DCA Progress With Cancer

I posted on this two years ago and the effort continues to show serious promise.  What will happen soon enough is that this work will likely go to clinical trials in china first and gain approval there.  It appears very promising and even if it does not actually cure the disease, its clear ability to reverse the disease in much of the tumor will surely be hugely beneficial.

Hopefully this additional publicity will attract fresh funding and speed all this along.

In the meantime we do have clinical work underway with clearly positive results, but not again it does not appear to be fully curative.  I have added the second report to provide a realistic expectation for users who attempt this therapy.

DCA shown to kill cancer cells, but Big Pharma has no interest in this inexpensive potential cure
Thursday, September 26, 2013 by: Ethan A. Huff

(NaturalNews) A doctor and professor of medicine at the University of Alberta in Canada claims to have identified a novel substance that he says demonstrably kills cancer cells without causing harmful side effects and yet costs just pennies a dose. It is known as dichloroacetic acid, or DCA, and Dr. Evangelos Michelakis, M.D., believes it could be the next breakthrough treatment in the fight against cancer, that is if a government entity or pharmaceutical company would ever be willing to put forth appropriate funding for human clinical trials.

But this is unlikely to happen anytime soon, as there is currently no patent on DCA, and thus no incentive for private industry to research its potential benefits as a cancer treatment -- it's all about the money, after all, not public health. And governments are likely to ignore DCA as well, even though the medical research funds they disburse are intended for this very type of research, which is otherwise overlooked by the private sector in favor of more profitable undertakings.

But that has not stopped Dr. Michelakis from conducting his own research on animals, which thus far has shown some promising outcomes in targeting cancer cells and tumors. A recent report aired by CTV News in Canada explains how DCA, a drug that has actually been around for quite a while, is finding new vigor as an effective cancer treatment. What has long been used as a treatment merely for certain rare medical conditions could also be a, dare we say it, cure for cancer.

Based on initial trials, mice intentionally bred with certain human cancers responded positively to 
DCA when it was added to their drinking water. Brain, breast and lung tumors, it turns out, shrunk by an astounding 70 percent after just three weeks of treatment with DCA. And according to Dr. Michelakis, the drug compound did not cause any harmful side effects, leaving fully intact healthy cells and other tissues that are otherwise damaged by conventional chemotherapy or radiation treatments.

Not only this, but DCA also appears to help reanimate the energy-producing mechanisms found in healthy cells, which are known as mitochondria, giving them new life. Once activated and brought up to speed, these mitochondria elicit new abilities to trigger 
cancer apoptosis, or cancer cells essentially committing suicide on their own.

"These kinds of results, in my mind, are as good as it gets," stated Dr. Michelakis to CTV News about his findings. "We hope that we can attract the interest of universities here in Canada and in the United States."

Cheap, effective and patent-free means Big Pharma isn't interested

What it would take, according to general estimates, is about $100 million dollars and many years' worth of testing and trials to get DCA approved as an officially recognized treatment for cancer here in North America. Time will tell whether or not any of this actually happens though, as the pharmaceutical industry keeps a pretty tight lid on anything having to do with cancer treatments, since the cancer industry is a multi-billion dollar profit machine.

"This is exactly what we want is a drug that has activity, and that also has minimal side effects for patients," added Dr. Dario Altieri from the University of Massachusetts about the promising benefits of DCA.

Dr. Michelakis was also recently interviewed by television personality Glenn Beck:

Dr. Lemmo’s clinical experiences with DCA: intravenous and oral.

LEMMO Integrated Cancer Care Inc. is the first center in Canada & USA and most parts of the world since 2008 to use the intravenous form of DCA in cancer.

When Dr. Michelakis from the University of Alberta published his research showing how a simple vinegar-like chemical could have the ability to kill cancer cells in the laboratory back in October 2008 (and the following media attention he received) some of my more eager patients became enthralled with this potential chemotherapeutic agent and as a consequence so did my learning begin into DCA. Interestingly, the first data I found using DCA & cancer was published by a Dr. Pan from the Campbell Family Institute for Breast Cancer Research in Toronto back in April 2007.
As the name implies, DCA is short for Dichloro Acetic acid or Dichloro Acetate. It has a history in medicine for helping to treat a group of metabolic diseases (i.e. mitochondrial genetic diseases) in children primarily but also in adults for several decades. It has also been more loosely studied in other fields of medicine as well (i.e. exercise, COPD, heart failure, etc.). Because it is a rather simple chemical to make, it is considered a fairly inexpensive medicine. Moreover, because of its simplicity and low cost, most drug companies do not pay much attention to its use because of the more limited money or profit which can be generated as compared to medicines which are patentable or where the intellectual property (IP) can be secured.
I was happy to see the publicity that Dr. Michelakis had managed to stir about DCA and its relationship in cancer care and also exposing some of the politics behind getting non-patentable and lower cost medicines into more main-stream medicine. I even recall seeing Dr. Michelakis on CNN Larry King show on TV. As a consequence of this publicity, whether I wanted my patients to or not, the use of DCA for the treatment of their cancer(s) had become more of a common theme (i.e. it was becoming out of my control). Internet websites were popping up all over the place, selling DCA and providing treatment advice. Since that time, here in Canada and in the United States, DCA has been placed into a prescription category and its use has become more limited and regulated.
What I decided, in order to better help my patients the best I could, was to help those individuals who were interested in using DCA and at the very least monitor and try help avoid any unforeseen danger. When you are more specialized in the area of cancer like myself, you are better able to follow up patients, order the appropriate testing and perform the examinations to make sure that things are moving in the right direction or, conversely, to make suggestions or recommendations if things are going in the wrong direction.
Throughout the years of monitoring my patients with DCA, which included its eventual side-effect in causing numbness in the body (i.e. hands, feet, face, etc.), I had an inclination as to what its more dominant value would be in oncology medicine.

Case No. 1: anaplastic oligodendroglioma (1p/19q chromosome normal)—brain cancer

One of the first patients where I suggested the use of DCA was in a 39 year old woman who was diagnosed with a type of brain tumor known as an Anaplastic oligodendroglioma. She received surgery to get as much of the tumor the surgeon could (some was left behind) followed by radiation and the oral chemo pill known as Temozolomide which she continues to this day. The patient was stable for over a year receiving a comprehensive naturopathic oncology treatment alongside her standard oncology care. The patient thrived throughout. What was more unique about this patient versus others, however, is that even though her brain tumor was stable and she could be this way for many, many years as several of my patients have demonstrated, she had a goal of wanting the tumor completely gone! It was during this process (and eventual push) where DCA had come into question and her desire would become a greater reality.
I had noticed that DCA caused numbness in the hands & feet as a common side-effect which for me implied that the medicine managed to penetrate into the nervous system and possibly the brain and have an effect there. Based on these observations and gaining a better comfort with DCA, together, we decided to incorporate DCA into her protocol and see how things would go. However, in this case, while most patients were using DCA orally (in pill or powder form), I used an intravenous form that I used in helping out another patient with advanced ovarian cancer. To my knowledge, there was nobody else using DCA intravenously for the treatment of cancer anywhere and this was the first way on how I began using it. There is data using DCA by injection for non-cancer related medical conditions in research papers (i.e. COPD, exercise, congestive heart failure) which gave me some security about its potential use and safety for patients.
During the very first injection, the patient with brain cancer began to experience a “tingling” sensation in the area of the tumor site on her head. I had never seen this before in my years of specializing in cancer. I had initial concerns whether this was a good effect or a negative effect (which I later learned was OK). Together we continued a protocol of DCA twice weekly combined with low doses of vitamin C and B-vitamins mixed into the intravenous bag to theoretically help with any potential nervous system side-effects. Moreover, throughout, the patient also continued on the oral Temozolomide chemotherapy (there was no negative interaction). We had noticed that as time progressed, the tingling sensation in her head subsided and we were not certain what this had meant. The next MRI scan revealed again a stable image, and in the following several months, another MRI scan of the brain indicated the tumor was either dead or inactive. This observation was a wonderful outcome! Was this due to the combination of DCA and chemotherapy, DCA or the chemotherapy agent alone? Typically in this kind of brain tumor subtype, chemotherapy is considered not as effective and survival is poorer as compared to those with more favourable genetics (i.e. 1p/19q chromosome deletion). Following approximately 5 years the patient had stopped DCA along with other treatments including Temozolomide and she had a minor regrowth.  Surgery was decided to remove the region and she unfortunately passed away days later following a complication.

Case No. 2: NSCLC—Lung Cancer with brain metastasis

In another case, a 49 year old, non-smoker woman with a history of lung cancer better demonstrated the value of DCA and its effects on the body & brain. This patient was initially diagnosed with stage III lung cancer in 2006 and managed to respond amazingly well along with an extremely devoted Acupuncturist (i.e. Gerard Tan in Vancouver), an integrated cancer care approach, and the oral chemo-agent Tarceva for over 2 years. She had no signs of tumors throughout this period which was impressive in itself when you compare to the standard conventional statistics oncologists tell you. She too thrived during this time without any complications other than a rash which was a positive sign of the Tarceva. Unfortunately, following this golden time she presented with a low grade headache that was eventually determined to be a tumor in her brain in July 2008 (i.e. leptomeningial carcinomatosis and frontal lobe areas). She received radiation which did not appear to be helpful and she later received a surgical stent in her brain to help drain the fluid that tended to accumulate there from the cancer. Chemotherapy was no longer an option. When I eventually saw her in my office, both her hearing and vision was quite poor (damaged) as a side-effect of the radiation treatment, and she had lost a fair deal of weight. I personally felt that her time left with us was going to be very short (i.e. weeks)—I was wrong. The patient, like the previous, had a continued desire to live and she placed the pressure on me to help figure out a solution—For the second time. After a series of attempts in recommending treatment ideas, I introduced the possibility of DCA. I shared with the patient’s husband my personal views about using DCA and its potential to target cancers in the brain and nervous system. Consequently, together with the patient’s husband, I suggested for the patient to take DCA orally mixed in juice. In addition, the Acupuncturist Gerard Tan continued to provide treatments which included home visits by this time (which helped tremendously). I received a phone call a few days later from her devote husband after beginning DCA that he noticed his wife’s cognition was much improved. Weeks continued and so did the improvement. Eventually, a CT scan of the brain was ordered in December (3 months later) which showed the tumors had shrunk and the brain was stable (i.e. a response to leptomeningeal carcinomatosis is truly noteworthy since there is not much out there especially in this kind of scenario)! Interestingly though, the cancer in her lungs was growing and so it appeared to confirm my intuition about DCA’s predominant role for helping from the “neck up” and not so much from the “neck down”. What was good, however, is because the brain was not the primary problem anymore, this opened up chemotherapy options once again (she was also seeing a progressive medical oncologist which helped). She continued with DCA alongside for another 6 months which she later stopped. Three months later a repeat CT scan was ordered showing the brain continued to be stable even though the DCA had stopped but, unfortunately, not the lungs. After a long battle, the patient eventually passed away from her lung cancer disease about 1.5 years after the cancer had spread to the brain—a statistical wonder. I recall the oncologist telling the family that she would be deceased by Christmas 2008, ironically this turned out close to be true—but rather the year was incorrect (i.e. the following Christmas 2009). Interestingly, the brain was not the problematic area throughout this period even though DCA was stopped for 6 months prior to her passing.

Case No. 3: ATRT Grade IV – pediatric brain cancer

One of the youngest patients to have received DCA is a 21 month old infant with a diagnosis of Atypical Teratoid Rhabdoid Tumor (ATRT) Grade IV in April 2010. This type of brain cancer is extremely rare and aggressive. Because there have been so few cases of this disease (i.e. 5-7 cases across Canada), the conventional treatments & options are more experimental (i.e. like DCA) and the outcomes thus far have been quite poor. As a consequence of this, the parents decided to try less harmful treatment approaches first and if there were signs of disease progression, changing the game plan would be in order. One of the recommendations I suggested was the use of DCA amongst other things. While I’ve never used it in a paediatric setting, I knew it would be easy to take (mix in juice), it appeared safe, and I suspected that the potential positives outweighed the potential negatives (which I knew from adults the negative effects were reversible). Keep in mind that the primary use of DCA originated in children with metabolic diseases for several decades. Along with a naturopathic oncology program, we very cautiously began the use of DCA. At first, the medical oncologist has hesitant on the idea. As months passed and the infant did not show any signs of disease progression, the oncologist’s views began to change in a much more positive direction. Eventually, he began refilling the prescription of DCA for the family personally. On September, 2010, an MRI was ordered which revealed that the brain tumor had grown again. As you can imagine, this was a tremendous disappointment for everyone. However, the medical oncologist had felt that there was, in fact, a positive benefit. He suspected that the grow rate of the tumor had actually slowed down (i.e. instead of doubling every 15 days, it doubled every 30 days). Because the child was taking more than DCA as a treatment, we do not know which of the recommendations could help account for this effect. However, I hope that this can serve as an example for future parents and oncologists, to consider incorporating DCA, perhaps in higher doses, (and other naturopathic approaches) alongside other standards of care so that a better response can be ultimately attained for future children.

How DCA may work:

Patients often ask how DCA targets or impacts cancer in the body. It appears that a large part of how DCA works to kill cancer cells is by affecting their mitochondria function which is the “battery” center. DCA may interfere in the way the cancer cells use energy leaving them somehow more vulnerable. This effect is a newer way of targeting cancer cells from a metabolic point of view which stems from some very old research by Dr. Otto Warburg (i.e.the noble prize winner in 1931). Basically, he had shown that cancer cells use sugar to grow (i.e. the Warburg-Effect) and so by interfering in that metabolic energy process could potentially disrupt more sensitive growing cancers. There is also a recent study in a colon cancer cell line showing when the oxygen environment is normal, the cancer cells dies with DCA (i.e. apoptosis). However, it was also observed that when the environment is low in oxygen (i.e. hypoxic) DCA appeared to be more protective for the cancer which implies some caution, and that oxygen or oxidative mechanisms may also be involved in how it selectively kills cancer.  Research from 2013 suggests that DCA may also target and restore the immune system as a consequence of cancer leading to increased anti-tumor activity.

What are the concerning side-effects or toxicity concerns with using DCA?

We have to first remember that DCA is considered an environmental hazardous chemical of which chronic use has been shown in mice to be damaging to the liver and induce cancer growth. Ironically, the DCA doses used in animal toxicology experiments are very similar to those used clinically or as a medicine for the chronic or acute treatment of metabolic or cardiovascular diseases. So for patients who are considering long-term use of DCA, and especially in those who are using DCA for reducing their cancer recurrence risks (i.e. long-term users), this may be something to consider.
The more common side-effect which I see in practice is numbness & tingling symptoms. In my experience, this effect has been reversible upon discontinuation and we have patients who have been using DCA for over 2 years. We have not seen any point of concern thus far. Older patients may be more sensitive to these side-effects than younger patients. In unmonitored patients, there has been a recent published case where DCA caused very bad numbness and severe brain irritation (i.e. encephalopathy) in a patient with metastatic melanoma after using DCA for only 1 month (1200mg/day) along with high doses of vitamin A (150,000 IU/day) and it took over 8 months for the person to recover which involved physical therapy. I have not personally seen this. A personal communication with the author of this reported revealed that the patient had lived for over 3 years with this metastatic disease which, by conventional standards, is considered extremely impressive (i.e. above average). Nonetheless, it is strongly advised that patients need to be medically monitored while using DCA!
Another more common side-effect when DCA is used orally, because of the vinegar-like properties, it may irritate the stomach and especially in those who are sensitive already. It may be advised that in interested patients, that a stomach protective medicine be used alongside DCA.

Some of the published data

In mainstream literature there have been 5 cases in patients with brain tumors (i.e.Glioblastoma) where 3 patients appeared to respond on MRI scan and 4/5 were stable after 15 months. DCA was used alongside their conventional treatment program. There is also a case report of a patient with Non-Hodgkin’s Lymphoma Stage IV who has gone into remission after beginning DCA alone. There are other medical centers, like myself, who have yet to publish some of their positive findings in journals (which I will to do in the near future).
Newer data reported positive response in bile duct cancer (cholangiocarcinoma) and in helping with pain even when conventional methods have failed.
According to research from Dr. Michelakis in Alberta, it was shown that approximately a 3 month period of time was needed before DCA can be detected in the blood when used orally. Perhaps it better accumulates in tissues and the cerebral spinal fluid, which is not common or more difficult to test. I suspect that an initial loading dose by intravenous injection may be needed followed by a maintenance oral dose in most patients to attain an optimal therapeutic effect. The intravenous route may be an ideal means for patients who are able do this followed by an oral maintenance dosing program (i.e. the same has been observed with the use of vitamin C oral vs intravenous)

Together with other treatments appears ideal

I suspect the ideal situation for most using DCA is combined together with chemotherapy/radiation, immune-system, and related anti-cancer protocols as they may better enhance each other. I know that most oncologists warn patients about negative interaction concerns especially when dealing with experimental agents like DCA, but there are creative ways of cycling situations (i.e. breaks in between) for those that are worried and want to do both. There has been some more recent test-tube research showing that DCA is OK with Temozolomide, 5-FU but not with cisplatinum and doxorubicin, however, in another paper it synergized or worked well with cisplatinum and topotecan. There is not enough data either for or against the use of DCA with chemotherapy agents (just like most drugs), so it does become a person’s individual choice. Like my patient with brain cancer who has taken DCA together with her chemo, her choice has translated to an above average response.

Final Thoughts

DCA appears to have a better affinity for targeting cancers in the brain & nervous system for some reason (whether it started or spread there) and it also appears to work quickly when the conditions are right which is why a whole-person approach to cancer is important. In patients with cancers which have tendencies for spreading to the brain and central nervous system (i.e. advanced lung, melanoma, kidney, and breast cancers) DCA may also have potential for acting as a preventative or protective agent as well? To my knowledge only radiation is used in this capacity.  Some of my colleagues are using DCA for other types of cancers and are reporting some interesting findings – again using a combination approach appears the ideal way to go!
Because DCA is a prescriptive item in Canada and the US, people who are interested in its use need to be evaluated by a licensed healthcare professional and preferably by one who has cancer care experience. LEMMO Integrated Cancer Care Inc has been pioneering the use of DCA by intravenous injection since 2008 and this route may hold an added key in helping patients in more acute situations, where time is critical to achieve a quicker therapeutic effect.
