Dr. Patrick Vickers is the Director and Founder of the Northern Baja Gerson Clinic (Gerson Therapy). His mission is to provide patients with the highest quality and standard of care available in the world today for the treatment of advanced (and non-advanced) degenerative disease. His dedication and commitment to the development of advanced protocols has led to the realization of exponentially greater results in healing disease. Dr. Vickers, along with his highly trained staff, provides patients with the education, support, and resources to achieve optimal health.

Dr. Patrick was born and raised outside of Milwaukee, Wisconsin. At the age of 11 years old, after witnessing a miraculous recovery from a chiropractic adjustment, Dr. Patrick’s passion for natural medicine was born.

Dr. Patrick obtained his undergraduate degrees from the University of Wisconsin-Madison and Life University before going on to receive his doctorate in Chiropractic from New York Chiropractic College in 1997.

While a student at New York Chiropractic College(NYCC), Dr. Patrick befriended Charlotte Gerson, the last living daughter of Dr. Max Gerson, M.D. who Nobel Peace Prize Winner, Dr. Albert Schweitzer called, ” One of the most eminent geniuses in medical history. “

Dr. Gerson, murdered in 1959, remains the most censured doctor in the history of medicine as he was reversing virtually every degenerative disease known to man, including TERMINAL cancer.

Upon graduating from NYCC in 1997, Dr. Patrick went on to study the Gerson Therapy directly under Charlotte Gerson at her home in San Diego, California. While living with Charlotte, Dr. Patrick spent several months going through Dr. Gerson’s handwritten files of all his active patients from 1910-1959; files that Charlotte has kept in her home to this day. Included in those files were hundreds of handwritten letters from Nobel Peace Prize Winner, Dr. Albert Schweitzer, to Dr. Max Gerson. Schweitzer and Gerson were best friends after Gerson cured Schweitzer’s wife, Helena, of terminal tuberculosis when she had just 3 months to live.

Gerson also cured Schweitzer, himself, of severely advanced diabetes, in SIX weeks, eight years before Schweitzer won the Nobel Prize.

After several months of studying Dr. Gerson’s files, and several more months interning at the Gerson Clinic, Dr. Patrick opened chiropractic and Gerson clinics in Peru, Guatemala and Mexico before returning to the United States, in 2008, to open up this non-profit organization dedicated to educating the public on the Gerson Therapy.

Since that time, Dr. Patrick has been traveling around the world lecturing at international embassies, Latin American medical schools and other miscellaneous venues. More information at: http://www.gersontreatment.com/

Immune-Boosting Therapy Ineffective for Some with Melanoma

Friday, June 10th, 2016

 

Holistic-Health-Show-with-Dr-Carl-O-HelvieIn a new study presented at the American Society of Clinical Oncology (ASCO) this month researchers concluded that patients failing to respond to treatment using their own immune cells to destroy tumors, called tumor infiltrating lymphocytes, share changes in mechanisms that switch genes on or off in those cells. They said a pattern of “gene dysregulation” causes immune T cells to turn back to an immature state, making them less effective against metastatic melanoma. Immunotherapies ordinarily enhancem, not disrupt, the abiulity of T cells to identify and destroy cancer cells the same way they would an invading virus.

Researchers stated “Our research offers key evidence for genetic and epigenetic dysregulation as a reason these powerful immune therapies fail to work for so many people with widespread melanoma. ” He continued on to say that immune-based therapies in recent decades has increased the number of people  with advanced melanoma surviving longer that 5 years from 10 to 30 percent. However, immunotherapies still fail  and part of the problem is attributed to tumor cells suppressing the T cell populations that enable immunotherapy. Treatment failure was also believed to be related to factors involved in regulating gene activities tied to T cell function and this research looked to that area for study.

Analyzing genes in 24 melanoma patients researchers searched for patterns of changes in the epigenetics, or chemical modification to the DNA code that assist in controling which genes are turned on and which genes are turned off. Researchers goals was to find evidence that might explain the lack of response to immune boosting therapies in such patients.  Researchers found more than 60 epigenetic changes as well as 10 changes in gene activity that were most common to people for whom immunotherapy failed. Many  of the changes were known from previous research to control the process by which immature cells become either CD4 or CD8 immune T cells. Both are essential in immunotherapy The researcher proposes that these changes lead to T cell malfunction.

Thew next study will continue to analyze epigenetics and confirm their findings in larger numbers of people with advanced melanoma. They believe “If our research is confirmed, it suggests that by modifying the genetic or epigenetic alterations we have identified, we can potentially turn treatment non-res0onders into responders and broaden the success that immunotherapies are having against melanoma and other cancers.”  Researchers also say the procedure could have the advantage of being performed in the patients T cells while the cells are grown in the lab and before being injected into the patient, presenting a potentially safe and convenient treatment option.

Origins of Cancer Uncovered.

Wednesday, February 3rd, 2016

logo1267406_mdA new study reported in Science concluded that researchers had visualized the origin of cancer, from the first affected cell and watched its spread in a live animal. This could change the way they understand cancer and lead to new early treatment before the cancer has invaded.

Researchers queried why some cells already have mutations seen in cancer, but do not fully behave like the cancer. They continued “We found that the beginning of cancer occurs after activation of an oncogene or loss of a tumor suppressor, and involves a change that takes a single cell back to a stem cell state.”  That change involving a set of genes could be targeted to stop cancer from ever starting.

Over time researchers imaged live zebrafish to tract development of melanoma and all had the human cancer mutation BRAFV600E–found in most benign moles–and had also lost the cancer suppression gene p53. Researchers engineered the fish so that individual cells would floresce green if a gene called crestin was turned on that indicated activation of a genetic program characteristic of stem cells. This program normally turned off after embronic development, but occasionally for some unknown reason crestin and other genes turned back on in certain cells. The researcher said “Every so often we would see a green spot on a fish.” When we followed them, they became tumors 100 percent of the time.”

They found that these early cancer cells are the crestin and the other activated genes are the same ones turned on during zebrafish embryonic development and these genes also get turned on in human melanoma. They believe these finding will lead to a new genetic test for suspicious moles to see if the cells are behaving like neural crest cells that would indicate the stem cell program has been turned on.

They postulate a new model of cancer formation that goes back to the concept of field-cancerization. In this model the normal cell vecomes primed for cancer when onvogenes are activated and tumor suppressor genes are silenced or lost, but the cancer develops only when a cell in the tissue reverts to a more primitive, embreyonic state and starts dividing and this model may apply to most if not all cancers.

Do Antioxidants Cause Malignant Melanoma to Metastasize

Wednesday, October 14th, 2015

Logos 005A new study published in Science Translation Medicine concluded that antioxidants can double the rate of melanoma metastasis in mice and reinforces previous research that antioxidants hasten the progression of lung cancer.  Researchers further said that those with cancer or the high risk of cancer should avoid   nutritional supplements that contain antioxidants. Because it was known that free radicals can cause cancer, the research community assumed that antioxidants that destroy them, provided protection against cancer. As a result many nutritional supplements included antioxidants as a cancer prevention.

Now research shows this not to be true. The current study on melanoma, the worst type of skin cancer, found that antioxidants doubled the rate of metastasis in malignant melanoma and as opposed to the lung cancer study the primary melanoma tumor was not affected. Researchers said “We have demonstrated that antioxidants promote the progression of cancer in at least two different ways.” They protect healthy cells from free radicals that can turn into malignancies but may also protect a tumor once it has developed. Thus, taking nutritional supplements containing antioxidants may unintentionally hasten the progression of a small tumor or premalignant tumor, neither of which is possible to detect. Thus, they say those recently diagnosed with cancer should avoid antioxidant nutritional supplements.

The role of antioxidants is particularily relevant with patients who have melanoma because melanoma cancer cells are know to be sensitive to free radicals and alsoi because the cells can be exposed to antioxidants by non-dietary means . “Skin and suntan lotions sometimes contain beta carotine or vitamin E, both of which could potentially affect malignant melanoma cells in the same way as antioxidants in nutritional supplements.”  The role of lotions on cancer and the effect of antioxidants on cancer are ongoing in research by this orgainzation.

NB:It is interesting that research published April 9, 2014 on this site concluded that vitamin A (beta carotine) prevented normal cells from reverting to cancer cells.

New Potential Treatment Target for Melanoma Discovered.

New Potential Treatment for Melanoma

A new study published in the journal Clinical Cancer Research reported that researchers found high levels of an enzyme, interleukin-3  induced T-cell kinase (ITK) in melanoma cells that when blocked in pre-clinical studies in mice, reduced the cancer’s growth. This enzyme has not previously been explored as a driver of solid tumors and the researchers are hopeful blocking of the enzyme can be an effective treatment because one drug blocking the enzyme in blood and other cancer’s has been approved. Researchers said “We have discovered that ITK is highly expressed in melanoma even though it was thought to be restricted to immunity cells, and when you inhibit it, you decrease growth.” Five year survival rates for melanoma range from 98 percent to 16 depending on whether the cancer is localized or has spread and some treatments become ineffective so new treatments are needed.

Is Melanoma Linked to Socioeconomic Factors and Fashion Trends?

Friday, October 10th, 2014

Retrospective research published in a recent issue of the American Journal of Public Health concluded that extenuating factors such as socioeconomic and fashion trends  have contributed to the increase of melanoma over the past century. Believing that early diagnosis and improved reporting practices  do not fully explain the steady increase in melanoma they explored factors that may also have contributed to the increase in the United States. These included the trans-formative effect of socioeconomic trends dating from the 1900’s such as clothing styles, social norms, medical paradigms, perceptions of tanned skin, economic trends, and travel patterns. For compoarison between periods they estimated percentage of exposed areas of the body. for example, early in the 20th century clothing almost totally covered the body from head to toe and porcelain skin was favored over tanned skin that was associated with the lower class who often worked outside. Changes in medical practice also added to shifts in attitudes and practices. For example, “In the early 20th century, sunshine became widely accepted as treatment for rickets and tuberculosis and was considered to be good for overall good health.”  The public translated this into a desire for tanning  and at the same time people began enjoying more leisure time outside and favored swimwear and sports that covered less of the body. Graphs tracking the incidence by year and percentage of estimated skin exposure show a parallel between these changes in lifestyle and belief and the rise in melanoma.

Reason Why People with Red Hair Have a Higher Risk of Developing Melanoma?

Wednesday, August 28th, 2013

logo1267406_mdA new research study published in Molecular Cell concluded that  a persons skin pigment, which determines hair color and skin tone, is influenced by the melanocortin-l (MClR) gene receptor. and those with red hair have a mutation in MClR accounting for the red hair. This same MRlC mutation also promotes an important cancer-causing pathway and helps to explains the molecular mechanism that underlies redheads well-known risk of developing melanoma

The researchers found from cell culture and mouse model research that under normal circumstances MClR was binding to PTEN, a well known tumor suppressor gene. PTEN acts to safeguard against cancer,but in those without PTEN, the end result is elevated signaling in the cancer causing P13/AKt pathway. Researchers then demonstrated that MClR-RHC mutations found in red-haired people lacked this protective mechanism., “As a result, upon UVB exposure (that can damage DNA and lead to melanoma), we saw an increased destruction of PTEN in the mutated pigment cells.” They also found that in the same MCiR/RHC pigment cells, elevated P13K/Akt activity was boosting cell proliferation and synchronizing with another well-known cancer mutation in the BRAF gene (found in close to 70% of all melanoma) to accelerate cancer development. Other researchers have also recently found that expression of the BRAF gene mutation in the melanocytes of mice carrying a mutant MClR gene led to a high incidence of invasive melanomas/ “Together, our findings provide a possible molecular mechanism as to why red-haired individuals harboring MCLR mutations are much more susceptible to UV-induced skin damage than individuals with darker skin, resulting in a 10-to-100 fold higher frequency of melanoma.”

Does a History of Non-Melanoma Skin Cancer Lead to An Increased Risk of Other Primary Cancers?

Friday, May 3rd, 2013

logo1267406_mdA prospective study from Brigham and Women’s Hospital reported in PLOS Medicine reported on an association between risk of second primary cancer and history of non-melanoma skin cancer in white men and women. They found that people with a history of non-melanoma skin cancer had a modest increase risk of getting cancer in the future, specifically breast and lung cancer in women, and melanoma in both men and women,

Data was analyzed from two cohort studies in the United States and followed over 46,000 men from June, 1986 to June 2008, and over 107,000 women from June, 1984 to June 2008. Over the period there were over 36,000 new cases of non-melanoma skin cancer, and over 29,000 new cases of other primary cancers. A history of non-melanoma skin cancer was significantly associated with a 15% higher risk of other primary cancers in men, and a 26% higher risk of other primary cancers in women.  When melanoma was excluded from the analysis, the rates change=d slightly, with a history if non-melanoma skin cancer associated with 11% higher rates of primary cancer in men, and a 20% higher rate of other primary cancers in women. Using statistical models to correct for multiple comparisons,  looking at individual cancer sites, they found that a history of non-melanoma skin cancer was significantly linked with an increase risk of breast cancer and lung cancer for women, and an increase risk of melanoma ion both men and women. However, because the study was observational the researchers advised caution about the results.

Melanoma Risk in Some Women May Be Reduced by Taking Calcium and Vitamin D.

Friday, July 8th, 2011

logo1267406_md

A study reported online in the June 27 issue of the Journal of Clinical Oncology concluded that a combination of calcium and vitamin D may cut the risk of melanoma by over 50% in some women who are high risk. Women at most risk of developing melanoma are those who have previously had a non-melanoma form of skin cancer (basal cell, squamous cell). The researchers believed that cancer cells might be present in women who had previously had non-melanoma waiting to develop into melanoma but if they took calcium and vitamin D the risk might be reduced. In the study 36,282 postmenopausal women between age 50 and 79 who were part of the Women’s Health Initiative study were studied. Women were given 1,000 mg of calcium and 400 IU of vitamin D daily. Over 7 years of follow-up women taking the supplements who had had previous non-melanoma reduced their risk of developing melanoma by 57 percent compared to similar women who did not take the supplements. The melanoma risk reduction was not seen among women who had not had earlier non-melanoma skin cancer. The researchers plan further research in which cancer cells will be exposed directly to calcium and vitamin D.

High Intake of Dietary Phosphate May Be Associated with Skin Cancer

Friday, April 2nd, 2010

logo1267406_md

Results of a study published in Cancer Prevention Research concluded that a high dietary intake of phosphate promotes tumor formation in an animal model of skin cancer.

Researchers applied a carcinogen found in cigarette smoke (dimethylbenzanthracene) to the skin of mice and then applied another chemical that stimulates cell growth. Mice were then fed a high phosphate diet (1.2% by weight) or a low phosphate diet
(0.2 percent). Those fed a high phosphate diet had 50 percent more skin papilla (initial stage of skin cancer development) compared to those on a low phosphate diet.

Although phosphate is a very important nutrient its intake has
increase dramatically over the past 30 years according public health researchers who say it has been added as an additive in processed foods such as meats, baked goods and soft drinks.

The researchers estimated a human dietary equivalent to the high phosphate diet of the mice would be 1,800 milligrams daily and that is a level many humans match or exceed. The human equivalent of a low phosphate diet would be 500 milligrams.

In 2006 the Department of Agriculture said the average phosphate intake of American male and females over two years of age was 1,334mg and the recommended daily allowance was 1,250 for pre-teens and teenagers and 700mg for adults.

The authors said that a low phosphate diet may help prevent cancer based upon these results obtained with a mouse model.
