purposes relate to health and to relieve the needs of the elderly and disabled.
We are seeking views on:
- the level and nature of evidence to support CAM
- conflicting and inconsistent evidence
- alternative therapies and the risk of harm
- palliative alternative therapy
Last year, lawyers wrote to the Charity Commission on behalf of the Good Thinking Society suggesting that, if the commission refused to revoke the charitable status of organisations that promote homeopathy, it could be subject to a judicial review. The commission responded by announcing their review which will be completed by 1 July 2017.
Charities must meet a “public benefit test”. This means that they must be able to provide evidence that the work they do benefits the public as a whole. Therefore the consultation will have to determine what nature of evidence is required to demonstrate that a CAM-promoting charity provides this benefit.
In a press release, the Charity Commission stated that it will consider what to do in the face of “conflicting or inconsistent” evidence of a treatment’s effectiveness, and whether it should approach “complementary” treatments, intended to work alongside conventional medicine, differently from “alternative” treatments intended to replace it. In my view, however, this distinction is problematic and often impossible. Depending on the clinical situation, almost any given alternative therapy can be used both as a complementary and as an alternative treatment. Some advocates seem to cleverly promote their therapy as complementary (because this is seen as more acceptable), but clearly employ it as an alternative. The dividing line is often far too blurred for this distinction to be practical, and I have therefore long given up making it.
John Maton, the commission’s head of charitable status, said “Our consultation is not about whether complementary and alternative therapies and medicines are ‘good’ or ‘bad’, but about what level of evidence we should require when making assessments about an organisation’s charitable status.” Personally, I am not sure what this means. It sounds suspiciously soft and opens all sorts of escape routes for even the most outright quackery, I fear.
Michael Marshall of the Good Thinking Society said “We are pleased to see the Charity Commission making progress on their review. Too often we have seen little effective action to protect the public from charities whose very purpose is the promotion of potentially dangerous quackery. However, the real progress will come when the commission considers the clear evidence that complementary and alternative medicine organisations currently afforded charitable status often offer therapies that are completely ineffective or even potentially harm the public. We hope that this review leads to a policy to remove such misleading charities from the register.”
On this blog, I have occasionally reported about charities promoting quackery (for instance here, here and here) and pointed out that such activities cannot ever benefit the public. On the contrary, they are a danger to public health and bring many good charities into disrepute. I would therefore encourage everyone to use this unique occasion to write to the Charity Commission and make their views felt.
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.
