Leukemia by Ray Sahelian, M.D. - A Natural Approach to Leukemia

Leukemia is a cancer of the blood cells. Normally, blood cells are made in an orderly, controlled way. When leukemia develops, the bone marrow produces abnormal cells; therefore, the cells that are responsible for fighting infections and preventing bleeding are not made correctly.

Leukemias are classified as acute or chronic; an acute leukemia progresses more rapidly. They are also classified by the type of white blood cells in which they arise -- lymphoid cells or myeloid cells. There are four primary types of leukemia:

Acute lymphocytic leukemia (ALL)
Acute myeloid leukemia (AML)
Chronic lymphocytic leukemia (CLL)
Chronic myelogenous leukemia (CML).

In addition, there are other forms of leukemia that are rarer. 

Diet and Leukemia
Regular consumption of fruits and vegetables during the first two years of life is associated with a reduced risk of childhood leukemia.

Supplements and Herbs for Leukemia
Research regarding the use of supplements to prevent or treat leukemia is at its infancy, hence no confident statements can be made. My intent is to mention a few that have been studied.

Mangosteen herb

Antioxidants --Children being treated for acute lymphoblastic leukemia seem more able to deal with their treatment if their levels of antioxidants don't drop too much.        
     Kids with leukemia do not take enough antioxidants, which raises their risk of side effects during chemotherapy. Chemotherapy produces changes that stress the body's antioxidant defense system. Therefore, it's important that the diets of cancer patients contain adequate amounts of antioxidants. In a 6-month study, the researchers examined antioxidant intake and chemotherapy side effects in 103 children with acute lymphoblastic leukemia (ALL), the most common cancer in kids. During the study period subjects ingested vitamin E, total carotenoids, beta-carotene, and vitamin A in amounts that were 66, 30, 59, and 29 percent, respectively, of the US recommended dietary allowance. Greater intake of vitamin C was associated with fewer therapy delays, less side effects, and fewer days spent in the hospital. Similarly, the risk of infection and side effects decreased as vitamin E and beta-carotene intake increased.

Green tea and Leukemia
Green tea may help treat a form of adulthood leukemia. Doctors at the Mayo Clinic in Rochester, Minnesota, found that of four patients who started drinking green tea or taking green tea extracts, three showed clear improvements in their condition in the following months. The patients all had chronic lymphocytic leukemia, or CLL, a form of leukemia that usually arises during or after middle-age and typically progresses slowly. Like all types of leukemia, chronic lymphocytic leukemia is a cancer of the blood and bone marrow, in which abnormal white blood cells replace healthy blood cells. What's particularly interesting about these four cases, according to Dr. Tait Shanafelt, is that the patients all started using green tea on their own, after hearing media reports about a lab study Shanafelt and his colleagues conducted. That study showed that one compound found in green tea, known as EGCG, was able to kill cancer cells that were taken from chronic lymphocytic leukemia patients and put in a test tube with the tea compound. After the findings were published, the doctors became aware of four chronic lymphocytic leukemia patients at their center who had started using green tea products and seemed to be doing better. In interviewing the patients and reviewing their records, the doctors found that three showed signs of a regression in their cancer after they started to drink green tea or take green tea capsules. The fourth had an improvement in her white blood cell count, though her disease remained unchanged by standard criteria. In one case, the patient had been showing progressive swelling in her lymph nodes - one of the characteristics of chronic lymphocytic leukemia - before she starting taking green tea capsules twice a day. Over the next year, her lymph nodes steadily decreased in size. These cases alone cannot prove that green tea or its extracts conferred the benefits. An answer to that question, he said, awaits the outcome of an ongoing clinical trial he is leading. The study, sponsored by the National Cancer Institute, is testing the effects of a purified EGCG extract in treating chronic lymphocytic leukemia.

Cause of Leukemia
There are many causes of leukemia, from exposure to toxins to viral infections.
   Living near a fuel station may quadruple the risk of acute leukemia in children. French scientists who carried out a study of more than 500 infants found that a child whose home was near a fuel station or vehicle-repair garage was four times as likely to develop leukemia as a child whose home was further away. And the longer a child had lived nearby, the higher the risk of leukemia seemed to be. The prevalence of childhood leukemia is four in every 100,000 children, but it is the most common type of childhood cancer in developed countries. Few clear risk factors have been identified for the childhood variant, but exposure to benzene in the workplace has been identified as a possible factor in leukemia in adults. The risk appeared to be even greater for acute non-lymphoblastic leukemia, which was seven times more common among children living close to a fuel station or commercial garage. SOURCE: Occupational and Environmental Medicine, September 2004.
   Power lines can cause a small increase in the risk of childhood leukemia. Other leukemia causes are radiation and benzene, and chemotherapeutic agents. People who spend years using older permanent hair dyes may have somewhat higher odds of developing leukemia.
   Living near a high-voltage power line roughly doubles the risk of childhood cancers such as leukemia.
 
  Women with early breast cancer who receive higher-than-standard doses of two chemotherapy drugs (epirubicin and cyclophosphamide) as "add-on" therapy are at increased risk of subsequently developing cancer of the blood. Although add-on therapy with these drugs for early breast cancer has increased the number of long-term survivors, a small risk of secondary acute myeloid leukemia (AML), with or without a pre-leukemia known as myelodysplastic syndrome (MDS), has been identified.
   Greater body size significantly increases the risk of myeloid leukemia. Researchers studied data from a cohort of 40,909 adults who were followed for an average of 8.4 years. The incidence of myeloid leukemia was roughly five times higher among overweight and obese individuals than among individuals with normal or low weight. Specifically, the risk of myeloid leukemia increased 83 percent for every 10-kilogram increase in fat-free mass, and 35 percent per 10-centimeter increase in waist circumference.
   A study for the first time hints that maternal infection with Helicobacter pylori -- the bacterium that causes most cases of stomach ulcers -- is associated with an increased risk of childhood leukemia in the offspring. Leukemia makes up 25 percent of all childhood cancers worldwide and so-called acute lymphoblastic leukemia (ALL), the most common form of the blood cancer, comprises about 80 percent of all childhood leukemias.
   Exposure to pesticides in the womb or as a child can double the risk of developing acute leukemia. Children born to women who used insecticides in the home while pregnant and after the birth were nearly twice as likely as other youngsters to develop leukemia. Even insecticidal shampoos to kill head lice raised the odds of the disease.
   A mother who contracts influenza, pneumonia, or a sexually transmitted disease around the time of pregnancy appears to be at increased risk of having a child that will develop leukemia.
   Maternal Epstein-Barr virus (EBV) reactivation may be associated with a proportion of childhood leukemia. What that proportion this may be has yet to be defined.
   Children who live close to an AM radio transmission tower may have an elevated risk of leukemia. American Journal of Epidemiology, August 1, 2007.
   Young children living near nuclear power plants have a significantly higher risk of developing leukemia and other forms of cancer
  
Children and leukemia
The chances of children being diagnosed with leukemia seem to be related to the number of infections they had in their first year of life. Dr. Eve Roman from the University of York and colleagues identified 455 children with leukemia diagnosed between 2 and 5 years of age, and found that 425 of them had a type called acute lymphoblastic leukemia or ALL. Children diagnosed with ALL had significantly more infectious episodes in infancy than did a comparison group of matched "controls" without leukemia.

Pollution and leukemia
A University of Texas study found a possible link between childhood leukemia and living close to the city's refinery row along the Houston Ship Channel. Living within two miles of elevated levels of 1,3-butadiene around the ship channel's petrochemical complex was associated with an increased incidence of childhood acute lymphocytic leukemia compared with those living more than 10 miles away. The substance 1,3-butadiene is used to make petrochemicals like ethylene.

Leukemia and Infections
Common infections that affect mothers and babies may trigger certain types of childhood cancers. Leukemia and brain tumors, leading cancers in children, occur in clusters, which suggests that outbreaks of infections are a contributing cause of the disease. These infections could be minor, common illnesses...such a cold, mild flu or a respiratory infection. Leukemia is the most common childhood cancer, accounting for nearly one third of all cases. Most of the rise has been in children ages 1 to 4. An infection in the womb or early in life could lead to cancer in young people who carry mutant cells that would make them more vulnerable to the disease. The virus would hit this mutant cell and cause a second mutation, prompting the onset of cancers like leukemia or brain tumors.

Viruses and Leukemia
Viruses of the retrovirus and herpesvirus families may potentially cause certain human leukemias and lymphomas. The human T-cell leukemia virus type 1 causes adult T-cell leukemia. Influenza virus may also be a cause.
    
From 1974 to 2000, peaks in the rate of the acute lymphoblastic type of leukemia (ALL) among children in the UK seem to have occurred immediately after influenza epidemics. Perhaps some childhood leukemia may be triggered by infection occurring close to the time of diagnosis of leukemia. The findings are based on an analysis of data from the National Registry of Childhood Tumours, which covers the entire childhood population of the UK. During the 27-year period covered by the study, the rate of childhood ALL increased by 0.7 percent annually, on average. However, the rate spiked upward slightly in 1976 and 1990, just after influenza epidemics. Journal of the National Cancer Institute, March 15, 2006.

Leukemia Symptom
Leukemia Symptoms usually develop fairly quickly in acute leukemia. Most cases of acute leukemia are diagnosed when the person visits a doctor after becoming ill. Chronic leukemia symptoms progress gradually and are generally not as severe as in acute leukemia. About a fifth of people with chronic leukemia do not have symptoms at the time of their diagnosis.
     Some symptoms of leukemia are due to deficiencies of normal blood cells. Others are due to collections of leukemia cells in tissues and organs. Leukemia cells can collect in many different parts of the body, such as the testicles, brain, lymph nodes, liver, spleen, digestive tract, kidneys, lungs, eyes, and skin. The following leukemia symptoms are common to all types: Unexplained fevers, night sweats, fatigue or low energy, low mood, easy bruising or bleeding, and weight loss. The first leukemia symptom may be vague, such as fatigue. Another vague leukemia symptom is malaise, just a general sense of not feeling well. A more serious leukemia symptom is excessive bruising.

Leukemia Treatment
Patients on Gleevec for chronic myelogenous leukemia can develop severe congestive heart failure.

Leukemia Research Update
Feverfew: weeding out the root of leukaemia.
Expert Opin Biol Ther. 2005 Sep;5(9):1147-52.
Malignant stem cells are central to the pathogenesis and perpetuation of acute myelogenous leukaemia (AML). Despite their crucial role, standard chemotherapy often does not target these critical cells and, thus, the 'root' of leukaemic disease is not eradicated. To derive better therapies, unique molecular features of malignant stem cells have been characterised for AML and evaluated with regard to ablation of disease. In the course of such studies, the compound parthenolide, which is derived from the medicinal plant feverfew, has recently been shown to preferentially induce AML stem cells to undergo apoptosis. Importantly, parthenolide had no discernable effect on normal blood cells. Thus, this naturally occurring agent may provide new avenues of investigation for the treatment of leukaemia. In this article, characteristics of parthenolide are reviewed.

The sesquiterpene lactone parthenolide induces apoptosis of human acute myelogenous leukemia stem and progenitor cells.
Blood. 2005 Feb 1.
Recent studies have described malignant stem cells as central to the initiation, growth, and potential relapse of acute and chronic myelogenous leukemia (AML and CML). Because of their important role in pathogenesis, rare and biologically distinct leukemia stem cells represent a critical target for therapeutic intervention. However, to date, very few agents have been shown to directly target the leukemia stem cells population. The present studies demonstrate that parthenolide, a naturally-occurring small molecule, induces robust apoptosis in primary human acute myelogenous leukemia cells and blast crisis CML (bcCML) cells while sparing normal hematopoietic cells. Furthermore, analysis of progenitor cells using in vitro colony assays, as well as stem cells using the NOD/SCID xenograft model, show that parthenolide also preferentially targets acute myelogenous leukemia progenitor and stem cell populations. Notably, in comparison to the standard chemotherapy drug Ara-C, parthenolide is much more specific to leukemia cells. The molecular mechanism of parthenolide -mediated apoptosis is strongly associated with inhibition of NF-kappaB, pro-apoptotic activation of p53, and increased reactive oxygen species (ROS). Based on these findings, we propose that the activity of parthenolide triggers leukemia stem cells specific apoptosis, and as such represents a potentially important new class of drugs for leukemia stem cells targeted therapy.

Immunomodulation with interferon-gamma and granulocyte-colony-stimulating factor or granulocyte-macrophage colony-stimulating factor, helps deal with refractory fungal infections in patients with leukemia.

A child living near a high voltage power line may run a higher risk of contracting leukemia — the most common childhood cancer. But while there is an increased incidence of leukemia in children whose home address at birth was within 200 meters of a power line, the study’s authors admitted they had not proved that proximity to the power lines was the cause. “There is an association between childhood leukemia and proximity of home address at birth to high voltage power lines,” the study concluded.

Flavonoids induce apoptosis in human leukemia U937 cells through caspase- and caspase-calpain-dependent pathways.
Nutr Cancer. 2004;50(1):90-100.
Flavonoids are polyphenolic phytochemicals that are ubiquitous in plants and present in the common human diet. They may exert diverse beneficial effects, including antioxidant and anticarcinogenic activities. In this study we tested the apoptotic activity of 22 flavonoids and related compounds in leukemic U937 cells. Several flavones but none of the isoflavones or flavanones tested induced apoptotic cell death under these conditions, as determined by reduction in cell viability, flow cytometry, and oligonucleosomal DNA fragmentation. Structure-activity relationship showed that at least two hydroxylations in positions 3, 5, and 7 of the A ring were needed to induce apoptosis, whereas hydroxylation in 3' and/or 4' of the B ring enhanced proapoptotic activity. At lower concentrations, these compounds were also able to sensitize these cells to apoptosis induced by tumor necrosis factor-alpha. Regarding the mechanisms, galangin, luteolin, chrysin, and quercetin induced apoptosis in a way that required the activation of caspases 3 and 8, but not caspase 9. In contrast, an active role of calpains in addition to caspases was demonstrated in apoptosis induced by fisetin, apigenin, and 3,7-dihydroxyflavone. Our data show evidence of the proapoptotic properties of some flavonoids that could support their rational use as chemopreventive and therapeutic agents against carcinogenic disease.

Induction of apoptosis by xanthones from mangosteen in human leukemia cell lines.
J Nat Prod. 2003 Aug;66(8):1124-7.
We examined the effects of six xanthones from the pericarps of mangosteen, Garcinia mangostana, on the cell growth inhibition of human leukemia cell line HL60. All xanthones displayed growth inhibitory effects. Among them, alpha-mangostin showed complete inhibition at 10 microM through the induction of apoptosis.

Induction of apoptosis in cancer cells by Bilberry (Vaccinium myrtillus) and the anthocyanins.
J Agric Food Chem. 2003 Jan 1;51(1):68-75.
Among ethanol extracts of 10 edible berries, bilberry extract was found to be the most effective at inhibiting the growth of HL60 human leukemia cells and HCT116 human colon carcinoma cells in vitro. Bilberry extract induced apoptotic cell bodies and nucleosomal DNA fragmentation in HL60 cells. The proportion of apoptotic cells induced by bilberry extract in HCT116 was much lower than that in HL60 cells, and DNA fragmentation was not induced in the former. Of the extracts tested, that from bilberry contained the largest amounts of phenolic compounds, including anthocyanins, and showed the greatest 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Pure delphinidin and malvidin, like the glycosides isolated from the bilberry extract, induced apoptosis in HL60 cells. These results indicate that the bilberry extract and the anthocyanins, bearing delphinidin or malvidin as the aglycon, inhibit the growth of HL60 cells through the induction of apoptosis. Only pure delphinidin and the glycoside isolated from the bilberry extract, but not malvidin and the glycoside, inhibited the growth of HCT116 cells.

Inhibition the growth of human leukemia cells by Lycium barbarum polysaccharide ( wolfberry )
Wei Sheng Yan Jiu. 2001 Nov;30(6):333-5.
The effect and the mechanism of Wolfberry polysaccharide on inhibiting the growth of human leukemia HL-60 cells were examined. Wolfberry could inhibit the growth of HL-60 cells in dose-dependent manner and decrease the membrane fluidity of the cell. Agarose gel electrophoresis of DNA from the cells treated with wolfberry revealed a "DNA ladder" and positive TUNEL test. The results showed that the apoptosis of HL-60 cells induced by wolberry maybe its important mechanism on anti-tumorgenesis.

Children who attend daycare regularly in the first few months of life are less likely to develop acute lymphoblastic leukemia, the most common form of the blood cancer, than kids who do not.  The most plausible explanation for why daycare seems to protect against leukemia is that it allows children to be exposed to common infections early in life.

Cytotoxic effects of Coptis chinensis and Epimedium sagittatum extracts and their major constituents (berberine, coptisine and icariin) on hepatoma and leukemia cell growth.

Leukemia questions
Q. I read your article about how parthenolide might be good for Leukemia patients. Do you know if they still have any clinical trials on this?? Also, would it help if I took supplements of parthenolide or is that a waste?? I have AML and am not doing well at all. I have tried bmt and all other treatments basically.
   A. Unfortunately, so little research has been done with natural herbs and supplements for leukemia treatment that it is very difficult to give any suggestions with any certainty. Please discuss with your health care provider the information on this leukemia page and then decide on a course of action.

Q. Your webpage on leukemia states that leukemia will increase the risk of gout. Why is this so?
   A. Leukemia leads to high uric acid levels which make one more prone to gout.

Q. I was diagnosed with Acute Myeloid Leukemia in 2004 - after much chemo went in remission and the cancer returned in 2006 - given much chemo. and was told I had a few days to live on 8/19/06.
