Cannabis Extract Fights ‘Incurable Form’ of Leukemia

Publié le 2 Mai 2014

A remarkable case report documents a 14-year old girl who, after 34-months of chemo, radiation and bone marrow transplant treatments, was given up for dead. Her family discovered research on cannabis extract, and before she died of a secondary complication of her original treatment, used it successfully to put her leukemia into remission.

There are plenty of anecdotal reports of the successful use of cannabis in treating cancer, but few cases occur under conventional medical supervision, and virtually none make it into a peer-reviewed biomedical journal as a case report.

Remarkably, however, just such a case was reported in Case Reports in Oncology last year, and involved a 14-year girl diagnosed with a form of cancer of the white blood cells known as acute lymphoblastic leukemia (ALL).

Despite a high remission rate for ALL after 5 year of 94% in children and 30-40% in adults using conventional combination chemotherapy, this particular child was diagnosed with a very aggressive (i.e. conventional treatment resistant) form of ALL (positive for the Philadelphia chromosome mutation).

After undergoing a protracted series of unsuccessful conventional treatments over the course of 34 months – including a bone marrow transplant, aggressive chemotherapy and radiation therapy — the girl’s case was pronounced ‘incurable,’ with the patient’s hematologist/oncologist stating that she “suffers from terminal malignant disease,” expecting her condition to progress rapidly towards death.

Because the family received no other suggestions for treatment beyond palliative care, they decided to do research on their own, stumbling on a paper published in Nature Reviews: Cancer in 2003 titled, “Cannibinoids: Potential Anti-Cancer Agents,” which encouraged them to administer oral cannabinoid extracts to the patient. According to the case report:

“The family found promise in an organization known as Phoenix Tears, led by Rick Simpson who had treated several cancers with hemp oil, an extract from the cannabis plant. Rick worked with the family to help them prepare the extract.

With Rick Simpson’s assistance, the family used cannabis oil extract for the next 78 days, with regular monitoring of the blast cell count, the primary indicator of the malignant progression of the disease process.

The figure below shows the successful suppression of the blast cells using cannabis extract.

Clearly, the cannabis extract was effective at inhibiting the uncontrolled proliferation of the girl’s leukemia, without the highly toxic side effects of conventional treatment.

Sadly, however, on day 78, the 14-year old passed away as a consequence of bleeding associated with bowel perforation, and ultimately the lasting adverse effects of the original 34 months of aggressive treatment she had underwent previous to cannabis.

In the discussion portion of the case report, the authors noted,

“The results shown here cannot be attributed to the phenomenon of ‘spontaneous remission’ because a dose response curve was achieved… These results cannot be explained by any other therapies, as the child was under palliative care and was solely on cannabinoid treatment when the response was documented by the SickKids Hospital. The toxicology reports ruled out chemotherapeutic agents, and only showed her to be positive for THC (tetrahydrocannabinol) when she had ‘a recent massive decrease of WBC from 350,000 to 0.3’ inducing tumor lysis syndrome, as reported by the primary hematologist/oncologist at the SickKids Hospital.”

The study authors believe this therapy should be viewed as “polytherapy,” owing to the fact that a wide range of cannabinoids have been found within resinous extract, which demonstrate a variety of anti-cancer properties, e.g. anti-angiogenic, anti-proliferative, etc. They further acknowledged the potential for the profound superiority of cannabinoid therapy to conventional treatments:

“It must be noted that where our most advanced chemotherapeutic agents had failed to control the blast counts and had devastating side effects that ultimately resulted in the death of the patient, the cannabinoid therapy had no toxic side effects and only psychosomatic properties, with an increase in the patient’s vitality.”

    Few experiences are more devastating than a cancer diagnosis. A leukemia diagnosis can be especially jarring, given that we typically hear of it in movies as a predator of children, even though the medical community has found that children have the highest state of remission at 94 percent, with adults at up to 40 percent after five years.

    A cancer of the blood, leukemia affects the bone marrow, red blood cells, white blood cells and the cells that cause clotting. Its symptoms include chills, weakness, susceptibility to infection, weight loss, bruising, swollen lymph nodes and bone pain.

    Chemotherapy and radiation are often suggested by care teams to help put the disease into remission; however, recent studies have also cited the benefit of cannabinoids or marijuana. The National Cancer Institute (NCI) even has a page dedicated to cannabis and cancer, explaining the benefits and risks of marijuana and CBD oil.

    Better treatments for patients

    A 2017 study in the International Journal of Oncology found that when chemotherapy was combined with cannabinoids, the potency of the drugs was “slightly improved.” Even more impressive, the research team found that even when used alone, THC and cannabidiol killed cancer cells. The authors of the study wrote: “Phyto-cannabinoids possess anticancer activity when used alone, and a number have also been shown to combine favourably with each other in vitro in leukemia cells to generate improved activity.”

    An option for palliative care

    A 2013 study showcased the power of cannabis in palliative care, citing a case of a 14-year-old patient whose failing health wasn’t responding to chemotherapy and radiation treatment after being diagnosed with Acute lymphoblastic Leukemia (ALL). The family started giving the patient cannabinoid extracts by mouth.

    Interestingly, after 15 days, doctors observed that the patient had a decrease in the need for morphine and an increase in euphoria and alertness. The cannabidiol seemed to help the patient in the weeks before she passed away. Researchers noted that the patient died of a secondary infection, and the patient’s leukemia seemed to be in remission.

    Ultimately, whether or not to use cannabis in treatment comes to the all-important discussion between patient and doctor. With more clinical trials around the world focusing on marijuana, hopefully, new research will shed light on effective ways to combat the disease and keep loved ones around for many more years to come.
